Frequent itchy eyes can be related to dry eyes as well as allergies, so it’s better to focus on artificial tear-based eye drops as well as anti-allergy eye drops. If the itching is mild, consider using sodium vitrate or polyvinyl alcohol eye drops to relieve dry eyes. These artificial tears eye drops can also flush allergens from the surface of the eye and relieve mild allergy symptoms. So if you have itchy eyes, you can prefer to use a certain amount of artificial tears eye drops to relieve the symptoms. If the use of artificial tears eye drops does not work, you can add anti-allergy eye drops, such as Olopatadine or Emastin eye drops, the combination of the above two drugs can usually relieve the symptoms of itchy eyes.
