There is a gland under the upper eyelid, toward the outside edge, called the LACRIMAL GLAND. This produces tears which are spread across the eye with each blink to keep it moist. The tears them drain out through the "tear duct" on the inside corner of the eye, and into the nose. An eye that waters too much can either have an overactive lacrimal gland (which is often the body's way of trying to flush out irritants) or it can be a blocked tear duct, a rather common problem which often requires a physician's help.
