Become part of the blue eyes story

For most of prehistory, there was no variation in eye colour; everyone had brown eyes. And most of the world's population still does.

Around 10,000 years ago, almost certainly around the Baltic Sea, a variant in the eye colour of a single individual appeared; this was the first person to have blue eyes.

And all those who have blue eyes are descended from that person.

In only a few thousand years, the most common eye colour in Northern Europe flipped from brown to blue.

Participate in's eye colour research project

The most common eye colour in Britain and Ireland is blue.

But at, we want to find out more. Which regions have the highest number of blue eyed people? Are brown eyes more common in a particular nation?

This research on eye colour is on-going; you can add to the sum of knowledge by taking the Blue Eyes test.
