    • A design family of contact lenses includes a central area utilized for distance vision, surrounded by multiple alternating annuli of near and distance optical powers, surrounded by a peripheral distance zone. The design can also be used in intraocular lenses (IOL). The distance optical power is constant across the design family of lenses, but the near optical power increases as a subject's presbyopia increases. The design family of contact lenses can be fitted to a patient in a standard fashion by fitting both eyes to the best distance visual acuity (VA), and obtaining near acuity from the near annuli. A modified monovision method fits the patient's dominant eye with a contact lens as described having the full prescription distance power and fitting the nondominant eye with a contact lens as described having a distance optical power between the full prescription distance optical power and the near optical power. Specifically, the nondominant eye is fitted with a contact lens as described but having a distance power between 50% and 100% of the range between the prescription near and distance optical powers, biased towards the distance optical power.
    • 隐形眼镜的设计系列包括用于远距离视觉的中心区域,被围绕由周边距离区域包围的近距离和远距离光功率的多个交替的环形环绕。 该设计也可用于眼内透镜(IOL)。 透镜设计系列的距离光功率是恒定的,但随着受试者的老视眼增加,近光功率增加。 隐形眼镜的设计系列可以通过将两只眼睛适配到最佳距离视力(VA),并从近环获得近视力,以标准方式安装到患者身上。 改进的单视方法适合患者的主眼,所述隐形眼镜具有如所述具有完全处方距离力的隐形眼镜,并且使非隐性眼睛与如在所述处方距离光功率和近光功率之间具有距离光焦度所述的隐形眼镜相适配。 具体而言,非优势眼配备有如所述的隐形眼镜,但距离光学功率偏置在处方近距离和距离光焦度之间的距离的50%至100%之间。
