Dry eyes can happen when your tears do not adequately lubricate your eyes. Tears bathe the surface of your eyes to keep them moist and to rinse away dust, debris, and microorganisms that can harm your eye. Dry Eye Syndrome can make your eyes burn or sting and leave your eyes feeling gritty, scratchy, and irritated.
There are five leading causes of dry eyes.

Dry eyes can occur when your eyes do not produce enough tears, a condition known as keratoconjunctivitis sicca. This condition may be the result of aging, inflammation, or damage to the glands that produce tears.
