Brown eyes are common in Europe, East Asia, Southeast Asia, Central Asia, South Asia, West Asia, Oceania, Africa and the Americas. Light or medium-pigmented brown eyes can also be commonly found in South Europe, among the Americas, and parts of Central Asia, West Asia and South Asia.
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. The colored part of your eye is called the iris. Its color comes from melanin, the same pigment that determines skin color.
Australians of European ancestry have about 25 percent brown eyes while those of non-European descent almost all have brown eyes. If you include hazel eyes (sometimes called hazel brown eyes), the prevalence is even higher. This high prevalence doesn't mean all brown eyes look the same.
Brown Eyes: 45 percent.
Brown hair is common among populations in the Western world, especially among those from Northwestern Europe, Central Europe, Southeastern Europe, Eastern Europe, Southern Europe, Southern Cone,Brazil, Colombia, Costa Rica, Puerto Rico and the United States, and also some populations in the Middle East where it ...
Some eye shapes are immediately recognisable as belonging to a specific ethnic group – Asians, being the most obvious – but eye shape is otherwise not ethnicity-dependent.
Caucasians have the highest hair density among the ethnicities studied. Black people have the lowest. Asian people have hair density that falls somewhere in between.
"In Australians of European ancestry, the percentage of eye colours are 45 percent blue-grey, 30 percent green-hazel and 25 percent brown. If you're considering non-European ancestry it is the almost completely brown eye colour."
Interestingly enough, dark brown eyes are most common in Southeast Asia, East Asia and Africa. Light brown shades are most often seen in West Asia, Europe and the Americas.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
Aussies might have any combination of brown, blue, hazel, amber, or green eyes. Some Aussies even display more than one color within the same eye.
They Are Less Prone to Certain Eye Diseases
The sun can cause severe eye damage and result in eye diseases like cataracts and macular degeneration. But because brown eyes have more melanin, it's safe to say that if you have brown eyes, you are less likely to get these types of eye diseases.
Eye color doesn't significantly affect the sharpness of your vision, but it can affect visual comfort in certain situations. It all comes down to the density of the pigment melanin within your iris, which determines what colors of light are absorbed or reflected.
The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.
Brown eyes are the most common: Over half the people in the world have them, according to the AAO. In fact, about 10,000 years ago, all humans had brown eyes.
Originally, all humans had brown eyes. Some 6,000 to 10,000 years ago, a genetic mutation affecting one gene turned off the ability to produce enough melanin to color eyes brown causing blue eyes. This mutation arose in the OCA2 gene, the main gene responsible for determining eye color.
Your specific eye color depends on the amount of pigment present on the two surfaces of your iris. People with dark brown eyes have more melanin on the back layer of their iris, and eyes with very little (or no) melanin on the front layer of the iris appear more blue, green, or even hazel.
Brown eyes are far more common in people who live in warmer climates. This is because excess melanin (which causes the brown colors of the iris) protects the eyes from sunlight. Since warmer climates tend to have more sunlight, this means that brown eyes are more common in cultures near the equator.
Our breed standard allows eyes of any pigment color or combination of pigment colors. Aussie eyes have been seen that are golden, lemon yellow, amber, light brown, dark brown, green, orange, and blue. On very dark individuals they may even appear black.
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
What ethnicity has hazel eyes? Anyone can be born with hazel eyes, but it's most common in people of Brazilian, Middle Eastern, North African, or Spanish descent.
African Americans have the lowest hair density, averaging around 130 hairs per square centimeter and about 60,000 hair follicles on an adult scalp.
Certain races have higher rates of hair loss compared to others. Caucasians have the highest rates out of all the ethnic groups. On the opposite end of the spectrum, Native American Indians, Inuits, and Chinese have the lowest rates. Let's dive in deeper.
Racial gaps in life expectancy have long been recognized. The same CDC data show that nationally, Hispanic Americans have the longest life expectancy, followed by white and then Black Americans.
