For summer allergies, I recommend over-the-counter antihistamine eye drops containing Ketotifen or Olopatadine. These effectively target both itching and redness. Preservative-free lubricating drops (artificial tears) are also excellent for soothing irritation and flushing out pollen. Please avoid using 'redness-relief' drops (like tetrahydrozoline) for more than three consecutive days, as they can cause rebound redness and worsen your symptoms. If your symptoms persist, or if you experience eye pain or vision changes, please consult an eye care professional for a proper examination.
