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.
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.
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.
"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."
People with brown eyes are said to be independent, determined and self-confident. Yet, you never fail to remain humble. When people look at you, they get a sense of security and stability – you are known to be trustworthy. While you may want to act tough, your brown eyes portray how kind and sensitive you truly are.
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.
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.
Rarest Eye Colour – Green.
For Aboriginal and Torres Strait Islander people, avoidance of eye contact is customarily a gesture of respect. In Western society averting gaze can be viewed as being dishonest, rude Page 2 or showing lack of interest.
Brown Eyes are the Most Common Eye Color
The overwhelming majority of people in Asia, Africa, and the Middle East have brown eyes. In Europe, it varies by region: eye color tends to be lighter in Northern Europe versus the South. In the United States, people with brown eyes comprise 41% of the population.
The lack of melanin makes the fibers scatter and absorb the longer wavelengths of light. This means that it is not true that under brown eyes there are blue ones but instead that under blue eyes, and all eye colors, they are actually brown.
It all comes down to genetics. Those two different eye colors, which is also known as wall eye, is one trait of many in dogs that their mother and father canine can pass down. With two parents, a puppy's gene copies double. Sometimes, these genes conflict with one another.
Benefits of Brown Eyes
People with brown eyes tend to be at lower risk for eye cancer, macular degeneration, and diabetic retinopathy. An additional benefit of brown eyes is that the higher melanin levels may protect the brain's nerves from damage due to noise.
Brown eyes have the highest amount of the pigment melanin in the iris. Lighter color eyes have less melanin. This reduced pigmentation affects how they reflect light and can make them appear blue, green, amber, or hazel. People with red or violet eyes have little or no melanin in their irises.
Green, yellow, orange, and red hues also show off the beauty of brown eyes. And bold colors that pop are a safe bet. Green and purple brighten up light brown eyes. Light eyelids are perfect for making your eyes shine.
Eye Color Changes Not Related to the Iris
Arcus senilis is a hazy blue or white ring on the cornea from a build-up of a natural fatty substance called lipids. It's common with aging and usually harmless. Most seniors have some degree of arcus senilis.

Anyone can be born with hazel eyes, but it's most common in people of Brazilian, Middle Eastern, North African, or Spanish descent. When eyes are hazel, they are brown mixed with amber and green. In some cases, there are shades of gray, blue, and gold within the iris too. Brown eyes may also have some green in them.
Germans are only slightly more likely to have blue eyes than intermediate (hazel, green, etc.) or brown eyes.
While blue eyes used to be the least common colour and were seen as a rarity, 48% of the British population now have blue eyes. This is followed by green eyes at 30%, with a mere 22% of the British population having brown eyes.
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.
Conversely, brown eyes are the most common color yet the least attractive to the survey's respondents. According to World Atlas, approximately 79% of the world's population has brown eyes, making it the most common eye color in the world.
Intelligence was the number one trait associated with brown, the most common eye color in the U.S., by 34 percent of respondents.
