Dry eye syndrome is a chronic deficiency of tears, or moisture in the eye. Some causes are obvious—dry climates or the use of certain drugs. Others are less obvious, like staring at a computer all day and not blinking. Dry eyes are more common in women, especially after menopause. And some people with dry eyes may have tears that run down their cheeks, due to an inability to keep tears in the eye.

Symptoms range from constant irritation to inflammation of the anterior (front) tissues of the eye. Either the eye doesn't produce enough tears, or the tears evaporate too quickly. Dry eyes can have several causes: natural aging, especially menopause; long-term contact lens wear; a dry, dusty or windy environment, and side effects from the use of antihistamines, antidepressants, certain blood pressure medicines, Parkinson's medications, and birth control pills.

Air conditioning or a dry heating system can dry out eyes, as well as insufficient blinking. In more serious aspects, dry eyes can indicate systemic diseases. Dry eye syndrome may not be cured, but often the scratchiness and burning can be managed.

Treatments may include topical lubrication with drops, gels and ointments. It may help to plug up the duct that drains the tears from your eye with soft semi-permanent silicone plugs.

Oral Omega 3 oils may help as well. There is also a prescription drop that when used over several months may actually increase your tear production. It’s called Restasis.
