How is the lens of a camera similar to the lens of the eyes?

camera lens is like an eye.

lens can focus an object from far to near by its accommodative tone. Ciliary muscles contract so zonule of fibers with which lens is attached relaxe and move the anterior curvature forwad hence increase the power of eye as well.vice versa is done while focusing from near to far.

same is done by lens in camera by moving it forward or backward so for increasing or decreasing its power.
