No one in the world has the same eye color as you. But if you are lucky enough to have sky blue eyes, you are even more special and unique. And as it turns out, those with blue eyes can have real superpowers.
Blue eyes aren’t actually blue.
There is no blue pigment in the eyes. The majority of the human race gets its brown eye color from melanin – the pigment responsible for skin color. But when it comes to blue eyes, they get their color as a result of light reflection. It’s the same thing that makes the ocean and sky look blue.
They can change color.
Blue eyes can be different colors depending on the light conditions. This is because they get their color from light coming in and then being reflected back out. You can also slightly change the color of your eyes and make them look brighter or duller depending on the makeup you choose.
All blue eyes have the same ancestor.
A team of scientists at the University of Copenhagen discovered that all people with blue eyes may be related. Somewhere between 6,000 and 10,000 years ago, everyone had brown eyes, but at some point, the gene that controls the level of melanin mutated. This mutation limited the amount of melanin we could produce and “diluted” brown eyes to blue. All blue-eyed people have inherited this genetic “switch” at exactly the same spot in their DNA.
Blue eyes are very rare.
The majority of people have brown eyes, while only 8% to 10% are lucky enough to have blue eyes. According to the World Atlas, the majority of bluefins live in Europe. Finland has the highest percentage of people with blue eyes.
Many babies are born with blue eyes that will change later.
When a baby is born, you can’t know what color his eyes will be when he grows up. At the time of birth, babies have no melanin in the iris – the part of the eye that determines eye color. After 6 months, the babies’ genes determine how much melanin will be in the iris. Depending on this, the eyes may remain blue or become gray, green or brown.
Blue-eyed people are more sensitive to light.
If your eyes are light-colored, you need to be extra careful when protecting them from the sun. Ophthalmologists believe that people with blue irises tend to be more sensitive to light. Because blue eyes do not have enough light-absorbing pigment, more light can pass through the iris and damage the eye.
People with blue eyes handle pain better.
People with light colored irises are lucky enough to have a higher pain tolerance than people with dark eyes. A researcher at the University of Pittsburgh looked at 58 expectant women and found that women with blue or green eyes experienced less pain and coped better with childbirth. It is believed that genes associated with melanin may strongly influence pain tolerance.
