The most common characteristic thought to be associated with blue-eyed individuals: exuding sweetness by (42 percent), with being sexy (21 percent) and kind (10 percent) rounding out the top three.
blue eyes descend from a single genetic mutation means that every single person on the planet with blue eyes descended from one common ancestor. In fact, a team of geneticists at the University of Copenhagen actually traced that mutation all the way back to a single Danish family.
Blue eyes are more sensitive to light. Those who have blue eyes are more commonly strategic thinkers. People with blue eyes are 12% more likely to develop diabetes than people with other eye colors. Those who are born with blue eyes are susceptible to developing a skin condition that's known as vitiligo.
Does eye color have an effect on intelligence? The above study found that 34% of participants considered people with brown eyes intelligent, kind, and trustworthy. In contrast, people with blue eyes were considered kind, sweet, and sexy, but only 7% of participants described blue-eyed people as intelligent.
Grey eyed people scored the highest with the remaining colors close behind.
People with grey eyes are perceived to be the smartest. Blue-eyed people are seen as being the most expressive. Those with green eyes are deemed adventurous. Brown eyes are perceived the most kind.

Europe has the widest variety of eye color, according to Custers, who adds those of European descent are the largest population of blue eyes. Europe was the epicenter of the blue-eye gene mutation. More than 80 percent of the inhabitants of Estonia and Scandinavian countries have blue eyes.
Scientists believe that it is possible to trace all blue-eyed people back to a common ancestor, who likely had a genetic mutation that reduced the amount of melanin in the iris. Most people with blue eyes are of European descent.
"Originally, we all had brown eyes," said Hans Eiberg, associate professor in the Department of Cellular and Molecular Medicine at the university. "But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a 'switch,' which literally turned off the ability to produce brown eyes."
World Atlas notes that only 8% to 10% of the global population has blue eyes. Violet eyes are even rarer, but they're a bit misleading; someone with “violet” irises is usually sporting a special shade of blue.
People who are born blue-eyed are at higher risk of developing age-related macular degeneration. The research shows that there is less pigment in blue eyes, and green eyes for that matter, than there is in brown eyes. This means more light is able to penetrate blue eyes. This makes lighter eyes more sensitive to light.
"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."
“The mutations responsible for blue eye colour most likely originate from the north-west part of the Black Sea region, where the great agricultural migration of the northern part of Europe took place in the Neolithic periods about 6,000 to 10,000 years ago,” the researchers report in the journal Human Genetics….
Blue-eyed? Thank a genetic switch that turns off your body's ability to make brown pigment in your peepers. Researchers have finally located the mutation that causes blue eyes, and the findings suggest that all blue-eyed humans share a single common ancestor born 6000 to 10,000 years ago.
The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
In 2006, researchers discovered a 7,000 year old body from the Stone Age in the La Brana cave system in Leon in Northern Spain (Image 4). Genetic testing determined that this man had blue eyes. It was not in itself unusual, but what is remarkable is that he is the earliest known person with blue eyes.
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 is the most attractive eye color? Despite songs about blue eyes and brown-eyed girls, neither were found to be the most attractive eye color. Instead, gray eyes topped the chart with an average rating of 7.4, followed by blue and green eyes each scoring an average of 7.3.
The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive. Given this information, you can determine what eye colors are dominant in the parents.
An individual's eyes can reveal a lot about them, including their mood, feelings, and even emotions. By simply looking at them, eyes can convey a warm, bright, and inviting vibe as well as a cold and repellent one – they are the window to a person's soul.
Those with darker colored eyes experience less visual discomfort in bright, sunny conditions. Also, darker irises reflect less light within the eye, reducing susceptibility to glare and improving contrast discernment—so people with darker eyes may have better vision in high-glare situations, such as driving at night.
Blue: Intellectual
Blue is a soothing color, helping calm the mind and aid concentration. It's no wonder then that blue is a popular color to use in office spaces. It enhances wakefulness and supports clear communication.
Brown eye color personality is found to be more trustworthy, hazel eye color personality is determined and strong-willed, blue eye color personality is sentimental, green eye color personality is mysterious, grey eye color personality is more reserved, and black eye color personality is impulsive.
The Australian Shepherd is one of a few dog breeds that commonly have two different colored eyes, called heterochromia. 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.
