Eye Allergies
When life had begun to appear on earth, one of the first things to develop was the eyes. The importance of eyes for the survival of any species on the earth can be gauged from this fact. The defense mechanisms put up by the body to protect eyes are quite striking. It includes the eyelids, eyelashes and the conjunctiva, which covers the eyeball. In spite of all this defense mechanism of the body, eyes continue to be one of the most sensitive organs in the human body and are always open to the attack of airborne allergens.
Tears continuously keep the eyes clean but are ineffective when dealing with allergens. An allergy occurs due to the immune response of the body to a foreign particle. Most of the time an allergy is caused by the overreaction of the body. In the eyes, the allergic reaction occurs to the conjunctiva – a transparent membrane covering the eyeball and the under surface of the eyelid. Dust, mold, pet dander and tree pollen are some of the most common allergens. If you are allergic to a particular substance, and when your eyes come into contact with the substance, it will kick start an allergic reaction.
It is estimated that more 50 million Americans suffer from various type of allergies. In it, majority of the people suffer from eye allergies. People with allergic rhinitis or atopic dermatitis or strong family history of allergy are more prone to have eye allergies.
Eye allergies rarely cause vision impairment. Itching is the most vital symptom of allergic eyes. Although most of the eye allergies are not dangerous, persistent eye allergies should be treated and it is wise to administer drugs after consulting and ophthalmologist.
