People have strange ideas about eye color. There is a common perception about people with eyes like Chatkabri or Kanchas that they are unfaithful and unfaithful.
There is a similar perception about blue-eyed people. You must have heard the song “Ik Bay Wafa Se Pyaar Kya, Usse Nazar Ko Char Kya” from Aa Jahani Raj Kapoor and Nargis’ fight in the movie “Awara“. In her interlude, the heroine says, “De Gaye Dukha Us Neli Neli Aanhan” meaning that those with blue eyes are deceivers.
It is not known whether blue-eyed people are deceivers or not, but experts say that the color of blue eyes in any person is not a disease, but the fact that all these people are descended from one European. This habitation must have occurred sometime between 6,000 and 10,000 years ago.
Experts say that initially many people’s eyes were only brown, but then time began to change the color and they became completely blue.

Experts say that this change in eye color is caused by a gene called HERC2. This causes the eyes to turn blue. On the basis of research, it is being said that all people with blue eyes are from the same race because the variation found in the color of the eyes of these people is of the same nature. Around 8 to 10 percent of people worldwide have blue eyes. .

Debunking Eye Color Myths: Unraveling the Mystery of Blue Eyes
For centuries, people have held strange beliefs about eye color, often linking certain colors to specific personality traits or characteristics. In many cultures, people with blue eyes have been perceived as unfaithful or deceitful, as seen in the classic Bollywood movie “Awara” where the heroine sings about blue-eyed individuals being deceivers. But what’s the truth behind these myths? Let’s dive into the fascinating world of eye color genetics and uncover the secrets of blue-eyed individuals.
The Genetic Roots of Blue Eyes
Research suggests that blue eyes are not a disease, but rather a genetic variation that originated from a single common ancestor in Europe [[2]]. Scientists have traced this genetic mutation back to around 6,000 to 10,000 years ago, a time when the human population was smaller and more localized [[2]]. This means that all blue-eyed individuals share a common ancestor, making them part of a distinct genetic lineage.
The Evolution of Eye Color
Initially, human eyes were predominantly brown, but over time, genetic variations led to changes in eye color [[3]]. The OCA2 gene, responsible for melanin production in the eyes, plays a crucial role in determining eye color [[1]]. A single genetic difference in this gene is the most common cause of blue eyes, indicating that blue-eyed individuals have low concentrations of melanin in their eyes [[1]].
A Single Common Ancestor
Studies have confirmed that all blue-eyed individuals, regardless of their geographical origins, share a common genetic ancestor [[2]]. This ancestor likely lived in Europe, where the mutation first occurred, and was then passed down through generations, spreading to different parts of the world.
Myths and Misconceptions
The notion that blue-eyed individuals are unfaithful or deceitful is purely a cultural myth with no scientific basis. Eye color is determined by genetics, not by a person’s character or behavior. It’s essential to separate fact from fiction and recognize that people with blue eyes are just as diverse and complex as those with any other eye color.
Conclusion
the color of blue eyes is not a reflection of a person’s character or behavior, but rather a genetic variation that originated from a single common ancestor in Europe. By understanding the science behind eye color, we can dispel harmful myths and misconceptions, embracing the diversity of human experience. So, the next time you meet someone with blue eyes, remember that they’re not inherently deceitful – they’re just carrying a unique genetic trait that makes them who they are.
