  1. Dissection

  2. Parts of the Eye • Aqueous humor: A clear fluid that helps the cornea keep its rounded shape • Blind Spot: The place where all nerves from the retina join to form the optic nerve. There is no light sensitive cells here. • Cornea: Tough, clear covering over the iris and the pupil that helps protect the eye.

  3. Cornea: Covering on the front of the eye. Helps protect the eye Sclera: The tough outer covering of the eyeball

  4. Lens: • Clear, flexible structure that makes an image on the eye’s retina. It is flexible to change shape to focus on close and far objects

  5. Optic Nerve • Bundles of nerve fibers that carry information from the retina to the brain. • Retina: The layer of light sensitive cells at the back of the eye. Detects images focused by the cornea and lens.

  6. Tapetum: colorful shiny material located behind the retina. Found in animals with night vision. It reflects light back through the retina • Vitreous Humor: The thick jelly that helps give the eyeball its shape.
