Hannah's eyes have the same range as her sister's, with the same focal power for her cornea (50 diopters) and for her variable lens (5 diopters), but hannah suffers from myopia. she cannot focus on any object that lies more than 0.8 meters from her eyes since they are slightly longer -- the cornea to retina distance is larger -- than her sister's eyes. considering this new far point, what is the diameter of hannah's eyes (in millimeters, to the nearest tenth of a millimeter) assuming anna's eye diameter was ideally, again, 20.0 mm? hint: the focal power of the cornea remains the same for hannah as for anna for focusing distant objects, but the farthest hannah can see (object distance) changes from infinity to 0.8 meters.
