The Mind's Eye, by Oliver Sacks

I read this over the course of a month while eating lunch at work. As always, quite fascinating stories of how the brain and senses interact. This time Sacks discusses vision, primarily because he lost partial vision rather suddenly a few years ago. He's brilliant, but definitely not perfect and quite humble in his explanations of his own and other eye-brain complications. Easy to read and at the same time rather disturbing.
