Hey Doc, this is off topic but I'd like to ask a question I'm curious about. Have you ever heard of, read about, or met anyone whose poor vision has blunted their emotional awareness? I ask this because I have astigmatism and keratoconus, so my vision has gotten to be a problem. It seems to me like my emotional awareness is low when I'm unable to see a person's eyes or facial expressions. I suppose it's common sense to assume that a low awareness (due to bad sight) of another's expressions (and expressive eyes) can diminish emotional connection in social situations, but I'm curious to know if there's any data or experience you have that correlates with that. Emotionally, I'm great, but I find it hard to express myself emotionally when I can't perceive the subtle emotional cues of another.
I'm getting different numbers but they're pretty close. Tried another app and got way less. Wtf? Zenni says I'm 58.5 (pretty sure that's wrong) this says 67-68.5. Tried zenni a couple times with different focus and they all came out 58.5 even when I crossed my eyes lol.
I thought that I remembered my PD from an eye exam being 67mm, but wasn't sure. Tried the app and it confirmed; spot-on, 67mm. Thanks for the app recommendation.
I've been getting my prescription after an eye exam for over 20 years. For the first time ever, the pd wasn't on my rx. I thought it was an oversight so I called the office to get it. He grudgingly gave it to me. I now know it's because he wanted me to order my glasses from their office. I'm going to try this app immediately.
@@senselessmonkee If it wasn't on the rx then they likely were hoping the person purchased the glasses in store. I find a lot of places don't hand out the rx unless specifically asked because they don't want to lose out on sales
Hey it actually worked really well! I measured 4 times: 68.0, 67.5, 68.0, 68.0 Didn't expect it to be this consistent and match the measurement of the optometrist.
I can’t get a doctor to give me my measurement if my life depended on it so this app is all I have to order my next pair of glasses online idk how it’s even legal to hold that info from someone 🤦♂️
@@bassproshophat8999it is a joke in the USA that doctors don’t give you the PD and most staff who sell you the frames are well sales people. I kinda laugh at how backwards the usa is Back home in Germany they use a device to measure the PD and done. Here at Henry Ford they seriously use a ruler
Because then if they told you everyone would get glasses online instead. 9 times out of 10 its always cheaper but on the flip side getting glasses from an optician will save you headaches literal and metaphorical in the long run. You pay for the care and knowledge in a lot of cases
Yea what Daniel said. A lot of places have tried to tell me that they don’t because they don’t want to be held liable if it’s not 100% correct. And without buying glasses at their store they cannot do it. Doesn’t sound legit right? Lol they just don’t want to go out of business

Hey thanks for app as it’s very useful. I finally know what my Pupillary Distance is even though my opticians have never told me for years. I didn’t know if them not telling you the PD was normal or not until now.
Very consistent. I was given 60.5 at lowest and 61.5 at the widest. I wouldn't blame the app for the inconsistency as my eye likes to drift with my slight strabismus. 61mm seems to be aligned with what I measure with a ruler in the mirror
This is a great app and super accurate. However, my daughter walked in on me doing it and said thanks for all the credit card info... dingus, and then walked out. Please everyone use an old card. He mentioned it once but worth repeating... cheers.
1mm lower from me manually measuring and I have a bias to round up to the larger number so I would give this app a thumbs up. Thank you Dr Eye Health for the hint!
I want to respond to this: 1. is there an app for monocular PD? 2. you are so right about seeing an eye doctor, especially if you have any chronic illness like diabetes. No website can identify macular degeneration, glaucoma or check your eye health. :) I love my eye doctor, he worked with me for 45 minutes to get me a prescription that fixes my double vision. Without those glasses, I'm sunk.
I just use vernier calipers. Held under my nose, to be closer to the depth of the eyes than something held on the forehead, reducing error. I have a quality set, but I've seen cheap plastic ones in dollar stores.
Thank you so much for letting us know about this app! Lighting does matter a lot though, when i did it indoors with not the greatest lighting i got, 61.5, 62, 63, 62.5 but with natural sun lighting outside the score were more accurate and i got 63,63, 63.5, 63.
Very cool app I wish I had come across this vid last week before I ordered glasses....Anyhow I notice this app gives a slightly different number depending how close you hold the phone to your face. Closer will give a little lower #, further a little higher. I measured my PD few times in different ways with a ruler in the mirror and seem to get a DP of 72mm, but a few times thought it may be more like 71.5mm. Just now I used the app a few times and got a range between 69.5mm when the phone was closest to 71.5mm when the phone was at arm's length. I would say to get the best reading you should go for arm's length and try to have the camera square to your face with the lens at eye level and centered between your eyes. Having the phone like that will give an image with the least distortion and thus best reading.
