DISCUSSION. Tears flow from tear glands into your eyes through tiny tear ducts. The tear glands are located under your upper lids, and when stimulated, produce tears to form a thin film over your eyeballs.Every time you blink the film spreads over your eyes to keep them moist and free of dust and other irritants.he tear glands are located under your upper lids, and when stimulated, produce tears to form a thin film over your eyeballs.

To make room for new tears, the fluid drains out of your eyes through small holes, called puncta, in the corners of your upper and lower eyelids. Then it drains through the nasolacrimal sac into the tear duct (lacrimal duct) and into the back of your nose. Infections are usually caused by a blockage in the lacrimal duct that allows bacteria to build up inside the tear sac. An infection that starts suddenly is called acute dacryocystitis.
