What are tears made of?
Tears consist of water, oil mucus and salt.
The Importance of Tear Film
Every time you blink, a thin layer of tears called “tear film” is spread across the outer layer of the eye. Tear film can help the eyes in many ways, including keeping the eyes hydrated to provide clear, crisp vision. It also can help clean and protect your eyes.
Tear film is made up of two different layers:
Oily layer
The outer layer of tear film, known as the lipid layer, which keeps tears from evaporating too quickly and makes the surface of the eyes smooth.
Watery/mucus layer
The layer of tear film closest to the eye, known as the mucoaqueous complex layer, helps the tear film stick to the surface of the eyes and keeps them hydrated.
