A physics professor requires reading glasses with +1.6 D power toread a book held 39.1 cm away with a relaxed eye. Assume theglasses are 2.5 cm in front of his eyes.
(a) What is his uncorrected far point?
(b) What refractive power lenses should he use for distancevision?
(c) His uncorrected near point is 1.00 m. What should be therefractive powers of the two lenses in his bifocals be to give himclear vision from 25.0 cm to infinity?
