COLOUR BLIND TEST

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

Start the Test

Before taking the test

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

  • Remove all glasses with coloured 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 coloured lenses of any type and will lead to inaccurate results. Taking the online test with colour correcting glasses to “prove” that they work is a misconception and inaccurate.
  • Turn brightness on screen to high. Light affects colour and the ability to perceive differentiation.
Start the Test

About the EnChroma Colour Blind Test

Based on Ishihara Colour Blind Test

The EnChroma Colour Blind Test is a proprietary colour blind test designed to determine a person’s type and level of colour blindness. Created by EnChroma, an independent company based in California, the EnChroma colour blind test is the #1 online Colour Blind tool for colour 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 colour 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 colour blindness are Deutan, Protan, and Tritan. Learn more about the different types of colour blindness.

EnChroma Patented Lens Technology

EnChroma glasses for colour blindness are uniquely engineered to give those with colour blindness the ability to see more of the broad spectrum of bright colour 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 colour blindness.

The EnChroma Colour Blind Test is designed to assess whether a person has colour blindness, and inform those with colour blindness which type of colour 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.
