When it comes to polarized sunglasses vs non polarized sunglasses, the biggest difference has to do with the polarized filter which blocks reflecting light coming from flat horizontal surfaces.
This significantly reduces glare and can even allow you to see deeper into bodies of water.
I personally find polarized lenses to be the best sunglasses for fishing and the best sunglasses for drinking. However, if you are a pilot or look at a digital screen outside, then the polarized lens may not be the best for you.
How to do a polarized sunglasses test:
Hold a pair of sunglasses in front of a computer screen, rotate the sunglasses while looking through the lenses and if the image of the computer screen goes black, the sunglasses are polarized.
You can also rotate one pair of polarized sunglasses against another pair of polarized lenses, if they go dark, then the lenses are polarized. If they do not, then at least one pair are non polarized sunglasses.

That was fantastic, really helped my understanding. Many thanks
need one under my welding helmet
Well done! As an airline pilot I learned that polarized lenses aren't approved for cockpit use, as you imply. Most cockpit windows and windshields are partially polarized during the curing process. Additionally, there's a list of sunglasses not approved for cockpit use since their color bias can obscure some flat screen indications. As you mentioned, polarized lenses are great for boating. Final take away from the aeromedical guys at ALPA (Airline Pilots' Association) is that cheap sunglasses can be worse than no sunglasses. Cheap glasses reduce the light and cause the pupil to dilate but they don't block harmful wavelengths, more harmful wavelengths strike the retina causing retinal damage and cataracts.
Excellent tips!!! Thanks for sharing all that! Yes, we learned about cheap sunglasses and that risk in school as well. However, I have yet to find a pair at the store that didn't have a label that said 100% or full UV light protection. Even the cheap ones, but I suppose they must be out there.
@@DoctorEyeHealth Not to sound sinical, but some large manufacturing companies fabricate products in unsafe ways and simply lie on the product description labels.
We C-130 pilots could not wear polarized sunglasses... Talk about a "colorful trip" when looking out of the cockpit.
You’d be surprised how many pilots wear polarized sunglasses. The window and avionics thing isn’t the real reason polarized isn’t recommended. It’s seeing the glare from other planes which is mostly eliminated by polarized sunglasses that’s the real issue here.
Cheers
I suggest you just stay in the house..
I wear polarized sunglasses only when dealing with people who have extreme polarized views and opinions.
Oddly enough, I've found those people often aren't that bright.
Hahahahha
😑
😂😂
Nice
Love polarized sunglasses. They are the bomb for driving in the snow when it is sunny.
Even in the rain
Great video! I used to wear polarized sunglasses while driving until I realized that they block the glare from ice on the roadway. In summer they are fine, but I no longer will wear them in winter.
Bruh
Thank you! Glad you found the video.
wait so if that happens how is it bad?
@@gaurav_W surprise ice is not a good thing
@@alexbretzlaff5461 but arent the roads black so isint there going to be enough contrast to know where the ice is anyway
I've always been light sensitive, and every pair of sunglasses I've had in 50 years have been polarized. Since LCD screens became common in automobiles, it has caused some problems; but I'd rather be able to see the road, than an entertainment center.
100% agreed.
Getting harder with the newer dashboards that are all LCD screens. Have to lift my glasses to see the speedometer, so thanks for cruise control.
@@markpashia7067 I think different screens will have different results. I have no problem seeing my digital dashboard and infotainment system when wearing polarized glasses. Phones too, iPhone screen won’t be much different but that’s not the case for galaxy phones.
That's cool
A good pair of polarized sunglasses totally knocks out a Heads Up Display because they operate on reflected light and reflected light is polarized.
My car has a heads up display on my wind shield in my car and noticed when I wear my polarized sunglasses the display is significantly dimmer... now I know why! Thank you!
Yes~ it seems that some different screens have their polarized filter oriented in different directions. My laptop is at an angle where my desktop screen is up and down. I don't know why lol
In the case of car HUDs, they often work by projecting the information from the top of the dash onto the windshield, which has an inner surface designed to reflect that projection back to the driver. Because it’s a reflection, it turns out to have the same orientation as the glare off of other cars and therefore will be blocked by polarized glasses.
