The stuff I\'ve read said your brain did reorient the image. I remember reading that after the \'inverting\' glasses were removed after a few days, it didn\'t take long for the view to correct back to normal due to the way it is used to seeing.
This doesn\'t surprise me at all, given that the image on the retinas is actually upside down, and the brain in early development eventually figures out the correct orientation.
I believe that if you consider the orientation of the brain itself, functionally speaking it is upside down, with the left side controlling or processing inputs from the right and vice versa. \"The left hemisphere visual cortex receives signals from the right visual field and the right visual cortex from the left visual field.\" http://en.wikipedia.org/wiki/Visual_cortex
Seems to me that we are hard-wired to invert the images on our retinas.
I don\'t really see an advantage of the visual system having the ability to make an inverted view (by prism glasses) upright again. Up and down are relative anyway and if the motor systems can adapt to it there isn\'t a problem really.
I\'ll see if I can find the source that convinced me, but I feel that the wikipedia article is possibly incorrect.
Edit: Here\'s one experiment that seems to refute the idea that the brain can make the image upright again: click
