Answer:
The labeled drawing is attached; I just grabbed an image off of the internet. You can do this by hand by just copying what's in your textbook or other reference materials. Let me define five main parts:
- <u>Retina.</u> This is a thin layer of tissue on the back of the eye that receives the signals of light and transfers them to the brain so you can understand them as color and sight.
- <u>Cornea.</u> This is the front part, a reflective layer that "refracts" light. What this means is that light doesn't go directly through it, but its path is almost deflected a little.
- <u>Sclera.</u> This is the part that looks white from the front. It's a protein covering to your eye, and it's very close to the cornea.
- <u>Iris.</u> This is the actually colored part of your eye. If you have hazel or blue eyes, the iris is that portion of the eye. It allows differing amounts of light in.
- <u>Pupil.</u> This is the black part of the eye. It's a hole that looks black because of all the light coming through and being absorbed.
