Great video. What do you do if the glasses do not fit physically on your face, or you do not see clearly that may be an adjustment to do with the lens itself? It seems like I can't get my medical insurance provider to get the glasses made correctly; pupils don't seem to be where the clear spot is on the lens, and they don't coordinate my eyes very well. Have had them remake the glasses up to two or three times in a row in the past. They don't used mechanical devices to detect the center my pupils like one out of business Eye Care place used to do decades ago.
I went to eye doctors in 2016 because my vision quality had suddenly dropped sharply. The eye doctor said I had perfect vision and he didn't understand why I was there...I had near 20/05 vision before I went in to get my vision checked. He laughed at me as he sent me away. Turns out this was the first sign of a massive brain tumor that would go on to take up 1/5 of my brain. I am lucky it wasn't cancerous...but I am so frustrated with that doctor. Do eye doctors normally ignore sudden drops in vision quality so long as it is 20/20?
So glad to see an optometrist not threatened by online glasses. I get the service opticians provide, but when they start refusing to give me my PD and trashing online stores to justify charging me 5x-7x the price I lose interest in giving them my hard earned $. I let myself fall for it a few years back and paid over $600 for a pair that is inferior to my $80 Zennis. I would gladly pay an optician a reasonable fee to help with size, fit, shape, PD, etc. for reasonably priced glasses, but instead I feel like I'm buying a car at a shady dealer. Thank you for being an honest optician. Happy to support your channel and happy for your success! Congrats on over 1M subs.
My husband is a retired optometrist, occasionally I helped out. Sometimes a whole family might come in for eye exams, they all had bad vision and it would have cost a fortune to fit them all in glasses! So we gladly slipped them a note with Zenni’s name on it!
I don't like to disrespect a professional, especially when they have treated me as a valuable customer for years. But when the discount chains became huge, I was going to order Varilux Transitions and the optometrist quoted something like $630. I told him, I value your care, your quality, and your attention to detail. But the same thing will cost me $375 at Costco, and while I can't expect you to match that, is there something we can do about this? He went to speak with the owner, and $630 became $425, with everyone quite happy. The invisible variations in everything and price are simply incredible, when so many of the products often are the same.
I hear that. There are a lot of factors that go into the economics and price of glasses, especially in a local shop that may be accepting things like insurance (lots of crazy issues with contracts). Perhaps I should do a video on it.
@@DoctorEyeHealth Please do! I was looking for someone to commiserate with wrt purchasing eyeglasses. It's so frustrating to find affordable glasses as someone with a high powered prescription with astigmatism. I also work with computers all the time so I deal with a lot of headaches while looking at screens for extended periods of times. I've had a lot of experience buying glasses online due to budget reasons but almost every website (for upmarket/branded glasses) is super scammy or doesn't have genuine products. Additionally, it seems like every website has a different version of the high index, trivex and all of the various coatings. Plus the hassle of getting things reimbursed through your insurance. I definitely value the expertise of the MD for making my more complicated prescription glasses but am frustrated that it comes at a prices that is several times that of online.
I think seconding this, I never really know what size lenses, what coatings and all I should be purchasing because every website seems to recommend a different option.
This video is fantastic. A while ago, I had to order glasses online because the glasses that I got from the eye doctor's office was way too big. They seemed big during the fitting, but the worker told me that if they were too big, they could be adjusted to fit me. When the glasses came in, they kept sliding down my face, even after adjustments. The office wouldn't take them back and I couldn't afford to buy a new pair from them, so I had to order a pair online. I watched a lot of videos, including many of yours, and used the tips that I learned to order a pair that fit me perfectly. Thank you.
One thing I would recommend is if you are considering Transitions as a lenses option I would try looking at sunglass frames first and finding multiple pairs you like. Probably over 90% of the time sunglass frames are available as eyeglasses as well. So now you want to see what one you like most as an eyeglass. Biggest mistake Transitions buyers make I feel is getting a frame that is way to small to be effective coverage making them bad sunglasses and it just doesn’t look natural as sunglasses. So this really fixes the issue.
When shopping online for glasses, I think the first measurement to look for is the total frame width to see if they’ll even fit. Then I’ll look at the bridge width, and then the lens dimensions. Having a mm ruler comes in handy (also useful for buying jewelry online). And if you have a flatter nose, you want to look for “low nose bridge” glasses.
I have had cataracts and have implants. Both are set for far vision and I have astigmatism. I like to shoot pistol on a range. I cannot see the sights clearly due to the settings. If had the reading lense on the dominant eye and the far lense on the non-dominant eye, do you think that would work? Would a third party optical place like Walmart do this for me with a standard prescription, or would I have to get a special one from the doctor? Any favorite brands for shooting glasses?
From my experience it's quite simple. Single vision - fill your boots! Anything that requires an accurate PD or fitting height such as PALs, digital lenses, bifocals etc. - proceed with caution! There's nothing worse than trying to adapt to an expensive pair of progressives where the PD is out by a couple of mm and you can't return them free of charge for a re-lens or refund.
GlassesOn app makes measuring very easy. Tried with 2 different phones couple times, and had same result every time. I ordered glasses with that measurement and it feels perfect
GlassesOn does a reasonable job, but it only measures binocular PD and uses the distance between the centre of the pupils. In most cases, this is sufficient for single vision lenses. For PALs however you need an accurate monocular PD that measures the distance between the visual axis. Often the visual axis is slightly medial to the centre of the pupil. A dedicated pupilometer will measure the corneal reflex light to determine this.
I always have this question: After you've received the glasses, how do you minor adjustment... like the nose pad, or even the arm so that it can be a perfect fit?
Most optical stores will do it. If they are nice, they will do it for free. Some businesses might charge a service fee. They will tell you since you did not buy from them, you are allowing them to service your glasses at your own risk.
It's always best to have them professionally adjusted. Most local places can help with this - sometimes for a small charge when it's a pair of glasses purchased elsewhere.
Are these just polycarbonate lenses, if not which ones are they? I have found i see the best & most clear with Nikon lenses, they are 2nd to contact lenses which i can no longer wear bc of severe dry eye. How would Zenni lenses compare to Nikon lenses? Thx
Hello, Dr Allen. I have a very important question to ask you. I’ve just started to wear a spectacle with progressive lenses. The lenses are from Zeiss and they are phenomenal! But I also have a powered sunglass from my earlier prescription. This sunglass is a single-vision one (for my nearsightedness) and the lenses are from Essilor Xperio. The power of farsightedness in this sunglass is almost the same as the new progressive one. Can I wear these sunglasses when I go outside? Or will it harm my vision because now I have a progressive vision? Please advise.
Except they’ve never ever, ever have gotten the prescription correct…the index is always off, the PD is too narrow or wide…just impossible. I go in to the brick and mortar shops now after attempting on line orders 6 times at 3 different on line companies.
Excellent instructional video! But I have to say that I am so tired of being "sold" on high index lenses. I order from an online eyeglass provider that thankfully allows me to order any of their lens options with my -9.50 prescription. Several years ago when I was low on cash (but high on diopters, LOL), I ordered their 1.56 index lenses in a progressive no less. I admit I was shocked that I couldn't tell the difference in my vision compared with 1.74 index lenses. No distortion (and boy how many times was I told there would be intolerable distortion), and no noticable weight increase (my secret was to order an 8g weight frame.) My latest online order was for 1.59 polycarbonate lenses and once again, they're completely fine, no issues, no complaints. It makes me sad to look back on years of paying as much as $800 for 1.74 high index lens progressives in frames from the "value line" frames from a local optician when my most recent order cost $77.85. And it makes me angry when I recall how many opticians and labs refused to make my lenses in anything less than 1.74 high index.
