Polarized VS Non Polarized Sunglasses

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.

I never realized how glaring the sun is until I got my first pair😂... I took mine off and I felt like I was getting blinded by the sun...Such a big difference

As a E&A lifegaurd at a Waterpark it is part of our license to have Polarised sunglasses since we are a outdoor facility and especially on our Wave Pool it is a must.

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. 😎

I wear polarized sunglasses only when dealing with people who have extreme polarized views and opinions.

Love polarized sunglasses. They are the bomb for driving in the snow when it is sunny.

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.

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.

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.

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 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

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.

🔴 Have you ever experienced polarized sunglasses before? Have you ever noticed if one brand works better than another? (seriously, want to know)

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.

I wear original wayfarer polarized sunglasses, and the polarization combined with the paniscopic tilt is perfect for boating/fishing on really sunny days. Awesome for driving, too.

When I’m on the highway driving and it’s day light out but raining polarized lenses help a ton.

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!

I am visually impaired and very sensitive to light. I wear an orange tint lens day and night but I have just ordered some sunglasses and the optician advised me to get polarised lenses. I did explain my problems with glare etc and after watching this I think they will be beneficial to me 👍

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😂
