                                                          Allergies can cause itching, redness, irritation, discharge, and swelling in eyes. This can be from direct contact, or subsequent to other response. Eye drops specifically made for allergies are available over the counter or by prescription. In Addition, try OTC oral allergy medications like Zyrtec.
