1. The problem statement, all variables and given/known data A nearsighted patient's far point is 0.717 m from her eyes. She is able to see distant objects in focus when wearing glasses with a refractive power of -1.45 diopters. What is the distance between her eyes and the glasses? di = 0.717m refractive power = -1.45 diopters 2. Relevant equations 1/do + 1/di = 1/f refractive = 1/f 3. The attempt at a solution I first tried to put the refractive power into the focal point using the equation my book gave us. -1.45 = 1/f f = 1/-1.45 Then I set up the equation as best as I could 1/do + 1/.717 = 1/-1.45 -> 1/do = 1/-1.45 - 1/.717 -> 1/do = -2.084 -> do = -.4798 This answer wasn't correct and I dont even know if I'm doing it right...please help!