Sorry that you’ve had a bad experience in the past! Most people don’t notice a visual difference between lens materials, but some really do. I would say that high index lenses have as much to do with thickness and weight of the lens as they do with the clarity. Frame selection plays a huge role in the thickness and weight of the lenses, too. Generally, high index lenses for high prescriptions is going to provide a more comfortable and aesthetically pleasing experience for the wearer, and that is why I still recommend high index lenses (typically 1.60 or 1.67) for prescriptions at or above +/-4.00. That said, everyone is different and values different things, so I’m glad that polycarbonate has worked well for you!
Thank you for tips , it was really easy to order glasses )))) I paid express delivery $19 .. al total $75 , in the store the cheapest was $300 .... Do you guys feel the difference ?
How about a video for what is needed to order progressive lenses? This seems like the trickiest option. If not a video can your provide some details in a response to this message. Thanks.
Zenni, unfortunately, told me, "We are unable to produce prism for progressive or bifocal glasses". I've had to buy progressives with prisms from a store-based optician, at about three times the cost of what Zenni would probably have charged.
Just got some glasses today from my eye doctor. I had no idea about high index being important for strong prescriptions before. Both my eyes are about -7.00, and my last pair made me nauseous so I never wore them. They were pretty pricey but I got high index 1.67 lenses for these, so I hope that helps out!
How to order spectacles online 1. Pick up your phone, tablet or switch on your computer. 2. Book in for a sight test 3. Turn up to your eye test 4. Get dispensed with a decent pair of glasses by someone who is trained and knows what they are bloody doing. 5. Pay what you need to and wait 7 to 10 days (or 1 hour if your opticians has an on-site lab) 6. Pick up your glasses, have them adjusted to fit by someone who is trained, then bugger off. The end
And pay $800 for what costs $80 online. Life's full of choices, and sometimes "cheap" is the option you need. It'd be lovely if we all had the money to do this
When choosing frames I ALWAYS go in this order: 1. Prescription/use (finding a frame that fits the prescription and what you will use the glasses for). 2. Fit (selecting frames that fit your face and center your eyes well within the frame). 3. Style (things like shape of the frame, acetate vs metal, and color). I’m pretty against the notion of picking frames by starting with trying to pick a frame shape according to some nebulous idea of face shape. Wear what you want, as long as it fits your face and prescription!
The PD is the biggest problem, as they don't include this in the prescription in the UK, and they are sheepish about giving it to you. I've measured it myself, but never sure if 1-2mm either way makes so much difference. having said that, the last local shop I went to didn't bother measuring the PD either - they were basically just operatives for an online site in the same way I could do myself (better) in the comfort of my own home...
Yeah I understand where clinics are coming from. They are frustrated because they are middled by glasses manufacturers and insurance companies - they get paid very little for their time and expertise and then people don't buy glasses and instead buy elsewhere. A lot of eye clinics are at risk of going out of business because of this or they will have to drastically change their business models. With that being said, I understand why some clinics charge for the PD measurement (especially if they are using pupillometers which help measure PD with extreme accuracy) as they had to purchase that equipment and it isn't always cheap. But in order to do a refraction properly, the phoropter (instrument people use to measure the glasses rx), needs to be set for the correct PD anyway. So it is very much part of the refraction procedure. The only challenge is that the phoropter only works in binocular PD - where some people require monocular PD for the most accuracy in their lenses.
For a progressive or varifocal, 2mm will definitely make a difference. I would be wary of anyone dispensing varifocals without measuring PD using either a corneal reflex pupilometer or a digital alternative like Zeiss Visufit.
Hi! I'm really hoping you can help me out with a question that I can't quite figure out. On my prescription my pupillary distance says 68/65. I'm not sure if that means I need to pick one to enter as a single number PD or if I have to enter both numbers as a double number PD. Sorry if my question wasn't worded in a way that's easy to understand. This is my first time purchasing glasses online and I'm absolutely clueless
Great question! Thank you. The first number is distance vision PD, the second number is near vision PD. (In case you were getting reading only glasses, or bifocals etc)
What about vertical PD? My local place who gave me my full prescription including pupil distance, said it's ok buy online but never progressives because they cant measure the vertical location so it could be wildly inaccurate.
There is a lot to the economics of it. Of course the cost of overhead and paying local staff a living wage - that goes into the cost because the local shop has to make a profit. The quality of the materials and products they choose to sell plays a role as many local stores cannot even buy glasses from the vendors they use at a cost as low as some online opticals offer. The other factor people don't see is the control of insurance companies. Many clinics offer "vision insurance" which is offered through companies who also...own the frame, lenses, etc. And those insurance contracts require the stores to give large discounts on their products to the people who carry the insurance. So because of these large discounts - they local store has to increase their prices dramatically because otherwise they would LOSE money on selling glasses. And it would be illegal to charge a higher price for some customers vs others. SO the price of the glasses have to go way up for EVERYONE. And unfortunately, many insurance plans only reimburse the clinic/doctor about 35-40 dollars for their time in the exam room, which is why you see some doctors having to see a patient every 5-10 minutes (which I fear can drive poorer quality of care). That leaves the clinic in hope you would buy glasses from them to make up the difference. Again, it can get complex. Perhaps a good video?
@@DoctorEyeHealth I think it would be a great video, I guess with all the challenges you have... Is the model working for you? I know this was a sponsored video and I don't want you to lose your sponsors but is a zenni experience inferior? I'm fortunate in that I can afford to pay more for better quality care, but lots can't and is online "good enough"
@@RobertKirkpatrick84 I don't mind the docs being reimbursed for their time, education, and expertise. My primary care doc charges $100 per visit, so $70 is not unreasonable (IMO).
Thank you for this video. I needed some cheap-o glasses to get me through the time between cataract and retinal surgeries. It was helpful to spend only $100 as opposed to the $600 I spend locally.
Can you please do a video/review of the Renpho Eyeris Heated Eye Massager?? I would really love to know if it's safe to use and if it works! Thank you🥰
General Grey lenses or Amber Lenses are the classic colors for which you will see most sunglasses made. There are also Pink/red lenses and Green. Mostly user preference and what you would be using them for the most.
My head is awkwardly shaped and I've always had trouble finding classes as they are amost always too small even shopping larger sizes in person. I was gifted a pair that do actually fit, they are my favorite pair but I know they won't last forever so this will definitely be helpful as I know at least for now I don't have a prescription but sunglasses are very important with that UV protection ✌️
I keep seeing these magnetic Fram color changing glasses. I am intrigued but I don't know if I should bite the bullet or just be more secure with a good pair them maybe try a second pair out of pocket
Hi Doctor, you said that most people choose their lenses set for distance with monofocal lens implants with cataract surgery. Why is that? Why not near? It seems like it would make sense to have them set for near since you need the near vision for so many things including PUTTING YOUR CONTACTS IN. So, can you tall me why distance is better? Thank you.
Good question! This came up with a patient of mine yesterday. Some people do in fact choose to have single vision monofocal implants put in that are set for near instead of distance. In my experience, this works better for people who have already been moderately nearsighted their whole lives. That way they have already been used to wearing glasses to see in the distance. The challenge is that some people who choose this, later regret the decision. Which is something that no doctor wants. So when someone is thinking of having that type of lens put in, we usually review it with them many many times and also have them sign a form that we discussed everything with them too.
@@DoctorEyeHealth I see. I am far sighted and I have an astigmatism. I have been wearing glasses my whole life. My glasses have been set to make me somewhat near sighted. This gave my eyes more rest at reduced the tendency to cross. I am considering lens replacement now. I am considering monofocal lenses and trying to decide on near versus far. I have strongly been considering monovision with one set for near, and the other set for medium (computer) distance.
