Color Blind Test & Simulator

Do you see colors the way most people do? Take the quick color blind test in about 2 minutes, see pictures through color blind eyes in the color blind simulator, then try nine more self-checks for your eyes. Vision Test is a screening and awareness tool. It is not a medical device and it does not diagnose anything.

🎨 COLOR BLIND SIMULATOR

• See pictures the way people with protanopia, deuteranopia, tritanopia or achromatopsia see them
• Set the strength with a slider, from mild to full
• Hold to compare with the original colors

• Anomaloscope (simulated) — mix red and green to match a yellow

⚕️ IMPORTANT

Vision Test is for screening and education only. It is not a medical device and cannot diagnose, treat or rule out any condition. The tests are inspired by classic methods (Ishihara, Farnsworth D-15, Snellen, Tumbling E, Amsler grid); the color plates are drawn by the app and are not the original printed charts. Results on a phone screen depend on your display, brightness, lighting and viewing distance. If you are worried about your eyesight, or you notice a change in your vision, please see a qualified eye care professional.
