Polarized lenses can protect our eyes from the damage of UV rays. Polarized lenses can change the way light hits our eyes. Polarized sunglasses can give us a clearer view and eliminate glare, this will make our eyes feel more comfortable. Usually they are an excellent choice though they are much more expensive than unpolarized sunglasses, but they have better quality.
I think the polarized sunglasses are better. I have bought two pairs of sunglasses, one is polarized and the other is unpolarized. The apparent difference between them is that polarized sunglasses are more expensive than the unpolarized one. Haha, I also think that the polarized one is more delicate. But the seller told me that the polarized one can reduce the annoying and dangerous glare and prevent our eyes.
Sunlight can be absorbed or reflected in several different directions. Sunlight that is bouncing off horizontal surfaces such as water, land or the hood of a car is usually reflected back in a similar horizontal direction. This reflection produces an agitating source of glare that cannot only create visual discomfort but can also cause a potentially blinding glare. Glare has the potential to create a very dangerous situation, especially while driving. Polarized lenses contain a laminated filter that allows only vertically oriented light to pass through. This blocks the horizontally oriented light so glare is almost eliminated.The most common colors of polarized lenses are gray and brown. However, depending on the manufacturer, many other colors may be available.
