The number one consideration is the quality of polarized sunglasses

The primary function of polarized sunglasses is to prevent ultraviolet rays and filter polarized light. Good polarized sunglasses lenses can block more than 90% of ultraviolet rays from penetrating. Please choose polarized sunglasses with the "UV400" best UV blocking logo; Inferior polarized sunglasses with polarizing filter function, such as dark sunglasses, as the light entering the human eye becomes darker, the pupil of the human eye will become larger, and the ultraviolet rays entering the eye will increase, which will increase the damage to the human eye.

The color of the lens is gray, brown, and green, because the lenses of these colors absorb infrared rays and ultraviolet rays better, which can improve visual contrast and clarity, and the wearing effect is especially good in severe air pollution or foggy conditions.
