    How to diagnose Dry Eye ?
    ### Response:
    Diagnosis of dry eye requires a comprehensive eye evaluation. Your eye care professional will ask you about your symptoms, your overall health (conditions for which you are treated, medications that you take), your eye history (use of contact lenses, past refractive or other eye surgery), and aspects of your daily environment (exposure to environmental allergens or occupational hazards).
