Aviator sunglasses

Encyclopedia : A : AV : AVI : Aviator sunglasses

Aviator sunglasses are a type of sunglasses that originated during World War II, as pilots in the war found a need for sun and glare protection to aid them during day missions and dog fights. They are characterized by a metal frame, with the ocular perimeter being 2-3 times the area of the eye socket, and dark reflective lenses, contemporary models are often polarized. The large lenses are not straight as in eyeglasses but bulge out slightly. The design attempts to cover the entire range of the eye and prevent as much light as possible from entering the eye socket from any angle. While still immensely popular with military and civilian aviators alike, the sunglasses work quite well and are usually seen as fashionable and have been taken up by the civilian population. Law enforcement officers have also taken a liking to the glasses for many reasons, from their excellent cancellation of glare and can stop eye contact, adding to the air of authority they can lend.
