Did you know that green eyes are one of the rarest eye colours in the world? If you're lucky enough to come across one, you're looking at a phenomenon as fascinating as it is unusual. Around 2% of the world's population has this unique colour. But why is it so rare, and where does this captivating hue come from? Here are some fascinating facts about green eyes.
The origin of green eyes
Eye colour is determined by the amount and type of pigments, particularly melanin, present in the iris and the way light diffuses through these pigments. Green eyes result from a low level of melanin, combined with a light-scattering effect known as Rayleigh scattering. This phenomenon creates a greenish appearance when light enters the eye. Unlike brown eyes, where melanin is dominant, or blue eyes, where there is very little, green eyes are a harmonious blend of both.
A unique geographical distribution
Green eyes are rare worldwide but more common in specific regions. Northern and Western Europe, particularly Ireland, Scotland, Iceland, and parts of Central Europe, are home to a higher number of green-eyed people. However, most of the world's populations, notably in Asia, Africa, and Latin America, are predominantly brown-eyed.
Green eyes and genetics
The genetics of green eyes are still somewhat mysterious, as multiple genes influence them. In the past, eye colour was thought to follow a simple pattern of genetic dominance, with brown eyes dominating over blue or green eyes. However, recent research has revealed that multiple genes determine eye colour, making the combinations more complex. This is probably why green eyes are so rare: they only result from the right, relatively rare genetic combination between parents.
The myth and magic of green eyes
Green eyes have long been shrouded in mystery and superstition in some cultures. They are often associated with mystical qualities or even witchcraft in folk tales. In ancient times, people with green eyes were sometimes considered to have special, even evil, powers. Today, they are seen as captivating and exotic, contributing to the singular appeal of those who wear them.
Rarity attracts attention
There's no denying that the rarity of green eyes makes them particularly intriguing. While only 2% of the world's population has green eyes, this rarity makes them all the more special. Many green-eyed celebrities, such as Emma Stone or Adele, are often admired for their hypnotic looks, adding to the mystery and beauty of this eye colour.
Whether you have green eyes or are simply fascinated by this unique colour, they are undoubtedly among the rarest and most beautiful in the world. Their rarity, complex genetic origin, and cultural symbolism make them an eye colour that attracts attention and fascinates through the ages.
