Basal tears. In healthy mammalian eyes, the cornea is continually kept wet and nourished by basal tears. They lubricate the eye, and help to keep it clear of dust. Tear fluid contains water, mucin, lipids, lysozyme, lactoferrin, lipocalin, lacritin, immunoglobulins, glucose, urea, sodium, and potassium.lso, emotional tears are made up of a different chemical component than those evoked by eye irritants and can relay chemical messages to others. The change in sex drive could be attributed to a drop in testosterone provoked by the tear chemicals, reducing aggression.
The tear film is kept stable by mucin which is secreted by a thin membrane covering the front of the eye, called the conjunctiva. Dry eyes result from a reduced production of tears, a reduced production of mucin by the conjunctiva, or increased evaporation of tears from the surface of the eye.
