What Causes Dry Eyes?

In addition to an imbalance in the tear-flow system of the eye, dry eyes can be caused by situations that dry out the tear film. This can be due to dry air from air conditioning, heat, or other environmental conditions. Other conditions that may cause dry eyes are:

  • The natural aging process, especially menopause.
  • Side effects of certain drugs such as antihistamines and birth control pills.
  • Diseases that affect the ability to make tears, such as Sjogren’s syndrome, rheumatoid arthritis, and collagen vascular diseases.
  • Structural problems with the eye lids that don’t allow them to close properly.
