How the Eye Works

Describe how the eye works: light enters through the pupil, the lens focuses it onto the retina at the back of the eye, and the retina sends signals along the optic nerve to the brain, which interprets the image

How to tell they’ve got it

Tick these off as you see them — no test required.

Name the main parts: pupil (lets light in), lens (focuses light), retina (detects light), optic nerve (sends signals to brain)
Describe the sequence: light enters → lens focuses → retina detects → nerve signals brain → brain interprets image
Explain that the pupil gets bigger in dim light and smaller in bright light to control how much light enters

Try this together

Can your child explain what happens inside their eye when they look at something — how light comes in through the pupil and the brain turns it into a picture?
