Allergic conjunctivitis caused by eye allergies is very common. Eye allergies, like other types, can be triggered by allergens including pollen, animal dander and dust mites.
The most common symptom of allergic conjunctivitis is itchy eyes, which may be relieved with special eye drops containing antihistamines to control allergic reactions. These eye drops are available both over the counter and by prescription.
Avoiding the allergen is also important in the treatment of allergic conjunctivitis. Allergic conjunctivitis can be seasonal or perennial (year-round), depending on the allergen causing the reaction.
