The Yuba is a contemporary unisex style that looks good on almost everybody. It's a medium-coverage, medium-sized frame, and one of the top pairs we recommend to our community. This modern classic is a bestseller for good reason. SuperLight is created from scrap plastic that would otherwise end up in a USA landfill. They intercept this scrap plastic from the waste stream and reformulate it into their SuperLight polycarbonate resin.
