There are many claims that a raw vegan diet can change eye colour, with some people stating that their eyes have changed from brown to blue, or hazel to green. However, there is little evidence to support these claims. Eye experts and iridologists have stated that the idea of eye colour changing due to diet is weird and problematic. While some people have reported brighter or lighter eyes after adopting a raw vegan diet, this could be due to factors other than diet, such as age, lifestyle changes, or lighting conditions when taking photos. Additionally, it's important to note that eye colour is largely determined by genetics, and while diet may influence pigmentation, it is unlikely to cause significant changes in eye colour.

| Can a raw vegan diet change eye color? | There is little proof that a raw vegan diet can change eye color. Some people claim that their eyes have changed color, from brown to blue, or from brown to light brown with a green tint, but eye experts and iridologists say that this is unlikely. |
| What causes eye color to change? | Eye color can change slightly throughout a person's lifetime, especially in babies and young children, whose eyes are typically lighter and clearer. As people age, their eyes may also change, with some people developing more pigmentation in their eyes as they get older. |
| Can diet affect eye color? | It is possible that diet can affect eye color, but the effect is likely to be minimal. Eating large quantities of certain nutrients can affect melanin production, which colors our skin, hair, and eyes. For example, consuming a lot of beta carotene can turn the skin orange, and eating large amounts of dark leafy greens can lead to a greenish tint in the eyes. |
| Why do some people believe that a raw vegan diet changes their eye color? | Some people associate blue or light-colored eyes with a "clean" or "pure" body, and believe that a raw vegan diet can lead to improved health and detoxification. Iridology, the study of the iris, suggests that the markings in the eye can indicate the health of various organs in the body. |

What You'll Learn
Iridology suggests that the iris reflects organ health
Iridology is based on the scientific study of the iris, the coloured part of the eye. It involves examining the colour, fibre structure, pigmentation, and other markings on the iris. The iris is divided into multiple zones, each of which is said to represent a different organ or part of the body. According to iridology, the iris reflects physiological conditions, health risks, challenges, and strengths of various organs. For example, the top quadrant of each eye is related to brain health, and the innermost circle of the eye is related to digestion. Iridologists claim they can use charts to distinguish between healthy organs and those that are inflamed or distressed.
The concept of observing the eyes for health insights can be traced back to ancient Egypt, China, and Greece. Hippocrates, the "Father of Medicine", mentioned using the eyes as a window to the body's health. Modern iridology is often attributed to 19th-century Hungarian physician Ignaz von Peczely, who is said to have noticed a correlation between a leg injury to an owl and a mark in its iris. However, his nephew later dismissed this story as a myth. Another important figure in the history of iridology is Nils Liljequist from Sweden, who observed changes in the colour of his iris after a round of medication.
Iridology is still considered controversial and has been called pseudoscience. A 2005 study tested the usefulness of iridology in diagnosing common forms of cancer and concluded that "iridology was of no value in diagnosing the cancers investigated in this study". Another study published in the British Medical Journal found that iridologists could not correctly identify which patients had gallbladder problems and which had healthy gallbladders. However, some professionals feel that iridology can be a very useful tool to detect many health conditions.
While iridology may not be able to diagnose specific diseases, some health practitioners say it helps them determine which organs and systems in the body are under stress and may be at risk of developing specific conditions. For example, an iridologist may be able to discover that other seemingly unrelated health concerns have underlying digestive problems. Iridologists use the blood vessels in the whites of the eyes to discover environmental and food allergies and sensitivities. They can also discover some markers of inflammation, which can be a prelude to serious health conditions such as autoimmune diseases.

Detoxification may cause eye colour changes
There is little evidence to suggest that a raw vegan diet can change eye colour. Most iridologists believe that the colour of one's eyes is fixed by the late teens to early 20s and remains the same throughout life. However, some iridologists acknowledge that eye colour can change slightly with age, and that detoxification may play a role in these changes.
Iridology is the scientific study of the iris, which is based on the belief that the markings in the iris reveal physiological conditions, health risks, and the strengths and weaknesses of various organs. Iridologists who support the idea of detoxification-induced eye colour changes argue that the colour, clearness, and clarity of the eyes reflect the cleanliness and health of the body. They claim that a raw, plant-based diet can improve digestion and reduce constipation, thereby reducing the toxic load in the body. This reduction in toxins can allegedly lead to changes in eye colour, making the eyes appear brighter, lighter, or clearer.
For example, a person with brown eyes may notice a slight lightening or development of a greenish tint around the iris. This is attributed to the dissipation of layers of coloration as the body becomes "cleaner" through detoxification. Additionally, the release of accumulated uric acid waste by the kidneys can reduce the yellow hue in the eyes, making them appear more blue.
However, it is important to note that there is scepticism within the field of iridology regarding these claims. Some iridologists maintain that eye colour changes due to diet are a misconception and that any perceived changes are likely due to age or other factors. Furthermore, there is no scientific evidence to support the idea that eye colour changes are inherently positive, and sudden changes in eye colour can sometimes indicate underlying health issues.
While there are anecdotal reports of eye colour changes while on a raw vegan diet, there is currently insufficient scientific evidence to confirm a direct causal relationship. The role of detoxification in eye colour changes remains speculative and requires further research.

