Can you tell me the difference between the symptoms of pink eye and those of eye allergies?

Itchy: Can't always tell the difference based on symptoms, but sometimes pink eye starts in one eye first and then spreads to the other eye. Both are usually red and watery, but infections can cause more of a purulent discharge. Allergies usually have more of a itching component and can have other seasonal allergy symptoms outside of the eye.

Discharge matters: Allergic conjunctivitis causes severe itchiness and tearing with little discharge. Viral "pink eye" is characterized by mucous or thicker discharge, mattering of the eyelashes especially in the morning and a generalized sense of eye discomfort rather than a primarily itchy feeling.

Itch: Allergic conjuctivitis causes itchingb but pink eye typically does not.
