METHOD OF MANUFACTURING PROGRESSIVE MULTIFOCAL LENS

摘要

A method of manufacturing a progressive multifocal lens (70) having a far use portion (72) and a near use portion (73) having mutually different refractive powers and a progressive surface (71) constituting a progressive portion (74) having a refracting power changing progressively between the far and near use portions (72 and 73) includes a lens design step (2) for designing a progressive surface reflecting customization information (1) for individual users including at least either one of the information about the eyes of individual users and the information about the user's lives, and deriving machining data of a progressive multifocal lens having a customized progressive surface. This production method can provide an inexpensive eyeglass lens most suitable for the user, from which the step of machining lenses in a semi-finished state and keeping them in stock can be eliminated.
