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 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)
@howardlevinger45712 жыл бұрын
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.

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.

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.

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.

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.

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 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.

Pretty interesting fact : Many of Oakley’s performance lenses (Prizm trail and road) are not polarized because they think keeping the glare can be beneficial in a performance situation. I’m not sure why, maybe for helping you see puddles easily as you are going fast on a trail or road and avoid them (?).

I don't know if its been mentioned in the comments but in the early days of cinema they used two polarized filters in front of the lens to do the fade in and fade-outs. Question: I'm an ex-pro photographer and I always used polarised filters on my 35mm SLR cameras. Because the internal flipping mirrors were usually polarised (on high-end stuff like Nikon, Canon or Olympus) you had to make sure you used a circular polarising filter on the end of the lens otherwise it did weird things in the viewfinder like blacking out half the screen, presumably because the mirror was polarized with one half of the polarization going at 90º to the other. By circular polarization filter I mean the polarization was in a circular pattern rather than straight lines, not that the filter was physically circular (although it was as you have to screw it on the end of the lens). It struck me that if aircraft or car manufacturers agreed a particular angle of polarization for the glass at the front of their instruments, then the standard polarization of sunglasses (I'm guessing horizontal) could affect it the least, making instruments visible while wearing them. It might take a specialized method of application to get it perfectly right but I imagine the pilots/drivers eyes would gain a lot in glare reduction?

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.

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.

6:01 This is why I don't like polarized. Screws up looking at my phone in landscape mode. If I had my way, I'd have custom sunglasses made using a base of 15% to 50% VLT infrared-ceramic window tint, with flip-down polarizers. Probably the 50% or 35% since those are usually enough of a reduction that my eyes are comfortable without being "dark," Plus once you add the polarizer, the contrast goes up and it "feels" darker without actually being darker.

One thing I don't like about polarized sunglasses is that they block out the heads-up display in my car. That was an option I paid for! Also, you skimmed over the fact that a lens polarizer is NOT the same as eyewear. You might have a linear or a circular polarizer and the effects are different.

Polarized glasses are an excellent choice for cyclists and motorcyclists, as it greatly reduces the glare on windshields, making it much easier to see the driver inside, and therefore where their gaze is directed. Do they see you? Are they distracted? It's much easier to tell with polarized lenses. I feel much safer commuting on my bike in traffic with polarized lenses.

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 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!!
