Dry eye is a common condition that occurs when the eyes do not produce enough quality tears, leading to irritation, inflammation, and fluctuating vision that can affect daily comfort.
What Is Dry Eye?
Dry eye disease occurs when the tear film becomes unstable or insufficient, preventing the eyes from staying properly lubricated. Tears are made up of multiple layers—oil, water, and mucus—and each plays a role in maintaining a healthy ocular surface.
When this system is disrupted, the eyes can become irritated, inflamed, and more sensitive to environmental factors. Some patients produce too few tears, while others experience rapid tear evaporation due to poor oil gland function. Because dry eye can have multiple underlying causes, accurate diagnosis is essential for effective, long-term treatment.
