More Information About Color Blindness

Normal vision means you have normal photopigments, or color-detecting molecules, that allow you to see a full array of colors. Color blindness or deficiency, means your photopigments are abnormal causing your color perception to be limited and inaccurate.

There are 3 main types of colorblindness; take the color blind test to find out if you could be colorblind. If you believe you could have color vision deficiency, consult with your eye care professional.

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 tool for color vision deficiency taken by more than one million people worldwide.

The EnChroma test is based on the Ishihara “hidden digit” test method and is combined with a computer-adaptive algorithm to measure the type and level of color vision deficiency (CVD). It is available in a numbers mode for adults and children ages 10+ and in a shape mode for kids ages 5+. The three main types of color blindness are Deutan, Protan, and Tritan.


before taking the test

The EnChroma Test, like all Color Blind plate tests, are not performance evaluation tools and are NOT designed to be taken with glasses with colored lenses of any kind. As a result, please be sure to do the following BEFORE taking the test:

Remove all glasses with colored lenses. The test is designed to be taken with the naked eye or with a prescription if you wear one. It will not work with colored lenses of any type and will lead to inaccurate results. Taking the online test with color correcting glasses to “prove” that they work is a misconception and inaccurate.
Turn brightness on screen to high. Light affects color and the ability to perceive differentiation.
