Tears are necessary for eye health. Dry Eye occurs when eyes do not produce sufficient tears or the tears evaporate too quickly. Without proper treatment, inadequate tears can make it frustrating to read, watch TV, drive, work on the computer, and many other personal or professional activities.
The most common form of Dry Eye is Evaporative Dry Eye, which affects 86% of Dry Eye cases. This form results from a shortage of oil in your tears caused by a blockage in your eyelid (Meibomian) glands, leading tears to evaporate faster than normal.
