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. Plush sherpa fleece that gets softer with every wash, printed to order in three sizes. Made to be pulled off the couch and actually used, not folded away like store-shelf decor.
