A dense technical diagram displays the mechanical components and instruments of optometry equipment rendered in fine black line work against a white ground. The composition centers on a large phoropter flanked by smaller optical tools, lenses, and testing devices arranged in a systematic, patent-drawing style that captures the intricate engineering behind vision correction. At home in a medical office, optometrist's workspace, or a professional's study. Printed to order directly onto lightweight aluminum with a high-gloss finish that makes color and detail pop and resists fading over time. A wood backing floats it about three-quarters of an inch off the wall and holds the wire or sawtooth hanger. Available from mini to large, it is original art with a modern, durable edge, not a quick print off a shelf.
