摘要:
#$%^&*AU2019271990A120191219.pdf#####ABSTRACT A multifocal ophthalmic lens includes an ophthalmic lens having an anterior surface and a posterior surface and a diffractive element disposed on at least one of the anterior surface and the posterior surface. The diffractive element includes a plurality of annular diffractive steps and four consecutive diffractive orders. The ophthalmic lens produces a near focus, an intermediate focus, and a distance focus each corresponding to a different one of the four consecutive diffractive orders. The plurality of annular diffractive steps of the diffractive element are configured such that one of the four diffractive orders is suppressed and at least a portion of the energy associated with that suppressed diffractive order is redistributed to one of the near focus, the intermediate focus, and the distance focus.
