Dry eye is a common condition that occurs when the eyes do not produce enough tears or when the tear film is unstable, leading to irritation, discomfort, and fluctuating vision.
What Are Dry Eyes?
Dry eye disease occurs when the tear film—the protective layer that keeps the eyes lubricated—becomes imbalanced. This can happen due to reduced tear production, poor tear quality, or excessive tear evaporation. Tears are made up of multiple components, including water, oil, and mucus.
If any part of this system is disrupted, the surface of the eye can become irritated and inflamed. Because dry eye can have multiple underlying causes, effective dry eye treatment begins with a precise diagnosis.
