Abstract

A method for adjusting spectacles in which a virtual fitting process of a parametric frame model of a spectacle frame on a 3D model of the head of a person, to whom the spectacles are to be fitted, is divided into two fitting procedures. In a first fitting procedure, the parametric frame model is adjusted to the 3D model of the head to meet specific fitting guidelines for the parametric frame model. Fitting guidelines of this nature may be specified by a frame manufacturer to comply with aesthetic criteria in the fitting. Anatomic fitting is then performed in the second fitting procedure.
