What should you know about red and itchy eyes treatment?

Itching with redness commonly fits an allergic reaction affecting the eye surface, especially when both eyes water or symptoms appear around dust, pollen, or animals. Allergic conjunctivitis can occur alongside a blocked or runny nose; see the page on Allergic Rhinitis for that pattern. Dryness, smoke, cosmetics, contact lenses, and rubbing can also inflame the surface. A symptom does not identify its cause on its own.

Do not rub your eyes, and wash your hands before touching them. A cool, clean compress can calm itching. Reduce exposure to smoke, dust, fragranced products, and a suspected allergen; keep windows closed during heavy outdoor pollen and wash your face after being outside. If you wear contact lenses, remove them until your eyes feel well and seek advice before restarting. A pharmacist or clinician can help select Allergy Medication, such as an appropriate antihistamine or eye drop, based on your symptoms and other medicines.

Arrange prompt medical assessment for eye pain, light sensitivity, marked swelling, a change in vision, injury, chemical exposure, or thick discharge. Seek emergency help if vision suddenly worsens, severe pain develops, or swelling affects breathing. Contact-lens wearers should seek same-day advice for a painful red eye because infection can threaten the cornea.

Could this be allergic conjunctivitis, dryness, infection, or irritation? Which drops are suitable with my contact lenses or other medicines? How long should I try self-care before arranging a review?
