Less than 3% of the global population has grey eyes. They're most commonly found in people of Northern and Eastern European ancestry. Like all eye colors, they're a product of the amount of melanin in the iris. People with light-colored eyes have very little melanin compared to those with brown-colored eyes.
Most people from Finland and Baltic people have gray and grayish-blue, grayish-green eyes.
Grey eyes are amongst the rarest eye colours and while many associate grey eyes with being blue, they are not quite the same despite them both having low levels of melanin. Pink and pale red eyes are also incredibly unusual eye colours and occur in people who have albinism.
There are likely to be other genes that cause differences in how much melanin is made and where in the iris it is made. Ultimately there are at least two things that could determine gray eye color. The first is the amount of melanin made. And the second is the density of the proteins in the stroma.
Gray eyes are neither recessive nor dominant. Scientists used to think that a person's eye color was caused by one dominant gene, and that brown eyes were dominant while lighter eyes (blue, green, hazel and gray) were recessive. A recessive gene only shows up when there are two copies of it present.
They're most commonly found in people of Northern and Eastern European ancestry. Like all eye colors, they're a product of the amount of melanin in the iris. People with light-colored eyes have very little melanin compared to those with brown-colored eyes.
If you have gray eyes, the front layer of the iris has less melanin than the back layer, so external light passes through, and the back layer reflects it. The reflection causes a cloud in the stroma, which may manifest as a gray, blue, or green iris.
What color will gray baby eyes turn? At birth your baby's eyes may appear gray or blue due to a lack of pigment. Once exposed to light, the eye color will most likely start to change to blue, green, hazel, or brown over a period of six months to one year.
Gray eyes may be called “blue” at first glance, but they tend to have flecks of gold and brown. And they may appear to “change color” from gray to blue to green depending on clothing, lighting, and mood (which may change the size of the pupil, compressing the colors of the iris).
Their low melanin content is similar, but in fact, gray irises are significantly more rare than standard blue eyes. If you look closely, you might even spot streaks of brown, amber and gold within the gray. Even less common is a condition called heterochromia — different colored eyes.

One of the study's main findings was that gray eyes are both the rarest and the statistically most attractive eye color, with hazel and green following closely behind. Conversely, brown eyes are the most common color yet the least attractive to the survey's respondents.
Despite songs about blue eyes and brown-eyed girls, neither were found to be the most attractive eye color. Instead, gray eyes topped the chart with an average rating of 7.4, followed by blue and green eyes each scoring an average of 7.3.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
"In Australians of European ancestry, the percentage of eye colours are 45 percent blue-grey, 30 percent green-hazel and 25 percent brown. If you're considering non-European ancestry it is the almost completely brown eye colour."
Gray is the second-rarest natural eye color after green, with 3% of the world's population having it.
Generally speaking, patients with lighter color irises, such as blue or gray, experience more light sensitivity than someone with brown eyes. The density of pigment in light eyes is less than that of a darker colored iris. When light hits a dark-colored iris, the higher density in pigment blocks the light rays.
Green eyes are rarer than gray eyes, but only by 1%. Around 3% of the world's population has gray eyes. Like blue eyes, gray eyes are caused by a lack of melanin in the iris.
If you have grey eyes, you tend to be gentle, friendly and approachable by nature. You also may find you are rather neat and tidy, however you don't fuss too much over it. Out of all they eye colours, most tend to confide in you grey eyes beauties and therefore tend to be very trust worthy and a great listener!
Most babies with lighter skin are born with blue or grey eyes. Some stay blue or grey while others gradually change over time to green, hazel or brown. Most, but not all, babies with darker skin are born with darker eyes that stay brown.
It's a myth that all babies are born with blue or gray eyes. While some babies are indeed born with blue or gray eyes that stay that color or gradually change, others are born with brown, green or hazel eyes. In fact, most babies are born with brown eyes that stay brown.
A recent survey conducted by CyberPulse, a division of Impulse Research Corporation in Los Angeles uncovered this colorful research. Intelligence was the number one trait associated with brown, the most common eye color in the U.S., by 34 percent of respondents.
Blue eyes are crowned the sexiest among men and women
According to our research, blue is the sexiest eye colour, as the majority of the world's sexiest people, both male and female, have blue eyes.
Blue is the most attractive or beautiful eye colour, but only for some people, research finds. Blue-eyed males are particularly attracted to blue-eyed females, the researchers found. However, women showed no preference for blue or brown-eyed men and brown-eyed men showed no preference either.
