Question

what do the ciliary muscles do to
focus the nearby and far objects​

Answer 1

Answer:

The ciliary muscles can contract and increase the curvature of the lens so that the lens thickens. The increased curvature of the lens allows the eye to focus on a close object. When the person then has to look at a faraway object, the muscles relax and the focus of the lens changes to an object further away.
