The Harvard Full Lens Sunglass Reader is a round retro style that looks perfect for a professor or any academic type. The frame is only 4 3/4" wide at the temples, so it works great for someone with a narrow face. It comes in a tortoise-shell frame (shown second from bottom in photo) or a bright red face with a tortoise arm (shown in the middle of the photo). The frame has a spring hinge for a comfortable fit. Frame Measurements: 4 3/4 x 1 1/2" (temple to temple x height of lens)
