Persol Men's 0PO0649 Round Sunglasses

A style icon, the 649 is unique, because it features Victorflex with other classic Persol design qualities. Victorflex is a system that gives the bridge maximum flexibility, while standing out as an original and iconic design. Created in the 1930s as a derivative of Meflecto, Victorflex is a unique flexible bridge, made by inserting two steel strips into the acetate and cutting three vertical slits on the bridge. Five intricate manual steps are needed for this process. Interestingly, Victorflex is shown to its full potential, giving a glimpse of the steel through the acetate, on the patented dappled color Persol frames.
