In addition to having significantly less melanin in their iris than people with brown eyes, hazel eyes or green eyes, blue-eyed individuals don't have very much variation in the part of their DNA responsible for melanin production. Occasionally, heterochromia can be a sign of a serious medical condition. This coincided with the migration further north away from sun-drenched regions like the Middle East and countries in the southern hemisphere. Blue eyes as a risk factor for type 1 diabetes, Eye color as a risk factor for acquired sensorineural hearing loss: A review, A global view of the OCA2-HERC2 region and pigmentation.

Bilirubin thus accumulates in the blood and makes the sclera and skin yellow.

Studies on Caucasian twins, both fraternal and identical, have shown that eye color over time can be subject to change, and major demelanization of the iris may also be genetically determined. [13][14] These genes are sought by studying small changes in the genes themselves and in neighboring genes, called single-nucleotide polymorphisms or SNPs. Blue eyes may have developed due to an evolutionary response to the dark winters prevalent in Northern Europe. "Why Edinburgh residents are likely to be blue-eyed", "Genetic determinants of hair, eye and skin pigmentation in Europeans", "Eye Color Percentage for Across the Globe", "Is there any difference in the photobiological properties of melanins isolated from human blue and brown eyes?

One possible explanation for the difference in the appearance of gray and blue eyes is that gray eyes have larger deposits of collagen in the stroma, so that the light that is reflected from the epithelium undergoes Mie scattering (which is not strongly frequency-dependent) rather than Rayleigh scattering (in which shorter wavelengths of light are scattered more). Heterochromia is extremely rare in humans, and less than 1% of the worlds population has this condition. Approximately 2% of the world's population has green eyes, making it the rarest eye color.
