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. Printed on premium ceramic and made to order, dishwasher and microwave safe, with the artwork wrapping a full 360 degrees. The first cup of the day carrying an artist's point of view instead of a logo.
