American Optical Eyewear earned its reputation for outstanding optics as a top supplier to the U.S. Military. In 1958 the company developed Flight Goggle 58, now known as the Original Pilot Sunglass, to provide military pilots with maximum protection, optical performance, and comfort. Original Pilot Sunglasses have protected thousands of military pilots from blinding glare. They were even worn by the Eagle flight crew in the first moon landing. If you want fashion and comfort, plus the optical performance demanded by U.S. Military pilots, look to American Optical Eyewear. Larger frame 57mm MATTE(SILVER) bayonet, smoke shade.
