Hazel eyes, one of the more mysterious eye colors, are as unique as they are beautiful. But what’s the science behind this one-of-a-kind eye color? Is having hazel eyes common or rare? And why is it that they seem to change color? Here’s the truth about hazel eyes.
Whereas people with brown, blue, and green eyes usually only appear to have one color in their iris, people with hazel eyes have several. Additionally, having hazel eyes is less about color and more about how color is distributed within the iris. And that can have some significant variation, as there’s a lot at play when it comes to how hazel eyes appear.
Specifically, the hazel pattern begins with a ring of color around the pupil, usually brown. Then, as you move away from the pupil and out toward the rest of the eye, the color will shift into green, sometimes with an additional ring of amber in between. This burst-like pattern is what makes hazel eyes distinct from green ones, which don’t have the same kind of color shift and are monochrome in appearance.
That’s not to say that people with different eye colors can’t have variation in their irises, as they certainly can. But this unique variation is how it works for the hazel-eyed folks out there. Keep watching to learn The Truth Behind Hazel Eyes!
