The ability of the human eye to adjust itself such that it can see objects which are nearby and faraway is called Accommodation.
It primarily involves the lens and ciliary muscles.
The ciliary muscles are capable of modifying the curvature of the lens and thereby affecting the focal length of the lens.
When viewing objects which are nearby, the ciliary muscles contract, the lens becomes thicker. It is squeezed into a more convex shape and the focal length decreases (curvature increases). The images again falls on the retina. Note that here the eye is 'accommodating' by taking a thicker shape so that the image falls on the retina
