Do people with blue eyes have an advantage?
Advantages of Blue Eyes
A big advantage to blue eyes is that research shows they might be linked to a lower risk of developing cataracts. Cataracts are clouding of the eye's lens. According to some studies, blue eyes may have evolved because these individuals were able to cope better with seasonal affective disorders.
Grey eyed people scored the highest with the remaining colors close behind.
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.
Combined with the brown melanin, this results in the eyes appearing green. Blue eyes are potentially the most fascinating, as their colour is entirely structural. People with blue eyes have a completely colourless stroma with no pigment at all, and it also contains no excess collagen deposits.
Of all eye colors, brown seems to be the only one that could be called “advantageous” from a survival perspective. While more research is needed, darker irises are linked to a number of health benefits, including these: Reduced risk of macular degeneration. Lower melanoma risk.
In a website poll of over 66,000 respondents, 20% said green was the most attractive, followed by hazel and light blue at 16%. Brown was far and away voted the least attractive (6%).
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 eyes. This is the next most common eye color, encompassing about 10% of the population. While blue eyes are more sensitive to light during the day, people with blue eyes tend to see better at night – unless there are bright lights.
Blue Eyes. While most of us are actually born with blue eyes, they change within the first few weeks of life. Consequently, many people think that blue eyes resemble a youthful appearance. It is also said that people with blue eyes have a calm and peaceful personality, and are representative of wisdom and knowledge.
Therefore, they are sometimes attributed to “eternal youth.” Blue eyes are heralded by some to be the most desirable and attractive of eye colors, and those who have them possess a calm and peaceful personality. Blue eyes are also representative of knowledge.
What is the most intelligent color?
Psychology of Color: Black
It is also the color associated with intelligence (doctorate in black robe; black horn rimmed glasses, etc.)
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.
All people with blue eyes share a single common ancestor that lived between 6,000 and 10,000 years ago, according to researchers at the University of Copenhagen. Although blue is the second-most common eye color worldwide, it is still relatively uncommon, only seen in around 8 to 10% of people.
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.
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.
About half of Americans born at the turn of the 20th century had blue eyes, according to a 2002 Loyola University study in Chicago. By mid-century that number had dropped to a third. Today only about one 1 of every 6 Americans has blue eyes, said Mark Grant, the epidemiologist who conducted the study.
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.
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.
Blue eyes have been around for at least 7,000 years, but scientists still cannot agree on why they evolved. However, they have several interesting theories.
What is the most attractive eye color? Despite songs about blue eyes and brown-eyed girls, neither were found to be the most attractive eye color. Instead, gray eyes topped the chart with an average rating of 7.4, followed by blue and green eyes each scoring an average of 7.3.
What is the craziest natural eye color?
Pink and pale red eyes are also incredibly unusual eye colours and occur in people who have albinism. Albinism is when there is an absence of melanin which causes tiny red blood vessels to appear visible. Out of all the unusual eye colours, pink and red are the rarest in the world.
When it comes to color combinations, your eyes prefer black text on a white or slightly yellow background. Other dark-on-light combinations work fine for most people. Avoid low contrast text/background color schemes.
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.
Eye Color Matters
Lighter-colored eyes have less pigment to protect against sun damage and UV radiation compared to darker-colored eyes. This means that people with green, hazel, or blue eyes are more sensitive to light and more susceptible to UV damage.
For example, long-term sun exposure may cause your eyes to darken slightly, while a small percentage of Caucasian people's eyes lighten as they age. For the most part, though, your eye color will not actually change, and significant changes may be a sign of a larger problem.
