Green Eyes Trivia – 10 Fun Facts About Green Eyes

  1. Green eyes are very rare.
    Green eyes are the most rare eye color in the world. Only about 2 percent of people in the world have naturally green eyes. Green eyes are a genetic mutation that results in low levels of melanin, though more melanin than in blue eyes.portrait of green eyed woman
  2. Green eyes don’t actually have any color.
    That’s right – strange but true! While green eyes appear that lovely shade of emerald to the outside observer, the irises themselves have no actual pigment. Similar to blue eyes, the color we perceive is a result of the lack of melanin in the iris. The less melanin in the iris, the more light scatters out, which makes the eyes look green. Ever heard from someone that their eyes change color? Turns out, it’s somewhat true. Changes in light make lighter eyes look like they are changing colors, sort of like a chameleon.
  3. Where in the world are the most green eyes?
    The highest concentration of people with green eyes is found in Ireland, Scotland, and northern Europe. In fact, in Ireland and Scotland, more than three-fourths of the population has blue or green eyes – 86 percent!
  4. Many factors go into having green eyes.
    Sixteen separate genes have been identified as contributing to eye color. So, no matter what eye color your parents have, yours could end up being just about any color. Green eyes naturally occur in all races of people.

  5. Liqian, China is a hot spot for green eyes.
    There is a village in China called Liqian, in which two-thirds of all inhabitants today have green eyes and blonde hair. Green eyes and blonde hair are a rare combination. The high concentration of green-eyed, blond-haired people in Liqian is thought to be linked to their ancestry. The people of Liqian are thought to have possibly descended from Roman General Marcus Crassus’ mysteriously missing army.
  6. Babies don’t get green eyes immediately.
    Every baby is born with either brown or blue eyes. It can take between six months and three years for children to develop green eyes.baby sitting in the grass 
  7. Can green eye color affect personality?
    This particular topic may all be in the eye of the beholder (punny, huh?). There is no scientific data to prove that eye color is a factor in determining personality, and we will go on record as saying eye color does not affect personality. However, just for fun – here are some personality traits that have historically been associated with green eyes in fables and folklore: intelligence, passion, mysteriousness, creativity, jealousy, and great leadership skills.
  8. Grab your shades.
    Because green eyes have less melanin than brown eyes, people with green eyes are more likely to be extra sensitive to UV rays. The more melanin, the better protection from the sun – eye pigment literally protects the retina. Like blue-eyed people, those with green eyes are more sensitive to sudden increases in light.
  9. Green eyes are popular in pop culture.
    Green eyes may be the most rare of all natural eye colors, but you’ll see green peepers all over the silver screen. Green eyes are also incredibly popular in books. Some well-known green-eyed characters in books and movies include:
      • Harry Potter – from the Harry Potter book series by J.K. Rowling
      • Mary Jane Watson – The Amazing Spider-Man comics
      • Batgirl – DC Comics
      • Catwoman – DC Comics
      • Loki – Marvel Comics
      • Petyr Baelish – A Song of Fire & Ice by George R.R. Martin
      • Scar – The Lion King
      • Jane Eyre – Jane Eyre by Charlotte Bronte
      • Rapunzel – Disney’s Tangled
      • Asami Sato – Legend of Korra
  10. Green eyes don’t affect LASIK candidacy.
    No significant link has been found between eye color and quality of vision. Green-eyed people can have myopia (nearsightedness), astigmatism, or hyperopia (farsightedness), just like people with any other eye color. Green-eyed people can also have LASIK vision correction. LASIK does not affect eye color. That’s great news for anyone with green eyes who wants to say goodbye to the hassles of glasses and contact lenses. Considering LASIK?

Yes, it definitely can! That’s why wearing sunglasses with UV protection is so important – both to protect our eyes and to provide more comfort while outdoors.

Your comments about babies not having green eyes immediately is incorrect. I have eyes the color of dark green jade. My parents told me they were startled to see my eyes were green and not blue as soon as I opened them. They never changed. Also the whites of my eyes were slightly green, the same ways some babies’ eyes have bluish whites right after birth. So green eyes do not necessarily show up later. I was also born a very fair skinned, golden blonde. My hair stayed that color until puberty, when it darkened.
