According to the mode of production, tears are classified into four types: basal, closed eye, emotional, and reflex. The basal rate of tear secretion is ~0.5–2.2 μL/min, and irritation can increase secretion by up to ~100-fold, reaching ~300 μL/min. Tears are made up of water, electrolytes, proteins, lipids, and mucins that form layers on the surface of eyes. The four types of tears differ significantly in their composition. upr

Certain bees, butterflies, and flies have been observed feeding on the tears of reptiles, birds, and mammals, including humans. Lachryphagous insects gather nutrients, especially sodium and proteins, from the tears. Lachryphagous feeding can be unbothersome or painful, with some feeding insects damaging the eye and introducing pathogens to the host. Lachryphagy has been studied as a form of parasitism, commensalism, and puddling.
