Aviator eyeglasses frames are characterized by dark, often reflective lenses and very thin metal frames with double or triple bridge (so-called ″bullet hole″) and bayonet earpieces or flexible cable temples that hook behind the ears.

During World War II, people always connect the frame glasses the aviators and navy used during war with heroism, which make the incredible popularity of these sunglasses. But, as we known, the aviator frames appeared before World WarⅡ. When during the flight training, the pilots also need another frame under the protective glasses to resist the sunlight and low temperature. Fast forward for a few dozen years, these frames swept the whole world.
