Among them, ultraviolet rays cause serious damage to human skin, eyes, etc.; the rays released by sunlight, IR (Infra-red) infrared rays (750nm) and above, visible light ray (310~780nm); Ultraviolet rays are divided into UVA, UVB, UVC (310nm) and above, blue light (Blue light) of which UVA, UVB, UVC are harmful rays,

if our body are exposed to those harmful light for a long time,  it will be injured.UVB has a serious impact on vision, ( Tanning Ray) is the light that burns the skin. Most of the corners of the eyes will absorb this UVB light, so this light must be blocked. The function of polarized sunglasses is to polarize sunlight,  it can block all harmful light but affect the transmission of visible light, which can truly protect the eyes and let us to have a more clear vision. Except the basic anti-ultraviolet function, polarized sunglasses also have features of anti-glare, anti-reflections from road and water, etc., extremely suitable for driving, fishing, traveling, and daily wearing.
