METHOD OF PREPARING AN OPHTHALMIC LENS TO BE FLUSH WITH A SURROUND OF AN EYEGLASS FRAME

A method of preparing an ophthalmic lens for mounting in a surround of an eyeglass frame, the surround presenting a generally profiled shape with an inside face provided with a first engagement ridge or groove and lying between a rear margin for being turned towards the face of the wearer of the eye...

Beschreibung
Zusammenfassung:	A method of preparing an ophthalmic lens for mounting in a surround of an eyeglass frame, the surround presenting a generally profiled shape with an inside face provided with a first engagement ridge or groove and lying between a rear margin for being turned towards the face of the wearer of the eyeglass frame and an opposite front margin, the method including: acquiring the three-dimensional shape of an acquired longitudinal profile running along the inside face; and shaping the ophthalmic lens so as to form on its edge face a second engagement ridge or groove extending along a deduced longitudinal profile of three-dimensional shape calculated as a function of the shape of the acquired longitudinal profile. The method further includes acquiring a geometrical characteristic that relates to the position of the engagement ridge or groove relative to the front and/or rear margin of the frame, the shape of the deduced longitudinal profile then also being calculated as a function of the geometrical characteristic.
