Vintage Alpha Optics reading Sunglasses

These are vintage reading sunglasses by Alpha Optics. Brown metal frame and brown lenses, I would estimate that the diopter is 1.75 or 2.0. The full specification of the color and size and model is printed on inside of the arm. The item is in very good used condition, except for the missing nose piece, which is easily replaceable.
