Ray Ban sunglasses came into existence in 1937 when the brand was founded by optician supplies and spectacle manufacturing firm Bausch & Lomb (which had been established in 1853 by two German immigrants and had gone from strength to strength). The first model of Ray Ban sunglasses was designed at the request of a US pilot who had complained of the sun damaging his eyes while he was flying. This design was originally called the Anti-Glare but was soon renamed the Aviator due to its popularity and suitability to pilots. It consisted of a distinctive design where the lenses were two or three times the design of the eye socket because they needed to block the entire range of the eye from the sun. The first Ray Ban sunglasses were consequently worn by pilots in the US air force although it was only a year before the company began to sell them to members of the public.

On May 7, 1937 Bausch & Lomb officially took out the patent on the Ray Ban aviator sunglass.

The first sunglass to incorporate an anti-glare lens, the metal frame was extremely lightweight and made from gold-plated metal with two green lenses that filtered out UV rays.

The U.S. Army Air Corps pilots instantly took to the sunglasses, earning Ray-Bans the moniker "Aviator Glasses" -- a term which now describes all sunglasses with designs that are similar to the original Ray-Ban.

The Ray-Ban aviator achieved broader popularity during WWII, when General Douglas MacArthur was photographed in Ray-Ban aviator glasses landing on the beach in the Philippines.
