It is an easy app to use to take the Isihara Color Blindness test. The biggest problem is that many of the plates/numbers are not available. I know that I have tritanopia and there are plates in the original I cannot see. This app could improve by adding those plates and including what the results could mean if you do or don't incorrectly guess the plate numbers. It gives a percentage grade at the end, not a potential of color blindness or lack thereof.

I definitely have colourblindness but was able to get to the end and have "normal vision" apparently. I think the tests could be better. the number recognition ones are fairly good but the line ones are vague but easy to guess currently.

I use your color blindness test on occasion, 2 years ago my eye doctor at the time told me I was going blind. Yes things are progressively getting darker but when I started your test I came to realize that I was missing more than half the numbers in your test. I have since got on two supplements that work extremely well. Today I miss three! It's not perfect but it's light years better. The eyes are much happier and healthier. Thank you for your help.
