Gray eyes may protect against certain skin disorders and autoimmune diseases. If you've got gray eyes, you are less likely to suffer from a skin disorder called vitiligo, a condition in which your immune system attacks cells with melanin pigment and leaves behind irregular patches of white skin.
Protection Against Disease. Grey eyes may mean greater protection against certain skin or autoimmune disorders. Researchers think people with grey eyes are less likely to have vitiligo. This is a skin disorder that is associated with diabetes, arthritis, and lupus (among other things).

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.
Grey eyes personality traits
What do grey eyes mean for your personality? the ancient Greeks associated grey eyes with wisdom. grey eyes can be associated with strategic thinking. some say that grey-eyed people are more competitive. men with grey eyes are seen as more faithful.
Of all eye colors, brown seems to be the only one that could be called “advantageous” from a survival perspective. While more research is needed, darker irises are linked to a number of health benefits, including these: Reduced risk of macular degeneration. Lower melanoma risk.
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.
The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.
Gray. Close to 3% of the world's population have gray eyes. People with gray eyes have little or no melanin in their irises, but they have more collagen in a part of the eye called the stroma. The light scatters off the collagen in a way that makes the eyes appear gray.
What ethnicity has GREY eyes? Gray eyes are typically found among people who are of European ancestry, especially northern or eastern European. Even among those of European descent, gray eyes are pretty uncommon numbering less than one percent out of all human population.
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.
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.
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).
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.
Gray: The Rarest Eye Color
New classifications have determined that gray is its own standard color. 1 (It was previously, and incorrectly, lumped in with blue.) With this change, gray now tops the list as the rarest eye color.
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.
Most people from Finland and Baltic people have gray and grayish-blue, grayish-green eyes.
Having gray eyes is one of the rarest physical conditions in the human race. The color is caused by the front layer of the iris having less melanin than the back layer.
Silver (grey) eyes: A grey-silver colour is quite rare and occurs as a result of virtually no melanin in the iris. Silver eyes are considered to be one of the rarest colours around the world, but when they do occur, this is most often seen in eastern Europe areas.
Like blue eyes, silver eyes are the result of a very low amount of pigmentation in the eye, which reflects a gray-silver appearance. Silver eye color is most common in eastern European countries, and is one of the rarer eye colors worldwide.
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.
Your children inherit their eye colors from you and your partner. It's a combination of mom and dad's eye colors – generally, the color is determined by this mix and whether the genes are dominant or recessive. Every child carries two copies of every gene – one comes from mom, and the other comes from dad.
Each parent will pass one copy of their eye color gene to their child. In this case, the mom will always pass B and the dad will always pass b. This means all of their kids will be Bb and have brown eyes. Each child will show the mom's dominant trait.
Low wavelength colors promote restfulness and calm, and they improve efficiency and focus. So that's why green is an excellent color for improving concentration.
Although brightness may be an issue for light-eyed people, it's not directly related to the quality of their eyes and eyesight. In general, science has not found evidence that people with darker eyes have inherently better vision than those with paler irises.
Retina damage: Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells. This can cause vision problems like age-related macular degeneration.
