Polarized Eye Glasses
Polarized lenses are used in sunglasses to reduce glare from reflective surfaces such as the surface of a lake or the hood of a car. They accomplish this feat through a process called polarization, much like a venetian blind controls sunlight through a window.
Sunlight itself is not polarized - light from the sun will either be absorbed or reflected horizontally, diagonally or vertically. The problem this causes for fishermen and drivers lies in the horizontal reflectivity. Sunlight bouncing off a horizontal surface will strike the viewer's eyes at a similar angle. This means the glare from the surface of the water or the road or the car hood will be strong.
Polarized lenses have a laminated surface containing vertical stripes. These stripes only allow vertically-polarized light to enter the wearer's eyes. Glare is eliminated because the horizontally-polarized light waves cannot bypass the polarized filter.
Reduce eye strain from hours on the computer. Computer glasses are glasses made specifically for the distance people usually work on their computer. This distance can vary greatly from their normal reading range.
It is very important for this distance to be judged on an individual basis. In addition to judging the correct distance for these lenses according to a person's monitor distance, coatings and tints for added eye comfort are added to the lens surface.
