The Cheap Ray-Ban sunglasses story starts with an explorer named, Lieutenant John MacCready, who after returning from a balloon flying adventure, complained that the sun had permanently damaged his eyes. He contacted Bausch & Lomb (the founders of Ray-Ban) setting them the challenge to create sunglasses that would provide protection but 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 in at just 150 grams. They were made of gold-plated metal with green lenses made of mineral glass to filter out infrared and ultraviolet rays.
