What is Dry Eye?

Dry eye is a condition in which the eye produces fewer or lower quality tears and is unable to keep its surface lubricated. The main symptom of dry eye is usually a scratchy feeling or as if something is in your eye. Other symptoms include stinging or burning in the eye, episodes of excess tearing that follow periods of dryness, discharge from the eye, and pain and redness in the eye. Sometimes people with dry eye also feel as if their eyelids are very heavy or their vision is blurred.
