METHOD FOR CREATING A SETTING FOR TRIMMING AN OPHTHALMIC LENS
The method involves calculating differences between a two-dimensional projection of a longitudinal profile of rims (11) of a spectacle frame e.g. full-rim spectacle frame (10), and a set of predetermined geometrical figures on the projection. A target geometrical figure that is closest to the longit...

Summary: | The method involves calculating differences between a two-dimensional projection of a longitudinal profile of rims (11) of a spectacle frame e.g. full-rim spectacle frame (10), and a set of predetermined geometrical figures on the projection. A target geometrical figure that is closest to the longitudinal profile is selected among a set of target geometrical figures associated to trimming parameters according to the differences. A trimming setpoint is calculated according to the shape of the longitudinal profile and the trimming parameter of the selected target geometrical figure. An independent claim is also included for a method for configuring a device to prepare an ophthalmic lens. |
