Blue eyes are uncommon globally , but not extremely rare: most estimates put them at about 8% to 10% of the world population. In the United States, they’re much more common, with one source citing about 27% of people.

Quick Scoop

Blue eyes are not the rarest eye color overall; some shades like gray, violet, or certain medical-condition-related eye colors are rarer. Their frequency also varies a lot by region, and they are much more common in parts of Northern Europe than in most of the world.

Why they seem rare

Blue eyes stand out because many large-population regions have mostly brown eyes, so blue eyes feel unusual in everyday life even when they’re not globally scarce. The color comes from low iris melanin and light scattering, not a blue pigment.

Simple takeaway

If you mean worldwide, blue eyes are fairly rare but not super rare. If you mean in some countries, they can be quite common.
