Your eyes are protected by a structure called the tear film. The tear film is 99% water, and can become dehydrated through pollution and a dry global environment. To protect and care for the tear film, it is important to know how the tear film is structured.
There are three layers of the tear film:
1. Lipid layer. The lipid layer is the top layer of the tear film and consists of a thin film of fatty oils that lubricate the eyelid, help protect the eye from airborne particles, and slow evaporation of water from the aqueous layer.
2. Aqueous layer. The aqueous layer is the middle, and thickest, tear film layer, and contains the vast majority of its water. It also contains electrolyte, beneficial proteins and enzymes, and bacteria-fighting antibodies.
3. Mucin layer. The mucin layer is the bottom layer and glues the tear film to the ocular surface.
It’s important to keep the eyes hydrated for tear film and vision health. Nature’s Tears EyeMist is a specially formulated all-natural eye mist that supplies the eye with needed moisture while not flooding the tear film.
Loss of moisture in the tear film can result in dry eye, which is the #1 reason for eye doctor visits in the United States.
