Hint:The ciliary muscle is an intrinsic eye muscle that forms a ring of smooth muscle in the middle layer of the eye that is the vascular muscle. It regulates the flow of aqueous humour into Schlemm's canal and monitors accommodation for viewing objects at different distances.
Complete answer:
(a) The ciliary muscles contract as we look at things close to our eyes. The curvature of the eye lens is increased as a result of this. The eye lens thickens as a result. As a result, the focal length of the eye lens shortens. As a result, we can clearly see surrounding artefacts.Hence we can say that eye-lens become thicker when the eye is focused on a near object.
(b) When we look at a faraway object, the ciliary muscles relax, and the lens thins. As a result, the focal length increases. This allows us to clearly see distant artefacts.Hence we can say that eye-lens become thinner when the eye is focused on a distant object.
Note:Remember that eye-lens become thicker when the eye is focused on a near object and eye-lens become thinner when the eye is focused on a distant object. The focal length of an optical system is the opposite of the system's optical power; it measures how strongly the system converges or diverges light.
