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.

Pink eye or allergies, how can I tell the difference?

Sometimes difficult: This is sometimes difficult even for experts. Generally allergies have more itching than pink eye and occur in people have allergic symptoms such as coughing, sneezing and so forth. You can try over-the-counter antihistamine drops such as zaditor (ketotifen). If this does not help, see an ophthalmologist.

Both eyes vs 1 eye: Not a hard fast rule but usually allergies affect both eyes at the same time and is intensely itchy. Viral or bacterial conjunctivitis usually affects one eye first and not that itchy. An infected eye also may produce mucous or pus like secretions.
