The ability to perceive visual depth is related to a similar property known as Retinal Disparity.
Retinal disparity is the reality that the left and right fields of vision offer slightly extraordinary visual pics while focusing on a single object. it's far a sort of binocular visual cue that allows humans to perceive depth and distance.
Retinal disparity marks the difference between the two photographs. because the eyes lie multiple inches apart, their retinas select up barely distinctive photographs of objects. The retinal disparity will increase as the eyes get closer to an item.
As an object's distance from the viewer increases, the dimensions of its image at the retina become smaller. And, generally, in the absence of additional visual cues, large objects are perceived as being nearer than smaller items.
