The Nautica N4022 Black are a stylish pair of eyeglasses that feature narrow stylized rectangular shaped lenses rimmed in a lightweight yet durable black matte frame. What makes these frames so special are the polarized clip on lenses that come with the frame. Magnets allow the clip on to be removed and replaced easily and with no fuss. They're perfect for those who frequently run in- and outdoors. For added comfort and style, these tough frames have adjustable nosepads, reinforced temple pieces - and even spring-hinges for added convenience!
