Aviator sunglasses have come a long way since their introduction in 1936. Initially manufactured for military use, the unique drooping tear-drop frame design has become an iconic fixture of pop culture fashion. Endlessly modified and updated the classic aviator style will never fall out of favor. Durably crafted and exceptional in quality, its no wonder why this is our most popular aviator style. The lens is a shatter-proof polycarbonate composite with a medium smoke tint and finished with a mirror glaze for that full reflective finish and UV400 protection. Complete satisfaction on this item or your money back.
