Which of the following allows a person with vision in only one eye to perceive depth?

Retinal disparity is a binocular cue for depth perception that occurs due to the slight difference in the images received by each eye. This comparison between the two slightly different perspectives allows for the perception of depth. Since a person with vision in only one eye lacks this binocular input, retinal disparity cannot contribute to their depth perception.

Stereopsis is the perception of depth that arises from both eyes working together. It relies on the brain's ability to fuse the two slightly different images from each eye into a single three-dimensional view. A person with vision in only one eye cannot utilize stereopsis, as it fundamentally depends on input from both eyes.

Convergence refers to the inward movement of both eyes towards each other when focusing on a close object. This cue is primarily effective for depth perception in individuals with binocular vision, as it provides information about how far apart the eyes are when viewing an object. Therefore, it does not apply to someone with vision in only one eye.

Lateral inhibition is a process in the retina that enhances contrast by allowing stimulated photoreceptor cells to inhibit their neighbors. While it plays a role in visual processing, it does not directly contribute to depth perception, especially for individuals with vision in only one eye.
