Full Answer

Allergic conjunctivitis is known as one of the most treatable and common eye conditions in both adults and children, reports WebMD. Also known as pink eye, allergic conjunctivitis is not a contagious condition. Some common symptoms include an increased amount of tears, blurred vision, redness of the conjunctiva, swelling of the eyelids and itchy eyes. Most cases of pink eye disappears as soon as the allergen is removed or when the affected person takes ocular antihistamines, steroids, decongestants or mast cell stabilizers.

There are two types of allergic conjunctivitis: acute allergic conjunctivitis and chronic allergic conjunctivitis, according to Healthline. Acute allergic conjunctivitis is a short-term eye condition that usually flares up during the local allergy season. A watery nose and swelling, itching and burning eyelids are usually associated with acute allergic conjunctivitis. Chronic allergic conjunctivitis is less common, but it can strike any time of the year. While it has similar symptoms to acute allergic conjunctivitis, light sensitivity is more common with this condition.
