Dry Eye

In order to maintain eye health, your eyes must continually produce and drain tears. Tears keep the eyes lubricated, help heal wounds and protect against eye infection.

Having dry eye means your eyes will produce insufficient or poor quality tears, making it difficult or impossible to keep the eye surface lubricated and comfortable.

Tear Film Layers

Tear film is comprised of three layers, each with its own function.

  • Lipid: Outer, oily layer that keeps tears from evaporating too quickly
  • Aqueous: Middle layer that nourishes the cornea and conjunctiva
  • Mucin: Bottom layer that helps to keep the tears spread evenly over the eye
