What Structure Changes the Shape of the Lens for Far

Question

What structure changes the shape of the lens for far and near vision?
A) aqueous humor
B) ciliary body
C) iris
D) extrinsic eye muscles
E) macula

Accepted Answer

The ciliary body is the structure that changes the shape of the lens for far and near vision through the process of accommodation. When we look at something far away, the ciliary body relaxes and the lens becomes thinner, allowing us to see clearly at a distance. When we look at something up close, the ciliary body contracts and the lens becomes thicker, allowing us to focus on nearby objects.
