Make a bold statement with these Derek Cardigan 7008 eyeglasses. The classic Retro Wingtip style is updated in a slimmer more modern design in matte black acetate. To help show off your geek pride, the division and multiplication symbols are featured on the sides with the equal sign on the arms. For added comfort, the arms are attached with spring hinges.
Bending is better
Spring hinges allow the arm to bend beyond the standard 90-degree angle, so your glasses last longer and fit more comfortably.
