Answer
Ciliary muscles
Explanation
Ciliary muscles contract or relax to change the shape of the lens for focusing on objects at different distances.
Common mistake
Misunderstanding Accommodation
Students often confuse the processes of accommodation for near and distant objects, incorrectly stating that the lens becomes thinner for near objects.
Remember that for near objects, ciliary muscles contract, suspensory ligaments loosen, and the lens becomes thicker to focus the light correctly on the retina.
