Blue eyes are stereotypically seen as desirable in society for their uniqueness and beauty. But chances are, if you've been living with blue eyes, you've been the victim of some misinformation.
Don't worry – it's nothing serious, but all is not as it seems.
via: GuffScientific studies show that you might have been bamboozled your whole life.
Blue eyes are actually a genetic mutation.
via: GIPHYNo, not that kind of mutation. Unfortunately, it doesn't mean you have superpowers if you have blue eyes. Genetic mutation is just a permanent change in the DNA sequence that makes up a gene.
Amazingly, the gene for blue eyes has been traced back to a SINGLE person who lived between 6,000 and 10,000 years ago.
via: GuffThe common math has told us that from this one person, now 1 in 6 people live with blue eyes.
But, actually, no one has blue eyes.
via: GuffBlue eyes are brown. Yup. Even those really piercing blue ones. You've probably got some questions...
Actually, all eyes are brown. Green eyes and hazel eyes are...brown.
via: GuffYou're probably wondering why they don't look brown. At all. Well, there's a pretty good reason for that.
The color of your eyes is determined by melanin, a pigment that also appears in your skin and hair.
via: GuffThe presence of melanin in the iris gives eyes their color.
But the pigment only comes in one shade.
via: GuffSays Dr. Gary Heiting, "Everyone has melanin in the iris of their eye, and the amount that they have determines their eye color. There's really only (this) one type of pigment."
And that pigment itself is...you guessed it — brown.
So although eyes might "appear" to be a color, they're just loaded up with brown pigment to various degrees.
Got all that?
via: GIPHYOkay good, because it's about to get even more complicated.
It turns out that there's some complicated interaction between the pigment and the iris that leads to brown eyes.
via: GuffSays the good doctor, "It's an interaction between the amount of melanin and the architecture of the iris itself" that can cause a brown pigment to appear hazel, green, or...well, brown.
The less melanin you have, the more blue your eyes look.
via: GuffThat's why they're the lightest. Green is halfway and brown eyes are heavy on melanin.
This is why eye color can change.
via: GuffNot only does it change as different types of light at different angles hit them, but it also can change as people age and the amount of pigment varies.
That's why so many babies' eyes look blue early in life, then change.
via: GuffThe fact is that they don't "have" blue eyes, they just haven't developed all their melanin yet. They get it later on and their eyes change color, getting darker.
So, no matter what color eyes you're looking into...
via: Guff...remember they're all brown. We just see them different ways!
