090 WhatIsDryEyeWhat is Dry Eye?

Tears play an important role in keeping your eyes moist and comfortable throughout the day. They are made up of three different layers which are all vital in lubrication:

  • Lipid (oil) Layer: lubricates the eye and prevents tear evaporation
  • Aqueous (water) Layer: nourishes and protects the cornea
  • Mucin Layer: helps tears adhere to the eye

When your eyes do not produce or maintain enough tears to the keep the surface of the eyes lubricated, multiple symptoms can occur with the most common being dry and itchy eyes. This can be caused by reduced tear production or increased evaporation.

Most Dry Eye sufferers have issues relating to their Meibomian glands being blocked. These glands are along the lash line and create an oil layer for the tears to prevent them from evaporating as quickly.

What Causes Dry Eye?

Dry Eye typically occurs as a result of aging or hormonal changes. Other factors that can encourage Dry Eye include medications that reduce tear production, eye surgery, extended contact lens use, and environmental factors.
