The Tear Film Composed of Three Layers

Caption

The tear film is composed of three basic layers: mucin (Glycocalyx), water (Aqueous) and lipids, the latter of which helps prevent water evaporation from the ocular surface and protects against infection. (Sassa T., et al, FASEB Journal, Jan. 17, 2018)