Excellent video. Here no one will give me my PD…I know they want me to get my glasses from them as a mark up. I’m “ok” with the business concept of this, but I want inserts for my VR headset which they don’t sell. I’ll def use this app
Hi Mr Eye Doctor, great video. Can you explain that although we measure pupil distance. How does the maker of the glasses account for the up and down centre because when watching this, i noticed that your eyes are well above centre of the actual lens withing your particular frames? many thanks
Nothing proving in large scale studies and largely not accepted in modern medicine, hopefully we will have some better studies one day where I could recommend something.
Thank you Sir, I have a question I am hypermetrop astigmat and my numbers are quite big, so should I use distance pd or near pd? and my second question is that in some optic centers the machine measures 62 mm and for some of them it is 64mm so do this machine measures my near or distance pd?
Hello dr 👁️ thanks for this video. I have had eye test after two years and they said the prescription changed slightly although I haven’t really noticed any change. I picked up new frames one for sunglasses and normal one. I noticed headaches and dizziness and my vision in new glasses is blurred so not as it should be taking that there stronger lenses. Went back to them thinking they will do another test with this new glasses, was only seen by the assistant and he asked me to look around the shop and asked how I see .. then took my glasses went away and said he’s manually adjust them. I asked about my PD and reluctantly he’s check it and admitted that he’s colleague got it wrong! Then asked if we are leaving them as they are or should they change my lenses!? I said change them if it’s wrong! Week later I collected them and I see no difference at all! I think they were not changed at all, and he’s just playing a placebo effect on me. I guess they would need to cover the cost from their own pocket hence it wasn’t done! I booked another eye test in different opticians up the road is more expensive however I want to have an independent result to compare and see if the prescription is correct in the first place and / or wrong PD. If I prove they’re at fault which most likely is the case I will request for a full refund for both pairs of glasses and the rest itself!
Hi sir, if you help I will be really happy. I am astigmat hipermetropic so I wear single vision glasses (aspheric) my PD is 64 mm total but do I need the pupilarity distance for both eyes separate like 33+31=64 or no need and what do they need to measure more
I've always wondered why they don't just include the PD on the prescription. I'm sure that at some point during my 20+ years of wearing glasses they've measured me. So just write it down....
I see that measurements are needed for the left and right pupils distances BUT if the frames are not centered exactly correct on the bridge of your nose because your nose is not symmetrical or your frames are off center slightly it will be off measurement anyway.
Just came across this and the app seems great EXCEPT for people who need a mono pd! Someone else asked you if there is an app to measure mono pd but I didn't see a reply...??? Would appreciate a reply to this....thanks!
It would help if the optometrists cold just measure the PD during your visit. They never do that anymore at a certain big chain store. They want the opticians to do it when you buy the super expensive in store frames, and even then, they really don't want to share that with you. The waited until after I paid for the pair of glasses before they printed something out with my mono PD. I hope that measurement will be correct for the rest of my life :)
first suggestion on youtube and the great advice! you totally saved me! I had the tape measure out and googling how to convert cm to mm, WAAAAY EASIER! #subbed

I had my last optometrist refuse to give me the number. I was livid. Measured it myself and got glasses on zenni optical for a fraction of the price ($56). I hate all things part of standard health “care”.
I recently went to for an exam and purchased an extra pair of glasses. I am near sighted and wound up getting bifocals because of my deteriorating night vision. Basically my first bifocal prescription. After receiving them, I was immediately upset. During my exam I told them (more than once) I spend most of my time in front of the computer screen and don't want to tilt my head back to see. Well, that's what I am doing. I have degenerative arthritis in my neck and spine. Very uncomfortable. I was insistent on making this point when I was there. Now, I have two pairs of bifocals I basically use for driving. I can't order a new pair unless I have an accurate pupil distance, which (I think on purpose) they didn't provide. Very frustrating after spending a fortune - even with insurance! I am going to give this app a try and hopefully avert another costly visit. Thanks.
Such a bummer to hear that Geo. I wonder if there was some miscommunication on their end. Oftentimes, if you are at the computer for a long time a dedicated prescription for computer glasses is ideal. I know some clinics don't always provide the PD on the script but most clinics will measure it for you if you ask, some clinics do charge for it as well.
