<human>:  How does the theory of accommodation work?
<bot>: Accommodation is a process by which the eye changes to adapt to the light conditions. The eye is able to change the shape of the lens to focus on objects at different distances. This is called accommodation. The lens of the eye is made up of a clear jelly-like substance called the lens capsule. The lens capsule is made up of two layers of cells, called the lens epithelium and the lens fiber cells. The lens epithelium is the outer layer of the lens capsule. The lens fiber cells are the inner layer of the lens capsule. The lens capsule is attached to the ciliary body, which is a muscle that moves the lens. The ciliary body is attached to the iris, which is a circular muscle that controls the size of the pupil. The pupil is the
