Find out how the eyes and brain work together to help humans see.

How does it work?

  • The human eye is shaped like a ball (a 'sphere').

  • The black spot in the middle is called the pupil.

  • Light travels through the pupil to the back of the eye.

  • The eye sends information about shapes and colours up to the brain.

  • The brain then turns this into a picture so we know what we are looking at!

Why are two eyes better than one?

  • Two eyes are better at helping the brain work out how close or far away things are from us.