A raw diet may only make eyes appear brighter
There is little evidence to suggest that a raw vegan diet can change eye colour. Iridologists, eye experts, and other commentators have expressed scepticism about the idea. One iridologist, Yvonne Davis, states that "most iridologists believe the colour of your eyes really can’t and doesn’t change that much". She adds that, while eyes can change colour naturally until a person reaches their late teens or early 20s, and can also change slightly with age, these changes are unrelated to diet.
However, some people who follow a raw vegan diet have claimed that their eye colour has changed as a result. One person, who had previously had dark green eyes with brown specks, reported that their eyes changed to a light grey-blue with green hints and a brown ring around the iris after six years of eating raw vegan. Another person, who had previously had hazel eyes, reported that their eye colour changed to a bluish-greenish hue with some brown specks after six months of eating raw.
Some have theorised that a raw vegan diet may only make eyes appear brighter, rather than changing their colour. One Reddit user suggests that this is because the whites of the eyes become clearer, creating the appearance of brighter eyes. Another Reddit user notes that certain pigments like lutein and zeaxanthin can build up behind the eye, which could theoretically affect eye colouration, albeit only slightly.
It is worth noting that some commentators have expressed concern about the emphasis on eye colour change as a sign of health or purity. One article notes that there is no evidence to suggest that eye colour change is a good thing, and that it can actually indicate serious health issues such as Horner's syndrome and pigment dispersion syndrome.

Large quantities of certain foods may affect eye colour
While there is little scientific evidence that a raw food diet can change eye colour, some people claim that their eyes have changed colour after adopting a raw vegan diet. Some people have reported that their eyes changed from brown to blue, or from brown to light brown with a green circle around the iris. Others have noticed a slight increase in the greenish hue of their eyes.
Some people believe that a raw vegan diet can create the appearance of brighter eyes. One possible explanation for this is that certain pigments like lutein and zeaxanthin build up behind the eye, which could theoretically affect eye colouration, albeit slightly.
Iridologists, or proponents of iridology—the scientific study of the iris—believe that the eye colour changes observed in some people on a raw vegan diet are unrelated to their dietary choices. Instead, they attribute these changes to age, with the eye colour stabilising by the late teens to early 20s, and slight variations occurring in older adults due to lifestyle changes or increased pigmentation.
It is important to note that large quantities of certain foods may affect eye colour. For example, consuming huge amounts of beta carotene can turn the skin orange, and excessive intake of dark leafy greens can lead to greenish tints in the eyes. However, these changes are not inherent to a raw vegan diet and require excessive consumption of specific foods.
In conclusion, while some individuals assert that their eye colour has changed due to a raw vegan diet, there is limited scientific evidence to support this claim. The observed changes could be attributed to factors such as age, lifestyle modifications, or increased consumption of specific nutrients.

Eye colour changes are linked to changes in melanin
Eye colour is influenced by multiple genetic and biological factors. Melanin, the primary pigment found in the iris, plays a crucial role in determining eye colour. The amount and distribution of melanin within the iris influence whether eyes appear brown, blue, green, or other shades. Melanin is produced by melanocytes, specialized cells within the iris. Brown eyes have the highest concentration of melanin, while blue eyes have a very low melanin content in the iris.
The iris reveals physiological conditions, health risks, and the strengths and weaknesses of various organs. For example, the top quadrant of each eye is related to brain health, while the innermost circle of the eye is related to digestion.
Some people who follow a raw vegan diet have reported changes in their eye colour, ranging from slight lightening to more noticeable shifts from brown to blue. However, eye experts and iridologists generally refute these claims, stating that while diet can slightly affect eye colour, it is primarily determined by genetics and remains relatively stable throughout life.
While there is limited evidence of significant eye colour changes due to diet, certain medical conditions and factors can cause noticeable alterations. For instance, Fuchs Heterochromic Iridocyclitis (FHI) is an inflammation that can cause a loss of iris pigmentation, leading to a change in eye colour. Additionally, long-term sun exposure can cause a slight darkening of the eyes, and certain medications can lead to permanent darkening as well.
In summary, while eye colour changes due to a raw vegan diet are largely unsubstantiated, alterations in eye colour are indeed linked to changes in melanin levels, which can be influenced by various medical conditions, sun exposure, and, in rare cases, specific medications.

Frequently asked questions
No, not everyone on a raw diet experiences a change in eye color. While some people have claimed that their eye color has changed from brown to blue, or brown to light brown with a green circle, there is little proof that a raw diet can change eye color.
The change in eye color is often attributed to the detoxification and purification associated with a raw diet. Some believe that as the body clears up toxins, the eyes reflect this change and appear lighter or brighter.
There is limited scientific evidence to support the claim that a raw diet can change eye color. Iridology, the study of the iris, suggests that the markings on the iris reflect physiological conditions, including health risks and organ health. However, eye experts and iridologists generally disagree with the notion that diet alone can significantly alter eye color.
Yes, it is important to note that changing eye color is not necessarily a positive or healthy development. While some people associate lighter eye colors with purity or improved health, there is no evidence to support these claims. Additionally, changes in eye color can be a sign of underlying medical conditions, such as Horner's syndrome or pigment dispersion syndrome.
Yes, genetics plays a significant role in determining eye color. While diet and detoxification may have some influence, the color of one's eyes is primarily determined by genetic factors, which vary across different ethnic groups.
