The eye has a number of other key components including: the cornea, the pupil, the lens, the retina, the macula, the optic nerve, and the vitreous.

  • The cornea is the clear front window of the eye that transmits and focuses light into the eye.
  • The pupil is the dark aperture in the iris that determines how much light is let into the eye.
  • The lens is the transparent structure inside the eye that focuses light rays onto the retina.
  • The retina is the nerve layer that lines the back of the eye, senses light and creates impulses that travel through the optic nerve to the brain.
  • The macula is a small area in the retina that contains special light-sensitive cells and allows us to see fine details clearly.
  • The optic nerve is the nerve that connects the eye to the brain and carries the impulses formed by the retina to the visual cortex of the brain.
  • The vitreous humor is a clear, jelly-like substance that fills the middle of the eye.
