WebJan 14, 2024 · Blue eyes don’t contain any blue pigment. Instead, they lack pigment found in other eye colors. Rayleigh scattering of light causes the blue color in the same way as it makes the sky appear blue. Eye color can change over time. Usually, color change occurs from hormonal changes or chemical reactions from medications. References WebOct 5, 2016 · Two things determine the appearance of emerald eyes: a low concentration of melanin, which makes them light amber, and the blue-ish effect of Rayleigh scattering in the iris.
