Abstract:
A diffractive multi-focal ophthalmic lens includes a novel structure and manufacturing method in which improvement in optical characteristics such as halo reduction is obtained. A diffractive multi-focal ophthalmic lens in which a plurality of focal points are set by a diffraction grating including a blaze shaped phase function in which a plurality of zone sequences are overlapped, wherein adopted is a structure expressed by a phase function in which an inclination of a blaze of a specific adjustment zone in a standard profile is reversed.

Claim (Index 8):
The diffractive multi-focal ophthalmic lens according to  claim 1 , wherein in a diffraction grating region in which the diffraction grating is provided, a total number of the adjustment zone is less than \u00bd a total number of the zones in the diffraction grating region.
