Heterochromia is fairly uncommon, occurring in less than 1 percent of the population. It can be caused by several factors and present itself in different ways. What causes Heterochromia? The color of our eyes comes from the appearance of the pigment that is present in the iris, the central part of the eye.
At some point, you've probably wondered what the rarest eye color is. The answer is green, according to the American Academy of Ophthalmology (AAO). Only about 2 percent of the world's population sport this shade.
Though common in some breeds of cats, dogs, cattle and horses due to inbreeding, heterochromia is uncommon in humans, affecting fewer than 200,000 people in the United States, and is not associated with lack of genetic diversity. The affected eye may be hyperpigmented (hyperchromic) or hypopigmented (hypochromic).
Different colored eyes are most commonly found in certain breeds of domesticated animals like cats and dogs.
Physical beauty - of which eye color is only a small part - is just one of those components. Yes, a person with heterochromia iridis can be attractive.
Complete heterochromia is definitely rare — fewer than 200,000 Americans have the condition, according to the National Institutes of Health. That's only about six out of every 10,000 people. It's currently unknown how rare central heterochromia is, but we do know that it isn't quite as rare as complete heterochromia.

There are several ways people can have two different colored eyes. People can be born with heterochromia, or it can result from disease or injury. It's pretty rare for people to inherit mismatched eyes from their parents.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
Finally, a marked sexual dimorphism was observed, as in females heterochromia is much more frequent than in males.
Most of the time, it doesn't cause any problems. It's often just a quirk caused by genes passed down from your parents or by something that happened when your eyes were forming. In rare cases, it can be a symptom of a medical condition. Heterochromia is common in some animals but rare in humans.
For the most part, your eye color will stay the same from infancy. Research has found that eye color can change in rare cases due to injury or genetics.
Most cases of heterochromia are hereditary, caused by a disease or syndrome, or due to an injury. Sometimes, one eye may change color following certain diseases or injuries. Specific causes of eye color changes include: Bleeding (hemorrhage)
Most of the time, heterochromia doesn't cause any problems to your eye health and it does not affect your vision either. It's often just another characteristic passed down to your genes through your parents. However, it can also be triggered by a medical condition or trauma to the eye.
There are generally no risk factors associated with heterochromia, and it is also not an inherited disease. However, it is possible to have heterochromia because of inherited diseases like Waardenburg syndrome and piebaldism.
Likewise, two brown-eyed parents can have a child with blue eyes, although this is also uncommon.
A recent survey conducted by CyberPulse, a division of Impulse Research Corporation in Los Angeles uncovered this colorful research. Intelligence was the number one trait associated with brown, the most common eye color in the U.S., by 34 percent of respondents.
Blue eyes are crowned the sexiest among men and women
According to our research, blue is the sexiest eye colour, as the majority of the world's sexiest people, both male and female, have blue eyes.
Violet and red are unique eye colors caused by an iris with little to no pigment. When light reflects off of the blood vessels in eyes that lack typical pigmentation, the eyes appear violet or red. Astonishing as it may seem, these eye colors occur naturally—and are extremely rare.
But again, just like mosaics, you would not pass your sectoral heterochromia to your child. Your child would get either a brown or a green eye color gene, not a combination of the two.
Heterochromia is a unique phenomenon where one eye (or a segment of the eye) is a different color from the other eye. This extraordinary event doesn't often happen in the general population. While it is possible in twins, it is very rare, and we don't see it as a regular occurrence by any stretch.
Perhaps the most famous celebrity with heterochromia, actress Kate Bosworth, has one blue eye, and one eye that is partially hazel.
Yes, although rare, light hair, eyes and skin are found throughout West Asia, Central Asia and East Asia.
Injury. In some cases, an injury to the eye may cause one of the eyes to change color. This is also possible with the trauma that can occur when someone has certain types of eye surgeries. Bleeding in the eye, due to a condition or an injury, may also influence a change in the color of the iris.
