More than 50% of people worldwide have brown eyes, making brown the most common eye color. Learn more fun facts about eye colors and what they may signal about your health. Share on Pinterest ohlamour studio/Stocksy United The colored part of your eye is called the iris. Its color comes from melanin, the same pigment that determines skin color. Different eye colors are the result of different amounts of melanin. Today, brown is the most common eye color worldwide. According to the American Academy of Ophthalmology (AAO), at one time, all humans had brown eyes. Then, a common ancestor experienced a gene change that led their descendants’ eyes to produce less melanin. Melanin can protect the eyes from sun damage. That may explain why brown eyes are more common in hotter climates throughout Asia and Africa. What are eye color percentages around the world? It’s challenging to determine the number of people with a certain eye color. To start, researchers have changed the color categories over time. Some have included gray, blue, brown, and black, while others have also used categories like pale yellow and deep yellow. A 2015 Canadian study on eye color in young adults noted that there has been little research on the genetic basis of eye color in people of non-European ancestry. The authors also stated that although brown eyes are dominant outside of Europe, there’s extensive variation within that brown color. “Brown” eyes can range from a light reddish-yellow to a dark brownish-black. Over 50% of the world’s population has brown eyes, according to the AAO. Just around 2% of people worldwide have green eyes. In the United States One 2014 survey asked over 2,000 people in the United States about their eye color. According to the AAO, the survey data can be used to determine eye color prevalence across the country at large. Brown is the most common eye color in the United States, just as it is globally. Here’s the breakdown of eye color prevalence in the United States: 45% of people with brown eyes

27% with blue eyes

18% with hazel eyes

9% with green eyes

1% with eyes of another color In Africa Most people of African descent have brown eyes, according to a 2021 literature review . In South Asia and East Asia The 2015 study mentioned earlier found that almost all study participants representing South Asia and East Asia had brown eyes. Participants were categorized as South Asian if all of their grandparents had Bangladeshi, Indian, Pakistani, or Sri Lankan ancestry. East Asian participants had grandparents with Chinese, Japanese, Korean, or Taiwanese ancestry. There was slightly more eye color variation among South Asian participants than East Asian participants. Few East Asian participants had green eyes, while none had blue eyes. Other research has also concluded that most Asian people have brown eyes. In Europe and Central Asia A 2019 literature review on eye and hair colors included data on eye colors for countries across Europe and Central Asia. The review used the broad categories of “brown,” “intermediate,” and “blue.” Here are statistics for a few of those countries: Country Percentage with “brown” eyes

(2019). True colors: A literature review on the spatial distribution of eye and hair pigmentation. https://www.fsigenetics.com/article/S1872-4973(18)30338-7/fulltext How is eye color determined? Scientists used to think your eye color was determined by two eye color genes, one from each parent. Since the gene for brown is dominant over blue, the belief was a blue-eyed person would have two genes for blue eyes, and two blue-eyed parents couldn’t have a brown-eyed child. We now know that it’s much more complicated than that. According to an older 2010 study, your eye color is determined by up to 16 genes that control melanin production in your iris. Melanin absorbs light. When an object absorbs light, it looks dark. When it doesn’t absorb light, the light is reflected, and the object is the color of the light it reflects. Light reflected from your eye comes from the blue part of the color spectrum. Brown eyes have a lot of melanin, so they absorb light, which makes them dark. Hazel eyes have less melanin than brown eyes but more than green eyes. Blue eyes have the least amount of melanin and reflect the most light. Because you inherit genes from your parents, your eyes will likely be similar in color to their eye colors. It’s also possible for you to have brown eyes even if both of your parents have blue eyes. Heterochromia, or different-colored eyes If you have heterochromia, all or part of one iris is a different color than the other iris. Heterochromia can be the result of: heredity

various medical conditions, including: bleeding in the eye ocular melanosis, a type of lesion that may be benign or cancerous tumors of the iris diabetes Can you change your eye color? Because reflected light determines eye color, blue, green, and hazel eyes can look slightly different under different lighting conditions. However, once your eye color is set in childhood, your eyes can’t naturally change to a completely different color. Babies are the exception. Melanocytes, which are specialized cells that secrete melanin, are most active in the first year of life. This means eye color is usually determined by age 1 year. However, changes in eye color begin to slow down once a baby reaches 6 months old. You can artificially change your eye color, but it can be risky. Contact lenses You can accentuate, enhance, or completely change your eye color with contact lenses. Decorative, or costume, lenses come in a variety of colors and can correct vision or not. Note that it’s illegal to sell contact lenses, even decorative lenses, without a doctor’s prescription in the United States. Some hazards of wearing lenses that a doctor hasn’t prescribed or are otherwise ill-fitting include: cuts and scratches on the eye

Iris implant The iris implant is a surgical procedure originally developed to treat eye injuries and other conditions. It has also been used to permanently change eye color. In 2014, the AAO warned against undergoing this procedure for aesthetic reasons. Prescription medications (due to side effects) Some medications may permanently change the color of the eye over time, including: medications to treat glaucoma 0.03% bimatoprost ophthalmic solution (Latisse), an eyelash lengthener Glaucoma medications and Latisse contain prostaglandins, hormone-like compounds that may darken your eyes by a shade. Increased brown pigmentation in the iris is a possible, albeit rare, side effect of Latisse, according to the manufacturer’s website. Over-the-counter (OTC) products Some companies sell cosmetic products, like eye drops and balms, that promise to change your eye color. The Food and Drug Administration (FDA) hasn’t approved these products, and they may not come with any supporting evidence. Before investing in any such products and potentially risking your eye health, consider seeing an optometrist.
