Allergies : Allergies cause itching & tearing. Over-the-counter allergy medicine & eyedrops help relieve it. Zaditor (ketotifen) is a good eyedrop. Blepharitis also causes itching & this can you can try loraditine (claritin) or other previous prescription anti-allergy meds. Check with your doctor if you have any medical conditions or are pregnant.
