940 - How do our eyes work to help us see?

Your eyes are like two tiny cameras that help you see the world. Here's how they work:

  1. Light enters: When light from something (like a ball or a tree) hits your eyes, it goes through a window called the CORNEA.
  2. Light bends: The light bends and passes through a jelly-like part called the LENS. The lens changes shape to focus the light, like a camera lens.
  3. Light hits the retina: The light lands on the RETINA, which has special light-sensitive cells called RODS and CONES.
  4. Signals to the brain: These cells send signals to the brain, which combines the signals to create a picture of what you're seeing.
  5. You see: Your brain says, "Ah! I see a ball!" or "I see a tree!" And you can see it too.

It's like a tiny camera taking pictures and sending them to your brain, so you can see the world around you!
