  • How Do You See?


    • First, light bounces off objects all around you and enters your eye.
    • Then the light passes through your pupil and lens to the retina at the back of your eye.

    • The retina contains light sensitive cells called rods and cones that change the picture into nerve signals, these are passed through more cells and finally to the optic nerve.

    • The optic nerve carries the nerve signals to your brain.

    • Finally, your brain reads the signals and tells you what you're seeing.
