Answer 1

To restore clear vision in persons whose size of the eye ball has reduced, he/she is suggested to use suitable converging lens.

Explanation:

When the size of the eyeball is reduced, the image tends to form behind the retina, causing hypermetropia (long-sightedness). A converging (convex) lens helps by converging light rays before they enter the eye, so the image is formed on the retina. Thus, clear vision is restored using a converging lens.
