Yup, but it's definitely got something to do with cold weather, same as pale skin. 99% of Estonia has blue eyes, 75% of Germany etc. etc. But seeing a shortage of melanin causing light to follow a rayleigh scattering path as a mutation is wrong. There's nothing mutant about blue eyes apart from our eyes being a lot more light sensitive due to the lack of the dark melanin pigmentation.
