  • Cornea (clear layer over the iris and pupil).

Other important parts of the eye include:

  • Lens
  • Retina (back of the eye)
  • Optic nerve.

Jinsi tunavyoangalia

  • Light enters through the pupil
  • The light passes through the lens, which focuses it on the retina
  • An image is formed on the retina
  • The image is sent to the brain as electrical signals through the optic nerve
