Color Blindness Test

← All tests

Instructions

You'll see 7 plates made of colored dots. Each hides a number — type the number you see, or press "I see nothing" if no number is visible. View from a normal distance (~70 cm). Screen colors vary, so treat the result as a rough screening only.

Medical disclaimer: These are screening tools only and are still in development, not a medical diagnosis. Consult an eye-care professional for any concerns about your vision.
