I have a friend living a few streets away, he is legally blind and cannot really see too well, if at all, sometimes. I shudder when seeing him ride a pushbike on the roads, although he looks like a disaster waiting to happen, he has managed to miss some really big and small things on roads and streets over the decades I have known him.
He uses Nikon film cameras with auto-focus and tripod, he is a remarkably good photographer and enlarges all of his own films in his own darkroom. Unfortunately he cannot use a computer, but as he is in his seventies and having never used computers, he is not likely, if ever, going to be using them.
Mick.
