Adaptation to three-dimensional distortions in human vision.

Abstract

When people get new glasses, they often experience distortions in the apparent three-dimensional layout of the environment; the distortions fade away in a week or so. Here we asked observers to wear a horizontal magnifier in front of one eye for several days, causing them to initially perceive large three-dimensional distortions. We found that adaptation to the magnifier was not caused by changes in the weights given to disparity and texture, or by monocular adaptation, but rather by a change in the mapping between retinal disparity and perceived slant.
