What is it about aviator shaped frames that men love so much? Is it the association with being a pilot, roaming the skies at complete liberty like a bird? Or is it a reminder that men are men and pilots are men, and aviator frames are used by men for manly pursuits? The aviator shape became popular in the 1940’s when pilots used them in their sunglasses. But the fashion has remained ever since and extended to men eyeglasses. Most men’s aviator-shaped eyeglasses are made of metal, and include a double-bridge construction. This adds to the strength of the frame, and to the durability, and to its ability to hold up a high-prescription lens, and a multifocal, progressive, bifocal, or trifocal lens. But let's not forget about the look: real men wear aviators.
