What is Dry Eye Syndrome?

The tear film is a complex mixture of water and chemicals that moisturize and protect the eye. It also acts as a focusing surface for the eye. Dry eyes are caused by an abnormality of the tear film.  Dry eyes does not necessarily mean your eyes will feel “dry”. Itching, burning, scratchy sensation, or intermittent blurring of the vision can all be symptoms of “Dry Eye”.
