Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes. Green eyes don't possess a lot of melanin, which creates a Rayleigh scattering effect: Light gets reflected and scattered by the eyes instead of absorbed by pigment.
Violet or Red Eyes: The Rarest Spectrum
This eye color is often associated with albinism, a genetic condition that results in the absence of melanin, the pigment responsible for coloring hair, skin, and eyes.
Brown, which is the most common eye color in the world. Green, which is the least common eye color.
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.
How Rare Are Purple Eyes? People with purple eyes make up less than 1% of the world's population. This means purple, or violet, is truly one of the rarest eye colors across the globe.
Violet Eyes
This color is most often found in people with albinism. It is said that you cannot truly have violet eyes without albinism. Mix a lack of pigment with the red from light reflecting off of blood vessels in the eyes, and you get this beautiful violet!
Changes in eye color are rare. Sometimes, the color of your eye may appear to change when your pupils dilate. The colors in your environment, including lighting and your clothes, can give the illusion of eye color change.
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.
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.
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.
Blue Eyes. Originally, all humans had brown eyes. Some 6,000 to 10,000 years ago, a genetic mutation affecting one gene turned off the ability to produce enough melanin to color eyes brown causing blue eyes.
A technique to change the eye color in a safe and effective way by applying laser to the iris, without surgery. The laser diminishes the density of the iris pigment, lightening the eye color.
Unusual eye colors
True pink, red, or violet eyes are due to albinism, a condition in which the body is unable to produce or distribute melanin. The pink color is the color of the retina showing through.
Brown Eyes: 45 percent. Blue Eyes: 27 percent. Hazel Eyes: 18 percent (Note: Hazel eyes consist of shades of brown and green.) Green Eyes: 9 percent.
Each person inherits 23 chromosomes from each parent, which makes up 46 chromosomes in total. These pieces of DNA determine eye color. You receive DNA from both parents, and the combination of those DNA strands in the chromosomes will determine your eye color.
Amber eyes are extremely rare. Most sources say that only about 5% of people have true amber eyes. Coming up with a hard and fast number or percentage, though, is not as easy as you might think—there simply haven't been enough large-scale studies done to quantify eye color prevalence with certainty.
Green Eyes
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes.
African-Americans with blue eyes are not unheard of, but they are pretty rare. There are lots of ways for this to happen. Some possible ways an African-American person might have ended up with blue eyes are: Caucasian relatives in their ancestry (the most likely reason)
In most people, the answer is no. Eye color fully matures in infancy and remains the same for life. But in a small percentage of adults, eye color can naturally become either noticeably darker or lighter with age. What determines eye color is the pigment melanin.
The cool thing is that when the pupil changes size, the pigments in the iris compress or spread apart. This changes the eye color to a degree. The pupil can change size with certain emotions, thus changing the iris color dispersion and the eye color.
A blue sclera can be a sign of many conditions. In young children, the cause may be an inherited genetic condition, most often a condition that affects the connective tissue in your body. In adults, iron deficiency may cause your sclera to look blue. You generally won't have pain or other symptoms with a blue sclera.
Eye redness is most often due to swollen or dilated blood vessels. This makes the surface of the eye look red or bloodshot. The white portion of the eye (sclera) can appear red when the vessels on the surface become enlarged.
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.
Brown eyes are the most common: Over half the people in the world have them, according to the AAO. In fact, about 10,000 years ago, all humans had brown eyes.
