1) Lipid layer:
The oil layer and the outer most layer of the tears.
This layer is produced by our meibomian glands.
It helps to prevent our tears from evaporating and also help to spread our tear film evenly across
the surface of the eye.
2) Aqueous layer:
The water layer and the middle layer of the tears.
This layer is produced by our lacrimal glands.It is rich in protein and provides oxygen and nutrients to the front part of our eye, the cornea.
