Eye Allergy
1/14
Eye allergies occur when allergens irritate the conjunctiva or the delicate membrane covering the eye and the eyelid. The body recognizes these allergens as foreign objects and triggers an immune response by releasing immunoglobulin E (IgE) molecules. This results in reactions, such as itchiness, watering eyes, soreness, swelling, among other symptoms. Eye allergies occur along with allergic rhinitis or asthma and do not cause a threat to vision.
