Abstract
The method for manufacturing a frame of a pair of spectacles from at least one lens to be inserted therein, in a manner that said frame is adapted to the shape and dimensions of the lenses, comprises: a step of scanning to obtain a representation, in at least two dimensions, of a contour of at least one lens by means of a file comprising information representative of the contour, a step of computing a frame of a pair of spectacles on the basis of the representation of the contour of each lens and a step of controlling a machine for manufacturing the computed frame.
Claims18
A device for manufacturing a frame of a pair of spectacles from at least one lens to be inserted therein, such that said frame is adapted to the shape and dimensions of the lenses, which device is characterised in that it comprises:
- a scanner configured to represent, in at least two dimensions, a contour of at least one lens and supply a file comprising information representative of this contour;
- a means for computing the frame of a pair of spectacles suitable for receiving and holding each lens, on the basis of the representation of each lens contour;
- and
- a means for controlling a machine for manufacturing the computed frame.
