Quick Take
A social media post claims that eye colour of a person can be changed after consuming a raw vegan diet or detox or a herb called contribo. We fact-checked and found this claim to be False.
The Claim
In a Facebook video, the narrator states that eyes can change color if you detox the body from the heavy metals, toxins and diseases, consume a raw fruit diet or fast for a period of time or take specific herbs, such as contribo that detox the body and bring oxygen to your brain.

Fact Check
How is the eye color determined?
The color of eyes is determined by the combination of genetic factors inherited from their parents. Eye color is primarily influenced by the amount and distribution of a pigment called melanin in the iris. It is the colored part of the eye. Melanin comes in three forms: eumelanin, pheomelanin, and neuromelanin.
The specific genes involved in eye color inheritance are complex and not fully understood. However, it is known that multiple genes play a role in determining eye color. Variations in the OCA2 gene, as well as other genes such as HERC2, can influence the amount and type of melanin in the iris, resulting in different eye colors.
The inheritance of eye color follows a complex pattern. It is generally believed that brown eye color is dominant over blue or green eye color. However, the actual inheritance can be more intricate, as other genetic factors and interactions between genes can influence eye color inheritance. It is possible for parents with brown eyes to have a child with blue or green eyes if they carry certain genetic variations that affect eye color.
It’s important to note that eye color can also be influenced by other factors, such as lighting conditions, the scattering of light in the iris, diseases, medications and trauma.
Can eye color of a person change after consuming a raw vegan diet or detox or a herb called contribo?
No. There is no scientific evidence to support the claim that eye color can change after consuming a raw vegan diet, detox, or the herb contribo. Eye color is determined by the amount of melanin in the iris, and there is no known way to change the amount of melanin in the iris through diet or supplements. Even no evidence confirms that eyes predict disease.
Even if some people claim that their eye color has changed after consuming a raw vegan diet or detox, it is impossible to know whether this is due to the diet or detox. It is possible that the eye color changed naturally over time, or that they suffer from a disease which might have led to the change. Also, while certain factors like lighting conditions or pupil dilation can create the illusion of temporary changes in eye color, these changes are not permanent and do not alter the underlying genetic makeup or pigmentation of the iris.
Can the eye color of a person change?
Not exactly. In most cases, the eye color of a person remains stable throughout their lifetime. However, there are a few rare instances where eye color can change or appear to change. Here are some possible reasons for such changes:
- Age: In babies, the pigmentation of the iris may not be fully developed at birth. It is common for babies to have blue or gray eyes that may darken or change in the first few years of life as more melanin is produced.
- Lighting and environment: Eye color can appear to change depending on the lighting conditions and surroundings. Different lighting can affect the appearance of the iris, making the eye color appear lighter or darker. For example, someone with green eyes may appear to have hazel eyes in certain lighting conditions.
- Disease or medical conditions: Certain medical conditions, such as ocular albinism or Horner’s syndrome, can cause changes in eye color. These conditions affect the production, distribution, or presence of melanin in the iris, leading to alterations in eye color.
- Medications: In some cases, certain medications, such as prostaglandin analogs used for glaucoma treatment, have been known to cause changes in eye color. These medications can stimulate the production of melanin in the iris, resulting in a darkening of the eye color.
- Heterochromia: It is a condition where a person has two different eye colors. It can be present from birth or develop later in life. Heterochromia can be caused by genetic factors, eye injuries, certain diseases, or even as a side effect of certain medications.
It’s important to note that significant and spontaneous changes in eye color are relatively rare and should be evaluated by an eye care professional to rule out any underlying medical conditions or eye disorders.
