What allergies cause face and eyes to itch and swell up?

Airborne allergies: When airborne allergens such as animal dander, pollen, mold or even dust mite contact the moist surfaces of the eyes, it can lead to tearing, red, puffy and itchy eyes. If the person is significantly sensitive it can lead to mild facial swelling. An allergist can assist in determining the trigger in an effort to avoid future contact and provide recommendations on treatment such as antihistamines.
