This happens when tear glands cannot make enough tears or produce poor quality tears. Dry eyes can be uncomfortable, causing itching, burning, or rarely some loss of vision. Your eye doctor may suggest using a humidifier in your home, special eye drops that simulate real tears, or plugs that are placed in tear ducts to decrease tear drainage.
Dry eye syndrome has many causes. It occurs as a part of the natural aging process (especially during menopause in women); as a side effect of many medications, such as antihistamines, antidepressants, certain blood pressure medicines, Parkinson’s medications and birth control pills; or because you live in a dry, dusty or windy climate.
If your home or office has air conditioning or a dry heating system, that too can dry out your yes. Another cause is insufficient blinking, such as when you’re staring at a computer screen all day.
Dry eyes also are a symptom of systemic diseases such as lupus, rheumatoid arthritis, ocular rosacea or Sjogren’s syndrome (a triad of dry eyes, dry mouth and rheumatoid arthritis or lupus).
Long-term contact lens wear is another cause; in fact, dry eyes are the most common complaint among contact lens wearers. Recent research indicates that contact lens wear and dry eyes can be a vicious cycle. Dry eye syndrome makes contact lenses feel uncomfortable, and evaporation of moisture from contact lenses worsens dry eye symptoms. Newer contact lens materials and lens care products can help reduce contact lens dryness.
