percentage of blue eyes by country
Such albinos have pink eyes, as do albino rabbits, mice, or any other animal with a total lack of melanin. Almost all humans have some brown in their eyes. [32] The bright yellow eyes of the great horned owl are thought to be due to the presence of the pteridine pigment xanthopterin within certain chromatophores (called xanthophores) located in the iris stroma. [3]:9. If you have dark brown hair and brown eyes, you have something in common with most people around the globe. Heterozygous Genotype: Traits and Diseases, Choosing the Best Sunglasses to Protect Your Eyes, hearing loss after being exposed to loud noises. [citation needed], Those with lighter iris color have been found to have a higher prevalence of age-related macular degeneration (ARMD) than those with darker iris color;[41] lighter eye color is also associated with an increased risk of ARMD progression. Most Asian and African children are born with brown and black eyes. In the US, 45% of people have brown eyes, while the rarest eye color is green only 9% of people in the US have green eyes. In humans, this pigmentation of the iris depends on the melanin concentration in the iris pigment epithelium, it's content within the iris stroma, as well as the cellular density of the stroma. All blue-eyed people have one ancestor in common, born around 6,000 to 10,000 years ago. 2000-2023 AAV Media, LLC. Thats true for people of every eye color. [74][75][76] Eyes that appear red or violet under certain conditions due to albinism are less than 1 percent of the world's population. Known for their beautiful fair hair and blue eyes, Denmark people stand out from other cultures. The extensive study on the genetic mutation was carried out by researchers at three Japanese universities; the research concluded that the genetic mutation occurred around 9,000 BC, as a result of various environmental and evolutionary factors. Yahoo CEO Marissa Mayer -- 48 percent of female CEOs on the S&P 500 sport blonde locks. Indeed, one study found evidence of blue-eyed hunters and gatherers roaming Spain 7,000 years ago. Transillumination defects can almost always be observed during an eye examination due to lack of iridial pigmentation. [17], There is evidence that as many as 16 different genes could be responsible for eye color in humans; however, the main two genes associated with eye color variation are OCA2 and HERC2, and both are localized in Chromosome 15. Especially, Intraocular Melanoma. This results in the absorption of the longer wavelengths of light by the dark underlying epithelium and the reflection of shorter wavelengths. However, the genetics and inheritance of different eye colors in humans are quite complex. All maps, graphics, flags, photos and original descriptions 2023 worldatlas.com. Vika is the story of her final year at a rural boarding school in Eastern Ukraine. Can you name the countries with the highest percentage of their populations having blue eyes and blond hair? International Journal of Ophthalmology. Brown-eyed individuals, on the other hand, have a lot more variation. [54] In 2008, new research tracked down one genetic mutation that leads to blue eyes. Comments. Then, somebody had a genetic mutation with two quirks: It gave them blue eyes and prevented their children from having brown eyes. Keep that 70-79% global estimate for brown eyes in mind when you look at the numbers below from a study in the journal Forensic Science International: Genetics.. Sitting sixth on this list, Denmark 's population is 60 percent blue-eyed. If you see a dark outline around your iris -- the colored part of your eye -- this is your limbal ring. The color of our eyes depends on how much melanin is present in the iris. There are two main genes on chromosome 15 that determine a person's eye color: OCA2 and HERC2. The highest percentages of fair-haired people can be found around the Baltic Sea (e.g. And when you meet a red head with blue eyes, you are looking at the rarest colour combination of all for human beings.

