Healthy tears are critical for maintaining the front surface of the eye and for providing clear vision

Healthy eyes are lubricated with an even layer of tears that serves as a protective film, called the tear film, to help to protect the cornea, which is the front surface of the eye. A healthy tear film consists of the right mix of oils, water, proteins, and mucus. Healthy tears and a healthy tear film are critical for support of the surface of the eye.

Are your eyes getting the omega-3 fatty acids they need?

Omega-3 fatty acids help support the eye’s tear film, by supporting the small glands on the edge of the eyelid, called the meibomian glands which help make the oil for the tear film.

Omega-3s are needed for healthy tears and optimal eye health, and also for exceptional overall health. Omega-3s are not produced by our body and must be obtained by diet or supplementation.

Dietary modifications with omega-3 fatty acids should be part of the first step for healthy tear support.

Most Americans don’t get enough omega-3 fatty acids, according to a study of the U.S. National Health and Nutrition Examination Survey, 2003–2008
