A certain child's near point is 11.0 cm; her far point (with eyes relaxed) is 135 cm. Each eye lens is 2.00 cm from the retina. (a) Between what limits does the power of this lens-cornea combination vary?
(b) Calculate the power of the eyeglass lens the child should use for relaxed distance vision. Is the lens converging or diverging?
