A method of manufacturing a pair of progressive spectacle lenses having different prescriptions between right and left eyes, characterized by comprising steps of: determining a difference in a base curve between right and left of the progressive spectacle lenses which is associated to the different prescriptions; determining that usage of the progressive spectacle lenses is dynamic usage that dynamic recognition of depth in space is emphasized or static usage that static discrimination of an object in space is emphasized; making the base curve of right and left progressive spectacle lenses equal to each other, when being the dynamic usage, by making the base curve of a refracting surface on an object side of the progressive spectacle lens for a dominant eye correspond to the base curve corresponding to the prescription of a refracting surface on an object side of the progressive spectacle lens for a non-dominant eye, or when being the static usage, by making the base curve of the refracting surface on the object side of the progressive spectacle lens for the non-dominant eye correspond to the base curve corresponding to the prescription of the refracting surface on the object side of the spectacle lens for the dominant eye; and designing entire shapes of the right and left progressive spectacle lenses having the base curve equal to each other so as to satisfy the prescriptions. determining a difference in a base curve between right and left of the progressive spectacle lenses which is associated to the different prescriptions; determining that usage of the progressive spectacle lenses is dynamic usage that dynamic recognition of depth in space is emphasized or static usage that static discrimination of an object in space is emphasized; making the base curve of right and left progressive spectacle lenses equal to each other, when being the dynamic usage, by making the base curve of a refracting surface on an object side of the progressive spectacle lens for a dominant eye correspond to the base curve corresponding to the prescription of a refracting surface on an object side of the progressive spectacle lens for a non-dominant eye, or when being the static usage, by making the base curve of the refracting surface on the object side of the progressive spectacle lens for the non-dominant eye correspond to the base curve corresponding to the prescription of the refracting surface on the object side of the spectacle lens for the dominant eye; and when being the dynamic usage, by making the base curve of a refracting surface on an object side of the progressive spectacle lens for a dominant eye correspond to the base curve corresponding to the prescription of a refracting surface on an object side of the progressive spectacle lens for a non-dominant eye, or when being the static usage, by making the base curve of the refracting surface on the object side of the progressive spectacle lens for the non-dominant eye correspond to the base curve corresponding to the prescription of the refracting surface on the object side of the spectacle lens for the dominant eye; and designing entire shapes of the right and left progressive spectacle lenses having the base curve equal to each other so as to satisfy the prescriptions. <EOS>
