Abstract:

Shifts in the apparent size and distance of real objects viewed binocularly and monocularly and of objects viewed indirectly through imaging displays are accompanied by shifts in visual accommodation distance. It is hypothesized that relaxation of accommodation toward the intermediate resting position in the absence of adequate textural cues to distance attenuates the size of the projected retinal image of more distant objects, thereby causing reductions in apparent size or increases in apparent distance, including certain types of optical illusions.