I recommend pair eyewear they are very good and their glasses are magnetic so they make sunglass toppers that just stick onto them and the glasses are only 60$ and very high quality
Hi! Could you mention how to order prescription swim goggles and what data (sph/cyl/axis) needs to be taken into consideration as online websites just mention -4 to -1, Appreciate guidance. Thanks
CNET has a good article on the best places to buy replacement lenses online. I just ordered from LensDirect, and will probably go with Lensabl for 1.74 high index Transitions in another frame.
My left eye is very weak my script reads Cyl + 4.00 the right is +1.25 I was going to get the 1.67 Varilux comfort lens but it only goes to Cyl +3.00. What lenses should I get?
Hey Dr.Allen! Do you have a video on which high index lenses you should be going with based on your individual prescription? Really enjoy your videos! Thanks!
Hello Dr Allen, hope you read my comment and solve the problem that I have🙏🙏. I have a myopia of -1.50 in both eyes and don't have any other problems with my eyes, my cornea thickness, and pupil diameter everything is ok, so now I want to go for Femto LASIK surgery to have a vision of 20/20. I searched a lot there are different comments so now I am scared and I don't know what to do but still I want that surgery to correct my vision completely. If I go for this surgery is there any risk of glare or halos or any other permanent problem in the future? is it worth doing this surgery or I should be with this -150 myopia and wear glasses?
If U choose standard lens you are not getting the option to get for oil resistant lens and if you choose their premium it is way too expensive so this is not so good. I have to get transition and progressive and wanted to get everything but is is coming up way too much😢😢😢😢😢
I love the Transitions brand of lenses too but another option that may be more affordable would be Zenni's own photochromic lenses - they are not "Transitions" brand but may work similarly in that they will change to darker lenses in the sunlight.
@@DoctorEyeHealth thanks but the glare and the UV bothers me alot and this is my first time ever seeing th optometrist. Also he says one of my eyes is weak so it's alot😞
Dang, I'mma gonna watch this one. Have you saw any people's vision changed b/c of v injuries or covid? I was severely injured by v but recovering after 2.5 years. 500 hours in hbot, triple therapy, ivm, ldn, maraviroc, statins. I dread seeing him. Hard to get checkups w/out breaking down with all that.
Thank you so much for such informative video, I do have a question regarding glasses that "my prescription is -3 cyl with 180degree axis both eyes" I am having tough time in getting adjusted to powered lenses because of first time, getting blurred vision every time I move my head because of axis change. any tips and tricks for me to resolve or minimise such problems...
I have purchased online glasses here in Germany, so far the experience has been great. In fact, besides the normal glasses I have also purchased special use-case glasses specifically for watching TV at about 2 m (SPH values with +0.50 added,) for computer usage (for focusing at arm's length distance, so with +1.50 added to my SPH values), and for reading (with +2.50.) In all of this I never changed the PD values though, yet the glasses all work great for me. After reading another comment here, I do wonder if for reading glasses one should better adequately shorten the PD distances? From what I can tell taking selfies with a ruler on my face, my interpupilary distance goes from about 68 mm when looking into the distance to about only 58 when reading.
Technically speak, yes, reading only glasses should have a smaller PD which can be measured easily with a millimeter ruler. Otherwise local eye clinics can help measure for it too. Otherwise the prismatic effect of the glasses may contribute to eye strain.
@@DoctorEyeHealthThanks a lot! Then from the same reasoning, the computer distance glasses should then also have their own smaller PD? But somewhere between that of normal glasses vs. reading ones? Or it does not matter much for those?
@@DoctorEyeHealth Ok just saw an older video of yours that you listed in the description (how to measure your PD) where you indicate that for reading glasses typically the rule is to substract 3 mm from the total interpupilary distance, and this matches what one of the Zenni pages says. I am realizing the selfie measurement I listed above for reading PD was way too small because my cell phone was way closer to my face, while for the normal PD photo the cell phone was far and with zoom. Thanks again!
You would probably have to go into a store for that. Tell them you dropped your glasses over a sewer grate or something and just have the frames, and need new lenses.
I've used Zenni for years for my kids and myself. It's almost always been great! I ran into a problem when I switched to progressive lenses. Zenni couldn't get them right. So, I strongly recommend Zenni, but only for single vision lenses.
@@DoctorEyeHealth They are slightly bigger than the cornea. So I think they kinda gravitate towards my lower eye lids and I feel it...I don't think that's a problem though
I feel like frames never fit me. I have a fat face but a skinny nose and all frame manufacturers think if your face is wide you also have a giant nose. So I either end up witn frames falling off my face or pinching/not cute.
I’m nearsighted (-0.5 in both eyes) with an astigmatism, my glasses are great for driving but for computer use my monitor is just far enough away that I want that astigmatism correction but when I wear my glasses it feels like it “focuses” my eyes further away than my monitor. Could I order a pair with a lower PD to “focus” my eyes to the screen? Similar to reading glasses even though I’d still want it to be a negative prescription?
Changing the PD of glasses can result in negative consequences to eyesight and comfort. It could even cause problems with the eye muscles leading to eyestrain and...depending on the person, could cause other issues with eye alignment and dominance perhaps. If someone is having problems up close, such as staring at a computer monitor, it would be best to have an assessment by a doctor to prescribe computer glasses with the appropriate powers. Changing the PD alone would not be appropriate.
Hopefully the Dr. will answer, but I think you need to adjust mostly the SPH values (not sure about the PD.) Computer glasses focus at about arm's length or slightly less, that is somewhere in the range 20-28", or 50-70cm. To have the focus at that distance, you'd need to ADD about +1.50 (for up-closer laptop usage maybe better +1.75) to your SPH values on both eyes, still preserving the exact same values you might have for CYL and AXS (if you have any astigmatism.) Hopefully he will corroborate or rectify this.
How do you measure glasses or know what the best measurements are if your current pair don’t have the numbers printed on the side? Or if the numbers have worn off?
With a ruler. Or try some frames on locally and take note of the numbers. How do you know what size shoe you wear? How do you know what size clothes you wear?
I would love to order online but I have a narrow face, like a kid. There is just nothing online if I add the sizes. Even in kid's section. 47-18-140...😅 It's so fustrating.
Hi Dr. Allen, Of course i do it. As an EE, i measure my own refractive state. This is how I went from 20/50 to 20/20. I know you do not understand the science of objective prevention. Zennioptical was essential to me.
@@DoctorEyeHealth Hi Dr. Allen, An EE is an Electrical Engineer, interested it the behavior of all eyes, with the goal of preventing entry into myopia.
How are they with complicated prescriptions? I am highly nearsighted with a -6.75 Sph, and strong astigmatism 2.75 cyl, 180 axis. I also wear progressives.
Something I think would've been nice to add was how accurate the prescriptions matched up to the lenses are in 2024!! I have an eye exam again this friday two years ago it was +4.25 in my left and a +5.25 in my right. I ordered a pair online two years ago, and they seem to be correct. I can get more for my money online but my biggest fear is I might have the wrong lenses and not noticed. Any thoughts?
I did a video a few years ago where I ordered glasses from about 6-7 different online vendors - there was some variability, but in my experience I had accurate lenses from Zenni (one of the reasons I worked with them on this video).You can always ask a local optical to check the accuracy - they may charge a small fee for this service but it would be one way to verify. In addition to the powers being accurate, when you have a higher prescription the fit of the the glasses also becomes more important, so hopefully getting glasses adjusted would help too.
