"Hazel" eye coloring is sometimes caused by central heterochromia. It's still not particularly prevalent in general, but it's not as rare as one might think.

Can central heterochromia eventually expand to sectoral or complete heterochromia?
my good sir, i am asking the exact same question...
Does Central heterochromia affect eye sight?
Nope
How much of the world's population has heterochromia?
Actually, a decently sized amount of people have Central Heterochromia and neither is it very rare to have Sectoral Heterochromia. As for the numbers, I don't know the exact percent.
How rare is sectoral heterochromia?
I would have to completely disagree as well. Central Heterochromia is so common it's not even funny. I have Sectoral (or partial) heterochromia and i have yet to see anyones eyes (in person) that look like mine. I have one full blue eye, and the other eye is brown with a chunk of blue in it.) So to answer your question- Central Heterochromia= definitely common. Have you seen many people walking around with two completely different colored eyes? I have to see even one, but think this - central heterochromia is even rare among that! It signifies abnormally levels of toxin in the body in most cases, but sometimes it's genetic. (I have central heterochromia) I have central heterochromi(genetic)I have three colors actuall. brown in the cener and green outter. but there is also a even darker green ring on the very outside edge of my iris. my dad has full heterochromia one eye is green and one is brown. His green eye also has central heterochromia. newtest3 ---- Hello! I would have to disagree with them. Central Heterochromia doesn't seem to be as rare as Partial or Full Heterochromia. I myself have Central Heterochromia and know a few other people who do as well, whereas I don't know anyone with Partial or Full. And from what I understand of the research I've done, Partial is even rarer than Full. In the people I know with Central Heterochromia, most of them are usually classified as having "hazel" eyes because they have those different colored rings. Now, that's not the case for all people with hazel eyes, but it's very common for them to be misclassified. So in terms of rarity, you have to think how many people in the world have hazel eyes? ~ I guess I'm the odd one then... I have Sectoral and Central heterochromia... My eyes are normally green, but when you look at the, the top half of both of them is brown. They also have a dark grey ring around the outside of them, as I just recently discovered. The odd thing about that, is that my mom had blue/grey-ish eyes, and my dad has hazel ones. Neither my parents, nor their parents have brown eyes.
Can Heterochromia be passed on to children?
Heterochromia is a genetic mutation that cannot be passed down to children. It occurs as a defect in meiosis, and it produces an extra gene for eye colour. Alas, there is a greater chance that the child of a person with heterochromia will also get heterochromia, because there is a better chance of the gene mutating. But still, the chance of heterochromia is rare nonetheless.
How many people have heterochromia?
Complete Heterochromia is rare in humans, but it is common in animals such as dogs and cats.
Is sectoral heterochromia inherited?
sectoral heterochromia is an autosomally dominant trait, meaning it is inherited from both your parents.
Is heterochromia bad or good?
it depends on your point of view. Heterochromia is just a variation in eye color; not harmful.
What color are Logan Lerman's eyes?
According to his official website, Logan Lerman has blue eyes. However, Lerman is listed to have heterochromia iridum, meaning that there is a difference in coloration of the iris of the eye, although his heterochromia is only central or partial heterochromia, meaning that the color only varies toward the center of his eyes. So, Logan Lerman's eyes are blue but they change a different color toward the center of his irises.
What color eyes des Beyonce Knowles have?
They're hazel, they're a dark green/amber with a significant amount of brown around the pupil (central heterochromia).
As you move towards the pupil my eyes have a deep teal outline then are blue then they are green then a yellowish gold and then pale grey and they change does this mean i have heterochromia?
your eyes sound exactly the same as mine. i believe it's called central heterochromia (ie. the centre of your iris is a different colour). It's very common.
What percentage of dogs have heterochromia?
3.5%
