The retina: has got a thin layer of optic cells that detect light and colours. These optic cells send information to the optic nerve. Interior The cornea: is a transparent layer of cells.

  5. How the eye works • Light goes into the eye through the pupil. Then it passes through the lens. • The lens projects an upside down image onto the retina.

Finaly, the brain interprets the impulses. It also turns the image the right way up again. Go back
