Which of the following is NOT a symptom of bacterial conjunctivitis?

Bacterial conjunctivitis is typically characterized by symptoms that include a sore, swollen eye, and the presence of a purulent (pus-like) discharge, which is often yellow in color. Symptoms also frequently include photophobia, or sensitivity to light, due to irritation of the conjunctiva.

Watery discharge, while it can occur with other types of conjunctivitis, such as viral conjunctivitis or allergic conjunctivitis, is not commonly associated with bacterial conjunctivitis. Instead, bacterial conjunctivitis usually presents with thicker, yellowish discharge that accumulates and causes the eyelids to stick together. Therefore, watery discharge is not indicative of this bacterial infection, making it the correct answer as it is not a symptom associated with bacterial conjunctivitis.
