When the ciliary muscles are relaxed, the eye lens becomes thin and the focal length increases which enables us to see distant objects clearly.
When the ciliary muscles contract, the eye lens becomes thick and focal length decreases which enables us to see nearby objects clearly.
In simple words
Ciliary muscles relax-lens thin-focal length increases-distant objects
Ciliary muscles contract-lens thick-focal length decreases-nearby objects
