    Answer:

The eye contains following parts:

  • Vitreous gel: a clear gel that fills the inside of the eye.
  • Optic nerve: a bundle of more than one million nerve fibers that carries visual messages from the retina to the brain.
  • Macula: the small sensitive area of the retina that gives central vision. It is located in the center of the retina and contains the fovea.
  • Fovea: the center of the macula and gives the sharpest vision.
  • Retina: the light-sensitive tissue lining at the back of the eye. The retina converts light into electrical impulses that are sent to the brain through the optic nerve.
  • Iris: the colored part of the eye that regulates the amount of light entering the eye.
  • Cornea: the clear outer part of the eye's focusing system located at the front of the eye.
  • Pupil: the opening at the center of the iris. The iris adjusts the size of the pupil and controls the amount of light that can enter the eye.
  • Lens: a clear part of the eye behind the iris that helps to focus light, or an image, on the retina.
