(Bob/bsee) A guy I used to work with had one eye done. Supposedly the best of both worlds, risk one, fix the bad one, and your brain will eventually adjust and use whichever is appropriate.
The problem he had was that, when driving at night with raindrops on the windshield, he ended up focusing on the raindrops.
I haven't been in touch with him for a few years, so perhaps he's gotten over this (I think I would have heard if he hadn't). But it seems it was quite difficult, and disturbing.
