In the United States, blue eyes are becoming less common. In the 1950s, more than half the population had blue eyes. Now, it is estimated that one in six babies has blue eyes.
Only 8 Percent of the World's Population Has Blue Eyes
Since blue eyes are genetically recessive, only 8 percent of the world's population has blue eyes. While blue eyes are significantly less common than brown eyes worldwide, they are frequently found from nationalities located near the Baltic Sea in northern Europe.
Of those four, green is the rarest. 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.
Their low melanin content is similar, but in fact, gray irises are significantly more rare than standard blue eyes. If you look closely, you might even spot streaks of brown, amber and gold within the gray. Even less common is a condition called heterochromia — different colored eyes.
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.
Can two parents with blue eyes have a child with brown eyes? Yes, blue-eyed parents can definitely have a child with brown eyes. Or green or hazel eyes for that matter. If you stayed awake during high school biology, you might find this answer surprising.
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.
Yes, natural purple eyes are possible. There are many different shades of blues and greys out there and many in-between colors. Although very rare, some people's natural pigmentation can even be violet or purple in color.
blue eyes descend from a single genetic mutation means that every single person on the planet with blue eyes descended from one common ancestor. In fact, a team of geneticists at the University of Copenhagen actually traced that mutation all the way back to a single Danish family.
Each parent will pass one copy of their eye color gene to their child. In this case, the mom will always pass B and the dad will always pass b. This means all of their kids will be Bb and have brown eyes. Each child will show the mom's dominant trait.
Red eyes.
Red is the rarest color, being characteristic of albinos. Here the iris contains no melanin at all, and light passes through it and reflects hemoglobin from the blood vessels on the retina, giving this hue.
Australian cricketer Shane Warne had complete heterochromia: his left eye was green and right eye was blue. Professional baseball pitcher Max Scherzer has complete heterochromia: his right eye is blue and his left eye is brown.
He says blue eyes have been linked to people coping better with seasonal affective disorder, a major depressive illness that occurs when there are long periods of low light. Notably, he says, the eye has special neurones in the retina that can detect blue light and use this to help regulate circadian rhythms.
The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive. Given this information, you can determine what eye colors are dominant in the parents.
Scientists believe that it is possible to trace all blue-eyed people back to a common ancestor, who likely had a genetic mutation that reduced the amount of melanin in the iris. Most people with blue eyes are of European descent.
This rare condition only affects about 3% to 7% of people. If you're born with it, your liver doesn't make enough of an enzyme it needs to process bilirubin. The result is higher levels of bilirubin in your blood and yellow eyes.
The pupil can change size with certain emotions, thus changing the iris color dispersion and the eye color. You've probably heard people say your eyes change color when you're angry, and that probably is true. Your eyes can also change color with age. They usually darken somewhat.
5–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.
?❤️ Lady Gaga's hazel eyes are so deep and beautiful ?? ———————————————————— #ladygaga…”
In reality, though, David Bowie had a condition known as anisocoria, which effectively meant that the pupils in his eyes were of different sizes – which made his irises appear to be of different colours, too.
Audrey Hepburn
Though officially recorded as brown, the real color of her eyes remains a mystery with co-actors and fans finding it green, gray, blue and even hazel.
Are All Babies Born With Blue Eyes? It's a common belief that all babies are born with blue eyes, but this is actually a myth. A baby's eye colour at birth depends on genetics. Brown is also common, for example, but a newborn baby's eyes can range in colour from slate grey to black.
In fact, the top layer of a blue iris doesn't contain any pigment at all. This lack of pigment is the reason that blue-eyed people may be more sensitive to bright light and have a greater need to wear sunglasses than their brown-eyed counterparts.
Iris color, just like hair and skin color, depends on a protein called melanin. We have specialized cells in our bodies called melanocytes whose job it is to go around secreting melanin. Over time, if melanocytes only secrete a little melanin, your baby will have blue eyes.
