Single correct option
A person can see nearby objects clearly but cannot see distant objects clearly. The defect and the lens used to correct it are
- A. myopia and convex lens
- B. hypermetropia and concave lens
- C. hypermetropia and convex lens
- D. myopia and concave lens
Show answer and solution
Answer: (D) myopia and concave lens
In myopia the eyeball is too long or the lens too converging, so the image of a distant object forms in front of the retina. A concave (diverging) lens reduces the converging power and shifts the image back on to the retina. Hypermetropia, the opposite defect, is corrected by a convex lens.
