Lens
The eye lens is a transparent, flexible structure which, thanks to its varying degree of curvature (see ciliary muscle and zonular fibers), enables the process of accommodation (focusing) and thus sharp vision at different distances, especially at close range.

Change in the thickness of the lens of the eye by the ciliary muscles. This adjustment process increases the refractive power of the lens, allowing objects at different distances to be seen clearly.

Ciliary muscle
Through its activity via the zonular fibers, the ciliary muscle changes the curvature of the lens, thereby enabling accommodation (adjustment).

Zonules
The zonules are arranged in a radial pattern around the lens of the eye and connect it to the ciliary muscle.
