I think my 2.5 year old has pink eye. some green discharge, not much redness at all. how do symptoms between viral and bacterial pink eye differ?

Conjunctivitis: Bacterial conjunctivitis is typically unilateral, one eye, but can be bilateral. There is usually a very significant colored discharge. Viral conjunctivitis is typically a clear, mucousy, discharge, and usually is, or becomes bilateral. And is contagious. Both should be evaluated by an ophthalmologist for proper treatment, which is not the same.
