Allergic reactions make eyes itching, irritated and watering.
The best treatment of allergic reactions would be to avoid the allergen but often it is not known. There are many different medications, pills, eye drops, and nasal sprays to reduce the symptoms.

Since the reaction is superficial, medications that do not get deeper into the eye should be used.
