Imagine this, when someone is born you may see a resemblance to their parents, but then you notice that the eyes of the child are different than the parent’s eyes. According to https://www.allaboutvision.com/conditions/eye-color-chart.htm
This is very normal to happen, since genes are not in charge of what the color of the eye is going to be, instead the genes decide how much melanin is going to be int he iris ( the part of your eye the contains the color) Melanin is a dark brown or black pigment that determines what your hair, skin and the color of the iris. But you may ask yourself “if melanin is dark how can people have lighter eyes like blue or grey?” how I said the genes are responsible for how much melanin to put in the eye, so the much more melanin the darker the eye will be creating a dark the color brown in the eye. While the less melanin in the iris the lighter the eye color, creating the Blue and grey eye colors. Albinism is a rare disorder that makes the skin and hair to contain no melanin. this means that there is no melanin in the iris so the eyes of an albino person will be red since the thing that makes it red is not melanin it will be the blood flowing through the blood vessels that are visible explains https://www.edow.com/general-eye-care/eyecolo.
The main eye colors in the world are Brown, Blue, Green, hazel, amber, and grey. Some People with albinism have red eyes (due to the extreme lack of melanin the blood vessels are visible) says https://www.edow.com/general. Brown eyes are the most common eye color according to https://www.edow.combrown is approximately 55%-79% of the world, this suggests that more than half of the people on earth have brown eyes, think about it there are about 7 billion people on earth! Besides being the most common, the brown eye has more melanin, some people have such dark brown eyes that it no longer looks like brown but black because of the high levels of melanin in the iris.
The blue eye has little pigment. And 5% of the people on earth possess a blue eye color. Did you know Scientists say people with blue eyes are related? Many years ago a mutation led to the blue eye and to a gene that prevents the production of melanin in the eye, now that racial groups intermarrying people with blue eyes are becoming rarer every day. The grey eye is often mixed up with the blue eye and it appears to change color depending on the lighting, clothes, and mood. About 1% of the people have a grey eye in the world. Scientist says that 5% of the people have hazel eyes. The hazel eye consists of mixtures between blue, green, and brown and along with grey the iris also appears to change color. green eyes are the least common color about 2% of the people have, but it is most common in Europe and It is often confused with hazel, the green eye has a black ring around it, contrary to the hazel. That is all I have for you today, now go and stare at your beautiful eyes in a mirror now that you know more about them!
