Ray-Ban is a high end manufacturer of sunglasses, founded in 1937 by Bausch & Lomb. They were introduced for the United States Army Air Corps. In 1999, Bausch & Lomb sold the brand to the Italian Luxottica Group for a reported $640 million. The 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 infrared 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.
