The Origin of Black People With Blue Eyes
People pay very little attention to common eye colors, which explains why I get very little to no compliments on my big brown peepers. We tend to be captivated by rare traits or unusual combinations such as black people with blue eyes.
Blues eyes are uncommon among blacks, especially those with no Caucasian ancestry, they almost always have brown eyes. Research has found that almost everyone with blue eyes is linked to an ancient genetic mutation. However, a small fraction get their blue eye color as a result of a health condition such as ocular albinism that affects pigmentation in the eye.
Take a look at some extreme examples of Black Africans and Black Americans with blue eyes.
Black Celebs With Blue Eyes
Michael Ealy is a film actor notorious for his charming looks and well known for his role in the movie Barbershop. He is my first example of a black Hollywood actor with blue eyes.
And finally, a few more Hollywood stars with blue eyes include:
- Chris Williams and his older sister Vanessa Williams
- actress Denise Vasi
Black Babies With Blue Eyes
Meet a black baby with blue eyes: Laren Galloway. He should be a lot older now, but these are some of the photos that made him famous. His surprisingly blue eyes are impossible to miss. As written on his blog, both of his parents are Black Americans.
We all love babies — most of us at least. Here are pictures of another black baby with blue eyes. He is called is Isaiah Chambers. Look closer: On top of his unusual blue eyes, it seems he has sectoral heterochromia. Did you notice the small brownish sections in his blue eyes?
Science has told us that eye color can change with age. There is therefore a small chance that those baby blues might start drifting away towards green, teal or even hazel as both children grow up. But I have a feeling Laren and Isaiah will be rocking their blue eyes for a very long time.
An African Child With Blue Eyes
How does it feel to be the only one in town with blue eyes? This African child surely knows all about it. His intense velvety blue eyes gave rise to the term “sapphire eyes”, due to their close resemblance to the blue sapphire.
Before you get skeptical about the authenticity of the "sapphire eyes", you should know that the picture wasn't photoshopped or altered in any way. As you can imagine, the photographer was immediately challenged when the picture was first published. She immediately rejected the idea and assured everyone that the picture was 100% authentic.
As we have seen so far on this page, there are quite a few black people with blue eyes. As long as Mother Nature is in charge, it is possible for anyone, irrespective of their ancestry to have any eye color. So place yours bets with caution, anything is possible when it comes to eye color.
With that said, let’s move on to an interesting story.
The Origin of People With Blue Eyes
A long time ago, everyone on this planet had brown eyes. The first light-eyed human emerged only about 10000 years ago, he or she had blue eyes. This story was told by Professor Hans Eiberg and his team of Danish scientists from the University of Copenhagen1.
In their study, Eiberg and his team recruited 800 blue-eyed men and women across different countries. They studied the genes that code for blue eyes in all of these individuals.
They were able to conclude that all blue-eyed folks have the exact same DNA sequence that accounts for their blue eyes. They also found that this DNA sequence contains an ancient genetic mutation that occurred presumably 10000 years ago around South-Eastern Europe. In other words, Matt Damon and Elijah Wood are your distant cousins, if you have blue eyes. In fact, everyone with blue eyes is related.
On the other hand, people with brown eyes have a significantly higher degree of inter-individual variation in their eye-color genes.
How did Brown Eye Mutate to Blue 10000 Years Ago?
Genetics is fascinating!
The mutation that gave rise to blue eyes altered the OCA2 gene, a gene that codes for the production of the brown pigment (melanin) in our eyes.
To keep things simple and preventing you from falling asleep, let’s assume the OCA2 gene is the recipe and melanin is one of the ingredients used to produce eye color. The mutation was like an error in the recipe which led to the amount of the ingredient, melanin, to be altered, resulting to very little melanin production in the iris of the eyes. The low melanin concentration is insufficient to produce the default color in brown eyes, but enough to express blue eyes2.
For 10000 years, the blue-eye gene has been passed on from parents to offspring and spreading to different geographical regions. A descendant expresses blue eyes if he or she inherited the right set of genes from both parents. It is believed that almost every blue-eyed person on earth today inherited the said mutation from the same source.
A tiny fraction of blue eyes are caused by health conditions such as waardenburg syndrome and ocular albinism; they are characterized by pigmentation problems. These medical conditions can affect as much as six different genes that are responsible for eye color. These health conditions impact the growth and development of pigment-producing cells, potentially leading to a much lower pigment concentration than in the case of the OCA2 mutation.
Apart from pigmentation defect, waardenburg syndrome is associated with congenital hearing loss and heterochomria. Ocular albinism just like other forms of albinism has been linked to severe ocular defects including high sensitivity to light and involuntary eye movements.
Why are There So Many Blue Eyes in Europe?
Almost everyone in Africa and Asia has brown eyes. This is also true for most of the rest of the world. In contrast, Europe has the widest variety of eye color. It also has the largest proportion of people with blue eyes. In fact, over 80% of the inhabitants of Estonia and Finland have blue eyes.

But why are there so many blue-eyed people in Europe? The first thing to consider is the epicenter of the blue-eye gene mutation, which was around the regions of Europe. This might be one of the most important factors to explain the high proportion of blue eyes in Europe.
Another important hypothesis is partner selection. The gist is that partner selection was much stronger in ancestral Europe than anywhere else in the world. In other words, a European guy in those days was more attracted to women with blue eyes than those with brown eyes. This type of selection might have increased the likelihood of giving birth to a child with blue eyes. This explains the big difference in eye color diversity in Europe versus the rest of the world3. Both hypotheses also explains why the proportion of black people with blue eyes may be the smallest.
