What is a common symptom of viral conjunctivitis?

Viral conjunctivitis is characterized by several symptoms, with watery discharge being one of the most common. This condition occurs due to inflammation of the conjunctiva, often caused by viral infections such as adenoviruses. The inflammatory response leads to increased tear production, resulting in a clear, watery discharge that distinguishes it from other types of conjunctivitis, such as bacterial conjunctivitis, which typically presents with a thicker, purulent discharge.

Symptoms such as bloody discharge, sharp eye pain, and vision loss are not typical for viral conjunctivitis. Bloody discharge may suggest a more severe underlying condition, sharp pain could indicate issues like corneal problems or acute glaucoma, and vision loss is generally associated with more serious eye conditions. Thus, the presence of watery discharge aligns with the hallmark signs of viral conjunctivitis, confirming its role as the correct answer.
