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.
Violet or red eyes are among the rarest eye colors, with less than 0.01% of the population having this unique hue. 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.
A vast majority of airlines around the globe operate redeye flights, as it allows for efficient aircraft utilization. After all, airlines don't make money when planes are parked on the ground. Here in the United States, the only major airline to not operate redeyes is Southwest.
Eyes that appear red or violet under certain conditions due to albinism are less than 1 percent of the world's population.
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.
The second-rarest eye color is hazel, a mixture of brown and green with golden flecks. About 18% of Americans have hazel eyes, compared with about 5% of the world's population.
These include: Albinism: People who have an inherited condition called albinism have little or no melanin in their eyes, hair and skin. People with albinism usually have eyes that are very light blue. Rarely, they have pink or red eyes.
We could for instance, develop red eyes as our DNA mutates, and have darker skin as an evolutionary response to global warming.
In many cases, red eyes aren't dangerous and may not even need treatment. However, there are conditions that cause red eyes that can be more serious. If your eye redness lasts longer than a day or two, or if your young child has red eyes, you should contact your healthcare provider.
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.
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. But the fact is that a small (albeit very small) percentage of people are indeed born with purple eyes.
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.
Legendary actress Elizabeth Taylor's eyes were famous for being stunningly beautiful and distinct. Widely known for having the most striking eyes in Hollywood, Taylor had what appeared to be rare natural purple 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.
“Can two parents with blue eyes have a child with brown eyes?” Yes, blue-eyed parents can definitely have a child with brown eyes.
Around 90 million years ago, our primitive mammalian ancestors were nocturnal and had UV-sensitive and red-sensitive color, giving them a bi-chromatic view of the world.
The results from genetic crosses and genetic inheritance from the present and previous studies [2] [3] revealed that the red eye color is inherited as a simple Mendelian autosomal recessive gene. The location of the red gene on BPH chromosome 9 confirms that the red eye mutation is located on an autosome.
Biochemical analysis and electronic microscopy examination revealed that the red-eye mutants contained decreased levels of both xanthommatin (brown) and pteridine (red) and reduced number of pigment granules. Thus, the changes of amount and ratio of the two pigments is the biochemical basis of this red-eye mutation.
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. In fact, brown eyes are even the most common eye color in newborn babies.
Pink eye is an inflammation of the transparent membrane that lines the eyelid and eyeball. This membrane is called the conjunctiva. When small blood vessels in the conjunctiva become swollen and irritated, they're more visible. This is what causes the whites of the eyes to appear reddish or pink.
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.
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.
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. What is this? People with albinism usually have very pale or colorless skin, hair, and eyes.
