My rx is as follows:\n\nOD: (sphere) -2.50, (cylinder) -1.00, (axis) 105\n\nOS: (sphere) -2.50, (cylinder) -1.25, (axis) 083\n\nMeasures my Pupilary distance and one day it was 65, the next was 64. Will this be a problem? (Ordered glasses online). Will 1mm make a difference? What is the "grace" amount for PD?\n\nThanks!