@brucesmith9144 I actually don't use progressive lenses I think mine are just considered reading glasses. I have ordered from zenni and glassesusa. Same prescription and I would say the zenni pair felt stronger? Only problem I had with them was the frames were to small for me. Glassesusa I got a pair of raybans and lenses for like $250. I can't speak for the exact accuracy on them either but I'm going to the eye doctor Friday and will ask them to see how correct they actually are. I will say though that my eye doctor seems willing to just upsale everything a single pair from there with just polycarbonate lenses with rayban frames was gonna be almost $400!! Currently looking at another pair from glassesusa with polychromatic lenses and 1.67 index with frames for $260.
Does anti-scratch coating do anything? I always get LOTS of fine scratching even with coating, and cleaning with the microfiber cloth. Any recommendations to care for plastic lenses?
I'd always wondered about how to shop for and where to look for online classes and you answered every question that I had and then some more, thank you so much for making this video!
If you know the model, you may be able to find the measurements. I've noticed not all glasses have them. If all else fails can try some on locally and take note of the sizes. Really wish online stores would let you demo the frames because sometimes a few mm larger or smaller makes a difference.
I have two different pupillary distance numbers, ad I'm not quite sure which one is for right eye and which one is for left eye. Need to be sure before filling an online prescription. Could you please help me about this?
It is considered very safe, but it is a newer procedure and best to find a qualified refractive surgeon with a good history of success with that procedure.
Most of those Buddy Holly retro style frames don't have them i just got a new pair of Ray Bans and I prefer the no-pad design they have; those pads are a nightmare to clean and man, do they get dirty.
Thanks so much. Very informative. I've ordered from Zenni before, but prescription readers only. Your info will assist me when I order for prescriptives.
Does it matter with single vision +0,25 lenses to be off in PD in 1mm? I measured it myself, also my gf did it and went down with 62 mm. App says its 61mm but I have really dark eyes and it might be mistaken. But does 1mm in this case makes a huge difference?
I don’t think PD matters at all for single distance lenses.. it matters only for progressive lenses as you need to know what part of the lense you will be naturally looking through for distance.. the lense below that point gradually changing for close up vision
Hello Doc. Joe! THANKS for this. Can you talk about the importance of P.D.? It seems SO important that many eye doctors who also sell glasses simply won't give your P.D. until you buy a pair of $800 plus glasses from them. My eyes are so bad I MUST have multiple pairs for driving and reading. I cannot afford $800 each for four to six pairs of glasses. I must buy glasses on-line instead. So, the last time I went to the eye doctor, I developed a trick. I watched the doctor's assistant, and she did not alter the machine she used to develop my prescription once she was done. I waited for her to leave the room after putting dilating drops in my eyes, and then I got out of the chair and took a photo of the machine's settings -- which had my P.D. displayed on her side of the machine -- turns out the P.D. of my eyes is different! It is SO unacceptable that an eye doctor will not give you your P.D. unless you get very angry with them and remind them of the LAW here in Connecticut. Even then, they will deflect and not give you the P.D.
On my glasses the PD was way too small for me to read so I took a picture of it with my iPhone and then enlarged the picture. I've done the same for a lot of different items. I hope this will help someone else who is as challenged as I am by small print. Also, I'm 71 and I got a pair of the glow in the dark glasses as well. You're never too old to have a little fun.😉
Great video! I've ordered glasses from Zenni a number of times with good results. You've touched on the key issues; in particular taking measurements from an older pair of glasses that fit well makes it a lot easier to choose the right size frame. If you wear progressive lenses, it's a good idea to get adjustable nose pieces in case the height of the frame needs to be tweaked to better position the reading portion of the lens. The oil resistant AR coating is definitely worth paying a little extra for. 👍👍
Well the power of the progressives is based on the ADD of the lens written on the glasses prescription. The gradient or "power" in the different parts of the lens are based on the design of the progressive lens but is usually a gradual change - where the intermediate section is about 50% of the total ADD. Let me know if that makes senses or answers your question.
Thank you for this so much! Ive been struggling to find simple help with simple questions filling out Rx online, so much that I was about to go on a full study myself and a video for other people, lol! Google was zero help. Cheers!
Good God , are there any video guides that cut straight to the chase and tell you what you need to know in order to order online or are they all like this.
Honestly, it was really good to know about the lens index. Yeah, I knew that it was thinner and lighter, which isn't a huge deal for me, but the biggest thing you mentioned was motion sickness. I have ZERO depth perception, which would require extremely thick prism to correct, so I just don't bother (I was born with a lazy eye, it got surgically corrected, but between that and patch therapy, never fully fixed the problem - although I do hear that VR training for both kids and adults is doing amazing things). If I'm in a vehicle for longer than an hour, I start getting sick. Faster if I don't eat, and even faster if I'm sitting in the back seat of a vehicle (city buses can be rough too depending on how much of a lead foot the driver has).

Do you have any questions about finding glasses??? Please let me know!
Check out new frames and prices on Zenni - imp.i279709.net/oqWYQE
Not available with my PD and prescription 😢
Great video. What do you do if the glasses do not fit physically on your face, or you do not see clearly that may be an adjustment to do with the lens itself? It seems like I can't get my medical insurance provider to get the glasses made correctly; pupils don't seem to be where the clear spot is on the lens, and they don't coordinate my eyes very well. Have had them remake the glasses up to two or three times in a row in the past. They don't used mechanical devices to detect the center my pupils like one out of business Eye Care place used to do decades ago.
I went to eye doctors in 2016 because my vision quality had suddenly dropped sharply. The eye doctor said I had perfect vision and he didn't understand why I was there...I had near 20/05 vision before I went in to get my vision checked. He laughed at me as he sent me away.
Turns out this was the first sign of a massive brain tumor that would go on to take up 1/5 of my brain. I am lucky it wasn't cancerous...but I am so frustrated with that doctor.
Do eye doctors normally ignore sudden drops in vision quality so long as it is 20/20?
Please help. I have different PDs and don't know which to use when ordering online. Mine are 30.5/30.5 and also 61/58. PLEASE HELP!!!
I'm content with my current frames which are not worn out at all. Is there someplace I can send them in to have my new prescription installed?
I have worn glasses for 32 years now, this is one of the most helpful videos out there.
So glad to see an optometrist not threatened by online glasses. I get the service opticians provide, but when they start refusing to give me my PD and trashing online stores to justify charging me 5x-7x the price I lose interest in giving them my hard earned $. I let myself fall for it a few years back and paid over $600 for a pair that is inferior to my $80 Zennis. I would gladly pay an optician a reasonable fee to help with size, fit, shape, PD, etc. for reasonably priced glasses, but instead I feel like I'm buying a car at a shady dealer. Thank you for being an honest optician. Happy to support your channel and happy for your success! Congrats on over 1M subs.
100%
My husband is a retired optometrist, occasionally I helped out. Sometimes a whole family might come in for eye exams, they all had bad vision and it would have cost a fortune to fit them all in glasses! So we gladly slipped them a note with Zenni’s name on it!
Right! There is certainly a huge value in glasses purchased from a local, in-store optical, but it also may not be for everyone. And vice versa.
Kool.....under $100 online, over $400 at the store.
Are they good quality? I’m tired of buying my glasses out the store. My last pair I paid $400
@GorillaBlack4F yes they are good
@@stevek343 thanks 🙏🏾 a lot this will be my first time buying glasses online.
I don't like to disrespect a professional, especially when they have treated me as a valuable customer for years. But when the discount chains became huge, I was going to order Varilux Transitions and the optometrist quoted something like $630. I told him, I value your care, your quality, and your attention to detail. But the same thing will cost me $375 at Costco, and while I can't expect you to match that, is there something we can do about this? He went to speak with the owner, and $630 became $425, with everyone quite happy.
The invisible variations in everything and price are simply incredible, when so many of the products often are the same.
