What symptom is typically associated with epiphora?

Epiphora is a condition characterized by excessive tearing. This symptom occurs when the tear production exceeds the drainage capability of the lacrimal system, often leading to a constant overflow of tears. It can be caused by various factors, such as an obstruction in the tear ducts or irritation of the ocular surface, which triggers an overproduction of tears. In the context of the options provided, excessive tearing is the hallmark symptom, as it directly defines the condition of epiphora.

The other choices, while related to eye health, do not accurately represent epiphora. For example, dry eyes result from insufficient tear production, which is the opposite of what is seen in epiphora. Vision loss can stem from numerous eye conditions but is not specifically linked to epiphora. Similarly, red eyes can occur due to various factors like inflammation or allergy but are not characteristic of epiphora.
