One reason for an eye that tears could be lack of oil in the Basal tear film.
The oil, called meibum, is secreted from the meibomian glands in the top and bottom eyelid. The meibum rises to the surface of the tearfilm and leaves a protective coating over the nutrient rich aqueous layer, thus preventing evaporation.
Without this protective coating, the aqueous layer evaporates, leaving dry spots on the cornea. These dry spots may feel like there is something in the eye. The brain receives this signal of irritation and floods the eye with plain water tears to rinse out the “foreign body”, causing the eye to feel wet and drippy.
Unfortunately this does nothing to fix the original problem, the lack of oil in the basal tear film.
If you are experiencing watery eye, schedule an appointment with our eye specialists to determine if treatment could help.
