Refractive errors affect the vividness of visual mental images.

Refractive errors affect the vividness of visual mental images.

The hypothesis that visual perception and mental imagery are equivalent has never been explored in individuals with vision defects not preventing the visual perception of the world, such as refractive errors. Refractive error (i.e., myopia, hyperopia or astigmatism) is a condition where the refracti...
