"Reading glasses are reading glasses," you might think, until you see these stylish and eye-catching glasses by Khan. The frames are metal, and the arms are plastic, designed for flexibility and durability. The lenses are small and rectangular and set in the thin metal frame of the face with added nosepieces for tighter fit. The arms have the Khan logo and feature a sweeping shape that curves downward at the ear. You can choose all black or select different arm and frame color combinations from the assorted-color dozen.
