I imagine for someone who, say, lost an eye at 25, driving would be really difficult

I lost useful vision in my left eye (some kind of lump arose behind the retina, it distorts the left eye vision into funhouse-like wavers, plus some rotation) when I was 50. I'm nearly 60 now. There are a few small issues, but generally speaking I adapted quickly. I found that my knowledge of the general and relative size of things like cars and so forth pretty much gives me a solid "near-enough" guide so that I can manage just fine. I don't even see the trash my left eye feeds me any more unless I close my right eye and really think about it.

I've been sort of turning it over in the back of my mind since I saw your post, and I think I've identified the thing that gave me the most trouble; it was pouring wine. I have a heck of a time telling if the wine bottle is over the glass. So I compensate by using the side of my hand to locate the distance of the glass from me, then pull pack, and "tink" touch the bottle neck to the glass before I pour. Completely different approach than what I could do with both eyes, which was aim visually, pour, done.

I can't catch anything that's thrown anymore, either. Doesn't get in my way, I just make sure people don't throw things at me. :)
