Neat!!!!
I think this is a cool app. You press on the square that's a different color, and you keep on playing until you hit all 255 squares. Each time you press the different colored square, it blends in more and more to the background. I don't understand how this can be useful before seeing the eye doctor though.Show lessYou have got to be kidding me
Seriously all you do is press a black square 225 times every color and the is 5 different colors it's stupid don't download this has nothing to do with vision
