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'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.
@@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.
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.
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.
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 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!
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.
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.
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.
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.
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.
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.
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.
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". ❤️🧿☘️🇮🇪😎
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!
Optic neuritis can come from mulitple diseases/ conditions, Most commonly we associate it with Multiple Sclerosis. Optic neuritis is a type of swelling that huts the nerve and usually resolves on it's own, but unfortunately it can leave a person with permanent vision loss in some cases.
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.
That was an amzing guide, There's is a mojaor difference between the polarized and non polarized sunglasses, we personally have the polarized sunglasses for kids and recommend to all the parents to protect their children's eyes from harmful UV rays.
Great video. Question here - why are most polarized sunglasses lighter (tint wise) than regular sunglasses? Almost every pair of polarized shades I try on tend to have a lighter tint than the non polarized shades. I like the idea of not being able to see my eyes when I wear my shades outdoors.
Polarized glasses will absorb about half of the light that passes through them if they have no tint. This is because they absorb the horizontal component while leaving the vertical undisturbed. Humans do not actually experience brightness at a 1:1 ratio; we perceive brightness in an exponential manner. So if something blocks 50% of light we perceive it as 70% dimmer approximately. So a polarized lens wont appear that dim at all compared to other glasses unless there is something else absorbing or reflecting the light before it reaches your eye light tint or a mirrored finish.
It seems we could use a type of bifocal sunglasses with a non-polarized section at the bottom for looking at LED instruments in our dashboards when driving, cell phone screens, etc., and a polarized upper section for reducing glare.
I have issues with glare so I wear polarised sunglasses most of the time and have noticed digital kiosks and digital billboards will look blacked out so I can’t see anything on the screen. Also, bus, train and large building windows are polarised too and will look dark and distorted and hard to see through. I never understood why they did that before so, thank you for explaining it so concisely.
i wear polarized sunglasses when i go fishing too. sometimes, when the light hits just right and there is a slight ripple in the water, i can see a beautiful blue colour sparkling. it's almost pixelized.
I have a pair of prescription sunglasses and they are polarized. I went to buy gas, the display looked like a tie-dyed T-shirt. I learned something new. Good video.
I’m still amazed that it is impossible nowadays to get transmissibility vs wavelength for any sunglasses. This was readily available in the 90s and 2000s.
About the question "if have some difference among the polarized technology among the sunglasses brands" in my experience, I have a Ray-Ban Aviator G-15 polarized and Oakley Mainlink Prizm Black Polarized, and on the first look the Ray-Ban's back lens have some blue reflect or film, and Oakley's don't. However, oakley's dont make the rainbow effect on the phone, or some surfaces, but Ray-Ban's does
Never knew about that rotating "trick".. lol Just bought a new pair of photochromic polarized glasses from Serengeti. My old ones are just about 20 years old and i`ve got an upcoming fishingtrip to Italy next month :) Amber colored glasses are the way to go for fishing by the way, especially if you`re wading in rivers searching for trout. Keeps the details in the water nice and bright so you can clearly see where to put your feet. Thnx!!
Thanks for the polarization computer screen trick! Now I can seem interesting when company comes over. Btw, polarization is not recommended for mountain biking in general and when cycling at onset of and during dusk.
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.
I think it's a good idea to have both. I love my Ray Ban aviators. When I go for a walk I use the non polarized aviators. When I go out in the boat, I use my polarized aviators. This guy is so right about polarized glasses when having to look at computer screens. You have to drop them down to see the screen.
Polarized sunglasses are also a no go with some protective film. They use one in the train that create an impression of "oily reflection" if I wear polarized sunglasses. I make me nauseous. That one of the reason I always carry non-polarized sunglasses in my bag when I go to work.
I don’t know as much about the different glasses brands and what they claim but can’t say that there’s a huge difference in quality between good polarizing camera filter. The cheap ones cut out more light and introduced color casting. Like you said, some of that might be in the quality of the glass and other coatings besides polarization as well. I know that Maui Jim claims to have really good technology for their polarizing.
I prefer polarized. I have a huge sunglasses collection too, which include Ray-Ban, Randolph, Silhouette, Revo, Persol (9 pairs of 714's) etc. Probably going to sell them because I have to wear prescription sunglasses now. Bummer.
