Meet Chief, a sturdy and striking pair of eyeglasses for men designed for those who like to take charge of their look. These wider, square-shaped frames were constructed in high-grade acetate, and lend a professional panache to your entire look from head-to-toe. Choose Tortoise Matte, for a richly smooth finish, Golden for that a barely-there frame, and Onyx Clear, a dual-tone acetate pick that gradually fades from black to clear. More than just good looks, Chief has been fabricated with an improved-quality hinge. To ensure this style's durability this style has been tested more than 25,000. This means you're getting a more flexible hinge that can withstand tension for longer wear.
