Mine weighs to 2 grams.
I've never had depth perception but I can't for the life of me figure out why someone would voluntarily get rid of it. Everything to me looks like a 2 dimensional photograph/picture. I guess you could get 2 pair of glasses, one that makes your near eye clear at distance and vice versa.
Babies' eyes do not initially focus, when they start to do so the brain has to figure out to point them at the same object so there is convergence and a single image. If that doesn't happen, you have double or blurry vision. With a lack of convergence your brain can choose to to remedy that in various ways. One is to ignore the input from one eye. Another is to move one eye in or out so there are 2 clear images. This happened in my case, my eyes turned in (esotropia) when I was very young. My mother figured out there was a problem when I walked between 2 trees. Except there was only 1 tree and I walked right into it. So they did surgery on my eyes, moved the interior muscles on both eyes. That is just dandy but it doesn't fix the problem, brain doesn't know it is supposed to fuse the images. So then it decided that my left eye should go out (exotropia. Both terms are a form of strabismus). So they did some rudimentary vision therapy - eye patching, red/green glasses.
Eventually my brain decided to mostly ignore one eye or the other, VERY gross color and motion only. I have the ability to choose which eye I use (not always the case and some people never see out of one eye even if they don't show signs of strabismus, some alternate ) and when I focused with my left eye, my right eye stayed straight, just no vision. When I used my right eye, my left went out pretty far. They decided to fix that by moving the exterior muscle of my left eye when I was still < 2 Y/O I think. Did no good, eye started going back out pretty immediately. So in 6th grade they decided to fix it and did the same thing to my right eye. Dandy, now whichever one I wasn't focusing went out. 11 years old, 3 operations with no improvement, in fact it was worse, and I said NO MORE!
If you aren't too bored or uninterested we can jump to 2005 when I was 49 Y/O.
BTW, done deal for you on the orthodontia I know, but your teeth look pretty OK to me.
You must have been if nap time is 5 AM!
