Sleek and stylish, these metal glasses by Khan are for men who want to look studious and serious. The metal frames are flexible and strong, fitting snugly on the head and face. The arms are straight and curve at the ear, downward and to the inside as well for a better fit. The lenses are rectangular in shape, and although clear, still offer ultraviolet protection. These nice looking sunglasses are available in a wide array of highlight colors sold by the dozen.
