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. Woven from textured polyester yarn with a frayed edge and made to order, it ships with a wooden dowel and cotton cord so it hooks onto the wall in one step. Original artwork with a soft, bohemian texture a flat print can't give a room.
