How Rare Are Hazel | Blue And Green Eyes

Hazel eyes are rare, as they account for only 1% of the US population. Blue eyes are also scarce, although they make up close to 8% of the US population, making them more common than brown eyes.

Green eyes are even rarer than blue eyes, with only about 0.5% of the population having this eye color. In total, it’s estimated that only about 3% of the US population has one of these unique eye colors.

How standard are different eye colors?

White Europeans have brown eyes, while Asians and Native Americans have black eyes.

But how common are different eye colors; For instance, how many people in America have brown or green eyes; And what about that mysterious eye color known as hazel; To get a good sense of how standard specific eye colors are in America today, we first need to define terms. What do we mean by brown, green, or hazel; Are all of these precisely interchangeable terms for one group of people; In short: No. But here’s why.

There is no scientific definition for brown vs. green vs. hazel. The closest thing comes from an organization that aims to raise awareness about color blindness.

They say you can consider someone with a dark-colored iris as having brown eyes. So technically, if you had dark-colored eyes, you could be viewed as either Brown or Green depending on which system you want to use (though they’re not very accurate distinctions).

However, it also says that people with lighter-colored irises have green eyes, and those with medium-shaded irises have brown eyes. So it might be easier to think of them separately when discussing statistics like these.

What is eye color genetics?

There are three central eye color genes: EYCE2/OCA2, SLC24A4, and HERC2. The most common form of eye color is brown (OCA2), caused by a variation in the OCA2 gene

About 88% of Caucasians have brown eyes due to OCA2. Blue eyes occur when there is only one functional copy of a gene called HERC2 on chromosome 15. When both copies (one from each parent) aren’t working correctly or aren’t present, it results in a complete loss of eye color.

This can be caused by inheritance or new mutations that affect one or both copies of your HERC2 gene. If you inherit a mutated copy of HERC2 from just one parent, you may still have some pigment in your iris but not enough to give you blue eyes.

Green eyes come about when someone has two mutated copies of HERC2. If you inherit two imperfect copies, you won’t produce any pigment resulting in green eyes.

Hazel Eyes: Hazel-colored eyes are created by having both brown and green pigments in your iris as well as flecks of gold, orange, red, or even purple!

These colors blend to create an overall brown appearance. Hazel-colored eyes are typically considered a medium shade between light brown and light green with flecks of darker colors throughout them.

What causes red eyes?

There are many reasons why you might have red eyes, both healthy and unhealthy. A few of these common causes of red eyes include allergies/hay fever; Allergic conjunctivitis; Blepharitis (infection around eyelids); Bloodshot eye syndrome; Dry eye syndrome; Pink eye (conjunctivitis); Pterygium (skin growth on the white part of your eye); Sunburned or irritated eyes.

Suppose you suspect your eyes are red due to an underlying condition. In that case, it’s essential to see a doctor as soon as possible.

How do I find out if I’m color blind?

The best way to find out if you’re color blind is to have your vision tested by an eye doctor. A simple eye exam can provide information about your ability to see colors.

That’s because some color blindness genes cause achromatopsia, a total color deficiency that prevents you from seeing any colors.

Most people who have problems distinguishing specific colors like blues or reds have partial color blindness. In these cases, doctors use unique charts to test for particular vision problems related to each type of color blindness.

They’ll also test for other conditions that can cause similar symptoms, like diabetes or thyroid disease. If you think you might be color blind, talk to your eye doctor about getting tested. 

How rare is it to have two different colored eyes?

It’s relatively common. Between two and five percent of people have different colored eyes; some experts claim it’s as high as 10 percent. The vast majority of these cases, at least 80 percent, are genetic.

The rest arise from accidents or illness (think: traumatic brain injury). Hazel eyes occur when a light pigment called melanin mixes with a darker variety called eumelanin, resulting in a brownish shade with green or gold flecks.

Blues and greens occur when pheomelanin mixes with melanin, producing shades like turquoise or teal though blues tend to be deeper than greens.

And while you can have any combination of eye colors, chances are your other eye will match your dominant one. So if you’re right-handed and right-eyed, the odds are good that your left eye is also right-dominant.

And vice versa for lefties. But sometimes, things don’t work out so neatly. If one eye is more dominant than another, they may not match at all even if you’re 100 percent ambidextrous!

Or perhaps you were born with heterochromia iridum. This inherited condition causes one iris to be a completely different color than its partner.

Though there’s no official list of symptoms, heterochromia iridum can cause total color blindness in one eye or even partial vision loss in both eyes. In addition to being rare, having two different colored eyes is often considered attractive and has been throughout history. 

Conclusion

Eyes come in every color imaginable. However, there are five primary eye colors: brown, black, blue, green, and gray. Hazel’s eyes appear when both brown and green irises mix. Blue eyes have only a tiny amount of pigment; people with actual blue eyes can often see some of their colored iris or pupil through their clear sclera or white part of their eye.

Green eyes contain more pigmentation than any other iris color because they’re partially made of dots of gold-colored melanin. Generally, it’s tough to determine how standard specific eye colors are. The combination of genetic factors that result in an individual having one eye color over another makes finding exact percentages challenging to pinpoint.
