When I was about five or six years old, the school nurse recommended I see an optometrist, subsequently resulting in a "lazy eye" diagnosis and directions to wear glasses for reading, etc. My right eye was affected - my left eye was not affected at all, so the lens on that side had no prescription - and I was told that in time, the issue would correct itself. In my teen years at some point, I suppose, I started wearing my glasses more sporadically or not at all, and I haven't been to the optometrist since those years. When I was 16, I remember having a particularly bad upper respiratory infection - maybe sinusitis - that blew up my eyelids pretty badly. Compresses did little under the circumstances, and I'm not sure my right eyelid ever returned to its previous size since. It's slightly longer than my left one, the crease above it a slight bit higher. And it folds a bit differently. It just looks thick. My right eye still veers off to the side as does a lazy eye.
Also, I am 23 now, and I have heterochromia. And as I do a lot of work with a computer, and a lot of paperwork/homework, I have begun to wear reading glasses. I notice that I hold the muscles in my face strangely to achieve a sort of forced symmetry of my eyelids. It's not horrible, but I feel very unattractive due to this at times. Which of the choices posed in my question would you attribute the asymmetry of my eyelids to?
