Thank you so very much for your answer.

My blind eye follows my working eye, but is noticeably smaller due to its misuse. So you’re probably right on the money there.

I’m a healthy and active nonsmoker, and intend to remain so! I suppose the dream of magically seeing with my right eye has never been more than that, but I can’t help be a tiny bit hopeful when I see news like this.

If your blind eye is smaller, it's called phthisis, meaning it shrank because the blood supply to the useless organ has effectively been irreversibly shut off (oversimplification). Even if the brain connections could be made, it still wouldn't be able to see because it will never have enough blood supply. You'd probably need a full eye transplant, and by the time we manage to do that, we can practically do full head transplants.

Really great progress they're making in the science though. It's a shame, about your misfortune.

My wife might quite like me having a full head transplant at times.

But, yes, my blind eye is smaller, tender to the touch (specifically on the side), has a pretty severe cataract and astigmatism. So your Reddit-diagnosis is probably right on the money. Thank you for your knowledge!
