The two structures that the choroid layer forms anteriorly within the eyeball are the **ciliary body** and the **iris**.

1. **Ciliary Body**: This structure is a muscular ring that is located just behind the iris. It is responsible for controlling the shape of the lens, allowing for focusing on objects at various distances. The ciliary body also contains the ciliary processes, which produce aqueous humor, the fluid that fills the anterior chamber of the eye.

2. **Iris**: The iris is the colored part of the eye and is located in front of the lens. It regulates the diameter of the pupil, thereby controlling the amount of light that enters the eye. The iris contains smooth muscle fibers that can constrict or dilate the pupil in response to light conditions.

These two structures play crucial roles in vision and help protect the internal components of the eye.
