Can wearing contact lenses cause allergies?


      Every season change is often the peak season for allergies. Recently, many friends may find that after wearing contact lenses, their eyes are red like a little rabbit, and they suddenly have itching from time to time. In this case, you should pay attention, because it may be the symptoms of eye allergy!
      Why do contact lenses cause allergies? The relationship between the eyes and contact lenses is delicate. While they can coexist harmoniously when properly fitted, improper prescription often leads to various issues. Contact lenses themselves pose risks: Poor material permeability causes corneal hypoxia, triggering excessive secretion of metabolic byproducts. These proteins and oils tend to adhere to the lenses, potentially causing allergic reactions upon contact. Beyond lens factors, lens care solutions are also common allergens. Some individuals develop hypersensitivity to specific solutions, experiencing redness, swelling, or increased discharge immediately after use. However, switching to a different solution typically resolves these symptoms, indicating an allergic reaction to particular components in the solution.
Fundamentally, allergic reactions primarily stem from the body's immune rejection mechanisms, which are closely tied to individual constitution. If not triggered by contact lenses or solutions, exposure to other allergens could be responsible. Seasonal allergies like spring pollen, summer willow catkins, and autumn dust represent contact-type reactions, while dietary factors introduce even more potential triggers. Common allergenic foods include nuts, peanuts, fish, shellfish, eggs, dairy products, wheat, and soybeans. Additionally, pre-existing ocular conditions such as keratitis or conjunctivitis may exacerbate allergic reactions when irritated.
    When allergic reactions occur, stop wearing contact lenses immediately to avoid additional irritation and prevent bacterial infections. Refrain from rubbing your eyes with hands, keep the area clean and dry, and use anti-allergy medications or anti-inflammatory eye drops under a doctor's guidance for treatment.
For individuals with allergic constitutions who need contact lenses, prevention is crucial by avoiding known allergens. Change lenses frequently, preferably short-wear types, and ensure timely replacement of lens care solutions and storage cases. Maintain daily disinfection practices. During peak allergy seasons or when physical immunity is low, it's essential to avoid wearing contact lenses altogether!
