About this tool

Ishihara-style plates hide a number inside a circle of colored dots: people with typical red-green vision separate the figure from the background, while red-green color vision differences often blend the two together. This page draws six plates live on your screen with fresh random dots every time — orange-family digits against green-family backgrounds, mimicking the classic red-green confusion pair. Type what you see plate by plate, skip any you cannot read, and the page shows your score with a plain-English explanation of what plates can and cannot tell you. It is an educational estimate, not professional advice: screens shift colors, lighting matters, and only a certified eye-care professional with calibrated plates can diagnose anything. Treat a surprising result as a reason to book a real exam.
