Page 9 - IP3A 004 Melanin Pigment

People with blue eyes do not obtain

this eye coloration as a result of

melanin pigment.

Instead, blue-eyed individuals have

very little melanin pigment in their

irises.

Rather, blue eyes result from the

same optical effect that causes the

sky to appear blue.

This phenomenon is called, Tyndall

scattering. Tyndall scattering results

when white light passes through a

medium where small particles are

suspended.
