For people who came for the answer, it's : "The lenses have different curvatures" (I don't have an explanation and I guessed but I wrote this since at the time of my writing no prior answers had been here. So someone who gave up now atleast knows the answer.)

I think it's because our eyes are not identical in focal power. So you need slight correction in one more than the other and the corrective lenses will have different focal lengths to account for the correction hence different curvature for each lens.
