Sunlight itself is not polarized, however sunlight will either be absorbed or reflected horizontally, diagonally or vertically. Reflections from the sun that bounce off a horizontal surface strike our eyes at a similar angle which, in turn, means glare from the surface of the water, car hood while driving and road will be strong. The surface of polarized lenses contain vertical stripes which only allow vertically-polarized light to enter our eyes. Glare is eliminated because the horizontally-polarized light waves cannot bypass the polarized filter and a reduction of glare is more noticeable. As glare can easily distort color and objects, polarization is preferred by most sunglass-wearers, especially on bright, sunny days.
