In Turin 1917, Giuseppe Ratti, owner of Berry Opticians, began to make technically advanced glasses designed to satisfy the demands of pilots and sports. The extraordinary characteristics of this innovative product were its design, crystal lenses, the Silver Arrow (both a functional detail and unmistakable decorative element) and the Meflecto patent, a system studied to make the temples flexible and offer maximum comfort. Introduced in the US in 1962, the designs of Persol are timeless.
