METHOD FOR DETERMINING AN ASPHERIZATION LAYER FOR AN OPHTHALMIC LENS |
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.
