  • Patent number: 9557578
    Abstract: Methods for determining a progressive ophthalmic lens are described, the lens comprising a near and a far vision area, a main meridian separating the lens into a nasal and a temporal area. The method includes determining a first and a second surface of the lens, determining the second surface to provide, in combination with the first surface, vision correcting properties, and determining a spherical area on the first surface of the lens having a constant sphere value and including a far vision diopter measurement position. The far vision diopter measurement position and a near vision diopter measurement position have substantially the same mean sphere value. The method also includes determining the first surface to reduce the lens distortion by defining a toric area extending outside the spherical area on the first surface in at least one of the nasal and the temporal area, in which characteristics of the toric area are related to the lens astigmatism.

  • Patent number: 8814354
    Abstract: A process for designing an ophthalmic progressive eyeglass comprises providing an initial front surface and an initial back surface. Respective addition values of front and back surfaces of the eyeglass are varied based on said initial front and back surfaces using a surface derivation tool. These surface addition values are selected so that the eyeglass exhibits an eyeglass addition value which matches a wearer's prescription and a value for a design feature which matches a target value. Said target value may be used for customizing the ophthalmic progressive eyeglass. The process does not require point-to-point surface optimization.
