An optometrist needs to prescribe corrective lenses for a person whose near point is q- 64.6 cm. If the patient is to see objects clearly at a distance of p - 25.0 cm, calculate the following. (Neglect the distance from the lens to the eye.) (a) focal length (in cm) of the appropriate corrective lens Om (b) power (in diopters) of the appropriate corrective lens diopters
