Aviators are a sunglass design with oversized teardrop-shaped lenses and a thin metal frame. The design was introduced in 1936 by the Ray-Ban company for the issue to U.S. military aviators. Their popularity with pilots, military, and law enforcement personnel in the United States has never wavered.[citation needed] As a fashion statement, aviator sunglasses are often made in mirrored, colored, and wrap-around styles. In addition to pilots, Aviator-style sunglasses gained popularity with young people in the late 1960s and continue to be popular, with only a brief fall in demand during the 1990s.
