Can you change your eye colour naturally?

​Changing the eye colour can change

The colour of our eyes is a fascinating and unique trait, often capturing attention and curiosity. While some dream of having a different eye colour, the question arises: can you change your eye colour naturally? Here’s what you need to know.

​The science behind eye colour

Eye colour is determined by the amount of melanin in the iris, the coloured part of the eye. People with more melanin in their irises have darker eyes, while those with less melanin have lighter eyes, like blue or green. Genetics play a significant role in determining eye colour.

​Natural changes in eye colour

Natural changes in eye colour are typically subtle and gradual. Some factors that might cause slight variations include ageing, hormonal changes, and prolonged sun exposure. For example, up to 15% of Caucasians with lighter eye colours may notice a gradual change in their eye colour as they age.

​Medical conditions affecting eye colour

Certain medical conditions can cause changes in eye colour. For instance, Fuchs’ heterochromic iridocyclitis, a rare form of eye inflammation, can lead to a loss of pigmentation in the iris. Other conditions, such as Horner’s syndrome and pigmentary glaucoma, can also alter eye colour.

​Mood and eye colour

While emotional responses can cause the pupils to dilate or contract, affecting how the iris pigments are displayed, this does not result in a permanent colour change. The perceived change is more about lighting and the size of the pupil rather than an actual alteration of the iris.

​The role of sun exposure

Prolonged sun exposure can lead to an increase in melanin production in the eyes, potentially darkening the eye colour slightly. This is similar to how skin tans when exposed to the sun. However, the change is usually minimal.

​Is it a myth

Numerous myths suggest that eye colour can be changed naturally through diet, specific exercises, or herbal remedies. There is no scientific evidence to support these claims. The melanin content in your iris is genetically determined and cannot be altered by such methods.

​Cosmetic solutions

If you’re keen on changing your eye colour, the safest and most effective way is through coloured contact lenses. These come in various shades and can provide a temporary change in appearance without altering your natural eye colour.

Surgical procedures

Some people consider surgical procedures, like iris implants or laser treatments, to change their eye colour. These procedures are not approved in many countries, including the United States, due to significant risks such as glaucoma, cataracts, and even blindness.