I don’t think the auto manufacturers have much choice over that (unlike computer screens). If they did the projection from a different angle, it would be tough making reflect back at the driver or preventing distortion.
@@DoctorEyeHealth I heard a lot about the Serengeti Bi-Mirror Sedona lens, any input?
@@MrZog-yv3be yup true. should make polarized windshield instead.
Funny story about polarized sunglasses. I bought a polarized face shield for my motorcycle helmet. First time I road I almost fell off the bike in amazement. The polarizing filter in my glasses interacted with that of the face shield. Reflections off of asphalt at certain angles and some car window tints gave me a rainbow color effect like what I've heard is experienced by some on LSD. Really wild.
Yeah this was an issue for me. I specifically had to find non-polarized sunglasses for riding, which amazingly the best way I could find to get a non-polarized set of sunglasses was some really high end Ray Bans or Randolphs. It was somewhat tolerable for just seeing the road, but as soon as I was trying to see whether people in cars were looking/seeing me, I couldnt see ANYTHING between all the rainbow shimmering.
Polarized shields or glasses are actually unsafe to use when riding a motorcycle. The polarization will obscure slippery oil or water areas on the road. If you can't see the hazard, you won't be clued to avoid it.
@@pat8988 whoa, that's clever
When looking at plastic and glass through polarized lenses you can often see color patterns due to the stresses in the plastic. You can often see that in your carl’s back window. The thin plastic in the safety glass or the stresses in tempered glass will show up as colors. Polarized lenses are used to check for stress in transparent materials.
that's the G-15 green polarized lens ! they are SWEET
I prefer polarised sun glasses when I drive, because it cuts down the glare from the sun reflected from cars by eliminating or shrinking that glare, from a large spot to a small spot, making it easier to see. I learned more about the polarising filters with photography, where you get more clear, distinct colours when using these filters outside in bright sunlight. It does so by reducing the reflected light on subjects when photographing them. The polarising sun glasses do make it a little more difficult to read screens on my gps display. This is a very good explanation of how polarising works. Thanks!! (This program changes my Zs to Ss)
I have owned my ray-ban polarised glasses for a few years and love them. Driving, sailing, walking and cycling, they are superb. The best thing about these glasses is the true colour definition even in cloudy conditions. I let me wife try a few months ago when out walking on the beach in bright sun and she had on cheaper polarised glasses. The difference and clarity was amazing and so much I had to buy her a pair same as mine, green lens polarised ray-bans. These have to be the best on the market, true colour and great lenses. Ps I don’t work for the company, just used the product for many years and wouldn’t buy any other.
did you get laid after you bought her the glasses at least? 🤔
@@MAN9027 if not then 120 dollars wasted.
Not just the quality but the durability too. Ive owned a ton of cheap glasses and the ray bans were the first over $50.
5 years later, countless drops and things crushing them they still are in amazing condition.
Green Polarized is the best
You are absolutely correct. I have the blue lens polarized. Best purchase
Polarised prescription sunglasses are incredible. I'd been wearing prescription glasses for 18 years before I decided to get some polarised sunglasses and they've totally changed my experience with driving. They were incredibly worth it. 😎
This is good to know because I’ve been on the fence about buying a pair!
I’ve just purchased some polarised prescription Sunglasses , mainly for fishing, hopefully they will be helpful for driving.
@@stevenclarke5606 I went with Maui Jim's with a yellow tint. Love them...
@@davidunwin7868 ok thanks for the advice, I need to try them for driving
Great video on what polarization is. I would like to point out that I wear non-polarized, tinted sunglasses while I am driving because as regards to progressively darkening sunglasses, the filters that are built into car windows prevents the proper reaction of the glasses to the brightness. That is the only reason I wear tinted glasses rather than polarized in my car. However, using a polarizing filter on a camera is one of the most awe-inspiring things you can do. On a sunny day with white puffy clouds, polarizing filters will really increase the contrast in the clouds and darken the sky which makes for really really dramatic photographs. Finally, if you are taking photographs through a store window and there is glare on the window you can turn the polarizing filter on the camera until the glare is completely eliminated and all you see are the items beyond that window in the store. It’s almost like magic. Love your videos.
