Question

1.  Hold 2 quarters (one in each hand) at about an arm’s length from your body.  Close one eye and try to touch the quarters together keeping both hands in constant motion while approaching.  Repeat with both eyes open.  Did you notice any difference in the two conditions and if so why?

Answer 1

Yes it was different in both the cases.It is an example of depth perception.Binocular vision helps us see things better whereas monocular vision has no overlap between the two visual fields of eyes.

Monocular vision presents the world in three dimensions by offering better depth perception. This is because of stereopsis in which the eyeballs converge to present a wider picture.

In this case,seeing the quarter come closer with one eyes leads to person to be unable to decipher the accurate distance or depth between the two objects.This is because we are better able to function and operate using binocular vision.

Whereas with both eyes open,it was easy to know when the quarters touched due to binocular depth perception
