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 green is shown in second from top and the turquoise blue is shown at the bottom 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)