When I’m on the highway driving and it’s day light out but raining polarized lenses help a ton.
Fantastic video. Great info to finally understand something that we have basically taken for granted for so long without ever understanding the benefits. Sincere thanks. Your videos are extremely beneficial for the general public.
Great to hear! Thanks for your kind words Norm!
Doc, your comments and information regarding sunglasses and anything vision-related are top notch! I am an airline pilot, and sadly I cannot wear polarized sunglasses because of the reasons you so well expressed, but also because the glareshield of the aircraft is already polarized, so the light distortion through the sunglasses is uncomfortable and easily seen.
Watched a few videos trying to explain this concept, but this was definitely the best!! The real life examples really helps in understanding what you are talking about. Thank you so much!!
dr. allen, thanks for your sunglass videos. i am 47 and just had an eye exam. the doctor and his people were nice but advised me that it's in my best interest to start taking my eye health seriously. i work outside at a car plant moving cars for shipping. while i can read and see pretty good for my age, they did get me to buy near and far sighted glasses and showed me the difference between the eyeglasses and my current vision.
so as part of taking my eye health seriously, i ended up buying a pair of william painter level-model sunglasses. they have polarized lenses. compared to the garbage at sunglass hut and the monopoly that essilor-luxottica exerts on the market, WP was not cheap but def provided much more bang for the buck.
i spend a lot of time on the computer at home so i am getting blue blocker eye wear too.
where you intertwine with this is that i watched quite a few of your videos, and i am thankful for the education you provided. fair, honest and objective.
i will keep watching your videos so that i can learn more about eye health.
cheers from southern ontario 🍁
Very useful topic, trusting yourself and questioning everything is the very essence of being your own doctor, Thanks for being a mentor, i'm one of those who are very sensitive of light, due to suffering with keratoconjunctivitis for a long years.and i was not for Polarized glass, Now i know the difference.
Fantastic video with live demos and just to the point. Thank you for sharing😊
I love my polarized sunglasses. Helps me so much with my floaters. I even wear them when I am working on the computer. Love them.
Floaters?
This is a cool video!! My sunglasses are not polarized but I always like looking through my hubby’s polarized glasses when we’re fishing so I can see the fish better!
I have extreme sensitivity and was into walmart sunglasses through my early years. Until i was gifted a rayban polarized sunglasses, it was never the same. Polarized sunglasses is a must have for me and would yank any polarized sunglasses id ever encounter
I only ever buy polarized because I fish alot. Cool to see why they work. Also as a fun fact Air Traffic Controllers are not allowed to wear polarized either because of the window shades(rainbow affect)...at least that's what the FAA told me! Screens being blurred makes sense as well!
Your videos are so interesting and educational! So glad you have this channel 😊
Thank you for your fantastically simple to understand videos, I have just had surgery (detachment/cateract/Jag) for my right eye and now understand so much more about the options I have with lenses, which was not explained by the consultant or the optician. BTW I have allways had problems with bright lights (even more so since the surgery) so have started wearing polarised sunglasses. Great for driving etc BUT reading all the digital dials (inc the Head Up Display) in my BMW is now very hard! So I will have to think whether I compromise on being dazzled by the sunlight so I can see the readouts in the car.
I used to wear prescription glasses and I usually have a transition added to my lenses. When I bought my glasses from LensCrafters I noticed the polarization on my transition was a lot stronger than they were on non-prescription sunglasses like Ray-Ban‘s. For example looking at a manhole cover it completely dulled the glare from the sun but with non prescription sunglasses it dulled it but not completely
Sorry I'm not a native english, so I could not understand quite well, you meant that the LensCrafters or Ray-Ban were better?
@@gcpa7539 They mean that the LensCrafters were more polarized because they were prescription. They were better than the Ray-Ban's.
@@powderpink3063 thanks man
I've never been a fan of polarized lenses but this makes me want to rethink it in regards to certain applications. Thank you for an informative video!
Awesome video man! Your nerdyness is exactly what we all needed :)
I like polarised lenses. I'm getting my first pair of prescription sunglasses in the next week or so and I paid an extra $100 (AU) to get them polarised. I've worn polarised non-prescription sunglasses for a while and love how it reduces the reflections if it has been raining and the road is kind of shiny.
