This is a very common color. It can absorb 95% of ultraviolet light, and some short-wavelength visible light. In fact, this function is similar to that of ordinary untinted lenses, which means that pink lenses 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.
It can absorb infrared rays and 98% of ultraviolet rays. The biggest advantage of the gray lens is that it will not change the original color of the scene due to the lens, and the biggest satisfaction is that it can very effectively reduce the light intensity.
It can be said to be represented by the “Ray-Ban series” lenses, which, like gray lenses, can effectively absorb infrared light and 99% of 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 gray lenses. However, green is still an excellent protective 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 brown lenses is greater than that of gray and green lenses. Therefore, the average person’s satisfaction is also lower. But it provides another color choice, and can slightly reduce the halo of blue light, making the image clearer.
