To most people eye color means nothing more than the hair color or the size of a person’s ears. In fact, it’s quite logical to believe so. But, when it comes to blue-eyed people, science has some interesting facts to reveal.
Blue eyes don’t have a set color. In fact, they get their color from the light available when you look at them. To be more specific, each eye has the iris, which is made up of two different layers – the epithelium in the back and the stroma in the front. The epithelium, which is just two cells thick, is made up of black-brown pigments. When the epithelium shows through, it results in dark specks in the eyes.
The stroma, on the other hand, is made of colorless collagen fibers. It sometimes contains the pigment melanin, and sometimes excess collagen deposits. These two things, melanin and collagen, actually determine the color of a person’s eyes.
According to Science Alert:
“Blue eyes are potentially the most fascinating, as their color is entirely structural. People with blue eyes have a completely colorless 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. Interestingly, this means that blue eyes don’t actually have a set color — it all depends on the amount of light available when you look at them.”
A Danish researcher found that there’s a kinship between every blue-eyed person in the world. According to study results, all humans existing 6,000-10,000 years ago had brown eyes. Blue eyes first appeared thousands of years ago due to a mutation that caused some people to have blue eyes as found in a DNA testing. What’s most startling is the fact that blue-eyed people have all probably descended from that first blue-eyed ancestor.
“New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.”
As far as personality goes, the blue eye color is so lively and appealing that immediately attracts other people. It’s no wonder it’s the most desirable eye color in the world. Blue-eyed people tend to be peaceful, clever, generous and full of youth and life. They have long-lasting relationships and are full of energy. What’s unique about this group of people is their natural need to make other people happy. With their kindness and honesty, they always try hard to put a smile on your face. It’s probably this that makes blue-eyed people so attractive to other people.
They really enjoy observing and contemplating on things. Blue-eyed people are normally socializers that want and devote themselves to a long-lasting and full-commitment relationship. When they get one such relationship, they have no limits in making their significant other happy.
