I was on an ophtho interview and they tested our color vision and stereopsis on the day of ther interview. I was kind of surprised they did that, as it seems like grounds for discrimination.
So I know I've always had problems with the Ishihara tests (stupid dots . . .) so naturally I failed that portion, then they came and gave me the Farnsworth test (the colored tiles you put in order, based on hue). Now that test I passed with flying colors (no pun intended). My question is why can I pass the one test and still not see the numbers in the dots?
