And you compare the location, at which information about light lands on the two eyes. So your eyes are slightly offset from one another. So that, for instance, if I look at you, if you were standing right in front of me right now, and I were to look at you, the image of your face, the light bouncing off your face to be more precise, lands on one eye in a slightly different location than it does in the other eye, and then the brain does math.
