During close vision, what actions must the eye take to bring an object into focus?

relax the ciliary body dilate the pupil contract the ciliary body change the curvature of the cornea

Answer:contract the ciliary body change the curvature of the cornea

Explanation:the ability of the human eye to focus on near and distant objects is called accommodation. this is affected by an alteration of focal length of the eye lens which is controlled by the ciliary muscles.

In viewing close objects, the ciliary muscles contracts and reduces the size of the lens to become more spherical. the focal length also shortens. the inability of the eyes to focus on near object is called long sightedness. a converging lens is used to correct the defect.
