This black t-shirt features a playful design based on the Ishihara color blind test. A line of five colorful, dotted circles stretch across the chest. Beneath each circle is a single word: "Drink," "Sleep," "Shower," "Eat," and "Hug." This design is cleverly juxtaposed with the phrase above, "If you can't see the number you need to." The shirt is made from a comfortable-looking fabric. It's perfect for casual wear, sparking conversations, or as a fun gift for anyone with a sense of humor or an interest in vision science.
