For eye irritation caused by the sun and dust, you can use preservative-free artificial tears to wash away particles and soothe dryness. For itching and allergies, over-the-counter antihistamine eye drops containing ketotifen or olopatadine are very effective. If redness is prominent, drops with naphazoline can help, but use them for no more than three consecutive days to avoid worsening redness. Wearing UV-blocking sunglasses and avoiding rubbing your eyes will also speed up recovery. If your symptoms worsen or if you experience pain or vision changes, please consult an eye specialist for a personalised evaluation.
