One of the most fascinating Tyndall Effect examples is the blue colored iris. The translucent layer over the iris causes the scattering of the blue light making the eyes look blue. In general, this layer is opaque because of high melanin content. But in blue eyes, this layer over the iris is translucent which helps in giving it a blue color.
Mostly Tyndall Effect is used in laboratories for determining the size of the aerosols.
