3 Layers of the Tear Film

The tear film is a gradient, which is comprised of three main layers.


1. Oil Layer

The outermost layer is comprised of oil, which serves to seal the tear film

and prevent the evaporation of our tears. Oils are released by our

meibomian glands and blocking of these glands can result in an evaporative

type of dry eye.

2. Water Layer

The middle layer is the water or aqueous layer, which has the main role of lubricating the eye. The water layer is produced by our lacrimal gland which is innervated by corneal nerves and influenced by hormones. 

3. Mucin Layer

Lastly, the innermost mucin layer helps the water and oil layer adhere evenly over the eye. It sits directly on top of our corneal cells and nourishes them. Without a proper mucin layer, tears would be constantly running down our cheeks.

Meibomian Gland Dysfunction and Forma-I Therapy

Meibomian glad dysfunction (MGD) refers to blockage and poor function of the meibomian glands. Approximately 85% of dry eye is associated with some level of MGD. At Eyes On Stonehaven, we use the revolutionary InMode Forma radio frequency treatment to help unblock clogged meibomian glands and restore the oily layer of the tear film.
