The Bolle Caen 70373 Gunmetal glasses are stylish and sophisticated, and only for the most serious of glasses-wearers. The rectangular lenses are fully surrounded by a thin strip of gunmetal that continues down through the arms. The unique quality of these frames can be seen in the funky double bridge design, and the stylish combination of metal and plastic covering the remainder of the arms. The plastic tips appear black, but actually have specs of blue throughout. For that hint of added class, the signature "Bolle" name is etched out on the gunmetal temples.