The top layer, called the epithelium, is where the melanin (pigment) that gives an eye its color lives. So, the more melanin you have, the darker your eyes appear. In the US only 1 out of 6 people have a light (blue) eye colour. Sitting sixth on this list, Denmark's population is 60 percent blue-eyed. Additionally, Icelanders are very passionate about supporting their sports teams! Having blue eyes has its advantages. Similarly, people with hazel, gray and green eyes have varying quantities of tint in the front layer. Plus, although this cancer is extremely rare, light-eyed folks are also more susceptible to sun damage from exposure to UV rays. [19] Approximately 27% of people in the United States and between 8% and 10% of the world's population have blue eyes. Its been suggested that the cooler climate of northern Europe may have encouraged the rise of a population of people with lighter eyes, hair and skin. Different SNPs within OCA2 are strongly associated with blue and green eyes as well as variations in freckling, mole counts, hair and skin tone. To put that in perspective, 79% of people have brown eyes. Anisocoria thus refers to an abnormal condition characterized by different pupil sizes. So, if melanocytes extract just a little bit of melanin, babys eye color will remain light, but they usually produce much more of this protein, which causes darker eye colors. People with blue eyes have a single, common ancestor, according to new research. Some speculate that this change in environment was a contributing factor. This can make the blue eyes look slightly different depending on the type of lighting conditions. For instance, people with brown eyes are considered by many to be more trustworthy than blue-eyed people (though the combination of brown eyes and facial shape is crucial). In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma. Grndl M, Knoll S, Eisenmann-Klein M, Prantl L. The blue-eyes stereotype: do eye color, pupil diameter, and scleral color affect attractiveness? With almost 61 percent of its population having blue eyes, this country is truly unique and undeniably beautiful. The polymorphisms may be in an OCA2 regulatory sequence, where they may influence the expression of the gene product, which in turn affects pigmentation. Brown is the most common eye color in the United States, just as it is globally. Persons with albinism have very little or no melanin in the iris. Although people with lighter eye color are generally more sensitive to light because they have less pigment in the iris to protect them from sunlight, there is little to no evidence that eye color has a direct impact on vision qualities such as visual acuity. If this gene activation never happens, a baby's eyes will stay blue. Eyes only appear to be these colors because of the way light strikes the layers of the iris and reflects back toward the viewer. [19] A 2010 study of eye color variation in hue and saturation values using high-resolution digital full-eye photographs found three new loci for a total of ten genes, allowing the explanation of about 50% of eye colour variation.[20]. This form of hearing loss comes from damage to the inner ear or to the nerve going from the ear to the brain. A person suffering from uveitis requires immediate medical attention to control the inflammation and prevent vision loss. Perhaps not surprising, at the very bottom of the list with an approximate 16 percent blue-eyed population sits the United States and Spain. 11 Countries with the Most Beautiful Women in Europe20 Countries With The Most Beautiful Women In The Worldblonde hair shadesblonde map of EuropeDenmark blonde hair blue eyesEstonia blonde hair blue eyesfinland blonde hair blue eyesgermany blonde hair blue eyeshighest percentage of blue eyeshow rare is blonde hair and blue eyesIceland blonde hair blue eyesLatvia blonde hair blue eyesList XFinancenatural blond hairnetherlands blonde hair blue eyesNorway blonde hair blue eyespercentage of blondes in Denmarkpercentage of blondes in Estoniapercentage of blondes in Finlandpercentage of blondes in Germanypercentage of blondes in Icelandpercentage of blondes in Latviapercentage of blondes in Netherlandspercentage of blondes in Norwaypercentage of blondes in Swedenpercentage of blondes in UKpercentage of blue eyes in Denmarkpercentage of blue eyes in Estoniapercentage of blue eyes in Finlandpercentage of blue eyes in Germanypercentage of blue eyes in Icelandpercentage of blue eyes in Latviapercentage of blue eyes in Netherlandspercentage of blue eyes in Norwaypercentage of blue eyes in Swedenpercentage of blue eyes in UKpercentage of blue eyes worldwideSlideshowSweden blonde hair blue eyestop 10 countries that have the most blondes and blue eyes as a percentage of populationuk blonde hair blue eyeswhat percent of the world has brown hairwhich country has the