Aviator sunglasses, also known as pilot shades are a style of frame developed by Ray-Ban. Aviator sunglasses were given their name due to their oblique teardrop shape, which matched those of the smoked-lens flying goggles which Ray-Ban was then selling to the Army and Navy.
Aviators are characterized by dark, often reflective lenses having an area two or three times the area of the eye socket, and metal frames with either paddles or wire temples which hook behind the ears. The large and slightly convex lenses are designed to prevent as much light as possible from entering the eye socket from any angle.
Ray-Ban was founded in 1937 by Bausch & Lomb, an American company, one of the world's leading suppliers of eye health products. Their prototype, known as Anti-Glare, had an extremely light frame weighing 150 grams. They were made of gold-plated metal with green lenses made of mineral glass to filter out infra-red and ultraviolet rays. Pilots in the United States Army Air Corps immediately adopted the sunglasses. The Ray-Ban Aviator became a well-known style of sunglasses when General Douglas MacArthur landed on the beach in the Philippines in World War II, and photographers snapped several pictures of him wearing them.
