convergence and retinal disparity
|
Detailed explanation-1: -There are two types of binocular depth cues: convergence and retinal disparity. Convergence uses both eyes to focus on the same object. As an object moves close, the eyes come closer together to focus. As the eye look at an object further away, the eyes move further apart to focus.
Detailed explanation-2: -Retinal disparity increases as the eyes get closer to an object. The brain uses retinal disparity to estimate the distance between the viewer and the object being viewed. Convergence is when the eyes turn inward to look at an object close up.
Detailed explanation-3: -Retinal disparity is a binocular cue used to perceive depth between two near objects. It does so by comparing the different images from both retinas. Each eye receives different images because they are usually around two and half inches apart.
Detailed explanation-4: -If you hold your finger out at arm’s length and then look at it alternately with your left eye only and then your right eye only, the image of your finger relative to the world behind it will shift somewhat. This is binocular disparity, which helps provide the basis for the determination of depth.
