Keratoconjunctivitis Sicca also known as Dry Eye Syndrome is when your body is not able to produce enough tears to properly lubricate the eye
The transparent layer forming the front of the eye known as the cornea is kept continually wet by basal tears. Occasional or chronic insufficient lubrication on the surface of the eye can result in discomfort. Sometimes the condition results in watery eyes from “reflex tearing”. This occurs when your body responds to the lack of moisture by creating excessive tears, your body’s attempt to re-lubricate as well as wash out irritants.
