What is the truth about blue eyes?

People with blue eyes have a completely colourless stroma with no pigment at all, and it also contains no excess collagen deposits. This means that all the light that enters it is scattered back into the atmosphere and as a result of the Tyndall effect, creates a blue hue.


What is so special about blue eyes?

Blue Eyes are More Sensitive to Light

Melanin in the iris of the eye appears to help protect the back of the eye from damage caused by UV radiation and high-energy visible “blue” light from sunlight and artificial sources of these rays.

What race did blue eyes come from?

Scientists concluded that every blue-eyed person on the world today can trace their ancestry back to a single European who probably lived about 10,000 years ago in the Black Sea region and who first developed a specific mutation that accounts for the now widespread iris coloration.


What's the rarest eye color?

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.

Who is the first blue eyed person?

In 2006, researchers discovered a 7,000 year old body from the Stone Age in the La Brana cave system in Leon in Northern Spain (Image 4). Genetic testing determined that this man had blue eyes. It was not in itself unusual, but what is remarkable is that he is the earliest known person with blue eyes.


The Truth About Blue Eyes



Are blue eyes more intelligent?

Interestingly, in contrast to brown eyes, blue eyes were not associated with intelligence as only 7 percent of respondents thought of blue-eyed people as intelligent. Twenty-nine percent of participants associated green eyes with sexiness, the top characteristic thought to be related to this color.

Are blue eyes healthy?

Having blue eyes has its advantages. They lower your risk of developing cataracts, for instance. However, they might increase your risk of health problems like type 1 diabetes and eye cancer. Protecting your eyes and getting regular check ups is important no matter the color of your irises.

What is the prettiest eye color?

What eye color has the best vision?

Those with darker colored eyes experience less visual discomfort in bright, sunny conditions. Also, darker irises reflect less light within the eye, reducing susceptibility to glare and improving contrast discernment—so people with darker eyes may have better vision in high-glare situations, such as driving at night.

Do blue eyes have more issues?

People who are born blue-eyed are at higher risk of developing age-related macular degeneration. The research shows that there is less pigment in blue eyes, and green eyes for that matter, than there is in brown eyes. This means more light is able to penetrate blue eyes. This makes lighter eyes more sensitive to light.

Who can inherit blue eyes?

The laws of genetics state that eye color is inherited as follows:
  • If both parents have blue eyes, the children will have blue eyes.
  • The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.


Do blue eyes have the best vision?

While lighter-colored eyes may be more sensitive to sunlight, they are not necessarily more sensitive to vision. In fact, blue eyes have better visual acuity than brown eyes. This means that blue-eyed people can see small details more clearly.

Are blue eyes the stronger gene?

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.

Which parent determines eye color?

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.


Are blue eyes getting rarer?

The color blue is considered a genetic alteration, which may have occurred about 6,000 to 10,000 years ago. Before that point, it was believed that most people had brown eyes. In the United States, blue eyes are becoming less common.

What is your personality if you have blue eyes?

Charming, friendly, and attractive are just a few words to describe the blue eyed bunch. They are the type to help others and lend a helping hand. The great sense of observation and outgoing personality are just two added traits that come with having blue eyes.

Are blue eyes hotter?

According to our research, blue is the sexiest eye colour, as the majority of the world's sexiest people, both male and female, have blue eyes.

Can 2 brown-eyed parents have a blue-eyed child?

Yes. The short answer is that brown-eyed parents can have kids with brown, blue or virtually any other color eyes. Eye color is very complicated and involves many genes.

Is it true that all babies are born with blue eyes?

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.


Are all people with blue eyes related?

Blue-eyed? Thank a genetic switch that turns off your body's ability to make brown pigment in your peepers. Researchers have finally located the mutation that causes blue eyes, and the findings suggest that all blue-eyed humans share a single common ancestor born 6000 to 10,000 years ago.

Why are blue eyes less trustworthy?

Brown-eyed males tend to have a face shape that suggests happiness and, hence, higher perceived trustworthiness while blue-eyed males tend to have a face shape that indicates anger and, hence, lower perceived trustworthiness [5], [18], [19].

What are the disadvantages of having blue eyes?

Because blue eyes contain less melanin than most other eye colors, they may be more at risk of certain damage. Research has shown that lighter iris colors are associated with: A higher risk of ocular uveal melanoma (a type of eye cancer) A lower risk of developing cataracts.
