Models are chosen for their attractiveness, and it was found that, in Brazil, models with light eyes are in a significant excess compared to the levels found in the general population, while, in the UK, models with brown or intermediate eyes were in significant excess over their frequency in the general population. [50] Brown eyes are common in Europe, East Asia, Southeast Asia, Central Asia, South Asia, West Asia, Oceania, Africa and the Americas. In humans, brown eyes result from a relatively high concentration of melanin in the stroma of the iris, which causes light of both shorter and longer wavelengths to be absorbed.[48].
