Welcome to the EnChroma

Color blind Test

If you have color blindness, our test can tell you if your color vision deficiency is mild, moderate, or strong — in less than two minutes.

For kids 5+ take the test in shape mode.

About the EnChroma color blind test

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. Learn more about the different types of color blindness.

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.

EnChroma Patented Lens Technology

EnChroma glasses for color blindness are uniquely engineered to give those with color blindness the ability to see more of the broad spectrum of bright color most of us take for 

granted. Utilizing a patented light filter technique, our lens technology is applied with mathematical precision to address common forms of red-green colorblindness. Learn more about how EnChroma glasses work.

The EnChroma Color Blind Test is designed to assess whether a person has color blindness, and inform those with color blindness which type of color blindness. In rare instances, due to screen resolution, lighting conditions, and other factors, this test may produce inconsistent results. If you are unsure about your results, consult with an eye care professional.
