The hard truth about eye color is that there really isn’t one eye color that is fully agreed upon as being the rarest in the world.
With that being said, there are a couple colors that are more uncommon than others among most parts of the world, which in turn makes them generally rarer than most other colors.
Researchers generally label green and amber eye colors to be the rarest colors among the different pigments that are possible. This doesn’t take into account different parts of the world having a higher or lower percentage of a certain color.
How Many People Have Green Eyes
While there are only a few key studies to support green eyes being the most rare, preliminary studies show that only 2 percent of the world’s population has true green eyes.
However, as previously mentioned, an eye color being “rare” is subjective to the region in which the study was conducted, or the region that was targeted.
As a recent article by Owlcation stated, “2% of the world’s 7.3 billion population is 146 million. This is roughly the population of Russia.”
That excerpt is not to say that having green eyes is any less special than it sounds, but rather to further express that the rarity of an eye color is dependent on how closely that 2 percent are to each other geographically.
Where Do Green Eyes Come From?
Green-eyed people most commonly originate from northern and central parts of Europe, as well as some parts of Western Asia.
For example, Ireland and Scotland both boast a whopping 86 percent of the population having blue or green eyes.
In Iceland you’ll find 89 percent of women and 87percent of men have either green or blue eyes. That is considerably more than the mere 15percent of the U.S. population that has blue or green eyes.
But of course, even though Europe has the highest percentages, anyone of any nationality can have green eyes.
How Rare Are Amber Eyes?
Amber eyes are at least, if not more, rare than green eyes.
While other color eyes such as hazel or brown can develop specks of amber, true amber eyes are seen as those that are completely solid with a yellow or golden hue.
Amber or golden eyes can often be found in animals, such as cats, owls, and especially wolves, but a human containing this pigment is extremely rare.
Only about 5 percent of the world’s population can say they have true amber-colored eyes.
How Can You Tell Amber Eyes Apart From Hazel Eyes?
Under dim light, it is difficult to differentiate amber eyes from hazel. The difference is subtle, but effective.
Amber eyes, unlike hazel, do not contain specks of red, while amber eyes are solid gold with no specks.
Amber eyes get their color from an increase of a chemical called lipochrome in the iris of the eye.
Because there are so many different individual scenarios when it comes to something as unique as the color of your eye, it is increasingly difficult to judge what color in considered the rarest.
While green and amber are widely considered the rarest two for argument’s sake, there are other variations that could be considered rarer in nature than either color.
Singularities like Heterochromia, where one eye is a different color than the other, are considerably rarer than green or amber eyes.
But even if there are many different instances for us to disagree about, one thing we can all agree on is that there are some truly beautiful colors in our eyes, and each is as unique as the next.
