My farsighted eye can read the book as close as 42 cm with a prescription of +0.95 D. [Answer in 3 significant figures] a) What is the new prescription if I want to read the book at a distance of 25 cm?

b) What magnitude of radius of curvature is required for this new prescription if the base curve of the contact lens is 7.8 mm? Base curve of a contact lens is the curvature of the back surface of the lens (i.e. closest to the eyeball). The index of refraction of the contact lens is 1.44.
