Why did my eyes turn green?

If you’ve recently noticed a change in the color of your eyes, particularly from brown or blue to green, you may be wondering what on earth is going on. Fear not my friend, for I am here to explain this biological anomaly that has fascinated and confused humans for years.

Is It An Alien Invasion?

First things first – it’s not an alien invasion. Though we wouldn’t rule out extraterrestrial involvement entirely (who knows what those sneaky aliens are capable of), the truth lies much closer to home.

Genetics Is The Culprit

The color of our eyes is actually determined by genetics. That’s right folks – it’s all in our genes! Eye colors range from deep browns and blues to greens and hazels depending on the amount of melanin present in the iris. Melanin is a pigment responsible for determining skin and hair color as well.

So What Does This Mean For Me?

Well, simply put – if both parents have brown eyes but carry a recessive gene for green eyes, there’s a chance their child will inherit that gene even though neither of them expresses it visually. In other words, genetics can throw up some surprises!

A Quick Science Class: Dominant And Recessive Genes

Every individual inherits one copy of each gene from their mother and another copy from their father for every trait which they exhibit How these genes interact with each other determines which traits are expressed and how they look.

Dominant genes overpower any possible effect caused by mutations or alleles while recessive ones get drowned out when matched with dominant partners .

In simple terms – two people with different recessive eye-color genes who have children together could technically pass both onto their offspring producing children born with rare eye-colours such as violet or amber!

But genetics isn’t always so predictable; sometimes certain traits can skip generations only reappearing many years down the line.

The Role Of Melanin In Eye Color

Melanin is a pigment that determines more than just eye color – it also affects skin and hair color as well. A person with more melanin in their iris will have darker eyes, while those with less melanin develop lighter-colored irises.

However, there are different types of melanin present in human eyes, which helps determine the exact shade of green our eyes turn. For example, those without much blue or brown pigment have yellow-greenish tones to their iris producing olive green or lime-teal colours

Those who inherit plenty blue-coloring genetically but little brown may have brighter coloured green such neon-lights-dark-green ones

It’s all about how pigments mix.

Fun Fact Alert: African And Bengal Cats Share Green Eyes With Humans

In terms of fellow species sharing this genetic oddity – two animals stand out; Bengals and Africans cats share bright green-eyes like humans!

They carry mutant genes causing an abundance collagen influx in stromal layer around cornea , lending them lenses reflective enough for vivid emerald hues .

So if your feline friend’s got some strikingly colored peepers then you know why.

Environmental Factors Have No Tomfoolery Here

You might ask ‘What about environmental factors? What role do they play?’
Well sorry folks- environmental influences don’t really interfere when we talk about modifying existing hue — though Yes! external conditions may alter growth patterns affecting their degree of sensitivity making us perceive them differently for instance sunlight can make colour look brighter however once again this doesn’t impact actual unique coloring itself fundamentally .

Sorry to disappoint any conspiracy theorists out there – looks like chemtrails aren’t responsible for your sudden change in eye color after all (sighs).

So How Rare Is This Phenomenon?

Green-eyed people are believed to be rarer than any other types of colored sheerly for the fact that no single viable dominant gene exists for such colors. According to research, only 2% of people in the world have green eyes and although this number may seem small – it still means there are roughly around 150 million green-eyed individuals out there!


In conclusion , a shift resulting from genetic variations influences how much melanin our iris adds, which accounts for our eye color displaying or shifting various degrees of greens.

So if you happen to notice your brown-eyed pals turning green with envy over your new genetically-induced olive-tones or if someone tries telling you that drinking large amounts of carrot juice turned their eyes green overnight (rolls my eyes) – Know what really causes those lush evergreens…genetics!
