Optometrist's antique trial lens frame with eye chart. Steampunk Glasses. Small size. Please note there is a missing knob on the one side of the top - please see pictures. It looks as if a pocket watch knob would work as replacement. Lens turn free to adjust size. Arm pieces are in tact and move freely. The glasses measure 4 inches across from the bases of the arms. Please see and enlarge pictures for condition details and authenticity. Our pi...ctures are part of our description. If you have any questions or need additional pictures please just let us know.
