The Three Layers That Make Up the Tear Film

  • The First Layer is the Mucous Layer

    The inner tear film layer contains mucin or mucous-like substance. This layer is produced by goblet cells which are located on the surface of the eye. This mucin or mucous-like material provides the base of the tear film on the eye, providing a hydrophilic layer, and it promotes the smooth and even distribution of the tear film.

  • The Second Layer is the Aqueous Layer

    The tear film layer that rests on top of the mucous layer contains water, enzymes, chemicals, minerals, and proteins. The water layer is produced by the lacrimal gland. Most people have the false impression that this is the only component of their tears or that their tear film is just water.

  • The Third Layer is the Liquid Layer

    The outer layer contains oil or lipids produced by the Meibomian glands which are located in the eyelids. There are approximately 24 to 25 glands in each eyelid that produce the lipids. The Meibomian glands secrete their oil from small openings on the edge of the eyelid onto the tear film. The oily layer floats on top of the liquid layer and provides a barrier to keep the middle liquid layer from evaporating from the eye. This oil also helps with lubrication.

    Good Afternoon:
    Thought I’d give you a heads-up for a true community service feature.

    James Croley, MD is an eye surgeon located in Cape Coral [Bonita Springs and Lehigh Acres]. He has been serving in Cape Coral for about 30 years and has grown to be world renowned.

    Dr. Croley enjoys a reputation, as a result of his professionalism and accomplishments, that serve to set him apart from any other in a delicate field. He’s a giving, feeling individual, dedicated to making better those things that serve to improve the quality of life in our society.

    Dr. Croley has now authored a fabulous book entitled “Believing is Seeing.” The book is designed to provide insights into how to improve one’s health and welfare in a complicated world….and does just that!

    I believe that a feature focusing on the life and times of this extraordinary man would represent a true community service.
    In line with the Doctor’s giving persona…proceeds from the book sales will be donated towards Missions.

    Happy Easter & God Bless,

    Dick
