Dry eye is a common condition in which the eyes are insufficiently lubricated, leading to itching, redness and pain. The eyes can become dry and irritated because the tear ducts are not producing enough tears, or because there is a chemical imbalance in the tears themselves. Natural tears require a chemical balance to lubricate the eyes efficiently. In addition, Blepharitis and Meibomian Gland Disease are a major cause of dry eyes.
Alleviating the symptoms of dry eye is important. Left untreated, they have the potential to damage vision. Dry eye can be diagnosed after a thorough examination of the eyes, and a test to evaluate tear production.
