Dry eye means that your eyes do not produce enough tears or that you produce tears which do not have the proper chemical composition.  This is a problem because the tears your eyes produce are necessary for overall eye health and clear vision. Symptoms of dry eye may include irritated, scratchy, dry, uncomfortable or red eyes, a burning sensation or feeling of something foreign in the eyes and blurred vision. Excessive dry eyes may damage eye tissue, scar the cornea (the front covering of your eyes) and impair vision and make contact lens wear difficult.

 

Often, dry eye is part of the natural aging process, but it can also be caused by blinking or eyelid problems, medications like antihistamines, oral contraceptives and antidepressants, a dry climate, wind and dust, general health problems like arthritis or Sjogren's syndrome and chemical or thermal burns to your eyes.

 

If you have symptoms of dry eye, see your optometrist for a comprehensive examination. Dry eye cannot be cured, but your optometrist can prescribe treatment so your eyes remain healthy and your vision is unaffected. Some treatments include blinking more frequently, increasing humidity at home or work, and using artificial tears and a moisturizing ointment, especially at bedtime. In some cases, small plugs are inserted in the corner of the eyes to slow tear drainage. Sometimes, surgical closure of the drainage ducts may be recommended.
