The Iris
No, the choroid is not the pigmented layer of the eye. The pigmented layer is called the retina, specifically the pigmented epithelium layer of the retina. The choroid is a vascular layer located behind the retina that provides oxygen and nutrients to the retina.
The pigmented portion of the eye with a rounded opening through which light passes is the iris. The iris controls the size of the pupil, which regulates the amount of light entering the eye.
Retina
The radial and circular muscles of the iris.
The part of the eye that consists of a pigmented layer and a neural layer is the retina. The pigmented layer, known as the retinal pigment epithelium (RPE), helps absorb excess light and provides support to the photoreceptor cells. The neural layer contains the light-sensitive photoreceptors (rods and cones) and other neurons that process visual information before sending it to the brain. This structure plays a crucial role in vision.
The pigmented layer of the eye is called the uvea.

The choroid is the layer responsible for providing the pigmentation that forms most of the pigmented vascular tunic of the eye. It helps to absorb excess light and prevent reflection within the eye, contributing to visual acuity.
The pigmented tunic you are referring to is the choroid, which contains melanin that absorbs excess light and prevents it from scattering within the eye. This helps to improve visual acuity and reduce glare.
