Meghna Thapar 5 years, 6 months ago

The various parts of the human eye and their respective functions include:

  1. Cornea – It helps the light to enter the eyes coming through various objects.
  2. Iris – It controls the amount of light entering in to the eyes.
  3. Pupil – It is a hole in middle of iris which adjusts its opening to allow the required amount of light for clearing purpose.
  4. Ciliary muscles- The focal length of the eyes is changed by the action of ciliary muscles. The ciliary muscles can change the thickness of the soft and flexible eyes lens and hence the focal length which, in turn, changes the converging power of the eyes.
  5. Eye-lens – It forms the real image of the object on the retina.
  6. Retina – It is a screen on which the image is formed.
  7. Optic nerve – These nerves transfers the formed image to the brain.
