In 1999, Bausch & Lomb sold Ray-Ban to Luxottica Group S.p.A. of Italy for $640 million.[18] In 2001, the Wayfarer underwent a significant redesign (RB2132), with the frames made smaller and less angular, and changed from acetate to a lighter injected plastic.[17] The changes were intended to update the frames' style during a period of unpopularity and to make them easier to wear (the frames' previous tilt made them impossible to perch on top of one's head, for instance).[17]
