There are many harmful rays in life, and polarized sunglasses can play a certain protective role. Because polarized sunglasses have the function of polarizing light, they can block all harmful rays without affecting the transmission of visible light. There are many colorful lenses of polarized sunglasses. What color lens are best for sunglasses?
Gray Lens
The gray lens can absorb infrared rays and 99% of ultraviolet rays. The biggest advantage of the gray lens is that it will not change the original color of the scene. Moreover, a gray lens can effectively reduce the light intensity.(https://www.koalaeye.com/collections/polarized-sunglasses)
Pink Lens
This is a very common color. It can absorb 95% of ultraviolet light, and some shorter wavelength visible light. In fact, this function is similar to that of ordinary untinted lenses, which means that the pink lens will not have a greater protective effect than ordinary lenses. But for some people, it still helps a lot psychologically because they feel more comfortable to wear.
Green Lens
The green lens, like a gray lens, can effectively absorb infrared light and 99% ultraviolet light. But the green lens will change the color of some scenes and distort it. Moreover, its light-blocking effect is slightly inferior to that of a gray lens. However, green is still as good as an excellent protective lens.
Brown Lens
This kind of lens absorbs the same kind of light as the green lens but absorbs more blue light than the green lens. The degree of color distortion caused by the brown lens is greater than that of the gray and green lens. But it provides another color for people to choose, which can slightly reduce the blue light and make the image clearer.
Yellow Lens
It can absorb 0% of ultraviolet rays and allows infrared rays and 83% visible light to penetrate the lens. The biggest feature of the yellow lens is that it absorbs most of the blue light. Because when the sun shines through the atmosphere, it is mainly represented by blue light. After the yellow lens absorbs blue light, it can make the natural scene more clear. Therefore, the yellow lens is often used as a 'filter' or used by hunters when hunting. However, no one can prove that the target shooting performance is better if the shooter wears yellow glasses.
