Eye Allergies: What They Are and How To Treat Them

Eye allergies, scientifically known as allergic conjunctivitis, extend beyond the common sneezing and sniffling associated with allergies. For many, red, swollen, and itchy eyes become a significant manifestation, whether accompanied by uncontrollable sneezing or not.

These allergic reactions stem from a misdirected response of the immune system triggered by allergens. Allergens, such as pet dander, pollen, and dust, cause the immune system to react negatively to harmless substances. The resulting allergic response releases histamine, a chemical that leads to dry eyes and increased tear production, aiming to flush out perceived foreign objects. Inflammation of the blood vessels contributes to the bloodshot appearance of the eyes.

Symptoms of allergic reactions can manifest diversely. Redness, irritation, or itching of the eyes, sensitivity to light, and swollen eyelids are common indications. In more severe cases, individuals may experience a painful or burning sensation, excessive tearing, a runny nose, sneezing, or a stuffy nose.

Allergens causing these reactions range from grass, weed, and tree pollen to dust and pet dander. Surprisingly, everyday items like makeup, perfume, and contact lenses can also be allergens. Notably, allergic symptoms may appear immediately or up to four days after initial contact with an allergen.
