A black eye is also known as periorbital haematoma. A black eye develops when fluids collect in the tissues around the eye. The bruising and blue and purple discolouration are caused by broken blood vessels under the skin. These tissues will usually be swollen too.
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.
Black Eyes.
There's an eye disorder known as aniridia which makes the eye appear to have “no iris.” In truth, there is a small ring of iris tissue, but it is so small and the pupil is so large that it can look like the eyes are completely black. It is due to a chromosome mutation.
The rarest eye color in the world is likely violet or red—and yes, those colors can occur without the help of contacts. Many factors can influence eye color, including genetics and even certain medical conditions.
It shows up in about 9% of Americans but only 2% of the world's population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide. Black is not an eye color.
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 eyes
Brown is the least rare of eye colours and can range from dark chocolate hues to lighter chestnut shades. They can sometimes appear black as they tend to blend with the pupil of the eye; however, this is an illusion as black irises don't exist.
Black eyes: Responsible and passionate, people with deep, black eyes are considered extremely optimistic. They are always on their toes and keen to prove their worth to others. They are often secretive and do not like sharing much about themselves. Some have a strong spiritual bent.
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.
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.
“Can two parents with blue eyes have a child with brown eyes?” Yes, blue-eyed parents can definitely have a child with brown eyes.
Unfortunately, no. Just like your hair and skin color, the color of your iris is genetic. That means that unless you break down your genetic code or cell structure, your eye color cannot be changed permanently without surgery.
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.
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.
Eye color can change over time, but only slightly. The eye color of most babies will darken in the first few years of life. During this time, the body produces a darker pigment, known as melanin. Expansion or contraction of the iris can also lead to minute changes in eye color.
All human eyes are brown. As the owner of a sparkling set of deep brown eyes, I see no disappointment in the knowledge that all human eyes are in fact a wonderful shade of brown, but for anyone feeling misled or confused, a mix of biology and physics should help explain this reality.
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.
Genetics– The amount of melanin in the iris will decrease over time, just as hair color changes as we age, and can vary due to genetic determination.
Are Purple Eyes Rare? True purple eyes are exceedingly rare. Less than 1% of the world's population has them, making them rarer than blue, hazel, amber, grey, or green.
Most black eyes are superficial injuries that don't cause any permanent damage to the eye or to the tissues around it. When vision changes after a blow to the eye, it is a warning sign that the injury may be more than a simple bruise.
Generally speaking, yes, I find them attractive, but it highly depends how they look combined with the facial features of the said person and other factors. Brown/black eyes always have that sparkle that neither blue nor green eyes have and that can make them even more beautiful.
