Color Blindness Test by EnChroma

By EnChroma

Open iTunes to buy and download apps.


This app tests your color vision to determine if you have color vision deficiency (also called color blindness). If so, it measures the type and extent of the deficiency. 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.

I'm sure if you have the standard red/green color deficiency ( you probably already know & ) this is great. But if your color vision is more subtle, this is a waste. Even for free. I didn't know til HS that I was colorblind - after arguing with my mom about a paint color. And though its extensive, it's all light or dark hues of primary & secondary colors that I can't really "see". This test doesn't even touch that.

Worthless. Complete waste of time.

I did the test several times and it kept saying there was a problem with the results. Mostly I was not sure what I saw.

Finally I just typed random answers of seeing a circle, square and diamond without even looking to to see what I saw and it said my color vision was just fine.

How can apple approve crap like this? Don't they even test apps any more?


The other people are trolls, it doesn't require an email address. Anyways, it works very well.
