Some people with dry eyes actually have excessive tear production. Many older people are bothered by dry eyes because the liquid that bathes the eye with each blink is deficient in protective mucus, or because tear production is reduced. Women have this problem more often than men. Dry eyes can be a symptom of various diseases, such as rheumatoid arthritis, systemic lupus erythematosus, or Sjogren s syndrome. Without treatment, dry eyes can develop increasing sensitivity to bright light.
Associated damage can lead to visual loss.
Dry eyes can be relieved with eyedrops known as artificial tears , which mimic the protective action of natural tears. Many such products are available without a prescription. Be careful to use them as directed. These drops should be used every few hours generally, at least four times a day, but your physician will tell you what is best for you. They are especially helpful for reading or other activities that require a lot of eye movement.
