Young Brunette Girl With A Navel Piercing, Earrings And Sunglasses Reveals Her Black Bikini At The Sea

The first sunglasses used in a Moon landing were the original Pilot Sunglasses produced by American Optical. In 1969, they were on board the Eagle, the lunar landing module of the first manned mission to land on the Moon (Apollo 11). – NASA research primarily by scientists James B. Stephens and Charles G. Miller at the Jet Propulsion Laboratory (JPL) resulted in special lenses that protected against the light in space or the light during laser and welding work. The lenses used colored dyes and small zinc oxide particles; zinc oxide absorbs ultaviolet light and is also used in sunscreen lotions. The research was later broadened to further terrestrial applications, e.g., deserts, mountains, or fluorescent-lighted offices, and the technology has been commercially marketed by a U.S. company. Since 2002, NASA uses the frame of the designer model Titan Minimal Art of the Austrian company Silhouette, combined with specially dark lenses developed jointly by the company and "the" NASA optometrist Keith Manuel. The frame is noteworthy in that it is very light, weighing under 10 mg, and contains neither screws nor hinges, so that no small pieces can loosen.
