The Science Behind Brown Eyes

Current estimates suggest that between 65-80% of the world’s population has brown eyes. So, while being a brown-eyed beauty may not be as unique as you’d like, bear in mind that not all shades of brown are the same.

If you’re from southern Europe, Africa, the Middle East, or East Asia, there is a higher likelihood of brown eyes running your family. It used to be believed that eye color came from your father, but newer research indicates that as many as 16 different genes may affect the color you’re born with.

One of the benefits of being brown eyed is that you’re less likely to suffer from the effects of harmful sun radiation. Generally speaking, people with high concentrations of melanin are less likely to develop certain types of skin or eye cancer. This does not mean you’re immune from sun damage, it just means you may be luckier than your blue-eyed companion.

Another interesting statistic is, according to Scientific American, brown-eyed individuals tend to be perceived as more trustworthy than blue- or green-eyed individuals. What’s more, is the myth of brown eyes changing color isn’t really a myth. Many factors can affect the shade of the brown color in eyes, including:

  • The time of day
  • Lighting
  • Clothing and reflective colors
  • Makeup and bronzers
  • Substances like alcohol or marijuana
  • Mood

No matter what way you spin it, brown eyes are beautiful and interesting physical characteristics – something to be proud of!