I hope you love your new sunglasses! What brand did you get?
Sounds like you got some ray ban polarized sunglasses.
I really enjoy your videos and have learned so much. I discovered that polarized sunglasses really helped me and now I have a better understanding of why. Thank you for sharing this very valuable information.
Glad you like them! Thanks Jean!
Very helpful video,tyvm!
First time I watch one of your videos, Amazing work keep going !
Thanks for your information. I found your channel a week ago, and it's been so useful for me.
Thanks a lot❤️
Great to hear! Thanks for watching. Please let me know if you have other questions or video topics you would like to see!
Maui Jim - that's my chosen brand for many years now, the world looks amazing thru them. Colors are bumped up like some live photoshop effect and I believe they have their own polarized technology
A very interesting and informative video. Thank you Dr.
Wow thank you so much, such a thorough explanation, very detailed too, I’ve learned something new today and I will be telling my friends about this too thank you 🙏🏽🙏🏽
I have migraines and polarized sunglasses just hurt my eyes and trigger my migraines. I tried multiple brands and still have the same dizziness feeling when wearing them so will just stick to the normal lenses (G-15 from Ray-Ban are just awesome for my eyes).
That's unfortunate. It helps wonders for me to prevent migraines on very sunny days. But I've heard it makes people dizzy before, I've heard people describe it as a "3D feeling" which kind of makes sense since polarized glasses are used in 3D theatres, each eye having a different polarization (vertical vs horizontal) so each eye only sees one of the 2 images.
There are two types of polarised filters. Linear and circular. The first one is older technology and required 2 lenses - you would turn them in different combination to receive required polarisation effect. The circular one is the type you had on the glasses you shown, yes by turning lens you can vary palarisation effect. I think circular technology is more practical, but linear gives you better control and stronger effect.
Awesome!! Thanks for clearing this out, now I know which one is best for me. Thanks again
I was searching for a pair of sunglasses today in lenskart and was puzzled by what was a polarized lens and a non-polarized lens. Decided to search it on google and then TH-cam for clarity, and your videos just popped it the moment I got into TH-cam without even searching. I got clarified with the polarization concept. Hey thanks, and I did make an informed decision about which lens to even buy. Polarized lenses are by far my fav as well. I travel a lot to & fro from college and henceforth you just saved my day. Hey, thanks again!!
I just canceled my lenskart order
I wear polarized prescription sunglasses when driving, cycling and most other outdoor things. I also have pair of non-polarized prescription sunglasses for times when polarized lenses are at a disadvantage like:
- when wearing a motorcycle helmet with a face shield as this produces some distorted effects
- when using a DSLR camera and using a polarized filter on the lens. Just like the computer screen example you could get your filter setting wrong.
Ah...I never thought about the motorcycle helmet
I love my polarized sunglasses when I'm driving especially. You forgot to mention that without them you see glare and reflections on your windshield from the dashboard and the polarized lenses eliminate them. You can see much clearer.
3:46 he does mention it
I plow snow in northern Canada . Polarized sunglasses really help add contrast and depth to what I'm looking at .
Very nice information. Thank you
And interestingly, this is exactly how watching 3D movies at the cinema works (your demonstration with the polarised lens in front of the computer screen was great). Two images are projected, one polarised in one direction and the other polarised in the other direction. The lenses then each block out one image, the left lens blocks out what the right eye wants to see and vice versa, creating the illusion that you've viewing a three dimensional object with your eyes, giving depth perception to an otherwise 2D image.
No it does not work that way anymore. The old 3D lenses worked that way, now you have circular polarization. en.wikipedia.org/wiki/Circular_polarization
The image does not blur when you tilt your head.
Very cool to learn how polarization works. I definitely noticed how if I drive my car without glasses the dash reflects on the windshield a LOT. but the moment I put on my glasses it almost entirely disappears so much so I have to focus on the reflection to know if it is there. Definitely makes sense now.
polish chap in Uk here - love your vids bro - appreciate you
Thank you for this informative video!
The example of turning the sunglasses was great. Reflection one way, and then gone.
