Carrera offers the CA180/F for the man who covets chic designer eyeglasses, but needs an alternate fit. The round rims are crafted in hypoallergenic stainless steel for superior comfort and strength. The ultrathin temples are made in lightweight, corrosion-resistant metal, and come with plastic socks over the tips for stability and comfort behind the ears. The flexible spring hinges retain their initial balance and adjustment, keeping the glasses in place throughout your busy days. These Carrera glasses come in an alternate fit design that prevents slipping on the nose, making them ideal for the man with high cheekbones and a wide nose bridge.
