This unique black t-shirt features a playful design based on the Ishihara color vision test. Above five colorful dotted circles, the humorous text reads: "IF YOU CAN'T SEE THE NUMBER YOU NEED TO." Underneath each circle, it lists what you need to do: "DRINK WATER, SLEEP, SHOWER, EAT, TRAVEL TO PARIS." Made from a comfortable-looking fabric, this t-shirt is perfect for anyone with a sense of humor or an interest in vision and perception. It's a great conversation starter and a fun way to show off your quirky side. Wear it casually or give it as a unique gift to friends and family.
