CEVAP:

The two-dimensional image in the retina is perceived as three-dimensional with the deductions about depth or cues about distance. This is done by only one-eye (monocular) and two-eye (binocular) depth cues. Distance perception is the act of knowing or recognizing of a distance by previous experiences or recollective thought. Depth and distance perception refers to the ability to recognize objects by positioning them in variable distances in a three-dimensional world.
