EnChroma has taken color blind testing to the next level. Unlike old and outdated Ishihara tests developed back in 1917, our new color blind test uses the science of cone isolation to test the sensitivity of each of your eye’s three color-sensing cones and scores them to show you how close or far you are from having normal color vision. And, unlike any other color blind tests on the internet, our new color blind test can be taken while wearing EnChroma color blind glasses so you can compare your before and after results to see the improvement in your color vision deficiency.
