    摘要: 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.

    摘要: The invention relates to a method for determining an aspherization layer for an ophthalmic lens for a wearer for whom a power and an astigmatism have been prescribed. The method can be used equally satisfactorily on a unifocal or a multifocal lens. The invention also extends to the method for determining an ophthalmic lens from an aspoherization layer obtained by the method. The invention improves the optical performance of lenses obtained from semi-finished lenses in which the complex surface is unknown.
