Question

A near-sighted person wears eyeglasses with a power of -5.5D for distant vision. If the doctor prescribes him a correction of 1.5D in the near vision section of a bifocal lens:

a) The near vision correction will be +1.5D
b) The near vision correction will be -1.5D
c) The distant vision correction will be -5.5D
d) The distant vision correction will be +5.5D

Answer 1

A near-sighted person wears eyeglasses with a power of -5.5D for distant vision. The prescription for the near vision section of the bifocal lens is +1.5D.

Step-by-step explanation:

The near vision correction for a near-sighted person wearing eyeglasses is given as +1.5D. Since the person is already near-sighted, their distant vision correction with the eyeglasses is -5.5D. The prescription for the near vision section of the bifocal lens helps the person see clearly at close distances, and it is given as +1.5D. Therefore, the correct option is (a) The near vision correction will be +1.5D.
