All About Dry Eye

Science

Dry eye is one of the most
under-diagnosed ocular diseases,

and yet the symptoms of Dry Eye are the most common complaints of patients when they see their eye care professional.

Women are more frequently affected than men. Dry Eye Disease is often caused by hormonal changes due to aging, menopause, and other medical conditions or their treatments.

Your eyes need a constant layer of healthy, balanced tears called the “tear film” to stay nourished and protected. A change in the quality or the quantity of your tears can result in an un-balanced tear film. The best known indicator for this imbalance is tear film osmolarity. When the osmolarity of your tear film is high, it is a clear indicator of Dry Eye Disease. The osmolarity of your tear film can only be measured by your eye doctor. It is important to know the health of your tear film, as heightened osmolarity may put you at risk for damage to the surface of your eyes.
