Dry Eye Facts


The Tear Film

The tear film covers and protects the front of your eye or corneal surface. It has 3 layers, the mucin layer, the aqueous layer and the lipid layer (see below).

Dry Eye Disease

Dry Eye (also known a Dry Eye Syndrome or Dry Eye Disease) is a common condition affecting people of all ages. It occurs when there is an insufficient volume and/or quality of tears to keep the surface of the eye sufficiently lubricated. This can result in eye discomfort.

Dry eye can be accompanied by and often is caused by Blepharitis and Meibomian Gland Dysfunction (MGD).


Blepharitis

Blepharitis is a common inflammatory condition where the edges of the eyelids become red, swollen and inflamed. Blepharitis is often caused by a build-up of bacteria living along the eyelid and eyelashes.


MGD

Meibomian Gland Dysfunction (MGD), is a chronic condition which occurs when the glands in the eyelids don’t produce enough oil, or the oil that is produced is of poor quality. This oil is called Meibum. It protects the watery layer of tears which cover your eyes and prevents them from drying out.