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 🙏🏽🙏🏽
Great video,,, there's a time I was in a mall and happened to walk by the TV section, and some of the screens were very dark, until I pulled up my sunglasses...didn't quite understand why, but now I know👍
Also if I'm not mistaken it can be considered a bit more healthy, since it "cuts off" a lot of the energy the natural light have. So less energy hitting your retina.
@@DoctorEyeHealth yeah I guess it also depends if less energy in itself would be healthy. But I mean way too intense one can be harmful, so my personal guess is less would be better, as long as it's enough. But I'm no specialist, I know more about the physical phenomenon (and even that is not my specialty 😅), not so much about the biological implications.
Late question here: Regarding the computer-screens. There are some "privacy" screens you can put on top of monitors so others can't see from the side, are those polarized so only the person straight ahead can see through because the light can't travel as good to the sides for the person standing there?
Yes there are different manufacturing methods. Most are laminated, and this process is greatly depends on the manufacturing plant quality control. I have seen Ray Bans delaminated. Oakley claims they used molding method or something which supposed to be superior to the laminating method.
Very helpful video. I'm planning to buy a pair of sunglasses for my father on his birthday. He has AMD so I think anything that will help him is good. This helped me understand the concept of polarized sunglasses. Thank you for the video
eye r truck driver Polarized lenses can be great for driving and if you're outdoors for long periods. There is potential to make it harder to see some display types, but quality polarization is not as bad with that as your $30 off the rack glasses. I'm still waiting for actual clear polarized lenses though. That's going to be huge for bad astigmatism on two lane roads in the rain.
I would say there is a big difference in polarization depending on the brand. Maji Jims are way better then O'Neal's. I think the price you pay for a premium pair is all worth it.
2:37, interestingly, my first polarized prescription glasses had the polarized filter oriented incorrectly: I saw everything in 3D, it felt like i could wrap my arms around a cloud. They had to redo the sunglasses. I would never go back to normal sunglasses: driving on a wet road, into the sun, or simply being at the beach looking at the sea are no longer an issue. Polarized lenses do cause 'blotches' in the windows of cars, but one soon gets used to it.
I notice with polarized lenses that when I look at the back window of another car I see the checker board hues within the window (kinda cool). Also I don't see the reflection of my dashboard on my windshield when driving.
Bought a pair of cheap $10 glasses from Walmart about a year ago and am finally getting around to looking for better ones! Any budget-friendly polarized 100% UV protection sunglasses brands you recommend? Love your channel! So glad I found it through your colored contacts videos!
Living in a sunny city like Las Vegas polarized is the best. I learned to buy high quality because low quality produces low clarity. Beware some designer brands as they can be low quality too. Loved my Fossils til I lost them, got Kate Spade where the clarity was blah.
I switched to non-polarised because I can't see the screen on my digital camera at all when wearing polarized sunglasses, and had to keep taking them off to take shots. I find *most* modern digital screens I can see with polarised lenses - my Garmin watch screen, my phone screen, the screen on my car computer - but the digital camera screen looked completely blank.
Ah I totally get that. Yeah as the screens have gotten so good I rarely use the standard viewfinder. Im not sure what tech they are using on phone screens and such but I agree, i dont see the polarized effect on them.
