Many people think that the darker the color of sunglasses, the better the isolation of ultraviolet light, this view is incorrect.
The real situation is that the function of sunglasses in filtering ultraviolet light is only related to the coated film, and the darker the color, the better. Drivers who drive long distances, in particular, are more likely to tire their eyes if they wear too dark sunglasses, and it will be more dangerous to enter places with dim light, such as tunnels, from strong sunlight.

Why do sunglasses have to buy polarized sunglasses?
General sunglasses only use the effect of dimming, which is because the general lens can not filter the light, so it can only reduce the intensity of glare and ultraviolet light, and can not completely block these harmful light, so its function is only to reduce the damage to the eyes.
Different from the general sunglasses, polarizing lenses can completely block the dazzling glare caused by scattering, flexion, reflection and other factors because of their polarizing properties. At the same time, it can also completely block the harmful ultraviolet light to the human eye, so that when people move in strong light for a long time, the eyes are not tired, to achieve the function of real protection, and can make the things seen more clear and three-dimensional.
