The lens of the eye is bi-convex...sort of like an aspirin tablet.

It stretches out to an almost flat state when you want to focus on distant objects, then the ciliary muscles and the zonules relax when you focus up close, and the lens becomes thicker again, changing the refractive index of the lens.

It is that contracting and expanding that stops functioning as well as age creeps up and presbyopia sets in, causing a need for reading glasses.
