Allergic disease is more common in spring or summer.
What are the symptoms of conjunctivitis?
Conjunctivitis can be unilateral, or most likely bilateral, as viral infections are extremely contagious. The main symptoms are red eyes, with discharge and watering. You may also have gritty eyes, discomfort, itching, and blurred vision. In some cases, the inflammation causes the eyelids to be swollen and red.
