Re: How much eye functionality does this require?
Hi Dave 126 and 1980s_coder
Thanks for your comments. When I first posted it was quite urgent, because we were just setting off to visit the surgeon to see about getting a glass eye fitted (actually they're usually plastic nowadays). Well, we've just got back. As it turned out, the surgeon decided on a conservative approach. He's going to fit a prosthetic front to the existing eyeball, a bit like a big contact lens. That's good, because it doesn't burn any bridges - the existing eyeball (what's left of it) is left undisturbed, hopefully awaiting some new magical electronic prosthesis in the future. She just needs a minor operation to repair the eyelid, to make sure the prosthesis doesn't fall out. She runs a restaurant, so it can be a bit disconcerting if that sort of thing happens in front of a customer (especially if it lands in their meal)!
Can I just add a comment about ladder safety? Falling 10 feet head-first onto concrete (which is what she did) is a life-changing experience. You can lose a lot more than just one eye!
