Abstract
The preocular tear film is composed of an aqueous phase containing mucins and dissolved proteins and a thin external lipid layer. The lipid layer slows aqueous evaporation and protects the ocular surface from environmental irritants. The lacrimal glands supply the bulk of the ocular tear fluid phase, as well as many dissolved proteins. The meibomian glands of the eyelid secrete the lipids. Harderian glands of non-primate vertebrates secrete proteins and lipids.
