Question

Quizplus · Accepted Answer

Retinal disparity refers to the difference between the images received by each retina due to the slightly different perspectives of the eyes. This difference is greater when an object is closer, causing the eyes to have to converge more, resulting in the perception of depth and three-dimensional vision. When an object appears to jump back and forth when viewed with each eye, it is due to retinal disparity. Therefore, the phenomenon described in the question is an example of retinal disparity.
