When in 1917 Giuseppe Ratti started to create glasses in a small laboratory in Turin of other technical quality, designed to ensure optimal protection and vision of aviators and sportsmen, he did not yet know that his commitment would culminate in an international success. Since then, the Protector model worn for the first time by the Italian Aviation pilots has been transformed into the Persol brand. A brand characterized by great technical intuitions, such as the first flexible rods or the famous lenses in yellow-brown color that guarantee a very high sun protection. Persol over the years has been able to win the hearts of great movie stars and sports. Iconic model dedicated to Steve McQueen made famous by the film The Thomas Crown case.
