Winner of three awards including the John C. Wister Medal. 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). [21] Classification systems have ranged from a basic light or dark description to detailed gradings employing photographic standards for comparison. A study compared the frequency of eye color in commercial advertising models in Brazil and the UK; these countries were chosen because they have inverted frequencies of eye-coloration, with Brazil having an excess of brown and the UK an excess of light-colored eyes.

[35] Eiberg and colleagues suggested in a study published in Human Genetics that a mutation in the 86th intron of the HERC2 gene, which is hypothesized to interact with the OCA2 gene promoter, reduced expression of OCA2 with subsequent reduction in melanin production. Occasionally, heterochromia can be a sign of a serious medical condition. Plant in the Fall
