Visible light is the portion of the light spectrum, which the eye perceives as color. An excessive amount of visible light is irritating to unprotected eyes and can reduce your visual perception as much as 50%! It can also hinder the eye's ability to adjust to darkness and cause difficulty with depth perception.
Blue Light
Blue light is dispersed through the air by dust particles, which is why the sky looks blue. It also causes glare and is the most demanding of light for the retina. However, if blue light were eliminated, we would lose the ability to see colors, such as traffic lights for example. So, one of the primary tasks of good quality replica sunglasses is to block the correct amount of blue light and to sharpen the contrast without distorting color perception. A neutral gray pair of discount designer sunglasses will provide the least amount of color distortion of all of the lens colors.
