Blue eyes are not considered a rarity, but each owner is special.
The human body does not have blue pigment
If you are blue eyes, this only means that the body has a reduced production of melanin, which stains the eyes in a brown shade.The color of the eyes appears blue due to light reflection and the fact that collagen fibers are whitish in color.
Blue eyes change color
Since hue is largely formed due to light reflection, the hue will also change under different lighting conditions.
A common ancestor is present
Researchers from Copenhagen believe that earlier in humans, eyes were only brown, and then the gene responsible for the level of melanin mutated.
This happened somewhere between 6,000 and 10,000 years ago. All blue-eyed people inherited this mutation and retained it in their DNA.
Blue people are more sensitive to light.
You definitely need to wear glasses in the summer, because due to the light iris and the lack of melanin inside more light enters, the likelihood that ultraviolet light will damage eyesight increases with prolonged impact.People with blue eyes tolerate pain better
In Pittsburgh, they tested women with which eye color better tolerate pain during childbirth. It turned out that blue-eyed people do it best.
