Derek Cardigan AF 7509 eyeglasses are simple and timeless. The classic style comes in a glossy acetate finish, accented with silver math symbols, a signature of the Derek Cardigan brand. These glasses are equipped with spring hinges and elongated nose pads for a more comfortable fit on flatter and wider noses.
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.
