It’s pretty well-known that brown eyes are the most common eye color in the world. But it’s not just common — it’s overwhelmingly common, to the tune of 79 percent of the world’s population, according to World Atlas. The next most common eye color in the world is blue, which clocks in at 8-10 percent, mostly present in European countries. Hazel eyes clock in at 5 percent, as do amber eyes, followed by green eyes at a paltry 2 percent. And each of the following colors are less than one percent of the world’s population: gray eyes, red/violet eyes (in people with severe forms of albinism), and heterochromia (different colored eyes).
