What Is Dry Eye Disease?

Dry eye disease causes discomfort, pain and damage to the surface of the eye by disrupting the moisture layer on the surface of the eye.

This can have a significant impact on your quality of life and your vision.


The Tear Film

The tear film is the very thin layer of moisture approximately  100 um thick that covers and protects the entire surface of the eye.  It is a complex layer made of:

  • Oil (meibum) from the meibomian glands of the eyelid
  • Water (aqueous) from the lacrimal gland
  • Gel (mucus) from the surface of the eye itself (cornea and conjunctiva).


Any disruption to these layers is a form of dry eye.  The most common form of dry eye disease is blepharitis - clogged up oil glands in the eyelids.


What Are The Symptoms Of Dry Eye Disease?


Any irritation can be a form of dry eye, everyone's experience of dry eye is different, and can fluctuate through the day depending on how much heat, wind and airborne particles you’re exposed to.
