Allergic Conjunctivitis – Identifying Allergens
Pollens (weed, grass, and tree), dust mites, mold spores, animal dander and feathers, and perfumes are among the common allergens causing allergic conjunctivitis. In recent years, topical medications, contact lenses, and contact-lens solutions also have been known contributors to allergic conjunctivitis.
Factors that affect the intensity, frequency, and duration of allergic conjunctivitis include humidity, temperature, and a person’s activity. In general, cooler temperatures seem to alleviate the symptoms of allergic conjunctivitis, whereas hot and dry weather usually intensify and aggravate the condition.
People who complain of severe itching and inflammation should be checked by a doctor for atopic keratoconjunctivitis (a perennial and severe ocular inflammatory condition associated with atopic dermatitis, or eczema, in adults) or vernal conjunctivitis (severe ocular itching that occurs in the spring and usually affects children between the ages of 11 and 13).
