Answer

Brief Explanations:

In nearsightedness (myopia), the focal point of the eye is in front of the retina. A concave lens is used to diverge the incoming light rays, which extends the focal point so that it falls on the retina, correcting the vision. Convex lenses are used for farsightedness.

Answer:

B. A concave lens is used to extend the focal point slightly.
