Just yesterday I had a medical checkup for preemployment for a company. I was given a few pages book to read. Each page had a background of colourful dots, and a letter like a,b,c,14,16, etc. on it made of same size dots but with a very little noticable colour difference from the background colour dots. One must recognize it correctly! Have any of you has had such an experience? I never knew that I was partially colour blind, i just can't beleive it and am quite depressed!
But I think the world is really colourful! So can it happen that the doctor is wrong?
