ABSTRACT:
A combined spectacle lens including a combination of a basic lens and an auxiliary lens, the basic lens formed with a progressive-power surface having a first power portion having a power for viewing an object at a predetermined distance, a second power portion having a power different from that in the first power portion, and a progressive portion in which the power is progressively changed from the first power portion to the second power portion on either one or both of refractive surfaces on an object side and an eyeball side, wherein a resultant power obtained by combining a basic lens power of the basic lens and an auxiliary lens power of the auxiliary lens is partly or entirely different from that of the basic lens power.
