(Experimento: ¿Dos ojos son mejores que uno?) How two eyes give
you more depth perception, which is the ability to judge how
near or far objects are. - Hold a pencil lengthwise (on its
side) in each hand. - Now, with one eye closed, try to touch the
erasers together. Did you miss? - Now, try it with both eyes
open. Voila! Two eyes give you better depth perception. Reviewed
