Polarized sunglasses have been around since 1936, when Edwin H. Land began trying out making lenses together with his patented Polaroid filter. A lot more sunglasses today have polarized lenses, manufactured from Polaroid polarized plastic sheet, to reduce glare due to light reflected from polarizing surfaces such as water as well as by polarized diffuse sky radiation, or skylight. This can be especially useful when fishing, because the ability to see beneath the surface of the water is vital.
The polarized sunglasses employed by fishermen have polarized filters using the transmission axis oriented vertically to close the sunshine reflected through the water surface. These sunglasses have risen in popularity and is are actually invaluable for those other aquatic events. They are also becoming popular with drivers and then for general outdoor activities.
