  4. 4. Tear Film  Lipid Layer (meibomian glands)  Aqueous Layer (lacrimal gland)  Mucus Layer (goblet cells)
  5. 5. Functions Anterior corneal surface smooth & regular for refraction Prevents the drying of cornea & maintain the transparency of cornea Supply oxygen Medium for removal of debris & noxious irritants Lubricates the cornea eye lid interface
