The EnChroma Color Blind Test is a proprietary color blind test designed to determine a person’s type and level of color blindness. Created by EnChroma, an independent company based in California, the EnChroma color blind test is the #1 online Color Blind test for color vision deficiency taken by more than one million people worldwide.
The EnChroma test is based on the Ishihara “hidden digit” test method developed by Professor Shinobu Ishihara at the University of Tokyo and is combined with a computer-adaptive algorithm to measure the type and level of color vision deficiency (CVD). The three main types of color blindness are Deutan, Protan, and Tritan. Learn more about the different types of color blindness.
