Anatomy
Tear Film (Lacrimal Film / Tear Layers)
Your tear film is a thin, layered coating that covers your eye. It has three layers: oil (lipid), water (aqueous), and mucus (mucin). Each layer serves an important purpose. A healthy tear film keeps your eyes comfortable, clear, and protected from infection.
