Focussing of an eye the objects lying at various distances
An
eye can focus the images of the distant objects as well as that of the
nearby objects on its retina by changing the focal length of its lens.
The focal length of the eye-lens is changed by the action of the ciliary
muscles. The ciliary muscles can change the thickness of the eye-lens
and hence its focal length changes the converging power of the eye-lens.
