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. Woven soft and absorbent, your artwork on the front with a crisp white back, made to order. Everyday art for the bathroom, a step past the plain store-shelf towel.
