Eye Anatomy

  1. Cornea: The transparent, dome-shaped outer surface that covers the front of the eye. It helps in focusing light.

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

  3. Iris: The colored part of the eye that surrounds the pupil. It controls the size of the pupil and hence regulates the amount of light entering the eye.

  4. Lens: Behind the iris, the lens focuses light onto the retina. It adjusts its shape to allow the eye to focus on objects at different distances.

  5. Retina: The innermost layer at the back of the eye. It contains photoreceptor cells—rods and cones—that convert light into electrical signals and send them to the brain through the optic nerve.

  6. Optic Nerve: A bundle of nerve fibers that carries visual information from the retina to the brain, where it is interpreted.

  7. Vitreous Humor: A gel-like substance that fills the space between the lens and the retina, helping the eye maintain its round shape.

  8. Sclera: The white, tough outer layer of the eye that protects the eyeball.

  9. Choroid: A layer between the retina and the sclera that contains blood vessels, providing nourishment to the eye.

  10. Ciliary Body: Produces the aqueous humor (fluid) that nourishes the cornea and lens and helps maintain the shape of the eye.

  11. Aqueous Humor: A clear fluid that fills the space between the lens and the cornea, providing nutrients to these parts of the eye and maintaining their shape.
