deinonychus commented on the word basal tears
There are three very basic types of tears: basal tears, reflex tears and crying or weeping (psychic 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. (Wikipedia)
