When someone wants to enhance their vision, they may try contact lenses or seek out LASIK eye surgery ๐ But what if they want to change the colourr of their eyes? People have long been fascinated with eye colourr; after all, eyes come in a wide range of shades ๐ Exactly what colourr are your eyes? Hazel-ish? Blue-gray-green? Blue brown spots? Do you see green with gray spots? Most of us are taught in high school biology that two blue-eyed parents are guaranteed to have blue-eyed kids, but itโs not that straightforward. It is difficult to determine the genetics behind eye colour. Blue eyes do not all have the same genetic makeup. Eye colour is determined by many gene combinations. See below for an example: [1]
Only about 2 percent of the worldโs population has green eyes. A genetic mutation called green eyes produces low amounts of melanin but higher than blue eyes. The green pigment is the same as in blue eyes. Because there is no melanin within the iris, light scatters more, making the eyes look green. There are changes light make lighter eyes look like they are changing colors like a chameleon. Ireland, Scotland and Northern Europe are home to the largest number of people with green eyes. All races can have green eyes, but not just Caucasian or Africans, Asians, Pacific Islanders and Native Americans of the Americas. Ronel Okeefe was kind enough to let us know. [2]
