There was a piece on Mtv about Virtual Reality's affects on vision. They
said that the VR system and reality don't line up perfectly, ie if you grab
something in the Virtual World it may be a bit to the right or left in
the real world. When you stop useing the system your eyes will be
adjusted for the Virtual place. This makes you think things are in the
wrong place in the real world. You need about an hour to adjust back again
before you should drive or use machinery.
