"Determined to find results, Stratton wore the telescoping glasses for eight days straight. By day four, his vision was upright (not inverted). However on day five, images appeared upright until he concentrated on them; then they became inverted again. By having to concentrate on his vision to turn it upside down again, especially when he knew images were hitting his retinas in the opposite orientation as normal, Stratton deduced his brain had reprocessed his vision and adapted to the changes in vision."
So perceptual adaptation is real, it just takes like a week to really kick in. For someone who had been wearing these glasses for years, I'm sure the effects would be much more intense.
EDIT: The paper that the follow up results were in might actually be "Stratton, G. (1897). Upright vision and the retinal image. Psychological Review, 4, 182-187"
I admit I'm not used to citing academic papers, I heard about this experiment back in high school anth/soc/psych so I just did my best to find a semi-credible reference.
