ABSTRACT:
A bifocal multiorder diffractive lens having a lens body with one or more first regions having a first multiorder diffractive structure providing near vision correction, and one or more second regions having a second multiorder diffractive structure providing distance vision correction, in which the lens defines an aperture divided between the first and second regions. The lens body may be provided by a single optical element or multiple optical elements. In other embodiments, a bifocal multiorder diffractive lens is provided by a single or multiple element lens body having a multiorder diffractive structure for distance vision correction and one or more refractive regions to add power for near vision correction, or a single or multiple element lens body shaped for refractive power for distance vision correction and a multiorder diffractive structure for add power for near vision correction. Multiorder diffractive structures may be optimized for photopic and scotopic vision.
