Let's try doing the following experiment.

What to do：about object at or other small Use string to hang a paper clip ) level.

胸部chest(steps Pick up a stick, such as a broom handle. Take three or four away from the paper clip.

Now close one eye and walk toward the paper clip. Try to touch it with the tip of the

stick. If you miss, try again, still keeping one eye closed. Now try it with both eyes open

and see if it's easier to do.

：How it worksIn the experiment, you have to judge how far away the paper clip is. Your brain has

several ways of doing this.

) itself. Using 聚焦your eye has to focus(One simple way depends on how much

only one eye, most people will find it difficult to touch the paper clip on the first try, but

though not much.

—the brain still gets some information about distanceYour brain can judge distance much better when you look at something with both

eyes. In fact, your brain has more than one way to use both eyes in judging distance. For

example, to see anything clearly, you have to make both of your eyes point at the object.

When you look at a nearby object, your eyes turn inward. You can feel this happening if

you look at the tip of your finger and move your finger toward your nose.
