A person's prescription for her new bifocal glasses calls for a refractive power of -0.400 diopters in the distance-vision part, and a power of 1.85 diopters in the close-vision part.What are the near and far points of this person's uncorrected vision? Assume the glasses are 2.00 cmfrom the person's eyes, and that the person's near-point distance is 25.0 cm when wearing the glasses.