As a professional eyewear manufacturer, I'd like to share my perspective on polarized sunglasses. Firstly, polarized lenses are designed to meet the needs of specific scenarios, such as fishing, hiking, driving, and other outdoor activities. When wearing polarized sunglasses, we can better eliminate glare, allowing for clearer vision without being disturbed by reflections. However, there are certain driving situations where polarized lenses might not accurately render road conditions, potentially leading to misjudgments by the driver and incorrect reactions while driving. Nowadays, during long trips, many people rely on navigation systems. When wearing polarized lenses, it can be difficult to see the screen on a smartphone or in-car navigation system, which can be frustrating. Despite these issues, polarized lenses are generally very suitable for driving. However, there's a significant issue with the affordable polarized sunglasses on the market today: most polarized sunglasses under $80 typically use TAC (Triacetate Cellulose) polarized lenses. The advantage of TAC lenses is that they are inexpensive and lightweight, with manufacturers usually opting for 0.74mm or 1.1mm thicknesses. However, the primary material of TAC lenses tends to shrink and deform easily, and the polarized film is sandwiched between TAC layers using water-soluble glue. If the lenses are exposed to seawater or freshwater for an extended period, they can delaminate, rendering them unusable-a problem many consumers have likely encountered. Additionally, because TAC material is prone to shrinkage, manufacturers tend to cut the lenses larger, which can result in the lenses, particularly the 0.74mm thick ones, being severely compressed when fitted into frames. This compression can alter the optical performance of the lenses, causing the prism and diopter values to exceed industry standards significantly. This is why some people may feel dizzy when wearing polarized sunglasses-it's due to these distortions. Moreover, due to a lack of professionalism among some manufacturers, the polarization axis is not always properly aligned during the cutting process. If the polarization axis of the two lenses in a pair of sunglasses is not aligned correctly, it can reduce the effectiveness of the polarization and cause significant discomfort to the wearer. This issue is often found in cheaper polarized sunglasses. On the other hand, materials like CR39, nylon, or glass have much better optical performance compared to TAC lenses, which is why designer brands never use TAC. If polarized lenses are needed, they typically use CR39, nylon, or glass polarized lenses. There's also PC (polycarbonate) polarized lenses, though these are generally used in sports eyewear. Due to cost considerations, most polarized sunglasses under $80 opt for TAC lenses. If you’re considering polarized sunglasses under $40, I recommend avoiding them because the quality of TAC lenses in this price range often comes with many issues from production. So, if you're looking for daily wear and are more focused on fashion and sun protection, non-polarized sunglasses are an excellent choice. However, if you need sunglasses for functional purposes such as fishing or hiking, I recommend choosing polarized sunglasses.
THIS IS SO AMAZING! Thank you so much for sharing your knowledge and industry insight! I have wanted to know this info for so long!!! I just saved this comment in my notes. Thanks again!
FYI: Polorized lenses won’t work in luxury cars with “heads up displays”. This is also the case with other modern tech where reflection is a necessity.
Got polarized sun glasses with prescription around 8 years ago...I will never buy anything else. Just looking at trees, the sky, everything has so much more texture. Everything is more beautiful.
I go fishing a lot. And no one ever told me about polarized sunglasses until recently. I just thought sunglasses were sunglasses. They are game changing for fishing.
I wear Serengeti Carrara photochromic/ Polarised sunglasses, no issues with phones in landscape here, previous Raybans etc all blanked out the screen. These do not. Their optics are brilliant.
I remember entering white castle off the Vega strip with my polarized glasses and spent like 5 minutes inside trying to find the menu. Well white castle has their menu on big screen tvs and with polarized glasses they appeared like black screens until my kids told me to take off my glasses and bold and behold the menu was visible. 🤷🏻♂️ Learned something new.
I personally really like how things look while wearing polarized lens. Although I fish far far less than I did as a teen it's still really handy to have my sunglasses be polarized lens not requiring me to own more than one pair.
Personally I don’t like to drive in my polarized sunglasses because of all objects that are in shade are just too dark in the bright scene. That’s maybe is because of the filter which is too agressive.

I prefer polarized. I have a huge sunglasses collection too, which include Ray-Ban, Randolph, Silhouette, Revo, Persol (9 pairs of 714's) etc. Probably going to sell them because I have to wear prescription sunglasses now. Bummer.
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 🙏🏽🙏🏽
Great video,,, there's a time I was in a mall and happened to walk by the TV section, and some of the screens were very dark, until I pulled up my sunglasses...didn't quite understand why, but now I know👍
Exactly!
Also if I'm not mistaken it can be considered a bit more healthy, since it "cuts off" a lot of the energy the natural light have. So less energy hitting your retina.
I suppose it could be, there are a lot of theories about reducing oxidative stress to the retina.
@@DoctorEyeHealth yeah I guess it also depends if less energy in itself would be healthy. But I mean way too intense one can be harmful, so my personal guess is less would be better, as long as it's enough.
But I'm no specialist, I know more about the physical phenomenon (and even that is not my specialty 😅), not so much about the biological implications.
Thank you for such explicit explanations ❤🙏
appreciate your production effort. great work
Much appreciated! Thank you!
Simply awesome. Informative & interesting sharing session has made these issues very clear. You are great. Enjoyed the entire program. Manythanks.
very good explanation, but it could be even better regarding computer screens, laptops etc
Fantastic video with live demos and just to the point. Thank you for sharing😊
Wow! I have two pairs of Ray Bans and one has the P and the other doesn't. I was curious. Thanks. This was quite informative. Cheers dude!
