Iris
The iris and the ciliary body
The colored membrane attached to the ciliary body is the iris. The iris is located in front of the lens of the eye and is responsible for controlling the size of the pupil, which regulates the amount of light entering the eye.
Lens does not belong, as it is not part of the structures involved in the formation or regulation of the aqueous humor within the eye like the ciliary body, iris, and suspensory ligaments.
choroid
Choroid Ciliary body Iris
The uveal tract is composed of the iris, ciliary body, and choroid. The iris is the colored part of the eye that regulates the amount of light entering the eye. The ciliary body produces aqueous humor, which nourishes the eye and maintains its shape. The choroid is a vascular layer that provides oxygen and nutrients to the retina.
iris and ciliary muscles
The ciliary body is a specialized structure which anchors the iris with the choroid. It makes aqueous humor and anchors the lens via the zonules, through which it modulates lens changes.The ciliary body is a specialized structure which anchors the iris with the choroid.

The two involuntary muscles that make up the front part of the eye are the iris and the ciliary body. The iris controls the size of the pupil, regulating the amount of light entering the eye. The ciliary body adjusts the shape of the lens, enabling the eye to focus on near or distant objects.