I hear that. There are a lot of factors that go into the economics and price of glasses, especially in a local shop that may be accepting things like insurance (lots of crazy issues with contracts). Perhaps I should do a video on it.
@@DoctorEyeHealth Please do! I was looking for someone to commiserate with wrt purchasing eyeglasses. It's so frustrating to find affordable glasses as someone with a high powered prescription with astigmatism. I also work with computers all the time so I deal with a lot of headaches while looking at screens for extended periods of times. I've had a lot of experience buying glasses online due to budget reasons but almost every website (for upmarket/branded glasses) is super scammy or doesn't have genuine products. Additionally, it seems like every website has a different version of the high index, trivex and all of the various coatings. Plus the hassle of getting things reimbursed through your insurance. I definitely value the expertise of the MD for making my more complicated prescription glasses but am frustrated that it comes at a prices that is several times that of online.
I think seconding this, I never really know what size lenses, what coatings and all I should be purchasing because every website seems to recommend a different option.
This video is fantastic. A while ago, I had to order glasses online because the glasses that I got from the eye doctor's office was way too big. They seemed big during the fitting, but the worker told me that if they were too big, they could be adjusted to fit me. When the glasses came in, they kept sliding down my face, even after adjustments. The office wouldn't take them back and I couldn't afford to buy a new pair from them, so I had to order a pair online. I watched a lot of videos, including many of yours, and used the tips that I learned to order a pair that fit me perfectly. Thank you.
One thing I would recommend is if you are considering Transitions as a lenses option I would try looking at sunglass frames first and finding multiple pairs you like.
Probably over 90% of the time sunglass frames are available as eyeglasses as well. So now you want to see what one you like most as an eyeglass.
Biggest mistake Transitions buyers make I feel is getting a frame that is way to small to be effective coverage making them bad sunglasses and it just doesn’t look natural as sunglasses. So this really fixes the issue.
When shopping online for glasses, I think the first measurement to look for is the total frame width to see if they’ll even fit. Then I’ll look at the bridge width, and then the lens dimensions.
Having a mm ruler comes in handy (also useful for buying jewelry online).
And if you have a flatter nose, you want to look for “low nose bridge” glasses.
I have had cataracts and have implants. Both are set for far vision and I have astigmatism. I like to shoot pistol on a range. I cannot see the sights clearly due to the settings. If had the reading lense on the dominant eye and the far lense on the non-dominant eye, do you think that would work? Would a third party optical place like Walmart do this for me with a standard prescription, or would I have to get a special one from the doctor? Any favorite brands for shooting glasses?
From my experience it's quite simple. Single vision - fill your boots! Anything that requires an accurate PD or fitting height such as PALs, digital lenses, bifocals etc. - proceed with caution! There's nothing worse than trying to adapt to an expensive pair of progressives where the PD is out by a couple of mm and you can't return them free of charge for a re-lens or refund.
so would not be a good fit for me then
I agree.
It's easy to measure the PD actually. I save so much money buying my own RX glasses online, I have been doing it for 7 years now.
GlassesOn app makes measuring very easy. Tried with 2 different phones couple times, and had same result every time. I ordered glasses with that measurement and it feels perfect
GlassesOn does a reasonable job, but it only measures binocular PD and uses the distance between the centre of the pupils. In most cases, this is sufficient for single vision lenses. For PALs however you need an accurate monocular PD that measures the distance between the visual axis. Often the visual axis is slightly medial to the centre of the pupil. A dedicated pupilometer will measure the corneal reflex light to determine this.
I always have this question: After you've received the glasses, how do you minor adjustment... like the nose pad, or even the arm so that it can be a perfect fit?
Right? They sit crooked on your face and need to be adjusted...how does that happen?
Most optical stores will do it. If they are nice, they will do it for free. Some businesses might charge a service fee. They will tell you since you did not buy from them, you are allowing them to service your glasses at your own risk.
It's always best to have them professionally adjusted. Most local places can help with this - sometimes for a small charge when it's a pair of glasses purchased elsewhere.
What a coincidence that I found this video.
I happened to want to try out online prescription glasses.
Our experience with the zenni eyeglass retailer has been a wise and cost-effective decision
I am also optometrists and tbh the online retailers are killing the business and increase more sales pressure on us.
What are your thoughts on the Apple Vision Pro as it relates to long term eye health?
Are these just polycarbonate lenses, if not which ones are they? I have found i see the best & most clear with Nikon lenses, they are 2nd to contact lenses which i can no longer wear bc of severe dry eye. How would Zenni lenses compare to Nikon lenses? Thx
Hello, Dr Allen. I have a very important question to ask you. I’ve just started to wear a spectacle with progressive lenses. The lenses are from Zeiss and they are phenomenal! But I also have a powered sunglass from my earlier prescription. This sunglass is a single-vision one (for my nearsightedness) and the lenses are from Essilor Xperio. The power of farsightedness in this sunglass is almost the same as the new progressive one. Can I wear these sunglasses when I go outside? Or will it harm my vision because now I have a progressive vision? Please advise.
Except they’ve never ever, ever have gotten the prescription correct…the index is always off, the PD is too narrow or wide…just impossible. I go in to the brick and mortar shops now after attempting on line orders 6 times at 3 different on line companies.
Thanks for sharing your experience!
Excellent instructional video! But I have to say that I am so tired of being "sold" on high index lenses. I order from an online eyeglass provider that thankfully allows me to order any of their lens options with my -9.50 prescription. Several years ago when I was low on cash (but high on diopters, LOL), I ordered their 1.56 index lenses in a progressive no less. I admit I was shocked that I couldn't tell the difference in my vision compared with 1.74 index lenses. No distortion (and boy how many times was I told there would be intolerable distortion), and no noticable weight increase (my secret was to order an 8g weight frame.) My latest online order was for 1.59 polycarbonate lenses and once again, they're completely fine, no issues, no complaints. It makes me sad to look back on years of paying as much as $800 for 1.74 high index lens progressives in frames from the "value line" frames from a local optician when my most recent order cost $77.85. And it makes me angry when I recall how many opticians and labs refused to make my lenses in anything less than 1.74 high index.
Sorry that you’ve had a bad experience in the past! Most people don’t notice a visual difference between lens materials, but some really do. I would say that high index lenses have as much to do with thickness and weight of the lens as they do with the clarity. Frame selection plays a huge role in the thickness and weight of the lenses, too. Generally, high index lenses for high prescriptions is going to provide a more comfortable and aesthetically pleasing experience for the wearer, and that is why I still recommend high index lenses (typically 1.60 or 1.67) for prescriptions at or above +/-4.00. That said, everyone is different and values different things, so I’m glad that polycarbonate has worked well for you!
Thank you for tips , it was really easy to order glasses )))) I paid express delivery $19 .. al total $75 , in the store the cheapest was $300 .... Do you guys feel the difference ?
How about a video for what is needed to order progressive lenses? This seems like the trickiest option. If not a video can your provide some details in a response to this message. Thanks.
Zenni, unfortunately, told me, "We are unable to produce prism for progressive or bifocal glasses". I've had to buy progressives with prisms from a store-based optician, at about three times the cost of what Zenni would probably have charged.
Just got some glasses today from my eye doctor. I had no idea about high index being important for strong prescriptions before. Both my eyes are about -7.00, and my last pair made me nauseous so I never wore them. They were pretty pricey but I got high index 1.67 lenses for these, so I hope that helps out!
