Tear-related issues refer to problems with the production, quality, or drainage of tears, which are essential for keeping the eyes lubricated, protecting against infection, and maintaining clear vision. Common problems include dry eye, in which tear production is insufficient or tears evaporate too quickly; excessive tearing (epiphora), which can result from blocked tear ducts, irritation, or infection; and changes in tear composition that reduce effectiveness. Symptoms may include burning, stinging, redness, a gritty or foreign body sensation, blurred vision, watery eyes, or recurrent eye infections. Tear problems can arise from aging, environmental factors, medications, autoimmune conditions, or structural abnormalities of the eyelids or tear ducts. Persistent or severe symptoms should be evaluated to identify the underlying cause and prevent complications.