Thanks! I have been trying to find ways to make the videos more visual, rather than just me talking lol
The clouds in the reflection of the car window was a cool example.
This was incredibly educational, helpful, and engaging. Thanks so much!
Hey I am really happy you liked it! I had fun making the video too. Please let me know if you have any other eye or glasses questions I can help with.
Finally this concept is clear to me. Thanks alot for the information 👍
Excellent presentation! Very informative.
Polarized sunglasses are a must when canoe tripping. Like fishing, it lets you see underwater and are able to avoid obstacles.
Polarized + gradient lens is literally my perfect driving sunglasses.
PS. can you a video explaining Oakley's Prism line of sunglasses? Thanks!
Sure thing! Thanks for the idea!
@@DoctorEyeHealth as someone who swears by oakly prizm lenzes (I work on the water as a deckhand) I would love to see this vid
I thought they can't gradient polarized lenses
@@calimon00 my wayfarers had a mild gradient to it. Very mild
Just got some sunglasses because of a minor stroke. Eyes are sensitive. You were very informative.
Its so timely , i am just about to buy a sunglass and this video guided me a lot. Thank you
This video is great! I always wanted to know if I wanted polarized or not because of the price I've not bought any but I will invest in a pair now. Thank you very much for all the visuals with polarized on and polarized off.
Thanks so much Fernando!! Glad you found it so helpful!!!
I can't go out without polarized sunglasses. Also started collecting them, the physics behind them is such simple and yet many people don't get it
Very nice vid, thanks!
Thank you so much for this informative video 👍🏼
Polarized sunglasses also wreak havoc in the viewfinder of many digital cameras, since many still use LCD displays. This doesn't happen if the display uses the newer OLED technology. As a photo buff, this is my biggest bane when shooting outdoors!
I just got my first pair of sunglasses within the last month and theyve been life changing. It's been a record breaking winter in my area. Lots of snow. Wet roads. It snowed pretty heavy overnight recently and it was sunny the next morning. Once I hit the road my eyes were burning and watering so bad I had to emergency stop at a CVS for SOMETHING. Picked up the only pair my BF thought looked good on me and now I have a second pair I got on Amazon. No more pain while driving😂
Great to hear! It has been a pretty crazy snow year here too. Thanks for sharing!
Wow, it's awesome knowledge.
Hats off to your efforts❤
Thank for your information ❤
Hahaha, glad to see I'm not the only person that bobs their head back and forth when wearing polarized lenses!
Sometimes you need to in order to judge the color of objects. I nearly failed my motorcycle riding class due to not being able to see the difference in color between the green and orange cones in certain orientations. It took me a bit of time to figure out what was going on.
I have two pairs-one polarised (for driving and general outdoors) and one non polarised for flying drones, because most phones and tablets have a similar problem as that you mentioned occurs in aircraft cabins.
especially in landscape mode.
My dad (rest his soul) would always talk about how polarized sunglasses was the shizzle (he didn’t say that though, since he was an elderly gentleman, but you get the gist). He wouldn’t tilt his head but show me the glasses and tilt ’em and I didn’t see any difference and just thought he was ”special”… Man, do I regret that now! This is the best thing I've ever seen when it comes to sunglasses! Now I get it! It is a big bonus that your eyes are blue as the sky on a sunny day, and I am officially in love with Doctor Eye Health. I am subscribing now!
super informative tenku!!
Polarized for me, Although have a tough time reading or seeing things like screens etc. outside with them, rest they're great!
I am the same way. I have a few non polarized ones which are nice, but I prefer the polarized ones.
Same for me. My Rx sunglasses are all polarized.
same for me
It really helps reduce reflective light that bounces off the dash from the sun on to the glass
Pretty cool explanation and demonstrations. Thank you 🙏🏼. I'm only a pilot of my truck and I fly it a lot for work and drive long distances all the time. I'm shopping for new sunglasses and I'm definitely getting polarized.
New to your channel, a video on photochromic would be greatly appreciated and how to possibly get the best photochromic glass. Also what are your favorite brands of eyewear.
