PseudoChromatic ColorTest 3.0

Do you or someone you know experience color vision deficiency?

Contrary to the term color blind, individuals with this condition are not blind to color but rather color deficient. While they can see colors, their perception is different from those without color vision deficiency.

Approximately 1 in 20 males and 1 in 200 females face color vision deficiency.

This genetic trait is passed from a mother to her son. As an example, if the grandfather is color blind, there is a possibility that the grandson may also have this condition.

This app features a series of images that aim to assess congenital color vision deficiency quickly. This test is based on the Ishihara Color Test, named after Dr. Shinobu Ishihara.
