The sphere correction in Ally's left eye is $+3\mathrm{.}0,$ in her right eye it's $-1\mathrm{.}5.$ An object must be at least $18\mathrm{.}5$ centimeters from her left eye before she can see it in focus and at least $17\mathrm{.}8$ centimeters from her right eye before she can see it in focus.$$ One of her eyes has a larger amplitude of accommodation than the other; how many percent larger is it$?($for example, one could say something like "Ally's left eye has a $35\%$ larger amplitude of accommodation than her right eye"$)$
