Blue eyes have historically been a significant measure of attractiveness, and although they’re commonly found among actors and models, only 17% of the global population has them. For the majority of people, approximately 80% of the population, blue eyes have been attainable only with the aid of colored contact lenses or artificial iris implants. But that will soon change with the introduction of a new medical procedure, pioneered by California company Stroma Medical, that can turn brown eyes blue.
The laser procedure works by eliminating the melanin -, the pigment that also colors hair and skin – from the surface of the iris, which then allows light to enter and scatter in the stroma, the fibers seen in light-colored eyes. The effect is similar to Rayleigh scattering, in which wavelengths of sunlight hit much smaller molecules in the air and then scatter, which makes the atmosphere appear blue.
