Blue-Green Eyes: Learn About This Rare Color | male advice (2023)

Blue-green eyes are uncommon

blue green Eyesthey are amazing to look at. Part of the reason they catch our attention is that they are extremely rare. Although the science is somewhat scattered, the current isInvestigationsuggests that only about 3-5% of the human population has true blue-green eyes.

This is amazing considering there are over 7 billion people on the planet. Also, it is unusual to have blue-green eyes as the human species has only three predominant shades:

• azul
• Green
• Braun

Blue-green eyes also capture our imagination as both colors are rare. As you will read later, most people on the planet have brown eyes.

Eye colors: the top 3

Before we learn more about the rarity of blue-green eyes, it might be helpful to take a closer look at the three primary colors mentioned above: blue, green, and brown.

Blue eyes

Blue eye research is a hot area of ​​science. We believe that around 8% of the world's population currently has blue eyes. It's important to say that we still don't know for sure.

If this number is correct, it means that almost 56 million people are born with a shade of blue.

People from northern Europe, especially Scandinavia, seem to have the most blue-eyed people.

Note that there are different shades of blue, including aquamarine, crystal, and "sky blue". And there can be a mixture of different cuts that result in hazelnut.

where do blue eyes come from

There are several theories about the origin of blue eyes. Since we're seeing certain ethnic groups with more blue-eyed people, it's believed that a genetic factor is at play.

For example, people born in Germany, Ireland, Scotland, England and Northern Italy appear to have a higher proportion of blue eyes compared to other countries.

In fact, regional studies suggest that about 70% of the people native to these areas have some shade of blue-green. Some people refer to them as seaweed paints.

There was a time when it was thought that if a person was born with blue eyes, it meant their father had a dominant gene. In fact, this theory was so reliable that it was taught in most schools and colleges.

Think about your biology classes. Remember?

However, in 2008 an article appeared in theAmerican Journal of Human Geneticsit took away a lot of what we thought we knew about eye color.

Current thinking now suggests that there are 16 genes that affect eye color and having a family member with a dominant gene may not be that important.

Origin of the blue eyes

The debate about the origins of blue eyes continues. Recent research points to the possibility that blue-eyed people share a common ancestor; postulated by the University of Copenhagen.

Through a series of genetic mutations over millions of years of adaptation, blue eyes became part of the human race.

We still don't know if the blue color in eye color has a specific function.

Green eyes

If you have green eyes, consider yourself in a very special club. Because current research suggests that only 2% of the world's population has green eyes.

We see people with green eyes all over the world. The highest concentration of this color (including brown eyes) is found in most parts of Europe. Interestingly, we also see shades of green in western Asia.

If you do the math and break down the 2% above, that means only about 140 million out of 7 billion people on the planet are shades of green.

Where do green eyes come from?

Like blue eyes, green eyes are believed to be part of the human species due to genetic adaptations. Humanity as we know it has only existed on the planet for 200,000 years.

But if you trace human ancestry on a geologic timescale and factor in adjustment factors, we can pinpoint our beginnings to almost two million years ago, during whichPleistocene epoch.

At some point during the evolutionary period, green eyes appeared as part of humanity. Some scientists believe a functional aspect was involved, possibly due to extinction events. We still don't know the real answers.

What is clear is that green eyes are rarer than blue eyes and that we see different shades of blue-green in many people. This color is most common in Caucasians. Why this is so remains a mystery.

Brown eyes

Brown eyes are the most striking color on the planet. As with the other cuts mentioned, we're not sure how many people have brown eyes. Current research suggests that around 65% of the world's population has some form of brown pigmentation in the iris.

We see brown-eyed men and women all over the world. The greatest concentration of people with brown eyes, including hazel eyes, is found in southern Europe, Africa and throughout Asia.

South Americans tend to have darker eyes. The shifting of the tectonic plates could be the causative reason that Pangea broke apart and formed Africa and South America. Watch this short video below to learn more.

What is the origin of brown eyes?

Like the eye colors mentioned above, brown eyes are said to have existed on Earth since the earliest manifestations of mankind. Some scientists believe that most early humans were some kind of brown color; but they are not sure why.

What's interesting is that if you look at eye color, most monkeys are generally brown, with some having a hazel tooth.

Brown is believed to have been a camouflage color as part of human adaptation, allowing early humans to hide in the undergrowth during the hunter-gatherer phase of evolution.

blue green eyes

All of the above material brought us to the topic of blue-green eyes. what exactly are they And why do some people have one blue and one green eye?

Blue-green eyes are no different from the other eye colors above in terms of origin. They are believed to be part of human evolution as part of adaptation.

What is different about blue-green eyes is the nickname they often use; hazel eyes. But what a lot of people don't realize is that you don't have to have a combination ofblue and greenhas "hazelnut". That's because hazel eyes can be blue-brown or greenish brown.