Late question here: Regarding the computer-screens. There are some "privacy" screens you can put on top of monitors so others can't see from the side, are those polarized so only the person straight ahead can see through because the light can't travel as good to the sides for the person standing there?
Thats a good question. I don't think so. I think they use a type of prism. But I will look more into it.
just bought polarized Ray ban titanium model $650. loving it ♥️
Yes there are different manufacturing methods. Most are laminated, and this process is greatly depends on the manufacturing plant quality control. I have seen Ray Bans delaminated. Oakley claims they used molding method or something which supposed to be superior to the laminating method.
Very helpful video. I'm planning to buy a pair of sunglasses for my father on his birthday. He has AMD so I think anything that will help him is good. This helped me understand the concept of polarized sunglasses. Thank you for the video

Polarized lenses can be great for driving and if you're outdoors for long periods. There is potential to make it harder to see some display types, but quality polarization is not as bad with that as your $30 off the rack glasses.
I'm still waiting for actual clear polarized lenses though. That's going to be huge for bad astigmatism on two lane roads in the rain.
I would say there is a big difference in polarization depending on the brand. Maji Jims are way better then O'Neal's. I think the price you pay for a premium pair is all worth it.
2:37, interestingly, my first polarized prescription glasses had the polarized filter oriented incorrectly: I saw everything in 3D, it felt like i could wrap my arms around a cloud. They had to redo the sunglasses. I would never go back to normal sunglasses: driving on a wet road, into the sun, or simply being at the beach looking at the sea are no longer an issue. Polarized lenses do cause 'blotches' in the windows of cars, but one soon gets used to it.
Some car dashboards are polarized. This makes them look very dark when viewed through polarized glasses.
I notice with polarized lenses that when I look at the back window of another car I see the checker board hues within the window (kinda cool). Also I don't see the reflection of my dashboard on my windshield when driving.
Bought a pair of cheap $10 glasses from Walmart about a year ago and am finally getting around to looking for better ones! Any budget-friendly polarized 100% UV protection sunglasses brands you recommend? Love your channel! So glad I found it through your colored contacts videos!
Living in a sunny city like Las Vegas polarized is the best. I learned to buy high quality because low quality produces low clarity. Beware some designer brands as they can be low quality too. Loved my Fossils til I lost them, got Kate Spade where the clarity was blah.
Thanks for sharing! Other than Fossil, have you had any success with other brands?
I switched to non-polarised because I can't see the screen on my digital camera at all when wearing polarized sunglasses, and had to keep taking them off to take shots.
I find *most* modern digital screens I can see with polarised lenses - my Garmin watch screen, my phone screen, the screen on my car computer - but the digital camera screen looked completely blank.
Ah I totally get that. Yeah as the screens have gotten so good I rarely use the standard viewfinder. Im not sure what tech they are using on phone screens and such but I agree, i dont see the polarized effect on them.
As a professional eyewear manufacturer, I'd like to share my perspective on polarized sunglasses. Firstly, polarized lenses are designed to meet the needs of specific scenarios, such as fishing, hiking, driving, and other outdoor activities. When wearing polarized sunglasses, we can better eliminate glare, allowing for clearer vision without being disturbed by reflections. However, there are certain driving situations where polarized lenses might not accurately render road conditions, potentially leading to misjudgments by the driver and incorrect reactions while driving.
Nowadays, during long trips, many people rely on navigation systems. When wearing polarized lenses, it can be difficult to see the screen on a smartphone or in-car navigation system, which can be frustrating. Despite these issues, polarized lenses are generally very suitable for driving. However, there's a significant issue with the affordable polarized sunglasses on the market today: most polarized sunglasses under $80 typically use TAC (Triacetate Cellulose) polarized lenses. The advantage of TAC lenses is that they are inexpensive and lightweight, with manufacturers usually opting for 0.74mm or 1.1mm thicknesses.
However, the primary material of TAC lenses tends to shrink and deform easily, and the polarized film is sandwiched between TAC layers using water-soluble glue. If the lenses are exposed to seawater or freshwater for an extended period, they can delaminate, rendering them unusable-a problem many consumers have likely encountered. Additionally, because TAC material is prone to shrinkage, manufacturers tend to cut the lenses larger, which can result in the lenses, particularly the 0.74mm thick ones, being severely compressed when fitted into frames. This compression can alter the optical performance of the lenses, causing the prism and diopter values to exceed industry standards significantly. This is why some people may feel dizzy when wearing polarized sunglasses-it's due to these distortions.
