Dry eye occurs when the eyes can’t maintain adequate moisture, either due to insufficient tear production or poor tear quality. Tears are vital for keeping your eyes lubricated, nourished, and free from infection.
The two main types are:
- Aqueous-Deficient Dry Eye: The tear glands don’t produce enough fluid.
- Evaporative Dry Eye:Tears evaporate quickly due to poor lipid layer quality or Meibomian gland dysfunction.
