Dry Eye is one of the most under-diagnosed eye diseases, and yet it is the most common reason why patients go see their eye care professional.
Dry Eye occurs when eyes do not produce the enough tears or the tears are of a poor quality. Women are more frequently affected than men, and it is often caused by hormonal changes due to aging or medical conditions.
Many people mistake the Dry Eye symptoms for allergies, climatic conditions or just "eyestrain." While all of these may aggravate Dry Eye symptoms, they are not the cause.
Your eyes need a constant layer of tears to maintain and protect your eyes' surface. In Dry Eye, underlying changes to the health of the tear-producing glands can result in a change in the quantity and quality of the tears you make. This results in a tear film that can no longer provide enough nourishment or protection to the surface of your eye. This can lead to damage of your eye's surface, which, in turn, can lead to the symptoms of Dry Eye.
