All eyes need protection from the burning rays of the sun. In the visual spectrum ultra violet light is broken into three categories. The shortest wavelengths, UVC are absorbed in the atmosphere and never make it to the surface of the earth. The middle range (290-315nm), higher energy UV B light burns your skin and are absorbed by your cornea, the clear window on the front of your eye. The longest region (315-380nm) are called UVA rays pass to the interior of your eye. This exposure has been linked to the formation of cataracts as this light is absorbed by the crystalline lens. Once the cataract is removed the very sensitive retina is exposed to these damaging rays. Most modern lens materials naturally absorb these burning rays of the sun. A specialize filter can also be added to basic lens designs to offer this protection.
