Final answer:
Hyperopia occurs when the lens of the eye is unable to converge the rays from a close object by the time they strike the retina. It is corrected with a converging lens to increase the optical power of the eye.
Step-by-step explanation:
Hyperopia occurs when the lens of the eye is unable to converge the rays from a close object by the time they strike the retina, resulting in blurry close vision. It can be caused by insufficient power in the lens or by the eye being too short. Hyperopia is corrected with a converging lens to increase the optical power of the eye.