@@DoctorEyeHealth As a followup: I tried to call them multiple times and received a recording about COVID, etc. They basically said the brick-and-motor store I went to doesn't exist. I went online and encountered a bot that was useless for my situation. I finally found an email and sent off my concerns. The only recourse is to physically go back to the store and demand some kind of refund or compensation to really get what I wanted in the first place. Thank you kindly for the reply. - Geo.
I have high myopia. My left eye is -8.25 myopic with -1.50 astigmatism. My right eye is -9.00 myopic with -0.75 astigmatism. I went to an optical shop today, and the worker used a special equipment to check my PD (pupillary distance). She said it is 58. My left eye is 28, and my right eye is 30. Should I use the "overall" PD when ordering glasses, or the two different eye-specific PDS when ordering glasses? I think she said that the two eye-specific PDS are usually only used when purchasing "progressive" lenses or "bifocal" lenses. I am not, I am only purchasing single distance lenses.
You only use "overall" PD if both eyes have the same pupillary distance. you have different PD's in each eye and therefore, you select two different eye-specific PDs when ordering glasses.
Thanks for your video. I also have 59 mm eye distance and I always find a hard time finding right glasses. I always end up seeing blurry at the edges on my glasses because doctors cant figure out the right distance based on the glasses dimensions.
Why is it so hard to get measurements from my optometrists. Not once have they ever used a pupilometer on me. I have to ask to get my binocular pd to get vr lens inserts, and my last dr. Just measured real quick using an old ruler. And just for my own knowledge I requested my monocular pd from the technician (if he was one) at the front desk and he gave me wrong information saying I can just divide my binocular pd by two. Not once have any optometrist office provided glasses that are custom for my face and pd, hence why I want the information so I can provide for myself and order elsewhere.
As in microphthalmia? There is no treatment specifically for the condition but there are important eye health issues that need to be managed. Best to see your local eye care professional.
Fantastic question Nino. There are many treatments for dry eyes and unfortunately it is difficult to tell what the BEST treatment is. It would depend on the type of dry eye you have and the severity of it. In general, dry eye is not considered a curable disease, some people may have dry eye symptoms, but when someone has dry eye disease then it is something that can be treated and managed but often not "cured"
I reccommend the app PD Meter Pro! You shouldn't look directly at the camera when you take the photo. You should look into the distance and take the picture. Your pupiliary distance decreases when you focus on closer objects. You can do a dual PD with many apps. Just pick the bridge of your nose for one point and the pupil of each eye with the second point. If you did it correctly. The dual PD should add up to the single PD. So, if your single PD is 66. Your monocular PD might be say 34/32 or 34+32=66. The monocular PD is typically written as 34/32. The first number is your right eye (OD "oculus dexter in Latin" of 34) and your left eye (OS "oculus sinister in Latin" of 32)
Doctor I wanted to know, I have compound myopic astigmatism and the pd my optician gave me was of my distant vision, So if I buy new glasses with that pupillary distance, Will it cause headache when I do near work as our eyes converge and our pd changes a little but our glasses pd remain the same?
For most people no. Thankfully our eye muscles adjust to this. However, for some people it can be troublesome and then they can get new glasses made for just computer use. That may ease eye strain.
I have to provide my PD to a VR company that will build the vr device to fit me specifically. I have progressive bigfocal glasses. It's a bit confusing on how best to do this vis a vis my type of glaases?
Thank you for this I was about to get progressive glasses online. I have my prescription but they didn't give me my PD. Now I realize I need something else....ugh
I've always wondered how the PD was measured. I do recall having it read by the eyeglass provider, but for some reason never by my optomitrist I asked her today (just had my annual eye exam) and was told they don't have the equipment needed, and that it's always done by the eyeglass provider. As a progressive lens wearer, I've always experienced the eyeglass provider technician using marker on the actual eyeglass lens, and have never felt comfortable with that technique, where they hold the pen while I have the glasses on and mark where my pupils are directly onto the lens. I'm not comfortable with that technique because I can see the pen "wavering" a bit before it marks the lens...how accurate can that be? Is there equipment that provides a more accurate measurement? I'd like to order my glasses from Warby Parker, and while their PD measurement app works well (it uses the same technique as this video), I'm now concerned that, because I wear progressives, I really should go to an eyeglass shop in person. Any advice you could provide?.
I've had glasses "fitted" with this pen on a plano lens technique - and I got eye strain as described, as they got one of my focal points off,and I'm a single vision wearer! :-( . That there is a machine that does it is very good - I wonder why prescribers don't use it!

