I had an exciting thought the other day when I was thinking about the different things that people talk about when they've gained stereopsis.
One of the things is what Heather said about how her perception of color had improved. It makes sense why this would happen, because fusion would increase the resolution of all facets of vision--not just acuity. After all, now all of a sudden, you're processing information from twice as many cone cells.
Then that made me think about myself when I was at MEPS (military entry processing station). When I was 19 I had thought about going into the Air Force. MEPS is where the military is able to put a dollar amount on how much you're worth to them. You do urinalyses, they test your hearing, mental faculties, they test for physical abnormalities by stripping you to your underwear and having you walk like a duck in a room full of other men.
They also put you through a battery of vision tests. I did alright, but I failed two tests: depth perception (obviously), and color vision. I'm not color blind exactly, but instead, I have color deficiency. It surprised me to learn this because I always thought that I saw colors vibrantly. But apparently, according to this test I don't.
That is the type of color test that I did. I would have failed at this particular test. I do not see the hidden number or letter that's in it. Is it a two, by chance? No! It's a three. Right? /facepalm
But I wonder if the reason I'm color deficient is because I'm only using half of my cone cells (cones, not rods are the cells that provide a sensitivity to color). It'll be interesting to know whether my color perception is enhanced like Heathers to the degree that I'm able to pass the color test. That's another question that I want answered!--and another answer that I expect to have answered soon. The day can't come soon enough.
