Primary project from the eye

1. HOW DOES THE EYE WORK?

2. CORNEA
RETINA
LENS
IRIS
PUPIL
RETINA
OPTICAL
NERVE

3. 1. Light enters the
cornea and the pupil.
The cornea protects
the pupil and the
pupil controls how
much light enters the
eye.

4. 2. The iris gives colour
to the eye.

5. 3. Next, light goes to the lens. The lens
focuses the light and makes and image.

6. 4. The image is refracted onto the
retina...

7. And then it goes to the optical nerve.

8. 5. The optical nerve sends the image
(information) to the brain.

9. The brain interprets this information
and then sends a message to the
locomotor system.
