Ray Ban Aviators were originally designed for the U.S. Airforce in 1937 as protection for glare and UV rays. It was later released to the public the following year. And soon achieved popularity. But the most imitated of all RayBans(ray ban 3342) is the Wayfarer. It achieved near cult status when Tom Cruise appeared in Dicy Business wearing one.
The Aviator(ray ban 3360) has now evolved in to having different kinds of lens treatment while the Wayfarer(rayban sunglasses) has been fixed with spring hinges and polarized lenses. Both have been recreated with ophthalmic frames and the materials being used are ultra light resins and special metal alloys.
