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.
