Blue Eyes in Africa is seriously rare; nevertheless there are black people with the trait. I know as a ‘superstitious’ people, many weird theories have possibly gone into the divulging of this rarity. Emphatically speaking, beyond photoshop and contact lenses, Africans do have blue eyes but it is not as common as the brown eyes which is endemic to the black race.
So when you see a black African who is not even racially mixed with the blue eyes, spare your reservations because contrary to whatever strange thought that comes to your mind, they are normal human beings with a rare genetic mutation or just a health condition.
Blue eyes is not only a Caucasian trait, it goes beyond race and ethnicity; besides, black people are most prone to genetic diversity. Here is everything you need to know about blue-eyed Africans:
1. Scientific discovery has proven that beneath all brown eyes lies the blue colored eyes; both are separated by a very thin layer
2. Waardenburg Syndrome is a genetic optical condition that makes the eyes blue – affects either one or both; and can also affect hearing loss. It could also be a sign of ocular albinism.
3. It could be a sign of melanin deficiency – Just as melanin helps to protect the skin from ultraviolet rays of the sun, it also protects visual cells at the back of the eye.
According to Stanford University’s Museum of Innovation:
“Eye color is the result of variations in the amount of melanin, a pigment found in the front part of the iris of the eye. The total lack of this pigment results in blue eyes, some pigment gives green, and lots of pigment gives brown eyes. So light brown eyes just have a bit less melanin than darker brown eyes. All of the different shades of eye color happen the same way. Blue-green eyes have an amount of melanin between green and blue, hazel eyes have an amount of pigment between green and brown, etc.”

4. Medically Speaking – there is no recorded advantage to having blue eyes though in present day style, it can be termed fashionable. Thus people adorn their “healthier” eye colors with blue contact lenses. Somehow uncommon traits have a way of being attractive – dimple is another example.
5. Some Other Eye Diseases – such as uveal melanoma (the most common eye cancer in adults) and Age-related Macular Degeneration, are more common in people with lighter eye-colors.
6. It takes (even brown-eyed) parents with the gene(recessive or dominant) to have a blue-eyed child
“The mutation for blue eyes, a change in the HERC2 gene, is thought to have first appeared around the Black Sea 10,000 years ago and then gradually moved west. Because the gene is recessive, blue-eyed people must have two copies, one from each parent.” Forbes
7. Since the blue eyes reveal a pigmentation problem, people with blue eyes often have vitiligo – a skin condition where the skin looses pigmentation, thereby giving blotches to some parts of the body. The pigmentation problem can also extend to the hair and the mouth (Mayo Clinic).
8. It is believed that all blue-eyed persons share a single ancestor who lived between 6,000 and 10,000 years ago (Hans Eiberg, University of Copenhagen).
