    • An ophthalmic lens for providing a plurality of foci has an optic comprising an anterior surface, a posterior surface, and an optical axis. The optic has a first region and a second region. The first region has a refractive optical power and comprises a multifocal phase plate for forming a first focus and a second focus. The second region has a refractive optical power and comprises a monofocal phase plate for forming a third focus. The multifocal phase plate and the monofocal phase plate may be disposed on first and second base curvatures, respectively, that may have different radii of curvature. The ophthalmic lens may also have an intermediate phase plate located between the multifocal phase plate and the monofocal phase plate, the intermediate phase plate comprising a third plurality of echelettes disposed on a third base curvature having a third radius of curvature.
    • 用于提供多个焦点的眼科镜片具有包括前表面,后表面和光轴的光学元件。 光学元件具有第一区域和第二区域。 第一区域具有折射光焦度并且包括用于形成第一焦点和第二焦点的多焦点相位板。 第二区域具有折射光焦度并且包括用于形成第三焦点的单焦点相位板。 多焦点相位板和单焦点相位板可以分别设置在可以具有不同曲率半径的第一和第二基本曲率上。 眼用透镜还可以具有位于多焦点相位板和单焦点相位板之间的中间相位板,中间相位板包括设置在具有第三曲率半径的第三基底曲率上的第三多个小阶梯。
