My first VR experience playing Heavy Metal at the Troc in Piccadilly,
London, was completely marred by this problem. I could barely see what
was going on, most images were out of focus and I experienced double-
vision for most of the game. I was totally surprised by this, as I assumed
that VR would have these problems licked before they went commercial with 
it.
