Sunglasses are in fair vintage pre-owned condition, both lenses have scratches (see photos). Size: 57-12-115. Made in USA. Please see pictures to make your complete condition assessment. The lenses were made to a joint standard shared by the U.S. Army Air Corps and the U.S. Navy. As a result, the lens carried an “AN” (Army/Navy) specification number: the AN6531. The U.S. Government specified the shape of the lens and the color, which was initially a 50% green tint. This tint proved insufficient to protect pilot’s eyes from sun glare so this lens was superseded by the AN6531 Type 2 lens in rose smoke. Various contractors made the frames and ground the lenses. These included American Optical, Bausch & Lomb, The Chas. Fischer Spring Co. (which primarily made AN6530 Goggles) and Willson. Frame and hinge design varied slightly from contractor to contractor.
