About Allergic Conjunctivitis
Allergic conjunctivitis is a common allergic disease that affects 20% or more of the population worldwide.  The disease is characterized by inflammation of the conjunctiva (a membrane covering part of the front of the eye), resulting in ocular itching, excessive tear production, lid swelling, and redness. Antihistamines are commonly used to treat allergic conjunctivitis, but use is limited by lack of durable activity and ocular dryness.
