Abstract:

To provide a lens set, a lens design method and a lens manufacture method which suppress manufacturing costs and reduce flickers of images seen through lenses.

A lens set includes a first lens and a second lens, which are each a progressive power lens for spectacles including a far-vision part and a near-vision part with different power and have different additional power. The difference between vertical surface refractive power OVPf1 of the far-vision part and vertical surface refractive power OVPn1 of the near-vision part on the object-side surface of the first lens is equal to the difference between vertical surface refractive power OVPf2 of the far-vision part and vertical surface refractive power OVPn2 of the near-vision part on the object-side surface of the second lens.
