For the correction of myopic defects in the human eye we require A. a convex lens B. a concave lens C. a combination of concave and convex lenses D. a prism E. a concave mirror.
ANSWER: Option B
EXPLANATION:
Correction of nearsightedness requires a diverging lens that compensates for the overconvergence by the eye. The diverging lens produces an image closer to the eye than the object, so that the nearsighted person can see it clearly. The person is suffering from an eye defect called myopia. In this defect, the image is formed in front of the retina. Hence, a concave lens is used to correct this defect of vision.
