Accommodation for near vision requires:
1. flattening of the lens.
2. contraction of the ciliary muscles.
3. activation of the sympathetic nervous system.
4. increased rounding of the cornea.
5. dilation of the pupil.

Option 2.

Accommodation of near vision requires the contraction of ciliary muscles.

Explanation:

Accommodation is the ability of the eye to adjust it optics thereby focus clear image of the objects on retina at various distance. Accommodation of near vision requires contraction of ciliary muscles. The lens is responsible for accommodation. The lens focuses light rays on retina. The ciliary muscle contract and make the lens to change shape, there by causing objects to appear real or cause accommodation of near vision.
