Over ten million Americans suffer from dry eyes. This problem is usually caused by a problem with the quality of the tear film that lubricates the eyes.

One of the most common reasons for dryness is the normal aging process. As we grow older, our eyes produce less oil. This is more pronounced for women than for men. Without as much oil to seal the watery layer of the eye, the tear film evaporates much faster, leaving dry areas on the surface of the eye including the conjunctiva and cornea. Other factors such as hot, dry or windy climates, high altitudes, air conditioning and cigarette smoke also cause dry eyes. Contact lens wearers may suffer from dryness because the contacts absorb the tear film. Certain medications and diseases can also cause dry eyes.

Symptoms of dry eye syndrome include itching, burning, irritation, redness, blurred vision that improves with blinking, excessive tearing or increased discomfort after periods of reading, watching television or working on a computer.

Most people find relief from dry eyes by using artificial tears on a regular basis. Preservative-free tears are recommended because they are the most soothing and have fewer additives that could potentially irritate. Avoid products that whiten the eyes – they usually do not have adequate lubricating qualities.

In some severe cases, blocking the tear drain in the eyelid is indicated. This simple procedure can be done on a temporary or permanent basis. Some practical lifestyle changes can also improve dry eyes, such as humidifying the home or workspace.
