The lenses are dark and large, offering privacy to the wearer along with great ultraviolet protection. The frame is made of metal, and the arms are made of plastic -- a great combination guaranteeing flexibility as well as strength and toughness. The arms are thick and feature the Khan logo on the side along with several design elements that catch the eye. These shades are available in myriad of color patterns.
