PseudoChromatic ColorTest

Color-vision deficiency screening to check whether you or someone else may be color blind.

Mobile appfree

A mobile app that uses pseudo-isochromatic plates to screen for color-vision deficiencies, providing a quick way to test oneself or another person when printed plates aren't available. It is intended for informal screening and monitoring rather than a clinical diagnosis, and is suitable for parents, caregivers, or anyone wanting a basic check of color vision.
