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. A glossy-finished set of four, made to order. A bold way to bring an independent artist's work into the room without committing to a large piece, whether on the dining table or the bar at your next party.
