Common causes of Dry Eye Syndrome include:
Hormonal changes such as menopause, hypothyroidism
Autoimmune diseases such as rheumatoid arthritis, Lupus, Rosacea, Sjogrens Syndrome
Medications (both prescriptions and non-prescriptions) especially diuretics, vasoconstricting drops such as Visine,
and Murine, antihistamines -both drops and pills, allergy medications, etc.—check the labels
Environmental factors such as prolonged computer usage, long hours of reading, smoke, and dust environments, air conditioning drafts and ceiling fans—especially while sleeping at night, dry environments such as airlines, kitchen cooking ovens
Contact lens—especially if cleaning solutions are used daily or contacts are continuously worn. Using daily wear contacts are less likely to induce reaction. Using preservative free artificial tears and hydrogen peroxide cleaners frequently helps.
Poor or inadequate facial/lid/ocular hygiene, using “non-antibacterial soaps” such as Dove, Ivory, Neutrogena or “water only” on the face causing the meibomian glands that make the oil to be chronically infected, inflamed, and blocked.
Anatomical changes around the eye as a result of eye lid surgery, droopy or mal-positioned lids, inability to close eye or blink properly (either anatomical or neurologic etiology)
