Persol is an Italian luxury eyewear company specializing in the manufacturing of sunglasses and optical frames. It is one of the oldest eyewear companies in the world. The name is derived from "per il sole," which, in Italian, means "for the sun". Formed in 1917 by Giuseppe Ratti, Persol originally catered to pilots and sports drivers. Presently, the company is famous for its durable sports sunglasses. Its trademark is the silver arrow (often referred to as the "Supreme Arrow"), and several of the company's glasses feature this symbol.
In 1917 Giuseppe Ratti, owner of the Berry optical, starts producing his first glasses and lenses for athletes and aviators. Persol was a heavy influence in the production of sunglasses. The company developed the first flexible stem, known as the patented Meflecto system, which was one of the first spring hinges ever developed for eyewear. Persol was introduced to the United States in 1962 and opened its first boutique on Rodeo Drive in Beverly Hills in 1991. It is currently owned by the Luxottica group.
Currently all "plastic" Persol spectacles are made in Italy using cellulose acetate, a hypoallergenic material derived from cotton. The lenses for the sunglasses manufactured by Persol use a crystal lens to filter harmful light from the wearer's eye.
