    • An ophthalmic lens includes an optical zone having a center and a spaced-apart periphery. The optical zone has a first corrective power range in a first region and a second corrective power range in an annular region surrounding the first optical zone. The second corrective power is corrective of spherical aberration of an eye. The optical zone has a power profile that gradually changes from the first corrective power to the second corrective power. A central progressive zone that provides intermediate vision correction may be applied to a central region of the lens. The progressive zone has a diameter that is less than or equal to the diameter of an aperture of a pupil when subjected to bright light.
    • 眼科镜片包括具有中心和间隔开的周边的光学区域。 所述光学区域在围绕所述第一光学区域的环形区域中具有第一区域中的第一校正功率范围和第二校正功率范围。 第二个校正功率是矫正眼球的球面像差。 光学区具有从第一校正功率逐渐变化到第二校正功率的功率曲线。 提供中间视力矫正的中央渐进区域可以应用于镜片的中心区域。 进行区域的直径小于或等于受到明亮光线时光瞳孔径的直径。

    • The present invention is related to a contact lens for correcting severe spherical aberration. The contact lens of the invention comprises an anterior surface having a first optical zone and an opposite posterior surface having a second optical zone. The first optical zone is defined by a mathematical function including a conic term and at least one 4th or higher order mathematic term. The first optical zone, in combination with the second optical zone, provides a power profile in which the optical power of the lens decreases outwardly from the optical axis to the outer periphery such that the optical power at a 6 mm diameter is from about 1 to 5 diopters smaller than a manifest refractive power for an eye. The present invention also provides a series of contact lenses and a method for making contact lenses of the invention.
    • 本发明涉及一种用于校正严重球面像差的隐形眼镜。 本发明的隐形眼镜包括具有第一光学区域的前表面和具有第二光学区域的相对的后表面。 第一光学区域由包括圆锥项和至少一个第四或更高阶数学项的数学函数限定。 第一光学区域与第二光学区域组合提供了功率曲线,其中透镜的光焦度从光轴向外减小到外周边,使得直径为6mm的光焦度为约1至 5屈光度小于眼睛明显的屈光力。 本发明还提供一系列隐形眼镜和制造本发明隐形眼镜的方法。