That's a fantastic information. I am a photographer, I have Polarizing filters and I do use them to remove unwanted reflections from all kind of subjects 👌👌
Amazing!! The Physics behind polarisation is truly amazing!! The cancellation of two polarisation units is like cancellation of dipole moment in a non polar atom or molecule
wow, that's an amazing video that I've ever watched! Tons of information, clear-cut talk, and everything in between. Now I'm feeling like I'm heading to take a Ph.D. on sunglasses, lol.
THanks so much Rakib!!! Glad you liked it!
Welcome@@DoctorEyeHealth
Excellent info doc. I do fishing offshore a lot.
Perfect video just what I was curious about. Thanks Doc.
Hey thanks!!! That means a lot!
All the different brands that offer polarized lenses do have different quality to them. Some brands seem to have less distortion than others and some even make it difficult to see from my experience. Although I prefer non-polarized lenses, however there are a few situations where I feel having polarized lenses give you a huge advantage, mostly when outdoors in bright light and large bodies of water around you.
Thanks Andrew!
Polaroid has great polarization on relatively cheap sunglasses
Polarized for life. Don’t play with your eyes by cheaping out. I bought a pair of polarized prescription ray bans and it was expensive and stupid to pay the hefty price but I needed it because my eyes are sensitive to the sun.
Don't buy brands owns bye Luxottica. Its always cheep shit from china. if your going speed that much at least buy from Germany, Italy or japan made.
@@square5726 most ray bans are made in Italy like mines and are of amazing quality. I have a pair of Masunaga sunglasses which are made in japan out of titanium and are amazing quality but a bit pricey.
@@ChromeMan04 No it’s just assembled in Italy. Eye glasses brand own by Luxottica group and more has gotten away with that for years. Seeing according to Italian law. There are no limits on how much of a product must be made in Italy to earn the mark. Ask any honest opticians and they will back me up on this. When it comes to quality. Seeing it’s nothing wrong if’s it’s produced in China. Is just that you’re paying premium price for pare sunglasses frame. That’s made next to dose cheap Chinese sunglasses frame that people think are shit 😂. Also you right on buying prescription sunglasses. Dose give better protection from sun.
@@square5726 I know they are assembled in Italy but that still counts as made in Italy. I have a pair of Chinese sunglasses and they don’t compare to ray bans so I don’t believe this idea that luxxotica cheaps on their builds.
I am trying Eyenavision to add magnetics to my eyeglasses. They offer about 18 colors and 3 categories, Polarized is one of them. Much cheaper than Rx sunglasses.
Thanks so much valuable details ❤️
Thanks, it was very informative. I will now share this video. You deserve more likes. 👏😊
As I understand it, pilots are not supposed to use them because they block reflections. Those reflections are helpful to spot other air traffic in the distance. The gauges are an issue though.
Polarized sunglasses really help to keep from distracted driving too, since it makes screens unreadable!
Also, you're gorgeous. 🥺
But it also means that you can't use a gps, or atleast not use it without relying on the voice that's somehod always delayed
Awesome vid.
Many thanks 🙏🏻
Very informative, thanks a lot!!!
Definitely polarised, although we don’t have much need for sunglasses in Ireland! Has anyone told you you’re such a cool nerd?! "Nerd" is your word, I’d say "charmingly curious about the underlying nature of reality". ❤️🧿☘️🇮🇪😎
I live in North India. The sun just wont quit here. Take some from us please.
I just got DriveWear lenses (Polarized Transitions). They are awesome.

SUPERB VIDEO...U DID A LOT OF WORK..THANKS MAN.
When I was in photography school we did a few days leaning about polarized filters and saw a demonstration with a light box. It was so fascinating!
My teacher said when it comes to sunglasses polarized lenses will actually help you. Regular sunglasses are just colored plastic
I’m very light-sensitive and have migraines so I have to wear polarized.
Sometimes when I’m stuck in traffic I remember my photography class and turn my head from side to side to play with the lenses 🤣😂
Haha that is awesome! I didn't know about polarized lenses till I was in Opto school. They required us to even calculate the exact percent of light transmitted depending on the rotation of the polarized filter(s) against the incident light.
I should really sign up for a photography and videography class.
Great job, Doctor. I have a question. I suffer from chronic headaches and I had sunglasses . When I put it on, the pain was gone, but now it does not work for me. Can you find out the reason and do you recommend a certain type of sunglass?
