PROGRESSIVE POWER LENS PAIR, METHOD FOR DESIGNING PROGRESSIVE POWER LENS PAIR, AND METHOD FOR MANUFACTURING PROGRESSIVE POWER LENS PAIR

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, with ADDR1 and ADDR2 respectively representing surface additional power at the object-side surface and surface additional power at the eyeball-side surface of the right-eye lens, and with ADDL1 and ADDL2 respectively representing surface additional power at the object-side surface and surface additional power at the eyeball-side surface of the left-eye lens, when prescribed additional power for the right-eye lens and prescribed additional power for the left-eye lens are equal to each other in the progressive power lens pair; 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.
