The term 'Pigmented Eye Layer' refers to the Uvea, which is a layer of the eye that contains melanin and other pigments. It is composed of three parts: the choroid, ciliary body, and iris. The choroid is the layer closest to the retina and is responsible for supplying blood to the eye. The ciliary body is responsible for controlling the shape of the lens and the amount of light entering the eye. The iris is the colored part of the eye and controls the size of the pupil. Together, these three parts of the uvea provide protection and color to the eye.
