  1. Liquid Iris lens Heavy cone concentration Pupil Cornea Blind spot Muscle Retina Optic Nerve

  2. Corena • Clear outer covering on eyeball • If you look in the mirror and see your eyes shinny. It is the liquid that your cornea contains.

  3. Iris • Colored circular muscle • Opens and closes to control amount of light entering your eye.

  4. Lens • Like camera lens • Helps you focus objects you see onto the back of the eye where there are receptors. • If it is not shaped correctly it will miss the receptors and cause the image to be blurry.

  5. Pupil • The black circle in the center of your iris. • A hole, which is just an opening that allows the iris to change sizes. • It just looks black because it is dark inside your eye. • It just lets light into your eye.

  6. Retina • The back of your eye • Contains millions of light receptors. • There are receptors to the right and left of the optic nerve

  7. Muscle • Tights and loosen, depends on amount of light, to cover or uncover the lens • Part of the iris

  8. Optic Nerve • Transmits information from the visual information from the retina to the brain

  9. Blind Spot • This is the spot where the optic nerve starts. • There are no receptors at this point. • You can not see anything when light waves hit this spot.