Hi Mr Eye Doctor, great video. Can you explain that although we measure pupil distance. How does the maker of the glasses account for the up and down centre because when watching this, i noticed that your eyes are well above centre of the actual lens withing your particular frames? many thanks
I too had the same question!
Hey! Thanks for the video. Could you talk about weird/uncommon eye illnesses? I have oblicuos astigmatism so sadly I can't use daily lenses
Thanks a lot for the info on the Glasses on app , It made getting my PD some much easier.
Happy to help Robert!
@@DoctorEyeHealth PD - right eye 31, left eye 32
Sir this is my eye test report
is it ok ?
Does the eye exercise or not using glasses and try to see naturally reduce myopia
Nothing proving in large scale studies and largely not accepted in modern medicine, hopefully we will have some better studies one day where I could recommend something.
This is so true, I'm having hard time measuring my left and my right . They are different.
Thank you Sir, I have a question I am hypermetrop astigmat and my numbers are quite big, so should I use distance pd or near pd? and my second question is that in some optic centers the machine measures 62 mm and for some of them it is 64mm so do this machine measures my near or distance pd?
"A lot of eye diseases creep up on you." Yeah! I just discovered that I have glaucoma and that left untreated, I could go blind! Glad I went in! 😳
Does Night light, blue filter modes really protects the eyes
Yes, and he has videos addressing this topic.
Great question! Yes, there is a study that showed the blue light apps do help, not 100% but do help.
Hello dr 👁️ thanks for this video. I have had eye test after two years and they said the prescription changed slightly although I haven’t really noticed any change. I picked up new frames one for sunglasses and normal one. I noticed headaches and dizziness and my vision in new glasses is blurred so not as it should be taking that there stronger lenses. Went back to them thinking they will do another test with this new glasses, was only seen by the assistant and he asked me to look around the shop and asked how I see .. then took my glasses went away and said he’s manually adjust them. I asked about my PD and reluctantly he’s check it and admitted that he’s colleague got it wrong! Then asked if we are leaving them as they are or should they change my lenses!? I said change them if it’s wrong! Week later I collected them and I see no difference at all! I think they were not changed at all, and he’s just playing a placebo effect on me. I guess they would need to cover the cost from their own pocket hence it wasn’t done!
I booked another eye test in different opticians up the road is more expensive however I want to have an independent result to compare and see if the prescription is correct in the first place and / or wrong PD. If I prove they’re at fault which most likely is the case I will request for a full refund for both pairs of glasses and the rest itself!
Correct me if I am wrong but Progressive glasses are called varifocals in the UK
Multifocal in other parts of the world
Yes, that i only learned recently too!
Hi sir, if you help I will be really happy. I am astigmat hipermetropic so I wear single vision glasses (aspheric) my PD is 64 mm total but do I need the pupilarity distance for both eyes separate like 33+31=64 or no need and what do they need to measure more
I've always wondered why they don't just include the PD on the prescription. I'm sure that at some point during my 20+ years of wearing glasses they've measured me. So just write it down....
I tried it 3 times with 3 different results. 58.5, 58 and 59
Go with 58.5
@@jackmac919 why?
Ya
Its really confusing
That’s well within tolerance. An optician with a ruler can only guarantee +/- 1 mm, all measurements have uncertainty.
I see that measurements are needed for the left and right pupils distances BUT if the frames are not centered exactly correct on the bridge of your nose because your nose is not symmetrical or your frames are off center slightly it will be off measurement anyway.
Just came across this and the app seems great EXCEPT for people who need a mono pd! Someone else asked you if there is an app to measure mono pd but I didn't see a reply...??? Would appreciate a reply to this....thanks!
I want to download this app . But why this app is not available for my country
Thx for the info, I had to do it a couple times to make sure.
It would help if the optometrists cold just measure the PD during your visit. They never do that anymore at a certain big chain store. They want the opticians to do it when you buy the super expensive in store frames, and even then, they really don't want to share that with you. The waited until after I paid for the pair of glasses before they printed something out with my mono PD. I hope that measurement will be correct for the rest of my life :)
I always watch your videos without skipping ads.
online shopping for glasses is the best thing to have happened for people like us who need to see. Zenni optical is my go to.
Thanks for sharing! I have not tried zenni yet.
first suggestion on youtube and the great advice! you totally saved me! I had the tape measure out and googling how to convert cm to mm, WAAAAY EASIER! #subbed
Thank you so much for informing us of this app and then making a video for us!