How to order spectacles online
1. Pick up your phone, tablet or switch on your computer.
2. Book in for a sight test
3. Turn up to your eye test
4. Get dispensed with a decent pair of glasses by someone who is trained and knows what they are bloody doing.
5. Pay what you need to and wait 7 to 10 days (or 1 hour if your opticians has an on-site lab)
6. Pick up your glasses, have them adjusted to fit by someone who is trained, then bugger off.
The end
😄
And pay $800 for what costs $80 online. Life's full of choices, and sometimes "cheap" is the option you need. It'd be lovely if we all had the money to do this
When choosing frames I ALWAYS go in this order:
1. Prescription/use (finding a frame that fits the prescription and what you will use the glasses for).
2. Fit (selecting frames that fit your face and center your eyes well within the frame).
3. Style (things like shape of the frame, acetate vs metal, and color).
I’m pretty against the notion of picking frames by starting with trying to pick a frame shape according to some nebulous idea of face shape. Wear what you want, as long as it fits your face and prescription!
The PD is the biggest problem, as they don't include this in the prescription in the UK, and they are sheepish about giving it to you. I've measured it myself, but never sure if 1-2mm either way makes so much difference. having said that, the last local shop I went to didn't bother measuring the PD either - they were basically just operatives for an online site in the same way I could do myself (better) in the comfort of my own home...
Yeah I understand where clinics are coming from. They are frustrated because they are middled by glasses manufacturers and insurance companies - they get paid very little for their time and expertise and then people don't buy glasses and instead buy elsewhere. A lot of eye clinics are at risk of going out of business because of this or they will have to drastically change their business models.
With that being said, I understand why some clinics charge for the PD measurement (especially if they are using pupillometers which help measure PD with extreme accuracy) as they had to purchase that equipment and it isn't always cheap.
But in order to do a refraction properly, the phoropter (instrument people use to measure the glasses rx), needs to be set for the correct PD anyway. So it is very much part of the refraction procedure. The only challenge is that the phoropter only works in binocular PD - where some people require monocular PD for the most accuracy in their lenses.
For a progressive or varifocal, 2mm will definitely make a difference. I would be wary of anyone dispensing varifocals without measuring PD using either a corneal reflex pupilometer or a digital alternative like Zeiss Visufit.
For iPhone users, PD+ app measures seg heights also so try that.
Hi! I'm really hoping you can help me out with a question that I can't quite figure out. On my prescription my pupillary distance says 68/65. I'm not sure if that means I need to pick one to enter as a single number PD or if I have to enter both numbers as a double number PD. Sorry if my question wasn't worded in a way that's easy to understand. This is my first time purchasing glasses online and I'm absolutely clueless
Great question! Thank you. The first number is distance vision PD, the second number is near vision PD. (In case you were getting reading only glasses, or bifocals etc)
First time here. Very clear instructions! Looking forward to reducing insurance premiums 🙂
Thanks for being here! Glad you found the video helpful!
Just be sure to keep seeing your eye doctor for regular eye health checkups please!
What about vertical PD? My local place who gave me my full prescription including pupil distance, said it's ok buy online but never progressives because they cant measure the vertical location so it could be wildly inaccurate.
Thanks for watching!
If Zenni can do this so cheaply why cant my local eye clinic? Is it greed or what?
Lack of overhead (no brick and mortar stores to maintain)? Interesting question.
@@JMcYrk I'm sure that is part of it, but they are making at least 70 bucks a pop on exams too.
There is a lot to the economics of it. Of course the cost of overhead and paying local staff a living wage - that goes into the cost because the local shop has to make a profit. The quality of the materials and products they choose to sell plays a role as many local stores cannot even buy glasses from the vendors they use at a cost as low as some online opticals offer.
The other factor people don't see is the control of insurance companies. Many clinics offer "vision insurance" which is offered through companies who also...own the frame, lenses, etc. And those insurance contracts require the stores to give large discounts on their products to the people who carry the insurance. So because of these large discounts - they local store has to increase their prices dramatically because otherwise they would LOSE money on selling glasses. And it would be illegal to charge a higher price for some customers vs others. SO the price of the glasses have to go way up for EVERYONE.
And unfortunately, many insurance plans only reimburse the clinic/doctor about 35-40 dollars for their time in the exam room, which is why you see some doctors having to see a patient every 5-10 minutes (which I fear can drive poorer quality of care). That leaves the clinic in hope you would buy glasses from them to make up the difference.
Again, it can get complex. Perhaps a good video?
@@DoctorEyeHealth I think it would be a great video, I guess with all the challenges you have... Is the model working for you? I know this was a sponsored video and I don't want you to lose your sponsors but is a zenni experience inferior? I'm fortunate in that I can afford to pay more for better quality care, but lots can't and is online "good enough"
@@RobertKirkpatrick84 I don't mind the docs being reimbursed for their time, education, and expertise. My primary care doc charges $100 per visit, so $70 is not unreasonable (IMO).
Thank you for this video. I needed some cheap-o glasses to get me through the time between cataract and retinal surgeries. It was helpful to spend only $100 as opposed to the $600 I spend locally.
Hope things are going well with the surgeries!
Can you please do a video/review of the Renpho Eyeris Heated Eye Massager?? I would really love to know if it's safe to use and if it works! Thank you🥰
Thank you for making this video.
what color lens for sunglasses is best for bright sun?
General Grey lenses or Amber Lenses are the classic colors for which you will see most sunglasses made. There are also Pink/red lenses and Green. Mostly user preference and what you would be using them for the most.
I don't think the "face shape" tool is active, just the virtual try-on, but it doesn't tell you what your face shape is.
My head is awkwardly shaped and I've always had trouble finding classes as they are amost always too small even shopping larger sizes in person. I was gifted a pair that do actually fit, they are my favorite pair but I know they won't last forever so this will definitely be helpful as I know at least for now I don't have a prescription but sunglasses are very important with that UV protection ✌️
I have one from a few years ago, should be fine yes?
I keep seeing these magnetic Fram color changing glasses. I am intrigued but I don't know if I should bite the bullet or just be more secure with a good pair them maybe try a second pair out of pocket
Wow... Great info, nice video! The explanation is very easy to understand! Thank you for sharing about How to Order Prescription Glasses Online!
You are so welcome! Glad you found it helpful!
Hi Doctor, you said that most people choose their lenses set for distance with monofocal lens implants with cataract surgery. Why is that? Why not near? It seems like it would make sense to have them set for near since you need the near vision for so many things including PUTTING YOUR CONTACTS IN. So, can you tall me why distance is better? Thank you.
Good question! This came up with a patient of mine yesterday. Some people do in fact choose to have single vision monofocal implants put in that are set for near instead of distance. In my experience, this works better for people who have already been moderately nearsighted their whole lives. That way they have already been used to wearing glasses to see in the distance. The challenge is that some people who choose this, later regret the decision. Which is something that no doctor wants. So when someone is thinking of having that type of lens put in, we usually review it with them many many times and also have them sign a form that we discussed everything with them too.
@@DoctorEyeHealth I see. I am far sighted and I have an astigmatism. I have been wearing glasses my whole life. My glasses have been set to make me somewhat near sighted. This gave my eyes more rest at reduced the tendency to cross. I am considering lens replacement now. I am considering monofocal lenses and trying to decide on near versus far. I have strongly been considering monovision with one set for near, and the other set for medium (computer) distance.
I recommend pair eyewear they are very good and their glasses are magnetic so they make sunglass toppers that just stick onto them and the glasses are only 60$ and very high quality
Update : Just ordered my first online eyeglasses from Zenni, single version with mirror mid-index lenses
Not with my prescription 😢
Yeah it can be tough if you have a unique prescription. Hope all is well!
How long did it take for delivery?
Hi! Could you mention how to order prescription swim goggles and what data (sph/cyl/axis) needs to be taken into consideration as online websites just mention -4 to -1, Appreciate guidance. Thanks
We appreciate your willingness to instruct us
?I have frames I love, my optometrist won’t replace the lenses. Where can I get this done?
