We human beings are the most alluring and amazing creation of this World. It is said that the eyes are the mirror of the heart; a reflection of our inner self, emotion with innumerable poets, writes, and artists praising this unique quality. The first look of every person is eyes, eyes are deeply fascinating. I think it won’t become more interesting and perhaps more frightening, and more curious if they weren’t colored.
Why these eyes are of a different color? The eyes color is determined by the amount of Melanin, a pigment found in the front part of the iris of the eye. The more amount of pigment melanin the darker the iris will be i.e. Dark Brown. Green, Blue, Gray eyes are due to less amount of pigment melanin inside the iris. By far, the most common eye color is Brown in this world, with over 55% of the population fall under this category.
Depending upon where we were a person is born, eye color varies wildly. For instance, almost all the people of African and Asian ancestry have brown eyes. It is believed up to 10,000 years ago, all human had brown eyes only. Then the mutation turned off the pigmentation on the front of the iris. The next common eye colors are Blue, Gray, and Green in this order.
Hazel eyes are similar to brown eyes, the distinction being these are lighter. A defining trait is their multicolored appearance that can vary from copper to green depending upon the lighting. Hazel eyes have a high concentration of melanin around the iris border i.e. up to 5-8% of the world’s population. Only 2% of the world’s Population has Green eyes which is very rare. There are ‘Amber eyes’ or ‘wolf eyes’ which are rarer than Green eyes. They have a strong yellowish, golden, or russet and coppery tint colors.
There is no clear information how amber eyes form but supposed that it is due to the increased presence of a pigment ‘Lipochrome’ also known as Pheomelanin.
