Understanding Tear Film & Dry Eye

The tear film is made up of three unique layers:

  1. Oily layer: Small glands at the perimeter of the eyelid, called meibomian glands, produce the outer, oily layer of the tear film. The main purpose of this oily layer is to smooth the tear surface and decrease evaporation of tears.
  2. Watery layer: This is the largest of the three layers and it makes up most of what we ordinarily think of as tears. This watery layer is produced by small glands scattered through the conjunctiva, the delicate membrane lining the inside of eyelid and covering the eyeball, and by the major tear gland, the large lacrimal gland.
  3. Mucin layer: The innermost layer consists of mucus produced by goblet cells in the conjunctiva. This layer allows the watery layer to spread evenly over the surface of the eye and helps the eye to remain quite moist. Without mucus, tears would not stick to the eye.
