- 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.
