What is Dry Eye Syndrome?

Dry Eye Syndrome (D.E.S.) is the most common eye disorder occurring in approximately 20% of the population. It is the result of a decline in the quantity or quality of tears produced. This happens when the tear glands in the upper and lower eyelids do not produce enough of the right kind of tears.

The Complexity of Tears

Tears function to protect your eyes and keep them lubricated and comfortable. Your eyes produce two types of tears:

Lubricating tears that moisturize and protect your eyes from infections

Reflex tears that respond to environmental stimuli (dust, smoke, etc.), injury or emotion

Interestingly enough, ‘watery’ eyes can be a symptom of D.E.S. Irritants that cause D.E.S. can trigger the production of reflex tears. However, since reflex tears do not have the proper lubricating components, the discomfort remains.
