Ray Ban

Ray-Bans were created in 1937. Some years earlier, Lieutenant John MacCready 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.
