The edge of the body characteristically drooped away at the edges by the cheeks in a sort of tear fall condition, to give a complete all-spherical safety to the pilots eyes, who regularly experienced to glance down in direction of the aircraft’s instrument panel. The polarized lens minimized the glare from light-weight mirrored off the instrument panel. Pilots were being presented these sun shades free of charge of charge, but in 1937 the standard general public have been authorized to buy this aviator-type design that “banned” the sun’s rays as Rayban sun shades.
