$\huge \red {\mathbb {ANSWER}}$

• The image distance remains the same due to eye’s ability of accommodation the focal length of eye lens is adjusted.

• In order to see the nearer object the ciliary muscles contract due to which lens becomes thick and focal length is decreased to obtain a clear image at retina.
