Green Eyes People – Eye colour is a polygenic phenotypic trait determines by two distinct factors: the pigmentation of the eye’s iris and the frequency dependence of light scattering by the turbid medium of the iris matrix.
In humans, iris pigmentation varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located behind the iris) and melanin content in the iris matrix (located in front of the iris). And the cell density of the matrix. The appearance of blue, green, and brown eyes results from Tyndall’s scattering of light in the stroma. A phenomenon similar to explaining the blue colour of the sky, called Rayleigh scattering.
Green eyes can result from the interaction of OCA2 and several variants within other genes. They existed in Southern Siberia during the Bronze Age. They are more common in northern, western and central Europe. In Scotland, 29% of people have green eyes. In Iceland, about 8-10% of men, about 18-21% of women, 6% of men and about 17% of women in the Netherlands have green eyes.
Among European Americans, green eyes are the most common among recent Celtic and Germanic ancestry, accounting for about 16%. In addition, 40.8% of Italians in Verona, 22.5% of Spaniards in Alicante and 15.4% of Greeks in Athens have green, grey and blue eyes. But overall, green considere the rarest natural eye colour. Only 2% of the world’s population has it.
The green colour causes by 1) the amber or light brown pigment of the iris stroma (low or moderate melanin concentration) and a combination of 2) Blue tint produced by Rayleigh scattering of reflected light. In addition, green eyes contain the yellow pigment lipochrome.
Green eyes: The Most Beautiful Eye Colour?
If you have green eyes colour, you have good reason to rejoice.
Although green often associates with envy (even Shakespeare’s character in Othello calls jealousy a “green-eyed monster”), many consider green the most attractive eye colour.
Here are my preferences from over 66,000 responses:
- Green: 20.3%
- Sky Blue: 16.9%
- Hazelnuts: 16.0%
- Dark Blue: 15.2%
- Gray: 10.9%
- Honey: 7.9%
- Amethyst: 6.9%
- Brown: 5.9%
One of the charms of green eyes may be their rarity. Unfortunately, reliable statistics on the distribution of eye colour are difficult to obtain, but according to some sources, the global prevalence of green eyes is only 2%.
However, the prevalence of green eyes varies widely by geographic region and country, with the highest concentration in northern and central Europe.
For example, in Edinburgh, Scotland, about 29% of the inhabitants have green eyes (57% have blue eyes, and only 14% have brown eyes).
According to Iceland’s census, 89% of women and 87% of men have blue or green eyes.
What Causes Green Eyes?
Although genetics plays a role in determining eye colour, it is almost impossible to predict a child’s eye colour with 100% accuracy just by knowing the parent’s eye colour.
This is because many, unlike genes, involves in the inheritance of eye colour, and different interactions and expression levels of these genes can alter eye colour outcomes in children.
The structure inside the eye responsible for eye colour is called the iris. It is a thin, circular structure surrounding the pupil. In addition to regulating the size of the pupil and thus the amount of light entering the eye, the iris contains pigment cells that determine the colour of the eye.
But here’s what’s interesting: There are many different eye colours, but surprisingly few types of eye pigments are available. Instead, almost all eye colour is determined by the amount of a brown pigment called melanin in the cells of the iris.
So how does brown pigment make green eyes, blue eyes, hazel eyes, or any other eye colour other than brown?
The conversion in eye colour is due to different amounts of melanin pigment granules in the iris cells called melanocytes. These cells acquire a genetically determined amount of melanin during childhood, and the melanin content usually remains relatively constant throughout life.
People with low melanin in the melanocytes of the iris have a lighter eye colour (such as blue or green) than people with high melanin levels who are more likely to have brown eyes.
However, additional factors are involved in determining eye colour, especially the different shades of green and blue eyes. When light hits the iris and pigmented melanocytes in the iris, the light is scattered and reflected.
This phenomenon, called Rayleigh scattering, can produce different reflective colors depending on the physical structure of the iris and the amount of melanocytes and melanin density in the melanocytes.
Depending on these variables, Rayleigh scattering (the same phenomenon that makes a cloudless sky look blue) can produce different shades of blue, green, brown, etc.
It can also be challenging to classify specific eye colours based on the structure of the iris and the distribution of melanocytes within it.
For example, some “green” eyes have Hazel or brown crowns near their pupils, which can sometimes appear Hazel and at other times green, depending on the lighting, makeup, and the colour of the clothing a person is wearing.
Green Eyes Celebrities
Does green-eyed allure help attract the attention of artists and other celebrities? maybe.
Here is a short list of actors, singers, and other celebrities who may be attracted to green eyes.
Adele, Adrien Brody, Daniel Day-Lewis, Katie Holmes, Terrence Howard, Kate Hudson, Scarlett Johansson, John Krasinski, Leona Lewis, Lindsay Lohan, Kate Middleton (Catherine, Duchess of Cambridge). Also, Clive Owen, Joaquin Phoenix, Eddie Red Maine, Rihanna, and more
Improve Eye Colour
If you want green eyes instead of your natural eye colour, it is recommended to wear coloured contact lenses.
If you are blessed enough to have perfect vision naturally, several brands and shades of green contact lenses are available, including uncorrected lenses.
Also, if you naturally have green eyes and wear glasses, lenses with an anti-reflection (AR) coating. Which will help bring out the green eye colour. The AR coating removes the distracting glare of your glasses. Allowing others to see the beauty and expressiveness of your green eyes.
No matter your eye colour, they are truly unique and can never be duplicated. Like snowflakes, they are beautiful because each eye has different characteristics, regardless of the colour of the eyes.
Difference Between Green Eyes and Hazel Eyes
Although there are distinct differences between green eyes and brown eyes, it is easy to confuse them with each other. This is because green eyes usually have a monochromatic green tint with more or less single colour across the iris. Hazel’s eyes are multicoloured, with shades of green and a characteristic lustre of brown or gold radiating outward around the pupil.
The Science Behind Green Eyes
Green Eyes People and blue pigments are rare in animals. However, some animals, such as snakes and peacocks, have bright shades of blue and green. Thry have no green or blue pigment. These animals have unique microscopic structures that scatter light in a way that makes them appear green or blue to humans.
This phenomenon that produces structural colour is called Rayleigh scattering. It is also used to explain why the sky is blue. The human eye also uses these hacks to create green and blue eye colors.
Sunlight appears white to the naked eye but is a mixture of many colours. This is because the matrix molecules inside the human eye’s iris have a special structure that scatters light in a way that makes the iris appear blue.
