Maybe this explains why I can pick out so many things that I see in the photos posted on these threads. I have a deficiency in the red/green area of the color spectrum. I'm not color blind, but I can't pick out those damned numbers in the "bubble book". Once I could, then gradually reached the point of not being able to see them. I had to take the more involved method of tests for color vision when I crossed trained into some high tech electronic fields in the Air Force. Then, again, when cross training into the Airborne Radar area and applied for the flight side of the house.
Then, in about 1994, or so, the retina in my right eye became detached and I had to have a surgery procedure that changed my vision in the right eye. Sooooooo, deplated color vision and a large difference in the refractive error of my eyes...........ergo, screwy binocular vision and slight color shift in that area, too.
OOOoooohh, well............back to my box of crayons.
ShortStack. I know what you are talking about. I have a severe red/green deficiency. Kept me out of the Navy back in 1979. I couldnt see those Numbers/letters in those little puzzle blocks.
I see things in rocks and shadows that frustrates me to no end why i can see them and no one else can. That drives me crazy, I'll be trying to show my wife something and she just looks at me like I have lost my mind. She does'nt even want to try to see anymore. How ever I see most the things in the pic's that you guys point out, but I can't see them all. And marks and out lines on the pic's, I can not see a lot of them. The colors blend in to much. That is why I always use yellow or black when I do a mark up.
