Parts of the eye ball: cornea, pupil, iris, aqueous humor, vitreous humor, retina, blind spot, optic nerve, lens, and the sclera.
Functions of each part:
- Cornea: The protective layer protecting the iris and the pupil. It bend light as it passes through to create an image. This image is then finished off by the lens.
- Pupil: A hole in the iris allowing light to pass through.
- Iris: The colored part of your eye which is a muscle that gets bigger or smaller and controls how much light enters the eye.
- Aqueous humor: This is a water-like liquid that helps the cornea keep its shape.
- Vitreous humor: A jelly like substance that keeps the eye ball round.
- Retina: A layer light-sensitive cells in the back of your eye that focus the image given by the cornea and lens and sends it to the brain via the optic nerve. This is how you identify what image is what.
- Blind spot: A spot where all the nerves in the retina join. There are no light sensitive cells in the blind spot.
- Optic nerve: The bundle nerve that takes the images you see to the brain. This is how you can tell what is what.
- Lens: A convex lens that bends light into a focus point on the retina. The lens can can shape for focusing of images that are far away or closer.
- Sclera: The white tough, thick covering around your eye ball.
