Dry eyes and tearing
This is a chronic disease of the tears and the eye surface, and may be caused by a variety of factors, including hormonal change, age, viewing or occupational habits, ocular surgery, certain ocular and systemic diseases and medications, as well as Meibomian gland disease.
Watery eyes in dry eye condition may be due to reflex tearing. The tear properties under basal conditions may be altered in dry dye so that there is insufficient protection of the ocular surface, resulting in irritation and reflex tearing.
