The most common or "normal" eye color, in terms of prevalence across the global population, is brown.
Prevalence of Brown Eyes
Brown eyes are found in more than half of the world's population. This widespread occurrence is due to the higher production of melanin in the iris. The shade of brown can vary significantly, ranging from light amber to deep dark brown, further contributing to its commonality.
Why Brown Eyes are Common
- Melanin: The amount of melanin (a pigment) in the iris determines eye color. Higher melanin levels result in brown eyes.
- Genetics: Brown eyes are often a dominant genetic trait. This means that if one or both parents have brown eyes, there's a higher likelihood of their children also having brown eyes.
- Global Distribution: Brown eyes are prevalent in many parts of the world, including Africa, Asia, and parts of Europe and the Americas.
Other Eye Colors
While brown is the most common, other eye colors include:
- Blue: Lower melanin levels result in blue eyes.
- Green: A combination of melanin and the way light scatters in the iris creates green eyes.
- Hazel: Hazel eyes are a mix of brown, green, and gold.
- Gray: Very low melanin levels and light scattering can result in gray eyes.
Therefore, while "normal" can be subjective, brown is the most statistically common eye color worldwide.
