Product Features

  • 8% of men and about 1% of women have red-green color blindness.
  • Among those with red-green color blindness, there are two types: 75% are deutans, and 25% are protans.
  • Deutans have an anomaly in the green-sensitive cone cells, and protans have an anomaly in the red-sensitive cone cells.
  • Conventional color blindness tests require special light sources and a trained test administrator.
  • The EnChroma test is self-administered and only takes 2-5 minutes to complete.
  • Many tests out currently found on the internet are not accurate and don't provide any information about the type and extent of the color vision deficiency.

Product Description

Are you color blind? EnChroma presents the first scientifically derived Android app for testing the type and extent of the deficiency. The application is the result of years of work devoted to the study of Color Vision Deficiency supported by several National Eye Institute grants. Unlike other applications which are little more than crude approximations of the Ishihara plate test, this test is designed with an advanced algorithm for testing CVD.

At the end of the test the test results will display and you may also email them to a friend. It will also recommend which EnChroma glasses are right for you if you are interested in color vision enhancement.

5.0 out of 5 stars Helpful insight into color-blindness June 5, 2013
Verified Purchase
This simple test helped me understand my husband's color-blindness better than our 23-year long discussion of it. ;) It is simple to use, gives the one affected their dignity and can be done anywhere at any time. This doesn't take the place of a medical diagnosis, but it does supplement it nicely.

5.0 out of 5 stars color deficency degrees. June 16, 2013
Verified Purchase
The free test gives you an idea of how deficient your color sense is and what colors.There is a sales pitch at the end for a pair of lens but at $599 they are a bit high .

5.0 out of 5 stars Good Test April 25, 2013
Verified Purchase
I wanted to test my daughter. Helped me make sure she wasn't color blind. My two year old was able to distinguish the color variations and liked that they came in bubbles.
