Psychology -> Binocular depth cue

Binocular depth cue

In 'magic eye' pictures each eye observes a slightly different view of the same scene.

Retinal Disparity (Binocular Disparity): A primary binocular depth cue which is caused by the fact that our eyes are 6-7cms apart and thus receive slightly different retinal images. The difference in locations of the images on each eye provides a powerful cue to distance. The brain fuses the two retinal images together to provide us with stereoscopic vision. For example, in 'magic eye' pictures, each eye observes a slightly different view of the same scene and the brain fuses the two images together to create a three-dimensional picture.

Convergence: A primary binocular depth cue where the eyes turn inward to focus on an object so that a single image is formed on both retinas. The closer the object, the greater the convergence. For example, the eyes converge when catching a ball.
