Not to thread drift too much, but........
My AME did the "paper ink blot" color vision test where you "see" the green number buried in a pink background. All went well until the last slide. I could not see any number at all. After a long pause, being scared sh!tless and a few, ummm, well - "doc, I can't see any number in there", he said "Good, there is no number there".
I guess he was testing memorizing the color test?
Best of luck to the OP. Always good advice on this forum.
ps Depending on the mood of the AME, I'll pull out the Bugs Bunny answer to the 20/20 vision test - "Acme Vision Printing Company, Copyright 1978".
