Ray-Ban's history dates back to when explorer John MacCready complained that the sun had damaged his eyes during a trip in an air balloon. He contacted U.S. company Bausch & Lomb and commissioned them to create sunglasses that would both provide complete protection and be aesthetically appealing. In 1937, Bausch & Lomb took out a patent on the model it had designed – “Anti-Glare” – which had an extremely light and thin frame and lenses made of mineral glass to filter out infrared and ultraviolet rays. Ray-Ban continued to develop its patented technology, including developing the Aviator model for pilots in the US Air Force. Its vast experience and great knowledge allows Ray-Ban to offer perfect protection of the highest quality for your eyes.
