A human eye has two tear ducts, also known as lacrimal ducts. Each eye has a superior and inferior punctum, which are small openings that allow tears to drain from the eye into the nasolacrimal duct and eventually into the nasal cavity. Therefore, with both eyes, there are a total of four tear ducts.
The tear ducts are called the lacrimal ducts. The duct that drains the tears from your eye (located in the nasal corner of the eye) is called the nasolacrimal duct.

The lacrimal ducts allow tears produced by the lacrimal glands to pass from the eye to the nasal cavity, where they drain into the nasolacrimal duct. This drainage system helps to keep the eye moist and maintain a healthy tear film on the surface of the eye.
