Problems with Tear Ducts
-
Infections in your lacrimal gland, and damages done to it are dry eye causes as well.
Air Conditions
-
Air in airplanes, air conditioners and heating systems cause dry eye. It can also be caused by dry weather such as in a desert or even on a windy day (even though wind usually causes tearing). Whenever there isn't moisture in the air, eyes can become dry.
Contact Lens Use

Contact lenses can absorb tears and cause eyes to feel irritated and dry. Contacts with polymers, a low water content, or RGP (Rigid Gas Permeable) lenses are best to prevent this since they are formulated to prevent dry eye discomfort for the wearer.
Other Common Causes
-
Old age, diabetes, menopause, recent surgery to the eye, Vitamin A deficiency and arthritis can also be causes. Straining your eyes by reading, using the computer or watching television excessively can cause dry eyes.
