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.
A recent survey conducted by CyberPulse, a division of Impulse Research Corporation in Los Angeles uncovered this colorful research. Intelligence was the number one trait associated with brown, the most common eye color in the U.S., by 34 percent of respondents.
Whether you have light or dark colored eyes, your eye color does actually have an impact on your vision. If you have a lighter eye color, your eyes are more sensitive to light because you have less pigment and melanin in your irises to protect your eyes from the sun.
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.
So, this is what makes people with blue eyes more likely to have age-related macular degeneration. Macular degeneration is caused when the light-sensitive cells in the eyes start to die, which can eventually result in blindness.
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.
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.
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.
Light-eyed people (with blue or green eyes) have slightly better night vision because they have less pigment in the iris, which which leaves the iris more translucent and lets more light into the eye.
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.
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.
They Are Less Prone to Certain Eye Diseases
The sun can cause severe eye damage and result in eye diseases like cataracts and macular degeneration. But because brown eyes have more melanin, it's safe to say that if you have brown eyes, you are less likely to get these types of eye diseases.
Some people think you can determine personality by eye color. Brown is said to be more trustworthy, blue is sentimental, green is mysterious, hazel is determined, grey is more reserved, and black is impulsive.
In most people, the answer is no. Eye color fully matures in infancy and remains the same for life.
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.
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.
If you have green eyes, you're in luck. In addition to being the rarest eye color among Americans, green eyes are the most attractive, according to 66,000 people who voted in our survey.
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.
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.
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.
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
"In Australians of European ancestry, the percentage of eye colours are 45 percent blue-grey, 30 percent green-hazel and 25 percent brown. If you're considering non-European ancestry it is the almost completely brown eye colour."
At some point, you've probably wondered what the rarest eye color is. The answer is green, according to the American Academy of Ophthalmology (AAO). Only about 2 percent of the world's population sport this shade.
Do you have brown eyes? Well, consider yourself lucky – or maybe unlucky – because you have the most common eye color in the world! Being one of the popular kids isn't the only benefit of brown eyes, some studies have actually suggested that men with brown eyes seem more trustworthy than their blue eyed counterparts.
