Oliver Sacks did end up with vision in only one eye and in his book (http://www.oliversacks.com/books/the-minds-eye/) he describes this experience and its effect on him. How any one individual would experience vision with only one eye, would vary depending on the age at which that vision was lost, and how the brain adapted to monocular vision.

I mention this as there seems to be a question on my dashboard, though it has not appeared elsewhere in the blog. If you are interested, do visit Oliver Sack’s website and The Mind’s Eye is a great read.
