When you blink your eyes, tears spread across the surface of the eye, providing moisture and protection. Excess tears drain through small openings in the corners of the eyelids, called puncta, into the tear ducts. From there, they flow into the nasal cavity, which is why your nose may run when you cry. Ultimately, the tears evaporate or get reabsorbed by the body.
