American Optical Eyewear earned its reputation for outstanding optics as a top supplier to the U.S. military. In 1958, they developed Flight Goggle 58 (now known as the Original Pilot® Sunglass) to provide military pilots with maximum protection, optical performance & comfort. The rugged, sturdy structure and high quality finishing of the steel alloy frame coupled with distortion free, toughened and polished 52mm True Color® grey glass lens have made American Optical Eyewear the standard bearer of all fine military sunglasses. Choice of gold, silver, or black frames. Comes with Manufacturer's warranty.
