Ishihara-style plates generated on the fly. Read the hidden digit, get screened for normal / red-blind / green-blind vision.
Plate type: —
Each plate is generated on canvas — a field of random dots in two palettes, with a hidden 1–2 digit number. Type the number you can read and Submit. Normal vision sees the “normal” digit; red-blind (protanopia) sees the “protan” digit; green-blind (deuteranopia) sees the “deutan” digit. Across 8 plates the tool aggregates which type you read most often. Tip: this is a screening aid, not a medical diagnosis — see an eye-care professional for clinical assessment.
