Dry eye syndrome (keratoconjunctivitis sicca) occurs when the tear
glands do not make enough tears or when too many tears evaporate from the surface of your eye. This causes your eyes to feel itchy, scratchy,
and irritated. It is more common in older adults and in those with autoimmune
diseases, such as arthritis.
Wearing contact lenses may increase
your risk for dry eye syndrome. Dry eyes also may be caused by certain
medicines, such as antidepressants, antihistamines, and diuretics.
To help soothe your dry eyes, you can try an over-the-counter lubricant eye drop (artificial tears solution), such as Hypo Tears or Systane. Do not use eyedrops that reduce redness (such as
Opcon-A) to treat dry eyes. You can also try to blink a lot, limit your time in air-conditioned or heated rooms, and use a humidifier in rooms where you spend a lot of time.
If you've used artificial tears for a few days and they don't seem to be helping, call your doctor.
Excessive dryness can damage your eyes. And your doctor may recommend other treatments, including:
Prescription eyedrops, such as cyclosporine (Restasis).
Punctal occlusion, in which the eye doctor inserts a plug to block your
tear drainage system. It helps preserve the natural
tears on the surface of your eye.
