Pupil - hole allowing light into eye.

Sclera - White of eyeball

Aqueous and vitreous humour - fluid in eye

Answer 2

The white part of the eye is called the sclera. The colored circle in your eye is called the iris. The black spot in your eye is called the pupil. The pupil is actually a hole that gets bigger in the dark so it lets more light in. It gets smaller in the light so it could keep less light out of the eye.

Answer 3

The main parts of the eye include the cornea, iris, pupil, lens, retina, and optic nerve. The cornea helps to focus light onto the retina, while the iris regulates the size of the pupil to control the amount of light entering the eye. The lens helps to further focus the light onto the retina, where photoreceptor cells convert light into electrical signals that are sent via the optic nerve to the brain for interpretation.