CNET has a good article on the best places to buy replacement lenses online. I just ordered from LensDirect, and will probably go with Lensabl for 1.74 high index Transitions in another frame.
Hey Dr, my question what Lenses would you think would be better for glaucoma patients and distance Thank you how would I you answer my .
hello sir i have this glasses prescriptions LE -2.50 -0.50 *10 and RE -2.50 -0.50 * 165 .How should i calculate it for best lens to buy ?
Excellent and thanks.
My left eye is very weak my script reads Cyl + 4.00 the right is +1.25 I was going to get the 1.67 Varilux comfort lens but it only goes to Cyl +3.00. What lenses should I get?
It's sad the cylinder only goes up to -6 and the Axis field does not allow you to enter 015 it's either 0 or 1.
Hey Dr.Allen! Do you have a video on which high index lenses you should be going with based on your individual prescription? Really enjoy your videos! Thanks!
Yeah we broke it down a little further in this video here: th-cam.com/video/k2dqcCIKQG4/w-d-xo.htmlsi=KI-x2sI_-fyQtKHg
No thoughts about the anti-fog option?
Hello Dr Allen, hope you read my comment and solve the problem that I have🙏🙏. I have a myopia of -1.50 in both eyes and don't have any other problems with my eyes, my cornea thickness, and pupil diameter everything is ok, so now I want to go for Femto LASIK surgery to have a vision of 20/20. I searched a lot there are different comments so now I am scared and I don't know what to do but still I want that surgery to correct my vision completely. If I go for this surgery is there any risk of glare or halos or any other permanent problem in the future? is it worth doing this surgery or I should be with this -150 myopia and wear glasses?
If U choose standard lens you are not getting the option to get for oil resistant lens and if you choose their premium it is way too expensive so this is not so good. I have to get transition and progressive and wanted to get everything but is is coming up way too much😢😢😢😢😢
I love the Transitions brand of lenses too but another option that may be more affordable would be Zenni's own photochromic lenses - they are not "Transitions" brand but may work similarly in that they will change to darker lenses in the sunlight.
@@DoctorEyeHealth thanks but the glare and the UV bothers me alot and this is my first time ever seeing th optometrist. Also he says one of my eyes is weak so it's alot😞
How do you measure for bifocals
does the prescription cover astigmatism too?
Dang, I'mma gonna watch this one. Have you saw any people's vision changed b/c of v injuries or covid? I was severely injured by v but recovering after 2.5 years. 500 hours in hbot, triple therapy, ivm, ldn, maraviroc, statins. I dread seeing him. Hard to get checkups w/out breaking down with all that.
Thank you so much for such informative video, I do have a question regarding glasses that "my prescription is -3 cyl with 180degree axis both eyes" I am having tough time in getting adjusted to powered lenses because of first time, getting blurred vision every time I move my head because of axis change. any tips and tricks for me to resolve or minimise such problems...
I get my glasses from Zenni, and they are better than the pair I got from my optometrist. And, MUCH CHEAPER!
Happy to hear they are working for you!
I have purchased online glasses here in Germany, so far the experience has been great. In fact, besides the normal glasses I have also purchased special use-case glasses specifically for watching TV at about 2 m (SPH values with +0.50 added,) for computer usage (for focusing at arm's length distance, so with +1.50 added to my SPH values), and for reading (with +2.50.) In all of this I never changed the PD values though, yet the glasses all work great for me. After reading another comment here, I do wonder if for reading glasses one should better adequately shorten the PD distances? From what I can tell taking selfies with a ruler on my face, my interpupilary distance goes from about 68 mm when looking into the distance to about only 58 when reading.
Technically speak, yes, reading only glasses should have a smaller PD which can be measured easily with a millimeter ruler. Otherwise local eye clinics can help measure for it too. Otherwise the prismatic effect of the glasses may contribute to eye strain.
@@DoctorEyeHealthThanks a lot! Then from the same reasoning, the computer distance glasses should then also have their own smaller PD? But somewhere between that of normal glasses vs. reading ones? Or it does not matter much for those?
@@DoctorEyeHealth Ok just saw an older video of yours that you listed in the description (how to measure your PD) where you indicate that for reading glasses typically the rule is to substract 3 mm from the total interpupilary distance, and this matches what one of the Zenni pages says. I am realizing the selfie measurement I listed above for reading PD was way too small because my cell phone was way closer to my face, while for the normal PD photo the cell phone was far and with zoom.
Thanks again!
So if I'm a -0.50 and i choose a higher index lens won't affect my glasses?
Can I add prescription lenses to a Ray ban frame that I bought online?
You would probably have to go into a store for that. Tell them you dropped your glasses over a sewer grate or something and just have the frames, and need new lenses.
I've used Zenni for years for my kids and myself. It's almost always been great! I ran into a problem when I switched to progressive lenses. Zenni couldn't get them right. So, I strongly recommend Zenni, but only for single vision lenses.
Perfectly and thoroughly explained. Great video.
Hey thank you! I appreciate that!
I know this ain't the video, but is it normal to have kind of blurry/shaky vision looking at things near you when using contacts for foresight issues?
If the contact lenses don't fit perfectly or they move on the eye, then seeing fluctuating vision is more common.
@@DoctorEyeHealth They are slightly bigger than the cornea. So I think they kinda gravitate towards my lower eye lids and I feel it...I don't think that's a problem though
I feel like frames never fit me. I have a fat face but a skinny nose and all frame manufacturers think if your face is wide you also have a giant nose. So I either end up witn frames falling off my face or pinching/not cute.
I really didn't think Zenni was that much more affordable than anyone else. I guess I was wrong.
It does depend on a lot of factors. Still, if you want better quality or extra features things will cost a bit more.
Do you have a website or somewhere that i can make you a question about contact lenses
Great video, great advice, perfect timing for me!
Glad it was helpful! Let me know if you have any questions!
I’m nearsighted (-0.5 in both eyes) with an astigmatism, my glasses are great for driving but for computer use my monitor is just far enough away that I want that astigmatism correction but when I wear my glasses it feels like it “focuses” my eyes further away than my monitor. Could I order a pair with a lower PD to “focus” my eyes to the screen? Similar to reading glasses even though I’d still want it to be a negative prescription?
Changing the PD of glasses can result in negative consequences to eyesight and comfort. It could even cause problems with the eye muscles leading to eyestrain and...depending on the person, could cause other issues with eye alignment and dominance perhaps.
If someone is having problems up close, such as staring at a computer monitor, it would be best to have an assessment by a doctor to prescribe computer glasses with the appropriate powers. Changing the PD alone would not be appropriate.
Hopefully the Dr. will answer, but I think you need to adjust mostly the SPH values (not sure about the PD.) Computer glasses focus at about arm's length or slightly less, that is somewhere in the range 20-28", or 50-70cm. To have the focus at that distance, you'd need to ADD about +1.50 (for up-closer laptop usage maybe better +1.75) to your SPH values on both eyes, still preserving the exact same values you might have for CYL and AXS (if you have any astigmatism.) Hopefully he will corroborate or rectify this.
How do you measure glasses or know what the best measurements are if your current pair don’t have the numbers printed on the side? Or if the numbers have worn off?
With a ruler. Or try some frames on locally and take note of the numbers. How do you know what size shoe you wear? How do you know what size clothes you wear?
I would love to order online but I have a narrow face, like a kid. There is just nothing online if I add the sizes. Even in kid's section. 47-18-140...😅 It's so fustrating.
Hi Dr. Allen,
Of course i do it.
As an EE, i measure my own refractive state.
This is how I went from 20/50 to 20/20.
I know you do not understand the science of objective prevention.
Zennioptical was essential to me.
What is an EE?
