    • 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。

    • An ophthalmic lens provides a cumulative ratio of distance to near focal length that is predominantly distance correction under high illumination, nearly evenly divided under moderate illumination, and favoring again distance vision correction under low level illumination. The lens is specifically adjusted to match the patient's pupil size as a function of illumination level, in the preferred embodiment by applying pupil size parameters as a function of age. This lens has the properties of matching both the distribution of near and distance focal vision correction to the type of human activity typically undertaken in various illumination conditions, as well as matching particular lens dimensions to suit the size of the pupil as a function of illumination intensity.
    • 眼科镜片提供距离近近焦距的累积比例,主要是在高照度下的距离校正,几乎在中度照度下均匀分布,并有利于在低水平照明下再次进行距离视力矫正。 在优选实施例中,通过应用作为年龄的函数的瞳孔尺寸参数,镜片被特别地调节以匹配患者的瞳孔尺寸作为照明水平的函数。 该透镜具有将近距离和距离焦点视觉校正的分布与通常在各种照明条件下进行的人类活动的类型匹配的特性,以及匹配特定透镜尺寸以适合作为照明强度的函数的瞳孔尺寸 。
