Layers of the tear film. The human tear film is composed of 3 layers: mucin, aqueous, and lipid. Each layer has a distinct function in maintaining good tear quality and preventing tear evaporation. When one layer becomes deficient, the symptoms of dry eye appear. Depending on which layer of the tear film is deficient, treatment methods will vary. Sometimes there is more than one layer affected.
