A nearsighted person cannot see objects beyond 80 cm from his eyes. Which one of the following combinations represents the correct focal length and the refractive power of the contact lenses that will enable him to see the distant objects clearly?
A) +80 cm, +1.3 diopters
B) -80 cm, +1.3 diopters
C) +80 cm, -1.3 diopters
D) -80 cm, -1.3 diopters
E) -1.3 cm, +1.3 diopters

Quizplus · Accepted Answer

A nearsighted person needs a lens with a negative focal length to correct their vision. The focal length (f) is -80 cm, and the refractive power (P) is calculated as P = 1/f (in meters), which gives -1.3 diopters.
