Final answer:
Nearsightedness is usually corrected with a diverging lens or diverging eyeglass lens, which compensates for the overconvergence by the eye and produces an image closer to the eye than the object.
Step-by-step explanation:
Nearsightedness is usually corrected with diverging lens or diverging eyeglass lens. A diverging lens compensates for the overconvergence by the eye and produces an image closer to the eye than the object, allowing a nearsighted person to see it clearly. This lens helps reduce the optical power of an eye that is too powerful.
