Description
Source: eyevideofan | http://www.youtube.com/user/eyevideofan | The punctum (puncta) are tiny holes located in the eyelids near the bridge of the nose. Excess tears drain through the punctum, down the canalicular system into the lacrimal sac, then down into the nose. This explains why you get a runny nose when your eyes are watering.
