UV stands for ultraviolet light or radiation, and as most people know can be extremely harmful UV. You may have seen different anti-UV as skin lotions, windbreaks, screens, lenses and sunglasses. UV radiation can damage our skin, the house and cars, but what does that mean? There are basically three types of UV rays that you should be aware of (UVA, UVB and UVC). UVA radiation is a wave of light that travel in a rocker and affect your sharpness. UVA affects your perception of depth or distance of objects for you, as a vehicle or person on the roadside.
UVB rays are a wave of light that travel in a movement from left to right and that causes sunburn and heat. UVB rays are what trip through a magnifying glass to light, use and exposure may cause redness and burning your skin. UVC rays are a wave of light traveling in a forward motion and is very dangerous because it can cause cancer. Most people do not know that your eyes are sensitive and are vulnerable to this kind of light wave.
To summarize the above descriptions that affects vision UVA, UVB burn, and UVC can cause cancer. So I highly recommend Ultra Violet protection products have especially the sunglasses.
