Dry Eyes
Older adults are more prone to developing chronic dry eyes. The cause of the eye dryness is the lack of lubrication due to an inadequate amount of tears. Clear vision is dependent upon adequate lubrication, and tears keep the front surface of the eyes healthy.
Tears are not only lubrication. As they spread across the front of the eyes when blinking, they wash away foreign bodies, prevent infections, and keep the eye surface clear. Tears are produced by glands around the eyelids, and the excess tears drain away into the sinuses through small drainage ducts in the corners of the eyes. Unbalanced tear production and drainage lead to dry eyes.
Many factors can affect tear production – age, medications, wind, or dry climates. Dry eyes can also be caused by prolonged computer use, air-conditioning, bike riding, and airplane rides.
Over-the-counter eye drops (artificial tears) can treat occasional or mild dry eyes, but more severe cases may need medical treatment. The type of treatment cannot be made until the cause of the dry eyes is determined. Some lifestyle modifications may help alleviate some of the dryness.
If you are suffering from dry eyes, call Parkview Optometry to schedule an assessment.
