A certain child’s near point is 10.0 cm ; her far point (with eyes relaxed ) is 125 cm . Each eye lens is 2.00 cm from the retina .

a) Between what limits , measured in diopters, does the power of this lens-cornea combination vary ?

b) Calculate the power of the eyeglass lens the child use for relaxed distance vision . Is the lens converging or diverging ?
