The lacrimal gland and other small glands located inside the eyelid and on the white part of the eye constantly produce tears to keep the eye moist, lubricated and healthy.
HOW DO TEARS DRAIN FROM THE EYE?
Tears are produced by glands around the eye and are washed across the eye towards the nose. They drain from the eye though two small openings called the upper and lower puncta, which are located at the inside corner of the upper and lower eyelids near the nose.
