In 1958 American Optical created the Flight Goggle 58 according to the then new U.S. Air Force Type HGU-4/P aviator sunglasses standard. Type HGU-4/P sunglasses feature semi-rectangluar lenses with less lens surface area and are lighter compared to the preceding Type G-2 sunglasses. The HGU-4/P design frame allowed the visor to reliably clear the aviator's spectacles when a flight helmet is worn, and covers the full field of vision. The frame additionally features bayonet temples designed to slip under a flight helmet or other headgear and were more compatible with oxygen masks. They are commercially known as "Original Pilot Sunglass", and were issued by the U.S. military since 1959 to pilots shortly after the HGU4/P was officially recommended by military optometrists in November 1958. @hepcatstore #americanoptical #staysafe #lund #lundcity
