Eye Allergies

Eye allergies are similar to its nasal counterpart.This highly common eye condition occurs when an allergen irritates the eye, specifically the conjunctiva. The conjunctiva protects the sclera (white surface of the eyeball) and the inner folds of the eyelids from the external environment. In turn, the eyes would produce histamine to fight off the allergen. This would then result to the eyelids, conjunctiva and sclera redden and swell, while itching and tearing. It is not contagious and cannot be transmitted to people. Eye allergies are also called allergic conjunctivitis or ocular allergy.

Those who suffer from eye allergies tend to have accompanying nasal allergies. Symptoms of nasal allergies include sneezing and itchy and stuffy nose. The eyes are highly prone to allergies because it is directly exposed to the environment without a filtering system, unlike the nose. Eye allergies are usually harmless and temporary. They do not typically cause long-term consequences.

Conditions that are commonly mistaken for eye allergies include: bacterial or viral conjunctivitis, dry eye syndrome, and tear-duct obstruction. To learn more about eye allergies and other eye conditions, enroll in First Aid Training to be educated on proper treatment and management.
