What is a common issue that occurs when there is a buildup of lacrimal fluid?

When there is a buildup of lacrimal fluid, the common issue that arises is watery eyes, often a result of the body's natural response to irritation or blockage in the tear drainage system. This condition, known as epiphora, occurs when tears are produced normally but cannot drain away effectively through the nasolacrimal duct. Consequently, tears overflow onto the surface of the eye and spill onto the cheeks, making the eyes appear excessively watery.

This situation can be triggered by various factors, including allergies, infections, or anatomical abnormalities that obstruct the tear drainage system. The body's effort to clear irritants can lead to increased tear production, compounding the problem when drainage is compromised, and resulting in the sensation and appearance of watery eyes.
