Question

Instead of studying, you decide to go to a movie theater to see the latest release of a 3D movie. The movie starts and you see some parts of a scene closer than others. This effect is achieved using slight variations in the position of corresponding objects in the two eyes. This variation in retinal position is called _________.

Answer 1

This variation in retinal position is called binocular disparity.

What is binocular disparity?

The little variation between the images on the right and left retinas. Each retina receives a slightly different image when both eyes are focused on the same object because of the disparity in visual angles caused by the eyes' various positions.

The two images are automatically compared and, in the event that they are sufficiently comparable, they are merged, serving as an essential indication of depth perception. It is also known as retinal disparity.
