摘要:
In certain embodiments, an ophthalmic lens comprises an optic. The optic has an optical axis and surfaces comprising an anterior surface and a posterior surface. At least one of the surfaces has an inner refractive region and a refractive-diffractive structure disposed outwardly from the inner refractive region in a direction away from the optical axis. The inner refractive region is adapted to contribute refractively to a distance focus optical power. The refractive-diffractive structure comprises one or more diffractive regions and one or more refractive regions. A diffractive region is adapted to contribute diffractively to a multi-zone optical power, and a refractive region is adapted to contribute refractively to the distance focus optical power.
