Which type of tears are produced when the eyes are exposed to irritants?

Reflex tears are produced in response to irritants that come into contact with the eyes, such as smoke, onions, or foreign objects. These tears are generated by the lacrimal glands to help flush out the irritants, provide moisture, and protect the surface of the eye. This rapid response serves an important function in maintaining eye health by reducing discomfort and preventing potential damage from the irritants.

In contrast, basal tears are produced continuously to keep the eyes lubricated and nourished. Emotional tears are associated with feelings and are often generated in response to strong emotions like sadness or joy. Stable tears is not a recognized term in the context of tear types, making it an irrelevant choice. Thus, reflex tears are the correct answer, highlighting their role in eye protection and reflexive response to irritants.