Thanks for this info! Very helpful.. I just used the app to measure my PD.
Thanks! This is just what I needed!! ☮️💕🙏🏼
You are super awesome for sharing this! Thank you so much!!
Thank u so much, i was able to just place an order online.
Unfortunately this app appears to be incompatible with my device
Thank you for this video I was able to get my PD🙂
Does this work for us folks with a strabismus?
Probably not
Video suggestion - Could you talk about orthokeratology? I am thinking about getting into it but I m not completely sure if it's safe and what are the downsides
Overall it is a great option if you are a good candidate for it. I have the video on my list to do, just need to get some video/picture assets.
Is this measurement adequate for ordering bifocal glasses?
I have problem that is light ,led light uper on all leters pls
tv under subtitle mainly white in colour are shake on top pls tell anyone treatment but all are in long range only
GlassesOn app isn't available in Google Play Store anymore. Can anyone tell why? Thanks
I can't find the app in the UK do you have a suggestion for another app?
I had my last optometrist refuse to give me the number. I was livid. Measured it myself and got glasses on zenni optical for a fraction of the price ($56). I hate all things part of standard health “care”.
I recently went to for an exam and purchased an extra pair of glasses. I am near sighted and wound up getting bifocals because of my deteriorating night vision. Basically my first bifocal prescription. After receiving them, I was immediately upset. During my exam I told them (more than once) I spend most of my time in front of the computer screen and don't want to tilt my head back to see. Well, that's what I am doing. I have degenerative arthritis in my neck and spine. Very uncomfortable. I was insistent on making this point when I was there. Now, I have two pairs of bifocals I basically use for driving. I can't order a new pair unless I have an accurate pupil distance, which (I think on purpose) they didn't provide. Very frustrating after spending a fortune - even with insurance! I am going to give this app a try and hopefully avert another costly visit. Thanks.
Such a bummer to hear that Geo. I wonder if there was some miscommunication on their end. Oftentimes, if you are at the computer for a long time a dedicated prescription for computer glasses is ideal. I know some clinics don't always provide the PD on the script but most clinics will measure it for you if you ask, some clinics do charge for it as well.
@@DoctorEyeHealth As a followup: I tried to call them multiple times and received a recording about COVID, etc. They basically said the brick-and-motor store I went to doesn't exist. I went online and encountered a bot that was useless for my situation. I finally found an email and sent off my concerns. The only recourse is to physically go back to the store and demand some kind of refund or compensation to really get what I wanted in the first place. Thank you kindly for the reply. - Geo.
i downloaded the app, and used the PD feature 3 times and got 3 different results...67.5, 68.5, and 69.5!
There is some variability I noticed too, mine were all within 0.5 from each other. Perhaps taking several and then taking the avg?
I have something called blitheritis. My eye doctor does not care about helping me with this. What can I do to get rid of this? Dr.
He has a video on it. Its spelt blepharitis.
@@lalaithan Thank you.
hi, may i know why this app is not working here in UAE?
I have high myopia.
My left eye is -8.25 myopic with -1.50 astigmatism. My right eye is -9.00 myopic with -0.75 astigmatism.
I went to an optical shop today, and the worker used a special equipment to check my PD (pupillary distance). She said it is 58. My left eye is 28, and my right eye is 30.
Should I use the "overall" PD when ordering glasses, or the two different eye-specific PDS when ordering glasses?
I think she said that the two eye-specific PDS are usually only used when purchasing "progressive" lenses or "bifocal" lenses. I am not, I am only purchasing single distance lenses.
You only use "overall" PD if both eyes have the same pupillary distance. you have different PD's in each eye and therefore, you select two different eye-specific PDs when ordering glasses.
Not available in my country
I cannot access the app. The install button is not highlighted for me to download.
Thanks for your video. I also have 59 mm eye distance and I always find a hard time finding right glasses. I always end up seeing blurry at the edges on my glasses because doctors cant figure out the right distance based on the glasses dimensions.
Are you in a progressive?
No I have normal far distance glasses
OD = +2.00 Sph. +2.00 Cyl. * 095
OS = +2.00 Sph. +1.50 Cyl. * 075@@MommaLizard33
Why is it so hard to get measurements from my optometrists. Not once have they ever used a pupilometer on me. I have to ask to get my binocular pd to get vr lens inserts, and my last dr. Just measured real quick using an old ruler.
And just for my own knowledge I requested my monocular pd from the technician (if he was one) at the front desk and he gave me wrong information saying I can just divide my binocular pd by two.
