The lack of depth perception of people who are blind on one eye has been
greatly exaggerated. People with only one seeing eye have a surprisingly
good depth perception.
And that doesn't take years. It takes just a minute or so. You can test
it yourself, and it's actually quite awesome. For instance, watch a 3D game
of even a movie with one eye (cover your other eye with something). In a
few tens of seconds you will start seeing the game with depth perception.
It will start looking truly three-dimensional (not *exactly* as well as
a real three-dimensional scene looked with both eyes, but almost).
The reason is that the brain is really good at compensating for the lack
of stereoscopic view, and will start to use secondary clues to form a
perception of depth.
