The aviator shades as the name implies were originally used in aviation by aviators and air force personnel. The military and other forces also used the same as protective eyewear especially when they are deployed in desert or tropical areas. The aviator shades are designed to keep the strong wind current and dusts or sands away from the eyes of the aviators especially when flying low on open planes. These glasses are smoked or dark colored to protect the eyes from the light of the sun. The aviator and military sunglasses were originally available as supplies for military along with the other tactical gears.
