Perhaps the rarest eye color is not one color at all, but multicolored eyes. This condition is called heterochromia iridis. A person can be born with this condition, it can develop in infancy, or it can develop as a symptom of a systemic disease or after an injury to the eye.
A condition called heterochromia causes the iris to be different colors. People with this condition may have different colors within one eye (for example, the iris may be half one color and half another). Or they may have a different color in each eye. Most often, heterochromia results from a harmless gene change.
Encountering someone with two different colored eyes is rare. In fact, only about 6 in every 10,000 people in the United States have different colored irises, a phenomenon known as heterochromia.
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.
The first-ever pair of baby blues was a genetic fluke that was passed on—and on and on. The second-rarest eye color is hazel, a mixture of brown and green with golden flecks.
Unbelievable as it may seem, the answer is yes—natural purple eyes do exist. Purple eyes are also commonly referred to as “violet eyes,” as they are typically a light shade. For most people, this striking eye color can only be achieved with the help of colored contacts.
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.
Permanent changes to eye color can be achieved through iris implant surgery, corneal pigmentation, and laser eye color change. Iris Implant Surgery is a procedure that inserts a prosthetic iris into the eye. It was originally developed to treat iris defects such as albinism and aniridia.
Did Elizabeth Taylor have violet eyes? These days, thanks to colored contact lenses, anyone can have violet-colored eyes . Taylor didn't come by her purple peepers that way; the first tinted contact lenses weren't commercially available until 1983. Taylor's eye color was the real deal.
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.
When broken down by gender, men ranked gray, blue, and green eyes as the most attractive, while women said they were most attracted to green, hazel, and gray eyes. Despite brown eyes ranking at the bottom of our perceived attraction scale, approximately 79% of the world's population sports melanin-rich brown eyes.
“Can two parents with blue eyes have a child with brown eyes?” Yes, blue-eyed parents can definitely have a child with brown eyes.
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.
Red/Pink Eyes
Two major conditions cause a red or pinkish eye color: albinism and blood leaking into the iris. Although albinos tend to have very, very light blue eyes due to a lack of pigment, some forms of albinism can cause eyes to appear red or pink. Amber eyes are a beautiful honey color!
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.
How common is pink eye? Pink eye is one of the most common eye infections in children and adults. There are about 6 million cases of pink eye in the U.S. each year.
Around 17 per cent of people have blue eyes, and when combined with 1-2 per cent having red hair, the odds of having both traits are around 0.17 per cent. That's 13 million people, out of the 7.6 billion on Earth.
Colors can range from a lighter chestnut to darker hues that almost seem to blend in with the pupil. While some people may appear to have irises that are black, they don't technically exist. People with black-colored eyes instead have very dark brown eyes that are almost indistinguishable from the pupil.
Only 1% of people have pink and pale red eyes; they are typically albinos. Albinism happens when there is a problem with one of the genes inherited from the mother. Like red eyes, heterochromia is rare and effects less than 1% of the population.
Close to 3% of the world's population have gray eyes. People with gray eyes have little or no melanin in their irises, but they have more collagen in a part of the eye called the stroma. The light scatters off the collagen in a way that makes the eyes appear gray.
The rarest skin color in the world is believed to be the white from albinism, a genetic mutation that causes a lack of melanin production in the human body. Albinism affects 1 in every 3,000 to 20,000 people. People with albinism usually have very pale or colorless skin, hair, and eyes.
Eye Color Changes Not Related to the Iris
Arcus senilis is a hazy blue or white ring on the cornea from a build-up of a natural fatty substance called lipids. It's common with aging and usually harmless. Most seniors have some degree of arcus senilis.