Fantastic video, it realy helped me to choise the right one sunglasses. As the guy say, I had same problems from reflwcting light while driving, and that was a nightmare, I was exausted when I was driving all day whitout sunglasses or with nonpolarized cheap sunglasses. Now I bought quality polarized sunglasses and I don't have any problem while driving and I enjoy in it.
Thank you for the explanation! That helped a lot
Two guys in the desert.
Guy without polarized glasses: Hey I saw an oasis over there!
Guy with polarized glasses: No.
Hello Doctor Eye, congratulations for such excellent video!!! About what you mentioned in the end of the video if is it any difference between lens polarization brands, well I recently bought a ray ban justin classic ( blue classic polarized) and perceived that the polarized lens sun lights comes straight against me while I was driving. The sun light hits the car panel and the bright area become matte and blue in a pleasing way. An interesting thing is I can't see this effect in the store only when i drove and against the sun. I had other polarized sunglasses such oakley, nike, speedo, but never seen this effect before.
Effective against fog, also. Passed my glasses to friends in Halong Bay in Vietnam, we did see nearly perfectly through the fog. Impressive!
Very helpful. Thank you!
I had some issues with my vision getting bleary while driving a few years ago. This did not happen when riding my bicycle. The difference I realized, was that my driving glasses were polarized but the cycling glasses were just tinted. I suspect the underlying issue was that I had crossed eyes that were corrected with surgery when I was about 21. I'm sure the correction was not complete, but close enough for my brain to compensate for the remaining difference. As I got older, polarizing filters became a problem for my eyes. Got rid of the polarized lenses and have just bought tinted since. Maybe you have some experience with this or maybe it is something new to you? I'd be interested in hearing an optometrist's take on my experience.
I know this is old but did you learn anything new about this? I had eye correction surgery for a lazy eye when I was a kid and have not noticed issues with polarized lenses yet, but now I'm worried going into my 30s!
@@novinnovations4026 I have not learned anything new. I even had an eye checkup last year and mentioned it. It wasnt familiar to them, at least not the person who did my exam. I may inquire further at the next checkup. I was in my early to mid 50's when the polarized lenses became a problem.
I first discovered polarized sunglasses about the time I began driving in the early 1970's, and have been using them ever since. First pair I ever had were made by Polaroid (yes, the camera and film people). I've had so many over the years and have seen no difference in the amount or quality of polarization other than the color of the tint used. Some are tinted blue, or rose, or a gold/amber color. Rarely you can find a gray tint which is my preferred color because it's a neutral color.
I began wearing prescription glasses about 7 years ago. All the polarized "shades" I've used for years have been non-prescription simply because my vision is not bad enough to require me to wear prescriptions while driving. Recently I lost a pair of polarized shades, so for a change, I'm giving the polarized "clip-ons" over my regular prescriptions a try. They're available at Walgreen's and CVS locations, cost is just under $20. Probably at Walmart too, but who goes there? (I DO NOT!!) Tint color is rose or pink, or whatever you want to call it, definitely to the "red" side of the color spectrum.
A couple of things regarding polarization. The maximum amount of polarization occurs when the Sun is at a 90 degree angle from your direction of view. This is best seen when the Sun is high overhead during Summer months(May/June/July). Look at the blue sky in any direction and you'll see the maximum effect. Tilt your head, you'll see the change. As the angle of the Sun changes creating a change in the 90 degree angle, polarization changes. It changes substantially during the Winter months when the Sun is much lower in the sky, even at midday.
If you're driving into or away from the Sun (Sunrise or Sunset), that angle is either "0" or 180 degrees, which means there's very little to none polarization effect taking place. Also, there's no polarization at all when there is no Sunlight or in the night hours. And no effect under a Full Moon either.
Regarding screens on computers and LCD items, those will "black out" as demonstrated in this video, as will other things such as freshly paved asphalt. Polarized shades also help for bright Sunlight on snow or other bright surfaces. I once visited the Great Salt Desert in Utah. Needed them there too!!
Great explanation, thanks !
Awesome and Educational, I have learned so much from your channel..Thank you .🤗
