DRY EYE THERAPY AT EYES ON STONEHAVEN
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 poor function 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.
