TEAR FILM

The tear film is traditionally described as having three layers:

The outer lipid layer
The middle aqueous layer
The mucous layer, which borders on the cornea

The lipid layer is the superficial oily layer of the tear film that is in direct contact with ambient air. These lipids are mainly secreted by the meibomian glands.
