home work:

Cornea: The transparent front part of the eye that covers the iris and pupil. It helps focus light into the eye.

Iris: The colored part of the eye that regulates the amount of light entering the eye by adjusting the size of the pupil.

Pupil: The black circular opening in the center of the iris that allows light to enter the eye.

Lens: Behind the iris, the lens helps focus light onto the retina. It can change its shape to adjust the eye's focus.

Retina: The innermost layer at the back of the eye that contains light-sensitive cells (rods and cones). It converts light into electrical signals that are sent to the brain through the optic nerve.

Optic Nerve: A bundle of nerve fibers that carries visual information from the retina to the brain.

Vitreous Humor: The clear, gel-like substance that fills the space between the lens and the retina, helping to maintain the eye's shape.

Sclera: The white, tough outer layer of the eye that helps protect and maintain the eye's shape.

Choroid: A layer of blood vessels between the retina and the sclera that nourishes the retina.

Ciliary Muscle: The muscle that controls the shape of the lens, allowing the eye to focus on objects at different distances.
