The term 'Pigmented Eye Part' refers to two distinct parts of the eye: the IRIS and the uvea. The IRIS is the colored part of the eye that surrounds the pupil and controls the amount of light entering the eye. The uvea is the middle layer of the eye, which contains melanin, a pigment that gives the eye its color. Together, these two parts of the eye are responsible for the color of the eye and the amount of light that enters it.
