A healthy tear film, spread across the eye by a blink, makes the surface of the eye smooth and clear. Without an adequate tear film, sharp vision is not possible.

Dry eye occurs when the eye does not produce enough tears, or an adequate quality of tears, to keep the eye healthy and comfortable.

Symptoms of Dry Eye

• Stinging or burning
• Scratchiness
• Stringy mucus in or around the eyes
• Excessive irritation from smoke or wind
• Excess tearing
• Momentary or persistent blurring of vision

Causes of Dry Eye

Age often decreases tear production, causing dry eyes, particularly in post-menopausal women. Sjögren's syndrome, some eyelid disorders, environmental factors and certain medications may also cause dry eye.

Treatment

Artificial tears often provide relief by lubricating the eyes and helping replace the natural moisture layer. These are available without a prescription and can be used as often as necessary.

Punctal plugs are inserted into the channel where tears drain out of the eye and into the nose, conserving natural tears and making artificial tears last longer. These are inserted in the office by an ophthalmologist.

Restasis, a prescription drug, may help increase the eyes' natural ability to produce tears.
