Dry Eye Syndrome

-back to Patient Education-

Tears are vital to maintain the health of the eye and to maintain good vision. Tears wash and lubricate the cornea and the tissues that form the surface of our eyes and lids, and they also provide oxygen and nutrients to tissues that are not supplied with blood vessels.

If your eyes do not have the right amount of tears, or if the composition of the tears is incorrect you may experience a variety of uncomfortable symptoms that are generally classified as “Dry Eye Syndrome.” Symptoms may include a gritty feeling, pain, redness, blurred sight or the feeling of having something in your eye.

In certain conditions we may all experience transient dryness; being in dry environments, like air conditioned or a smoke-filled room, staring at computer monitors or TV screens, being outdoors on windy or cold, dry days, etc. Contact lens wearers are especially aware of dry eye conditions because the lens itself may influence tear production and tear retention. And, allergy sufferers often experience changes in tear production. Normally our eyes will make natural corrections in tear production as a reaction to temporary changes in conditions.

Interestingly, Dry Eye Syndrome may result from too much tearing as well. If tears are too “watery” the fluid runs off the eyes and evaporates without lubricating or cleansing the cornea, which will soon cause discomfort, burning, itching, and blinking. Not enough fluid will result in tears that are thick with mucus and oils that do not properly coat the outer surfaces of the eyes. Again, the “dry eye” symptoms will cause increasing discomfort.

Over-the-counter eye drops (artificial tears or wetting agents) will offer some temporary relief and are recommended for occasional use. But if the problem persists a visit to the eye doctor is advised. It is important to check for allergic or environmental causes, infections or conditions that may affect the eyelids (where tears are produced). The doctor will be able to determine if there is a need to treat for poor tear production or for poor tear drainage.