Moreover, due to a lack of professionalism among some manufacturers, the polarization axis is not always properly aligned during the cutting process. If the polarization axis of the two lenses in a pair of sunglasses is not aligned correctly, it can reduce the effectiveness of the polarization and cause significant discomfort to the wearer. This issue is often found in cheaper polarized sunglasses.
On the other hand, materials like CR39, nylon, or glass have much better optical performance compared to TAC lenses, which is why designer brands never use TAC. If polarized lenses are needed, they typically use CR39, nylon, or glass polarized lenses. There's also PC (polycarbonate) polarized lenses, though these are generally used in sports eyewear. Due to cost considerations, most polarized sunglasses under $80 opt for TAC lenses. If you’re considering polarized sunglasses under $40, I recommend avoiding them because the quality of TAC lenses in this price range often comes with many issues from production.
So, if you're looking for daily wear and are more focused on fashion and sun protection, non-polarized sunglasses are an excellent choice. However, if you need sunglasses for functional purposes such as fishing or hiking, I recommend choosing polarized sunglasses.
THIS IS SO AMAZING! Thank you so much for sharing your knowledge and industry insight! I have wanted to know this info for so long!!!
I just saved this comment in my notes.
Thanks again!
What would be your opinion about polarized glasses with regard to mountain biking?
Check out heads up displays. Polarized glasses kept me from seeing the hud in both my corvette and cadillac…
Yeah it seems to be inconsistent between manufacturers, sometimes the displays are visible and some are not
I learned early on that polarized glasses render the heads up display in my car useless since the display is reflected off the windshield.
love your channel
Thank you! Glad you like it!
Yes please find that out and make a video about how different brands' polarization is?
FYI: Polorized lenses won’t work in luxury cars with “heads up displays”. This is also the case with other modern tech where reflection is a necessity.
Got polarized sun glasses with prescription around 8 years ago...I will never buy anything else. Just looking at trees, the sky, everything has so much more texture. Everything is more beautiful.
Polarized = Good
Not polarized = Bad
I know a lot about photographing and I never knew this wizardry before. Thanks.
I am still such a beginner when it comes to photography and videography...but I am learning to enjoy it, although frustrating at times.
Please do a video comparing when to use polarized sunglasses vs FL-41 lenses.
I go fishing a lot. And no one ever told me about polarized sunglasses until recently.
I just thought sunglasses were sunglasses.
They are game changing for fishing.
06:15 Glinda and Elphaba are HYPED ✨
I’ll wait for 2030 version of Transition Lenses 🤪😅✌🏾
Awesome video Doc 👌🏾😊👏🏽
*Tilts your head*
People be like "Woaah , he's the Terminator"
I wear Serengeti Carrara photochromic/ Polarised sunglasses, no issues with phones in landscape here, previous Raybans etc all blanked out the screen. These do not. Their optics are brilliant.
I just use my daughters sunglasses just for walking they always purchased new sunglasses every time they go on holiday
Thank you so much sir
That really helped me a lot to make my decision which sunglasses suits me the most.
I remember entering white castle off the Vega strip with my polarized glasses and spent like 5 minutes inside trying to find the menu. Well white castle has their menu on big screen tvs and with polarized glasses they appeared like black screens until my kids told me to take off my glasses and bold and behold the menu was visible. 🤷🏻♂️ Learned something new.
Maui Jim have a unique polarisation according to their marketing 🤷♂️
Regardless, their lens are amazing
Thanks so much valuable details ❤️
I’m buying some Ray Bans soon and I have to see whether it’s worth the extra $50. Thank you!!
What do you think of the RB2132?
Had to look the model up. But those are a great lens. I like the G-15 lenses myself. probably the best quality Rayban makes.
Did you decide on the lens for the Ray-Ban?
I personally really like how things look while wearing polarized lens. Although I fish far far less than I did as a teen it's still really handy to have my sunglasses be polarized lens not requiring me to own more than one pair.
Awesome!! Thanks for clearing this out, now I know which one is best for me. Thanks again
Personally I don’t like to drive in my polarized sunglasses because of all objects that are in shade are just too dark in the bright scene. That’s maybe is because of the filter which is too agressive.
That may greatly depend on the sunglasses and the strength of the lens (the density of the sunglasses tint)
Randolf polarized glasses are the best, Ive tried most brands
I agree!!! I love Randolf.
