Polarized lenses block sunlight as light reflected from surfaces such as a flat road or smooth water generally is horizontally polarized. This means that, instead of light being scattered in all directions in more usual ways, reflected light generally travels in a more horizontally oriented direction. This creates an annoying and sometimes dangerous intensity of light that we experience as glare.

What is the difference between UV protected lenses and polarized?
UV lens coatings are designed to block UV rays from reaching your eyes. Polarized lenses block glare (light reflected off of water or snow, for example) and improve vision that way. Polarized lenses do not offer UV protection - they would need to have a UV coating applied.
If you're driving towards the sun late in the afternoon you can reduce the glare from the road by wearing sunglasses that permit only the passage of light that's?
You can reduce the glare from the road by wearing sunglasses that permit only the passage of light that is polarized in a vertical plane. Polarized lenses, if correctly positioned, can block all reflected light from horizontal surfaces such as roads. Non-polarized sunglasses simply reduce the amount of light passing through, but some glare from reflected light remains.
How do polarizing sunglasses work?
Sunglasses work by placing pieces of tinted plastic polymer in front of your eyes. Light at all frequencies (from Infrared, visual, and Ultraviolet) coming from the sun hits the lenses and they act as a filter absorbing certain frequencies in certain amounts and allowing others to pass through. "gray" sunglasses are neutral and thus absorb all frequencies of visual light in equal amounts where as "rose tinted" glasses absorb more of the frequenceies that make up green, blue, indigo, and violet, and allow mostly red, orange and yellow to pass through. This can distort your perception of color outside the glasses so I don't recommend any colored glasses be it pink, brown, green are anything else. It's a misconception that only polarized lenses can block Ultraviolet light however it is true that usually cheap glasses do not. Even if they say "block 100% of UV rays" you may want to ask if it blocks 100% of UVA, UVB, and UVC rays because most cheap glasses only block UVC rays which are harmless. Polarized lenses are made of special polarized plastic which can block polarized light reflections (or glare) from sources such as water or the atmosphere itself.
How can you tell if sunglasses is polarizing?
Instead of rather a complicated and scientific method, you may simply figure it out with two pairs of glasses. Specifically, hold up both lenses and try looking through them both, then rotate one pair 90 degrees. If the sunglasses are polarized, you will not be able to see through these two lenses once you do this. If you do, one of the lenses is not polarized. What's more, try ooking through your lenses (holding them in your hands away from your face) at a window, TV screen or lake with intense glare. Rotate the glasses in a circle facing the glare. The intensity of the glare should change when you rotate your glasses; otherwise, it's not polarized.
What is the difference between self-tinting sunglasses and polarized sunglasses?
Polarized sun glass lenses are made to neutralize the effect of glare. A 'glare' is caused when the sun's shining rays reflect off a solid surface or water. A 'glare' is typically horizontally polarized. And the lenses are made of vertical polarizes so that they will effectively neutralize the villainous glare! Advantages of Polarized Sunglasses: Polarized sunglasses are specially made for reducing the harmful effects of glare and eye-damaging light. And they are a perfect boon, for all your outdoor activities. http://www.sunglassreplicas.com/Polarized_Sunglasses_s/50.htm i don't know much about self-tinting sunglasses.
How are self tinting sunglasses different from polarized sunglasses?
Polarized sunglasses are designed to vertically filter out glare from sunlight or bright lights. Self-tinting, or transitional lenses, are lenses that turn brighter or darker depending on the intensity of sunlight hitting the lenses.
Are polarized sunglasses better then tinted sunglasses?
Tint is mostly cosmetic. Polarized lenses block the harmful rays and are better for your eyes.

Are polarized lenses darker than others?
yes they have to be a darker shade of color so the meconisms can block the rays
Why are polarized sunglasses such a good idea?
Polarized lenses are extremely helpful when driving, fishing or any sport where there is metal that could potentially direct a blinding glare into your eyes. Polarized lenses are unique in that they reduce light from glare without decreasing the intensity of your entire line of site; moreover, polarized lenses do not simply block the amount of light reaching your eye-instead, they block harmful reflections and glare while only minimally tinting your vision.
What are GPL lenses are they polarized?
In reference to Ray-Ban sunglasses, their GPL lenses are polarized. The GPL stands for Glass Polarized Lens.
How do g 15 xlt lenses compare to polarized lenses?
A polarized lens cuts more reflected glare but the actual protection of polarized lenses and G15 lenses are the same. Polarized sunglass lenses reduce glare reflected off roads, bodies of water, snow, and other horizontal surfaces where the G15 lenses do not.
If you have polarized Oakley half jackets can you put non polarized lenses in the same frames?

no
Should baseball outfielders wear polarized lenses?
I have heard several times that polarized lenses cause slight depth perception issues. A good article that discusses this is found at probaseballinsider.com. I found this article after a sunglsses salesman who played baseball suggested I would be better off without polarized lenses.
