Binocular Cue

Binocular Cue

Binocular Cue is a way to view depth.  It is the depth perception we have but requires two eyes to see the depth.

Stereopsis or Disparity
  By using two eyes, your eyes take two different pictures and over lap them allowing you to very accurately tell the distance from one object to another.

This picture is an example of how disparity works. Place your nose on the screen. Relax your eyes. Slowly move your head back and you will see a face. If not, relax your eyes more!
