This happens when the lacrimal glands make enough salt-watery fluid to cover the eye, but the meibomian glands do not make enough oils. The surface of the eye actually dries out between blinks. This makes the eye irritated, and the lacrimal glands make even more fluid. But this fluid just overflows from the eye instead of keeping it wet.
This is one form of epiphora, which is the medical term for the condition of overflowing tears. There are several other possible causes of epiphora. The lacrimal glands might be making too much fluid because the eye is irritated by wind, bright light, dust or allergies.
The other causes of epiphora are related to problems with the drainage system of the eye. There are small openings inside the edges of the eyelids near the nose. Each upper and lower eyelid has one of these openings, called a punctum.
These four openings, or puncta, act like little valves to take tears out of the eye. Each time we blink, some tear fluid is pumped out of the eye through the puncta.
If some or all of the puncta are blocked, tears will overflow. The puncta are tiny, so they can be blocked by small particles of dirt or even loose cells from the skin around the eye. Sometimes an infection near the puncta will make the area swollen, and the puncta will not work properly. Any of these things can cause epiphora. After the tears leave the eye through the puncta, they drain down through a little "tube" called the nasolacrimal duct.
This duct goes underneath the skin and through the bones of the face into the nose.
Normally, there is so little tear fluid that the nose does not get very wet. The connection between the eye and the nose is obvious, however, when someone is crying. Even when the puncta are open and working well, the nasolacrimal duct can be blocked. Not only will this cause problems with tear drainage, it usually has other symptoms too, including:.

If the nasolacrimal duct is blocked, it can become infected. This is called dacryocystitis, and it can become very uncomfortable.
