  • The Eye
    • Our eyes give us these features: shape, size, texture, colour and distance from us.
    • Light reflected from an object forms an image on the retina.
    • It has two light-sensitive cells: the rods and the cones.
      • The rods are light-sensitive cells that respond even in dim light. They detect light.
      • The cones are light-sensitive cells that can detect colour. They only work in bright light.
    • The optic nerve is a bundle of nerve cells that leads out from the retina at the back of the eye. It carries information from the rods and cones to the brain.
    • The retina is a light-sensitive layer at the back of the eye. It is made up of two light-sensitive cells (or nerve cells) called rods and cones.
    • Perception is the way the brain makes sense of the visual image detected by the eyes.
