2. This is how an eye looks like when your looking at a person This is the parts of the eye

3. The eye is used for many things. Many people don’t know the wonders of the eye or how facinating it really is. THE EYE

4. Light is a kind of energy Travels 186,000 miles per second The light that you see from the sun was light that the sun gave out 8 minutes ago When light travels between two places it travels in waves of energy Light (waves) behave in four ways reflection, refraction, diffraction, and interference Christiaan Huygens (1629–1695) said that light was waves Sir Isaac Newton (1642–1727) thought that light was a stream of particles LIGHT

5. These are Sun rays

6. The outer layer of the eye Clear and Transparent Provides about 70% of the eye's refractive power Contains no blood vessels, damaging the cornea can be very painful Has five layers: the epithelium, Bowman's membrane, the stroma, Descement's membrane, and endothelium CORNEA

7. The pupil is a hole in the center of the iris Where the lens is PUPIL

8. Transparent tissue The lens is behind the pupil Lens help to focus images on the retina Lens can change shape by bending to focus on light LENS

9. The iris is the colored part of the eye just behind the cornea Colors can vary between people What is really fascinating about the iris is that it is like a fingerprint The iris pattern is different for every person Not even twins have a same looking iris IRIS The iris

10. Gel-like substance Between the lens and the retina Also keeps the shape of the eye. VITREOUS HUMOR Vitreous Humor

11. Thin layer of tissue that contains nerve cells Cells are responsive to light In the back portion of the eye RETINA

12. They able to make you see black and white Don’t see color React to low light levels ROD CELLS

13. Used for seeing color in bright conditions CONE CELLS

14. Graduated potentials is a signal that passes threw the bipolar cell to get to the ganglion cells Bipolar cells are connected to horizontal cell BIPOLAR CELLS

15. Connected to the Bipolar cells GANGLION CELLS

16. Part of the neuron that transmits nervous impulses Thickness of axons varies Thick axons carry nerve impulses more quickly Covered with a thick layer of the cell's fatty membrane AXONS

17. Branch-like structures on neurons Detect chemical signals DENDRITES

18. Collects nerve impulses Carries them to the brain Interprets them as an image OPTIC NERVE