@@DoctorEyeHealth Hi Dr. Allen,
An EE is an Electrical Engineer, interested it the behavior of all eyes, with the goal of preventing entry into myopia.
Zenni's PD tool is definitely not FDA approved lol.
How are they with complicated prescriptions? I am highly nearsighted with a -6.75 Sph, and strong astigmatism 2.75 cyl, 180 axis. I also wear progressives.
In case you haven't got a response yet, you can set filters when searching for glasses that will fit your perscriptions.
U find out? We are similar. Bout to roll the dice, its only 30 bucks, just want some relief from contacts at home.
Any tips for glasses shapes for when your ears are at slightly different heights... my glasses always look/are crooked.
Get them adjusted professionally if you can. I have the same problem, and good fit adjustment is mandatory for me.
Something I think would've been nice to add was how accurate the prescriptions matched up to the lenses are in 2024!! I have an eye exam again this friday two years ago it was +4.25 in my left and a +5.25 in my right. I ordered a pair online two years ago, and they seem to be correct. I can get more for my money online but my biggest fear is I might have the wrong lenses and not noticed. Any thoughts?
I did a video a few years ago where I ordered glasses from about 6-7 different online vendors - there was some variability, but in my experience I had accurate lenses from Zenni (one of the reasons I worked with them on this video).You can always ask a local optical to check the accuracy - they may charge a small fee for this service but it would be one way to verify.
In addition to the powers being accurate, when you have a higher prescription the fit of the the glasses also becomes more important, so hopefully getting glasses adjusted would help too.
Walmart or Sam's club vision centers can check accuracy. I mention these for convenience bc they are a pretty common place where ppl go 😉
Almost my Rx! Not sure if you have ordered with progressive lenses online and if so, were you satisfied with them.
@brucesmith9144 I actually don't use progressive lenses I think mine are just considered reading glasses. I have ordered from zenni and glassesusa. Same prescription and I would say the zenni pair felt stronger? Only problem I had with them was the frames were to small for me. Glassesusa I got a pair of raybans and lenses for like $250. I can't speak for the exact accuracy on them either but I'm going to the eye doctor Friday and will ask them to see how correct they actually are. I will say though that my eye doctor seems willing to just upsale everything a single pair from there with just polycarbonate lenses with rayban frames was gonna be almost $400!! Currently looking at another pair from glassesusa with polychromatic lenses and 1.67 index with frames for $260.
Does anti-scratch coating do anything? I always get LOTS of fine scratching even with coating, and cleaning with the microfiber cloth. Any recommendations to care for plastic lenses?
I'd always wondered about how to shop for and where to look for online classes and you answered every question that I had and then some more, thank you so much for making this video!
I was stoked when you mentioned my glasses have the measurements on the inside of the arm. Then I looked and they've rubbed off 😆
Oh no!!!
If you know the model, you may be able to find the measurements. I've noticed not all glasses have them. If all else fails can try some on locally and take note of the sizes. Really wish online stores would let you demo the frames because sometimes a few mm larger or smaller makes a difference.
@BB-mt5no I appreciate it. I eventually just called the VA and got the info over the phone.
I have two different pupillary distance numbers, ad I'm not quite sure which one is for right eye and which one is for left eye. Need to be sure before filling an online prescription. Could you please help me about this?
There are 2 PDs. Distance & near. It is needed for bifocals & progressives.
No one can help you without measuring your eyes.
Is Smile surgery safe I am really done wearing glasses and or contactlenses?
It is considered very safe, but it is a newer procedure and best to find a qualified refractive surgeon with a good history of success with that procedure.
@@DoctorEyeHealth Ok great thank you for your answer
Been wearing glasses fir like 40 years. I've never heard of glasses that don't have nose pads.
Most of those Buddy Holly retro style frames don't have them i just got a new pair of Ray Bans and I prefer the no-pad design they have; those pads are a nightmare to clean and man, do they get dirty.
Thanks so much. Very informative. I've ordered from Zenni before, but prescription readers only. Your info will assist me when I order for prescriptives.
Hope it helps!
Does it matter with single vision +0,25 lenses to be off in PD in 1mm? I measured it myself, also my gf did it and went down with 62 mm. App says its 61mm but I have really dark eyes and it might be mistaken. But does 1mm in this case makes a huge difference?
I don’t think PD matters at all for single distance lenses.. it matters only for progressive lenses as you need to know what part of the lense you will be naturally looking through for distance.. the lense below that point gradually changing for close up vision
What is your thoughts on minor redundant conjunctiva?
Love Zenni glasses
Wow, they’ve come a long way.
Hello Doc. Joe! THANKS for this. Can you talk about the importance of P.D.? It seems SO important that many eye doctors who also sell glasses simply won't give your P.D. until you buy a pair of $800 plus glasses from them. My eyes are so bad I MUST have multiple pairs for driving and reading. I cannot afford $800 each for four to six pairs of glasses. I must buy glasses on-line instead. So, the last time I went to the eye doctor, I developed a trick. I watched the doctor's assistant, and she did not alter the machine she used to develop my prescription once she was done. I waited for her to leave the room after putting dilating drops in my eyes, and then I got out of the chair and took a photo of the machine's settings -- which had my P.D. displayed on her side of the machine -- turns out the P.D. of my eyes is different! It is SO unacceptable that an eye doctor will not give you your P.D. unless you get very angry with them and remind them of the LAW here in Connecticut. Even then, they will deflect and not give you the P.D.
Hi
Can i wear contact lens for 16 hours daily??
On my glasses the PD was way too small for me to read so I took a picture of it with my iPhone and then enlarged the picture. I've done the same for a lot of different items. I hope this will help someone else who is as challenged as I am by small print.
Also, I'm 71 and I got a pair of the glow in the dark glasses as well. You're never too old to have a little fun.😉
Perfect timing, thank you!
Hope it helps! Thanks for watching!
Great video! I've ordered glasses from Zenni a number of times with good results. You've touched on the key issues; in particular taking measurements from an older pair of glasses that fit well makes it a lot easier to choose the right size frame. If you wear progressive lenses, it's a good idea to get adjustable nose pieces in case the height of the frame needs to be tweaked to better position the reading portion of the lens. The oil resistant AR coating is definitely worth paying a little extra for. 👍👍
If I want progressive reader lenses, can I specify the prescription for the various areas of the lens?
Well the power of the progressives is based on the ADD of the lens written on the glasses prescription. The gradient or "power" in the different parts of the lens are based on the design of the progressive lens but is usually a gradual change - where the intermediate section is about 50% of the total ADD. Let me know if that makes senses or answers your question.
@@DoctorEyeHealth It does. Thank you.
Thank you for this so much! Ive been struggling to find simple help with simple questions filling out Rx online, so much that I was about to go on a full study myself and a video for other people, lol! Google was zero help. Cheers!
I order and they come on Thursday
Good God , are there any video guides that cut straight to the chase and tell you what you need to know in order to order online or are they all like this.
Thank you so much. Great 👍 information. I will use it soon.😊
Most welcome 😊 Hope it helps
Honestly, it was really good to know about the lens index. Yeah, I knew that it was thinner and lighter, which isn't a huge deal for me, but the biggest thing you mentioned was motion sickness. I have ZERO depth perception, which would require extremely thick prism to correct, so I just don't bother (I was born with a lazy eye, it got surgically corrected, but between that and patch therapy, never fully fixed the problem - although I do hear that VR training for both kids and adults is doing amazing things). If I'm in a vehicle for longer than an hour, I start getting sick. Faster if I don't eat, and even faster if I'm sitting in the back seat of a vehicle (city buses can be rough too depending on how much of a lead foot the driver has).
miss out plastic or metal frame
What about aspheric?
