Green Eyes (Pictures, Genetics & Facts) (2024)

Key Takeaways

  • Green eyes are caused by reflected light combined with low levels of melanin in the iris. There’s no actual green pigmentation in the human eye.
  • Green is the rarest eye color. This may be why green eyes are considered desirable and green-eyed people are perceived as mysterious.
  • Having green eyes won’t affect your vision or your candidacy for LASIK eye surgery.

What Causes Green Eyes?

Human eye color is determined by the level of melanin pigmentation in the iris. Your iris is the thin, ring-like structure in the middle of your eye, giving it its color.

Scientists used to believe eye color was decided by two genes—one from each parent. Now, they know as many as 16 genes influence the amount of melanin produced by the iris. These genes interact in complex ways, making it impossible to predict the color a baby’s eyes will be.

Melanin absorbs light, so irises with high amounts of melanin appear darker. The light that doesn’t get absorbed gets reflected back as short blue wavelengths, giving eyes their color.

Green eyes appear green because reflected light mixes with low levels of melanin in the iris, not because they contain green pigment.

  • Brown eyes. Have a lot of melanin. They absorb a lot of light, which makes them dark in color.
  • Hazel eyes. Have less melanin than brown eyes, so they appear lighter.
  • Green eyes. Have less melanin than hazel eyes but more than blue.
  • Blue eyes. Have the least amount of melanin and reflect the most light. This makes them the lightest eye color.

Light reflecting off the irises can make it seem like some people’s eyes change color in different settings.
