What Is Dry Eye Syndrome?
Dry Eye Syndrome (DES) is a common ocular condition caused by insufficient tear quantity or poor tear quality, leading to discomfort and vision issues. Según la Academia Americana de Oftalmología (AAO), it affects nearly 16 million adults in the U.S. and is more prevalent with age. While many experience occasional dryness, chronic dry eye can severely affect quality of life and requires proper management.
Main Causes of Dry Eye
-
Aqueous Deficiency: Tear glands produce fewer tears, often due to aging, autoimmune diseases like Sjögren’s syndrome, or medication side effects (National Eye Institute, NEI, 2023).
-
Excessive Evaporation: A faulty lipid layer causes tears to evaporate too quickly, worsened by environmental factors like dry air or prolonged screen use (NEI, 2023).