most blondeswhich country has the most blue eyesShow moreShow less, 15 Most Racist States in America Ranked By Hate Crimes in 2017, 15 Countries with Most Robberies and Highest Theft Rates in the World, 11 Most Affordable Places to Live in Europe in 2017, 15 Best Places to Travel in November in Europe, Asia and Tropical Destinations, 15 Most Fun, Exciting Countries in the World, 10 Worst Countries in Europe for Human Trafficking, Top 8 Most Profitable Specialty Plants to Grow in a Greenhouse, 7 Most Profitable Cryptocurrencies and Coins to Mine in 2017, Top 25 Best, Most Famous Classic Songs of All Time, 10 Best Vacations for Senior Citizens with Limited Mobility. Protecting your eyes and getting regular check ups is important no matter the color of your irises. For example, Asians typically have brown eyes, while Europeans are more likely to have eyes of blue or other lighter hues. Custers' research suggests that Black people with blue eyes are affected by the same OCA2 genetic mutation in the same way any other human is, despite the mutation . One possible explanation for the difference in the appearance of gray and blue eyes is that gray eyes have larger deposits of collagen in the stroma, so that the light that is reflected from the epithelium undergoes Mie scattering (which is not strongly frequency-dependent) rather than Rayleigh scattering (in which shorter wavelengths of light are scattered more). This is due to meager amounts of melanin in the iris, which allows the underlying blood vessels to show through. Green eyes are common in Europe's Central, Western, and Northern regions. Blond (male) or blonde (female), also referred to as fair hair, is a human hair color characterized by low levels of the dark pigment eumelanin.The resultant visible hue depends on various factors, but always has some yellowish color. Viking stereotypes for being tall, strong, blond and blue-eyed are confirmed at least for the last two matters in the case of Denmark. [73], Although the deep blue eyes of some people such as Elizabeth Taylor can appear purple or violet at certain times, "true" violet-colored eyes occur only due to albinism.

Common Eye Disorders. Stay Safe. Most newborn babies who have European ancestry have light-colored eyes. 15 Best Places to Travel in November in Europe, Asia and Tropical Destinations 15 Most Expensive Items You Can Buy on Amazon. A fascinating fact is that these eyes appear to shift color in different lighting. Rather than including a blue pigment, they actually just lack the pigment that makes eyes brown. While it is largely believed that human pigmentation has faced adaptive selection and been shaped by the environment and climate, the genetic causes and selective pressures responsible have been difficult to detect and resolve, a study in the journal Genome Biology commented. Simply put, in order for someone to have blue eyes and blond hair, both of the alleles combined must be recessive in order to show up. The blue-eyes stereotype: do eye color, pupil diameter, and scleral color affect attractiveness?

In fact, over 80 percent of the inhabitants of Estonia . [3][6] This is an example of structural color, which depends on the lighting conditions, especially for lighter-colored eyes. Blue is the most common eye colour in Britain, researchers found. Through the analysis of ancient DNA, a 2020 study published in Experimental Dermatology suggested that the common gene for blue eye color likely originated in the Near East and arrived in Europe around 42,000 years ago, after the exodus out of Africa. Genetic research suggests that until about 10,000 years ago, pretty much everyone had brown eyes. Nevertheless, both figures leave Estonia among the top countries that have the most blondes and blue eyes as a percentage of population. An iris with little melanin appears blue, while those with more little melanin appear green or hazel. Scientists believe that all blue-eyed people can be traced back to a common ancestor, who probably had a genetic mutation that reduced their melanin in the iris. 3. Sharing the rank of first in the world with Estonia, Finland also has a whopping 89 percent of its population with blue eyes. The AAO states that those with central heterochromia have iris with two differently colored rings, while those with complete heterochromia have one iris with a different color.

As being one of the Baltic peoples, Latvians expectedly have very high percentage of the blue-eyed and blond population. One more usual hair color is red, and also green eye color, being among the rarest in the world. Former U.S. Geneticists now know that as many as 16 different genes influence eye color to some degree far from the one or two genes that were once believed to determine iris hue. With a 75.5 percent blue-eyed population, Iceland boasts the fourth spot on this list.