Not once have any optometrist office provided glasses that are custom for my face and pd, hence why I want the information so I can provide for myself and order elsewhere.
Sir my one eye is small and one is large . Is any treatment available
As in microphthalmia? There is no treatment specifically for the condition but there are important eye health issues that need to be managed. Best to see your local eye care professional.
@@DoctorEyeHealth sir please recommend me any treatment
@@DoctorEyeHealth sir i am from Pakistan and there is not special doctors in our country. I want my treatment from world best doctor....
Can't find the app anywhere!???
This app does not seem to be available anymore...is there another suggestion?
Hi Dr I have a question I have dry eyes disease. And what is the best treatment for dry eyes?
Is dry eyes temporarily or permanently disease?
Fantastic question Nino. There are many treatments for dry eyes and unfortunately it is difficult to tell what the BEST treatment is. It would depend on the type of dry eye you have and the severity of it. In general, dry eye is not considered a curable disease, some people may have dry eye symptoms, but when someone has dry eye disease then it is something that can be treated and managed but often not "cured"
I reccommend the app PD Meter Pro! You shouldn't look directly at the camera when you take the photo. You should look into the distance and take the picture. Your pupiliary distance decreases when you focus on closer objects. You can do a dual PD with many apps. Just pick the bridge of your nose for one point and the pupil of each eye with the second point. If you did it correctly. The dual PD should add up to the single PD. So, if your single PD is 66. Your monocular PD might be say 34/32 or 34+32=66. The monocular PD is typically written as 34/32. The first number is your right eye (OD "oculus dexter in Latin" of 34) and your left eye (OS "oculus sinister in Latin" of 32)
Thank you kind Sir!
Thank you for this timely video! I am considering getting my first pair of eyeglasses online this year.
Hope it helps! who do you plan to purchase from?
@@DoctorEyeHealth I have no idea! Who is reputable?
@@lalaithan Your local optician!
@@JulienMarotte Thanks, but not what I asked. I've seen the same opthalmologist for the past 23 years, not gonna change now. 😂
Can you recommend face shield for with glasses
Oh my...I have only used ones provided to us at the clinic. So unfortunately I dont know of anything to recommend
While watching this video I just got an email saying that my new glasses (from online store) were in the post 🙂
Why do I feel like holding my card up to my camera is a scam trying to get my card number
It can be yes. It’s ok to be suspicious
Doctor I wanted to know, I have compound myopic astigmatism and the pd my optician gave me was of my distant vision, So if I buy new glasses with that pupillary distance, Will it cause headache when I do near work as our eyes converge and our pd changes a little but our glasses pd remain the same?
For most people no. Thankfully our eye muscles adjust to this. However, for some people it can be troublesome and then they can get new glasses made for just computer use. That may ease eye strain.
*Warning* i used this app and the result was 58 or 59mm then I went to optician to check and they measured it was 30/31
I have to provide my PD to a VR company that will build the vr device to fit me specifically. I have progressive bigfocal glasses. It's a bit confusing on how best to do this vis a vis my type of glaases?
How can I find my monocular pupillary distance on my own? Pls help! 🙏🏾
thank you. this was really helpful. will see how i get on with this
Thank you for this
I was about to get progressive glasses online. I have my prescription but they didn't give me my PD. Now I realize I need something else....ugh
Goddess! Doc! i used that app and i got different results and they are not even round numbers
I've always wondered how the PD was measured. I do recall having it read by the eyeglass provider, but for some reason never by my optomitrist I asked her today (just had my annual eye exam) and was told they don't have the equipment needed, and that it's always done by the eyeglass provider.
As a progressive lens wearer, I've always experienced the eyeglass provider technician using marker on the actual eyeglass lens, and have never felt comfortable with that technique, where they hold the pen while I have the glasses on and mark where my pupils are directly onto the lens. I'm not comfortable with that technique because I can see the pen "wavering" a bit before it marks the lens...how accurate can that be? Is there equipment that provides a more accurate measurement?
I'd like to order my glasses from Warby Parker, and while their PD measurement app works well (it uses the same technique as this video), I'm now concerned that, because I wear progressives, I really should go to an eyeglass shop in person.
Any advice you could provide?.
I've had glasses "fitted" with this pen on a plano lens technique - and I got eye strain as described, as they got one of my focal points off,and I'm a single vision wearer! :-( .
That there is a machine that does it is very good - I wonder why prescribers don't use it!
I got 67.5 mm for 4 consecutive time 😅
Thank you so much man!!!
