1. Cornea: The transparent, front part of the eye that covers the pupil and iris. It helps to focus light onto the retina.
2. Aqueous humor: A fluid-filled chamber between the cornea and the lens.
3. Pupil: The black opening in the center of the iris. It allows light to enter the eye.
4. Iris: The colored part of the eye that surrounds the pupil. It helps to control the amount of light that enters the eye.
5. Lens: A transparent, flexible structure behind the iris. It changes shape to focus light onto the retina.
6. Vitreous humor: A gel-like substance that fills the main cavity of the eye. It helps to hold the retina in place and provides nutrients to the lens and retina.
7. Retina: The light-sensitive tissue at the back of the eye. It contains specialized cells called photoreceptors that convert light into electrical signals.
8. Optic nerve: A bundle of nerve fibers that carries electrical signals from the retina to the brain.
