Is it possible to change the color of your eyes through your diet? Claims have been made that some people experienced improved vision or else their eye color changed to blue or light gray due to their constant intake of raw food. There has been no scientific evidence to back up any claims of being able to change eye color due to diet.

Postulation of Brown and Blue Eyes

Blue eyes are said to be the healthiest, and brown eyes are seen as a sign that toxins are present in the body. But lots of raw food experts, alternative healers and some iridologists say that when an individual becomes healthier, the eyes become bluer or light gray. This can be a clear indication that some of the tissues throughout the body have improved. However, there have been no proven studies to provide solid evidence for such claims.

Possible Effects

As a side effect, raw food diets might improve circulation to flush out bad toxins from the body and in turn reform the pigments in the eyes. Such effects may cause people to experience a surprising change in their vision as well as their eye color. According to “Living and Raw Foods," the iris can change its pigment by the body regenerating new cells, but the topic is still being researched and needs more tested clinical studies to back up such claims.

Features of a Raw Diet Theory

The founder of Body Electronics, Dr. John Ray, says an all-raw diet is included in an energy-based and spiritual healing system in which some advocates have been observed to develop certain changes in eye color. However, there is no evidence to prove these claims. They say there is an overlaying discoloration caused by the toxins on the tissues in the iris, which can serve as a curtain-like cover that makes the iris look darker. No statements done by this private agency have been evaluated by the Department of Health and Human Services.


Eye colors may have nothing to do with toxins in the body, but it just may be hereditary traits from your genetics. Some people could make their eyes clearer from eating a raw diet, but may not change the color of their eyes. The only clinical way to permanently change eye color is through surgery. Eye color can also be temporarily changed through the use of contacts. The use of raw foods to change eye color is still under debate.


Perhaps most of the radical statements above are mere myths. Nonetheless, numerous practitioners adhere to the idea that an iris’ color may shift through green, blue and, finally, light gray due to a healing system based on raw food diet. However, the latter has not been adequately documented, and there have been no clinical studies done by the FDA to prove this matter. It is yet to be seen, and further evidence must be presented for it to be proven clinically.
