What Blue Eyes Mean?
- Pieter Maas
Whether you’re a brown-eyed girl or five-foot-two, eyes of blue, it’s what’s inside that counts. Seriously, we mean that. Your eye color has everything to do with your genetics, and if you’re blue eyed, you can probably figure out who’s a distant relative just by looking at them.
- It could be said that all eyes are the same color,
- That’s because the pigment that gives our eyes color, melanin, is naturally brown.
- In fact, originally, “we all had brown eyes,” a professor from the University of Copenhagen, Hans Rudolf Litchoff Eiberg, PhD, told Science Daily,
- Somewhere along the way, however, someone was born with a genetic mutation, Dr.
Eiberg explains. That genetic mutation limited the amount of melanin the person’s eyes could produce, with the visual effect being that the eyes appeared blue, rather than brown. Interesting, you might be thinking, but what do blue eyes genetics have to do with me? Well, the fact that all (so-called!) 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. “By linkage analysiswe fine-mapped the blue-eye color,” Dr. Eiberg’s team reported in the journal, Human Genetics, Through that analysis, it was discovered that an identifiable group of genes had been inherited together from one single parent—the scientific word for a group of genes inherited together from a single parent is ” haplotype,” The identified haplotype was common not just among 155 blue-eyed individuals from Denmark, but also five blue-eyed individuals from Turkey, and two blue-eyed individuals from Jordan.
In addition to haplotype mapping, Dr. Eiberg’s team conducted mitochondrial DNA analysis, which looks at patterns of genetic mutation to trace maternal ancestry back hundreds of thousands of years. “Variation in the color of the eyes from brown to green can all be explained by the amount of melanin in the iris, but blue-eyed individuals only have a small degree of variation in the amount of melanin in their eyes,” Dr.
- Eiberg notes.
- From this we can conclude that all blue-eyed individuals are linked to the same ancestorThey have all inherited the same switch at exactly the same spot in their DNA.” Brown-eyed individuals, by contrast, have considerable individual variation in the area of their DNA that controls melanin production.
So, are blue eyes a mutation? Yes. But is that a good thing or a bad thing? Neither, according to Dr. Eiberg. “It simply shows that nature is constantly shuffling the human genome, creating a genetic cocktail of human chromosomes and trying out different changes as it does so.” What we can presume, however, is that the color of our eyes is not the only thing trait that went along with the mutation that led to that color.

What does it mean to have a blue eye?
Naive; innocent; ingenuous.
Can eye color tell personality?
Are you generally quick-witted or able to solve problems at the snap of a finger? Or maybe you know how to handle your stress like a pro? Or perhaps you’ve got a really wicked backhand. If you relate to any of these, it could be due to the color of your eyes.
In fact, science has found that our eye color can tell us a lot about who we are and can help to determine our personality traits. We already know how much emotion the eyes can show, but it turns out that they also play a role in our personalities. A study conducted at the Orebro University in Sweden found that the genes responsible for forming our brains’ frontal lobes affect our eye color as well.
Because of this, the scientists reason, people with the same eye color may share personality traits. And that isn’t the only scientific study linking eye color to personality. Edinburgh University psychologist Dr. Anthony Fallone came to a similar conclusion when studying the subject.
- The eye is so closely linked neurologically to the brain that you might call it the only part of our brain you can see from the outside,” Dr.
- Fallone says.
- It seems to hold vital clues to our brain function.” Researchers have found that the color of our eyes may hold significant insight into our behaviors, mental health and tolerance to pain.

Home Lifestyle People With Blue Eyes Are More Attractive, Says Science
Beauty is in the eye of the beholder, and apparently things always come up looking blue. Credit: iStock / SanneBerg It looks like Frank Sinatra had it right this entire time. And while a lot of people might not agree with this at first, there’s a new report that says people with blue eyes are more attractive than their brown-eyed counterparts.
And yes, science does have something to do with the findings. Beauty is in the eye of the beholder, and apparently things always come up looking blue. A group of researchers at Germany’s University of Regensburg decided to do a study on which eye color is seen as more attractive: blue or brown? Researchers Martin Gründl, Sebastian Knoll, Marita Eisenmann-Klein, and Lukas Prantl asked 80 participants to rate the attractiveness of 60 women aged 15 to 65 by just looking at photos of their eyes.
And while there was no correlation found between iridal color and their rated attractiveness, the researchers did point out one thing: that the participants picked out the color blue more often as a positive aspect than other iridal colors. Also, those with large blue eyes usually have better luck in the love department: blue eyes and larger pupils often correlate with youthfulness, along with being attractive.

A third of the men found brown hair to be the most attractive; 28.6 percent said they prefer black hair.
In addition, the same study also found that men preferred women who had green eyes over those with brown eyes. Yet, the majority of both men and women found blue to be the most attractive eye color over all. If you happen to be a green-eyed beauty though, don’t fret. Reports say that the green eye color is the rarest color found around the world, and it is estimated that only around 2% of the world’s population has green colored eyes.
Green eye color is a result of a mild amount of pigmentation in the eye with a golden tint. But if there is one color that happens to be even more rare than green eyes, it’s violet. Elizabeth Taylor was famous for her violet eyes, although in reality she had baby blues.

High IQ: Bright Blue Eyes
- The colour of one’s eye may be the key to success.
- American scientists who conducted some tests concluded that brown-eyed people performed better at reaction time, but those with lighter or blue eyes appeared to be better strategic thinkers, the Daily Mail reported.
- Brown-eyed people succeeded in activities such as football and hockey, but lighter-eyed particpants proved to be more successful in activities that required skills in time structuring and planning such as golf, cross-country running and studying for exams, the scientists said.
- Louisville University professor Joanna Rowe, who conducted the tests, said the results suggested an unexplored link bet-ween eye colour and academic achievement.
“It is just observed, rather than explained,” she said. “There’s no scientific answer yet.”
- Bedfordshire University senior psychology lecturer Dr Tony Fal-lone, who has also studied eye colour, believed it should be taken more seriously as an indicator of personality and ability.
- Among the bright minds who have blue eyes are Stephen Hawking, Alexander Fleming, Marie Curie, Stephen Fry and Lily Cole.
- Stephen Hawking, the author of A Brief History Of Time, is Britain’s most eminent physicist.
- Biologist Alexander Fleming discovered penicillin and Marie Curie was the first twice-honoured Nobel laureate for her pioneering work on radioactivity.
- Writer and actor Stephen Fry is notoriously brainy, gaining a scholarship at Cambridge, and model Lily Cole recently secured a slot at King’s College in Cambridge after achieving five As in class.

Is blue the color of intellect?
Blue encourages intellectual activity, reasoning and logical thinking, and acquires lessons faster. That is the color of intellect. It has the power to help people adapt to new environments.
