To correct myopia, is it necessary to move the image formed by the eye closer to or farther from the eyes lens system? Does this require a convergent or divergent lens? Does this corrective lens add to or subtract from the light-bending power of the eyes lens system? Is the curvature of this lens concave or convex?
