If we were on Jupiter, we would experience the Jovian sky in light pinks and reds. At one time, it was thought that if a person was born with blue eyes, it meant that their father had a dominant gene. Needless to say, we do not yet know enough about the human genome to determine why this is. To qualify as having blue green, one must have a hint of both colors in the iris.
In West Asia, a proportion of Israelis are of origin, among whom the trait is relatively elevated a study taken in 1911 found that 53. Credit: Pinterest This same phenomenon is why we experience the color of our sky as blue. A tiny fraction of blue eyes are caused by health conditions such as waardenburg syndrome and ocular albinism. These genes were responsible for 'depigmentation', and hence pale skin, in Europeans today. Personally, I think is it highly unlikely. Eyes can also change color according to one's emotion.

Ultimately, your eye color is a function of genetics and is determined by two factors: 1 the pigmentation of the and 2 the way light scatters around the iris itself. But if you look at other species on our planet, you will see eye colors come in rainbow, including yellows, reds and oranges.
In fact, almost any combinations of parent-child eye color can occur. But many historians believe that these eyes are inherited by these people from their ancient ancestors.

It's hard to predict when the mutation will appear again. In truth, your eye pigmentation has a small amount of brown in them. Just like blue eyes, green eyes are thought to be part of the human species as a result of genetic adaptations. Green eyes contain the yellowish pigment. Heterochromia This is where one eye is differently colored from another one, or one iris has different colors in it.
While this may sound like a fancy term, Rayleigh scattering is phenomenon that dictates how light bends and scatters. Classification systems have ranged from a basic light or dark description to detailed gradings employing photographic standards for comparison. Eye color chart Martin scale created a chart by the original. As per research, it is an ancient genetic mutation that has bestowed blue eyes in some people. . Credit: Pinterest Can your eyes change to blue? This might be one of the most important factors to explain the high proportion of blue eyes on the continent.

When vision changes after a blow to the eye, it is a warning sign that the injury may be more than a simple bruise. Though scientists used to believe that it was a relatively simple case of blue eyes being a recessive gene, and brown eyes being a dominant gene, it's now been found that eye color is determined by as many as 16 different genes. This is also interesting considering the fact that attractive people are generally more trustworthy and that blue-eyed people are generally considered more attractive than most. Some people believe that individuals with blue eyes are the result of an alien species depositing their genetic material into the human genome. Alexandria Genesis is kind of a myth.
