Question

Quizplus · Accepted Answer

Retinal disparity is the slight difference between the viewpoints of the two eyes, which allows for stereoscopic vision and depth perception. Larry, who was born blind in one eye, would not have this disparity and therefore would not be able to utilize it for depth perception. Mary's color blindness would not affect her ability to perceive depth using retinal disparity, and premature birth or reduced acuity may affect depth perception but not specifically the use of retinal disparity.
