Genetics ? Which is the rarest eye color in humans? 10) Brown eyes Do you remember Bob Marley's song “Looking in your big brown eyes”? Brown is the most common eye color. In fact, in some parts of the world, it would be incredibly difficult to find people with different eye color. Brown eye color is connected with a high amount of pigment called melanin. This might cause some health benefits: people with brown eyes are less likely to suffer from age-related macular degeneration, which may affect visual acuity. However, there are also downsides of having dark eyes. The researches show that women with brown eyes are more likely to be depressed than those with paler eyes.
People with brown eyes are considered to be more trustworthy. University students in the Czech Republic were asked to look at 80 pictures of people at the age between 19 and 26 years old, 40 men and 40 women. Then they were supposed to rate people's trustworthiness on a 10 point scale. Those with brown eyes were ranked higher than the ones with blue eyes. Even though the correlation appears as obvious, it's not that simple. It was facial morphology linked to brown eyes that was more important than the eye color itself.
Well, let's be honest – truly black eyes don't exist. They might be so dark that they look as if they were black, but the fact is that they're just very very dark, never truly black. The researches show that people with darker eyes are considered to be more agreeable. Some other studies show that people with black eyes are also better at sports that involve hitting targets and drink less alcohol than people with paler eyes.
Hazel eyes often switch color from brown to green. People with this eyes color often have a multicolored iris. It's said that hazel eyes change the color with the mood. The truth is that they simply look different depending on the light and the surroundings, so, for example, the clothes one's wearing. Hazel eyes are still a little bit of a mystery, even if it comes to defining the color. Actually, it's a blend of various colors rather than a true color itself, which doesn't make it any less appealing. Just think of some celebrities that have hazel eyes: David Beckham, Penélope Cruz, Jessica Alba, Ben Affleck. They're all good looking and their unique eyes make them even more attractive.

Did you know that 74% of hazel eyes appear to have a brown ring around the pupil? They're still a lot less popular than brown ones and that's why the people with that eye color are told to be unique and mysterious. Due to a moderate amount of melanin, their personalities are considered balanced. Slightly ironically, according to Dr. Matthew Leach of the University of South Australia, the color might be caused by liver imbalance, which could make people with hazel eyes to be more vulnerable to digestive problems.!
Amber eyes are one of the rarest eye colors occurring among humans. Some researches indicate that only 0.01% of the human population have amber eyes. That eye color is, however, quite common among animals, such as cats, owls, eagles or wolves. That's why amber eyes are sometimes called “wolf eyes”. The color might be confused with hazel, but amber eyes are a solid gold hue. It doesn't contain other colors. The hue is caused by lipofuscin, a yellowish pigment of the iris.
As many things that are unique, amber eyes are considered to be alluring. Some people even believe that they're a sign of supernatural powers. The truth is much less magical – the color is just a result of a series of mutations. So, despite some beliefs in traditional societies, it has nothing to do with turning into wolves or mystical creatures. No joke!
Another very rare eye color is green. Although the world is lacking serious researches showing how many people have green eyes, for some reason, it is commonly quoted that it's 2% of the human population that are lucky to have that desired eye color.

It's difficult to say if it's true, but the fact itself that others think you're special just because you have green eyes is nice, right? Green eyes
