Bifocal glasses are used to correct both nearsightedness and farsightedness at the same time. (Figure 1)
Part A: If the near points in the right and left eyes are 38.0 cm and 46.0 cm , respectively, and the far point is 210 cm for both eyes, what are the powers of the lens prescribed for the right eye? (Assume that the glasses are worn 3.00 cm from the eyes.)
Part B: What are the powers of the lens prescribed for the left eye?
