What is Dry Eye?

Dry eye affects millions of adults in the United States and is more common in women than in men. When the surface of the eye is not adequately lubricated due to a low quantity or quality of tears, dryness occurs.

If tear production decreases, tear evaporation increases, or the composition of tears is imbalanced, dry eye can occur.

The Importance of Tears

Tears are essential to the overall health of our eyes. Our tears have many important functions. Each time we blink, our tears provide protection for our eyes. They also lubricate, remove particles, and keep our eyes smooth. The lubrication helps prevent dry eye.

Tears are made up of three layers; oil (lipid), water (aqueous) and mucin layer (a mixture of oils, water, mucus, proteins) which work to keep the surface of the eye smooth and protected.

Tears continuously lubricate the surface of the cornea in healthy eyes nourishing its cells and adding a layer of protection from harmful environmental factors; such as irritants and allergens. When tears decrease or their composition changes, the health of they eye and vision may become compromised.

Dry Eye Symptoms:

  • Stinging or burning
