Retinal disparity refers to the different view of the world that each eye receives.
Explanation:
The left eye and the right eye, view images in a slightly different way.
This difference in the view is what is called retinal disparity.
The space between the eyes give a false impression about the details of an object, for example depth.
Due to the space between the eyes, the angle of view of an object differs for the two eyes, and hence different kinds of views aligned to the eye that saw the object.