Origin of the blue-green eyes

Perhaps the most intriguing part about blue-green eyes has to do with their origins. Research suggests that the mixed shade of blue-green first appeared in humans around 10,000 years ago.

If you look at the geologic timescale mentioned above, it wasn't that long ago!

Several scientists believe the blue-greens' adaptation occurred sometime after the last ice age, around 8,000 years ago.

Here's a direct quote from the research that appears inHuman genetics2008 on this topic:

"A single haplotype, represented by six polymorphic SNPs covering the last 3' half of the HERC2 gene, was found in 155 blue-eyed individuals from Denmark and 5 and 2 blue-eyed individuals from Turkey and Jordan, respectively."

If you get past the scientific jargon, scientists are basically saying that blue and green may have originated in Scandinavia, but eventually interbred with humans mating in modern Mesopotamia.

rare blue-green eyes

True blue-green eyes are extremely rare. To qualify as blue-green, one must have a touch of both colors in the iris. This is a characteristic feature that distinguishes people with brown eyes, where green or brown is striking.

A person can also have blue-green eyes if each eye is a different color. For example, actor Josh Henderson has one blue eye and one green eye. Very very rare.

Why do some people have one blue and one green eye?

Scientists believe that some people are born with different eye colors (also known as mixed eye colors) due to a genetic accident. The name of this condition isHeterochromie.

To be honest, we don't know the answer. The DNA of both parents is part of the child's genetic material, which may have been altered during the developmental phase of the zygote.

There are no in utero studies currently explaining what is going on.

THE SCIENCE OF BLUE EYES

The science behind blue-green eyes

If a person is born with blue-green eyes, it is a direct result of genetics. As mentioned above, 16 known genes are involved in this process.

melanin and eye color

There is a substance called melanin that is common to all humans. Composed of a complex polymer containing the amino acid tyrosine, this chemical has a lot to do with how others see your eyes.

Melanin-based reaction

The concentration of melanin in your eyes reflects light from its source. The richer the melanin, the deeper the color a person sees.

However, if you have blue-green eyes, it's possible what's reflected in the back is black. This is because the base of the iris cannot project these two discs at the same time.

light green and blue eyes

Part of your eye contains something calledIris. This iris itself consists of two layers, one at the front and one at the back.

Stuck between the two is theStoma, which consists primarily of collagen. This information is important to know because eye color, such as blue-green, is not determined by the iris itself.

Rather, the hue is related to how the aforementioned melanin reflects the background light.

Light reflection can be natural or artificial. In any case, the light itself has a major impact on how others perceive your eye color.

eye color chart

When you look closely at someone with blue-green eyes, doesn't it seem like their color is changing right in front of you? This is due to the way light reflects off the melanin base.

Or to put it scientifically:Rayleigh scattering.

While this might sound like a fancy term, Rayleigh scattering is a phenomenon that determines how light is diffracted and scattered. That's why you experience a blue sky instead of a red one like on Mars.

Here's a video that might help explain better how this dynamic works.

Blue and green eye changes

There are other factors that affect how others perceive blue-green eyes. Examples include:

• to cheer
• Clothing
• Invent
• Climate
• medical reasons

What has been said above may sound strange, but remember that eye color is almost always perceived by the presence of light. The intensity of this color also depends on the chemical reactions taking place in the body.

When you are in a bad mood, your eyes become waterier and therefore lighter. If someone with blue-green eyes wears a light-colored shirt, their eye color will appear darker.

The same goes for the weather; that is, the amount of sun in the sky. In general, the more sunlight falls, the clearer the eye color is expressed.

Can you change the color of your eyes?

There are artificial means that people use to change their eye color. This is done primarily through the use of contacts. But if you have very dark eyes, like Hazel, wearing contact lenses can make you look fake.

Myths about blue and green eyes

There are several myths associated with blue-green eyes. Here is just a small example:

• People with blue-green eyes are smarter
• People with blue-green eyes are more attractive.
• Blue-eyed people can hypnotize people.
• Blue-eyed people live shorter lives
• Blue-eyed people are part Latina
• Men with blue-green eyes are mostly Scorpios.
• Blue-eyed women are mostly Pisces

Do blue-green eyes come from aliens?

Some people think that a blue-green eye color combination is the direct result of extraterrestrial interference with planet Earth.

Obviously there is no evidence to support this claim, but that doesn't stop some people from believing it. FYI: Some people think owls are from aliens too.

The reason why the rumor originated comes mainly from urban myth. Since blue-green eyes are very uncommon, some people have looked for a supernatural explanation. Stupid, but that's how the gossip started.

final thoughts

Eye color is determined by many factors, including genetics, melanin pigmentation, and light phenomena.

With each passing year, scientists are learning more and more about the origins of eye color, including blue-green eyes.
