摘要： A lens system is presented having a diffractive optical power region. The diffractive optical power region has a plurality of concentric surface relief diffractive structures. A greater portion of light incident on a diffractive structure near the center point contributes to the optical power than light incident on a diffractive structure peripherally spaced therefrom.

摘要： Embodiments of the present invention relate to a multifocal lens having a mostly spherical power region and a progressive optical power region. Embodiments of the present invention provide for the proper alignment and positioning of each of these regions, the amount of optical power provided by each of the regions, the optical design of the progressive optical power region, and the size and shape of each of the regions. The combination of these design parameters allows for an optical design having less unwanted astigmatism and distortion as well as both a wider channel width and a shorter channel length compared to conventional PALs. Embodiments of the present invention may also provide a new, inventive far-intermediate distance zone and may further provide for increased vertical stability of vision within a zone of the lens.
摘要翻译：本发明的实施例涉及具有大致球面的功率区域和逐行光焦度区域的多焦点透镜。本发明的实施例提供了这些区域中的每一个的适当对准和定位，由每个区域提供的光功率的量，逐行光焦度区域的光学设计以及每个区域的尺寸和形状。与常规PAL相比，这些设计参数的组合允许具有较少有害像散和失真的光学设计以及更宽的通道宽度和更短的通道长度。本发明的实施例还可以提供新的本发明的远中间距离区域，并且还可以提供在透镜区域内增加的视觉垂直稳定性。
