Zusammenfassung:	A progressive power lens pair is provided with an object-side surface and an eyeball-side surface of the right-eye lens and an object-side surface and an eyeball-side surface of the left-eye lens which are set by ensuring that ADDR1−ADDR2 and ADDL1−ADDL2 take values different from each other, when prescribed additional power for the right-eye lens and prescribed additional power for the left-eye lens are equal to each other; and prescription information for the progressive power lens pair indicates: that spherical power SR at the right-eye lens and spherical power SL at the left-eye lens are different from each other, that astigmatic power CR at the right-eye lens and astigmatic power CL at the left-eye lens are different from each other, or that an astigmatism axis angle AxR corresponding to the right-eye lens and an astigmatism axis angle AxL corresponding to the left-eye lens are different from each other.
