What is a blocked tear duct?

Tears are created in the lacrimal gland and flow across the eye. They drain out through tiny holes, called puncta, on the inside corners of your eyes, near the nose. If the drainage system is blocked, the eye can be watery and irritated. Blocked tear ducts can also cause ongoing eye infections.
