The term 'Pigmented Layer' refers to the Uvea, which is a four-letter word. The Uvea is the middle layer of the eye and is composed of three parts: the choroid, ciliary body, and the iris. The choroid is a dark brown pigmented layer that contains blood vessels and melanin, which gives the eye its color. 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 is responsible for controlling the size of the pupil. Together, these three parts make up the Uvea, which is an important part of the eye and helps to protect it from damage.
