Constant itchy and red eyes are typically caused by eye allergies or dryness. For quick relief, you can use over-the-counter antihistamine eye drops (like Ketotifen or Olopatadine) if it is an allergy, or preservative-free lubricating eye drops (artificial tears) for dryness and irritation. Applying a cool compress to your closed eyes can also help soothe the itching. Please avoid rubbing your eyes, as this worsens inflammation. If your symptoms persist, or if you experience pain, discharge, or changes in your vision, please consult an eye doctor for a proper evaluation and targeted prescription treatment.

Allergic conjunctivitis usually begins to improve within 24 to 72 hours once you start treatment and avoid the allergen, though it can last as long as you are exposed to the trigger. For quick relief, I recommend over-the-counter antihistamine eye drops containing ketotifen or olopatadine. Lubricating artificial tears are also excellent for flushing out allergens and soothing irritation. If you have nasal symptoms, oral antihistamines like cetirizine can help. Please avoid rubbing your eyes, as this worsens inflammation. If symptoms persist beyond a few days or you experience vision changes, please consult an eye specialist for prescription-strength drops.
