I only have a few minutes, but I wanted to clarify that when I wrote above that it's not a horrible thing, I meant that for me, now, as an adult, it's not even something I think about. I didn't mean to underscore your feelings about it, because I fully understand how it can feel like "one more strike" of unfairness, and no matter how seemingly mild, it's still hard.
My left eye wandered severely to the point of my brain eventually "turning it off", basically my muscle control was so poor, my brain stopped using that eye. I did some combination of patching, glasses, and therapy for 9 years. In som e cases there is a surgery that can be done, I'm not sure why I didn't have it.
Today I have good vision, about 20/30 or so. The issues I have now are because one of my eyes is near-sighted, one is far-sighted. I also have astigmatism, and diplopia (double vision). My vision is good, but my ability to focus is sometimes impaired. Particularly if I have to repeatedly change my focus, for example in school when I had to repeatedly look from my notes to the black board or overhead projector. For some reason lighting changes are especially hard, so the projector was much harder for me than the black/white board. I will see double for fractions of a second until my eyes adjust again. That is tiresome for my eyes, wears on my concentration, and sometimes causes headaches.
I do not have full binocular vision, I often have to close one eye to see things. I can not use binoculars or look through a microscope with both eyes. The image doesn't line up, which drives my eyes/brain crazy (my eyes/brain continuously try to correct it and can't, which tires me and causes headaches).
An ophthalmologist can see my left eye weakness still, but just barely. No one else can see it. No one even knows that I have any vision problems. I do have glasses that I wear when I start to tire, they have a slight prism in them to help correct the double vision.
The only issue my eyes have caused me as an adult is when I tried to enter the military. Diplopia is an automatic disqualification. I was able to get a medical waiver (but I had to go very high up the chain, very high) and I was disqualified from flying (which was fine, I am a Negotiator, I had no desire to fly). I had a little trouble learning how to shoot, particularly from behind a barricade, the split second of delay while I wait for my eyes to focus when I change my gaze was a problem, so I had to learn how to work around that.
But that was it! I served in the military for 4.5 years and now work in Defense Contracting, at a desk job for the most part, and have no issues.
SO...although my eyes were a mess as a young child, they are very functional today!
My ds1's left eye turned in when he was a baby. He ended up having to have surgery, and it was really scary. He was 10 months old at the time and had to wear glasses and do patching. Buuuut he's now 11 and has improved so much that he's out of glasses now, because his vision is better. But, he was so upset about not having to wear glasses again that he asked us to get him ones with just glass in them.
