Light when reflected from another surface reveal many fascinating properties, one of these is known as polarization. Polarized prescription sunglass utilizes this property of light to reduce the glare from surfaces such as glass, snow and water. Generally a source of light produces waves which spread in all direction. When light bounces from flat road surface or smooth water surface, these light waves are horizontally polarized which implies that they move along an axis which is generally horizontal.
