Dealing With Dry Eyes

SATURDAY, Jan. 24 (HealthDayNews) -- Winter's dry air and wind can play

havoc with the almost 20 percent of Americans who have dry eyes.

Dr. Goins, an associate professor of ophthalmology and visual

sciences at the University of Iowa, explains the causes of dry eyes and ways

to manage the condition.

" Many different factors can affect the tear film quality and amount, which

leads to secondary changes in the eye and loss of vision, " Goins says.

The amount of lubricating tears produced by the eyes may vary, depending on

whether the eyes are at rest or under stress, such as when you're reading.

Pain, redness, decreased vision and the sensation of foreign objects in the

eyes are among the complaints cited by people with severe dry eyes.

Dry eyes can be caused by wind and sunlight; dirt and grit; an age-related

decrease in tear production; eyelid abnormalities that affect the blink

mechanism; and naturally and artificially dry environments, Goins says.

Medication side effects and diseases such as rheumatoid arthritis and lupus

can also cause dry eyes.

The approach you take to managing dry eyes depends on the cause, Goins says.

He recommends that people with dry eyes wear sunglasses to protect against

wind and excess light. Artificial tears (also known as tear substitutes) can

be used during the day and a lubricating ointment can be used at bedtime.

There's a difference between artificial tears that provide moisture and eye

drops that only remove redness from the eyes, Goins says.

Humidifiers can also help reduce dry indoor air during the winter.

People with significantly dry eyes or those who have pain or foreign object

sensations in their eyes should see an ophthalmologist, Goins says.
