Dating back to the 1930s, Ray Bans started when Bausch & Lomb designed sunglasses for U.S. Army Air Corp pilots to protect their eyes against the sun. These "aviator glasses" became a hit and the term now describes all sunglasses with designs that are of a similar shape. Ray Bans is known for their classical frames that have been worn by stars and in movies. Famous models include "Aviator," "Wayfarer," "Clubmaster," "Justin," and "Erika."
