7 Amazing Blue Eyes Facts You Can't Miss

Are Blue Eyes Really Blue?

Blue eyes don’t contain blue pigment, so it’s fair to say they aren’t really blue. They simply appear blue because the lack of melanin causes light to split into a color spectrum. This effect is known as Rayleigh scattering.

There is no actual blue pigment for eyes. People with brown eyes have them because melanin is a brown pigment.  The result of this scattering of light is blue light hitting the top of the iris. This gives the eyes their blue appearance.
