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. Ray-Bans were created in 1937. Some years earlier, Lieutenant John A. Macready returned from a balloon flying adventure and complained that the sun had permanently damaged his eyes. He contacted Bausch & Lomb asking them to create sunglasses that would provide protection and also look elegant. On May 7, 1937, Bausch & Lomb took out the patent. 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.
