Aviator
Thin metal frames with large teardrop lenses and a double bridge, first made for pilots.
Also: aviator sunglasses, pilot glasses
Aviators have large teardrop-shaped lenses, a thin metal frame and a double bar across the bridge. Bausch and Lomb developed them for American military pilots, and in 1937 sold them to the public under the Ray-Ban name. Their size was chosen to cover the eye's field of view at altitude. They became a lasting fashion through the twentieth century, and stylists say they suit oval, square and heart faces.
