Persol is an Italian luxury eyewear brand 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 the Italian per il sole, meaning "for the sun". Formed in 1917 by Giuseppe Ratti, Persol originally catered to pilots and sports drivers. Its trademark is the silver arrow (often referred to as the "Supreme Arrow"), and several of the company's glasses feature this symbol.
