Our tears are made up of three layers: the lipid (oil) layer, aqueous (water) layer, and the mucous (sticky) layer. These layers work in unison to lubricate and coat the eyes, keeping them moist and comfortable.

Your meibomian glands control the lipids in the eye, called meibum, which combine with other substances in the eye area to create a thin film that consistently lubricates your eyes. Meibum is an essential part of your eye’s makeup as it prevents the evaporation of the eye’s tear film.

Meibomian Gland Dysfunction occurs when the meibomian glands fail to provide enough meibum. This can be triggered by various factors and causes the tear film to evaporate at a quicker rate, leading the eyes to feel dry and uncomfortable. 80% of Dry Eye is due to MGD.
