Aviator Sunglasses

Unlike other best place to buy cheap sunglasses, aviator sunglasses were first meant to be worn under headgear. Because of this they have thin monel, steel, or titanium frames and instead of being flat, the lenses are slightly convex. This allows them to cover the entire field of vision of the human eye, reducing the mount of light entering the eye from any angle. The lenses themselves are usually very dark and sometimes reflective. The double bridge is one of the defining characteristics of the aviator sunglasses. Some have flexible cable temples that hook more securely around the ears to keep them in place.
