What Is Dry Eye?
Other terms used to describe dry eye include dry eye syndrome, dry eye disease, ocular surface disease, chronic dry eye, and dry eyes.
Oddly, dry eye also can cause watery eyes. The watering occurs when irritation caused by dry eye stimulates the lacrimal gland (located behind the upper eyelid) to over-secrete the thin, watery component of a normal tear film.
