Dry Eyes

Dry eye syndrome is one of the most common complaints of adults over age 50. Tears, which help provide a uniform optical film over the front surface of the cornea, help lubricate the cornea.

As we age the tear film becomes unstable, due to glandular inadequacy, systemic medications, hormonal changes, and other age-related complications.

Dry eyes cause burning, stinging, and red eye symptoms. Ironically, one of the most common complaints of patients with dry eyes is excessive tearing, a result of the tear layer instability. Dry eyes affect 75% of the population over age 65.

There are certain factors that contribute to Dry Eye Syndrome, although both men and women of any age may experience it.

Aging: Advancing age is the single most important risk factor for Dry Eye. Dry Eye Syndrome affects 75% of the population over the age of sixty-five years.

Women: Hormonal changes brought on by pregnancy, lactation, oral contraceptives, menstruation, and post-menopause can cause Dry Eye conditions.

Disease: Several diseases result in side affects of Dry Eye Syndrome: Rheumatoid Arthritis, Diabetes, Thyroid Abnormalities, Asthma, Cataracts, Glaucoma, Lupus.

Medication: Certain medications can decrease the body’s ability to produce lubricating tears: Antidepressants, decongestants, antihistamines, blood pressure medication, oral contraceptives, diuretics, ulcer medication, tranquilizers, beta blockers.

Contact Lenses: Dry Eye is the leading cause of contact lens discomfort or intolerance. Soft contacts, in particular, rapidly evaporate the tears from the eye, causing irritation, protein deposits, infection, and pain.

Environmental Conditions: Exposure to smoke, fluorescent lights, air pollution, wind, heat, air conditioning, and dry climates can increase tear evaporation.

Computer Users: Computer users spend hours staring at their terminal ignoring their normal blinking process, which is a vital function of tear production.

Refractive Surgery: Candidates considering refractive surgery (i.e. RK, PRK, LASIK, LTK) should consult their Eye Care Professional regarding any dry eye risks associated with the procedure.
