Viral pink eye usually affects both eyes. Children usually have viral symptoms such as runny nose, congestion or cough when they develop viral pink eye. Bacterial pink eye usually affects one of the eyes, and causes excessive discharge. Allergic pinkeye occurs when allergens irritate the conjunctiva.
