Abstract

A method for manufacturing a corrective ophthalmic glasses lens personalized for a wearer, includes defining and digitally recording the configuration parameters of the lens, calculating modeling data of the refractive faces of the lens, and manufacturing the lens in accordance with the configuration parameters. The method includes the following steps: recording at least one ordered execution sequence of different interactive configuration software modules, each module being associated with one of the configuration parameters and including, in a graphical interface, selecting at least one configuration parameter value associated with the module from a preselection of values of the parameter, graphically simulating a virtual lens obtained with the selected value of the configuration parameter, confirming the selection of a configuration parameter value, executing the at least one ordered sequence; at the end of the execution of each module, recording the selected, confirmed value of the configuration parameter associated with the module.

First claim

The invention claimed is:

1. A method for manufacturing a corrective ophthalmic spectacle lens personalized for a wearer, comprising the steps of:
defining and recording, by computer, configuration parameters of the lens, these configuration parameters comprising optical design parameters of the lens, including a refraction correction prescription for the wearer and an optical design model,
manufacturing the lens in accordance with the configuration parameters,
wherein, to define the configuration parameters of the lens, the method comprises the following steps:
recording a plurality of ordered sequences of execution of various interactive configuration parts of code of a computer program, and selection, from among the plurality of ordered sequences, of one part of code according to which the modules are executed, each part of code being associated with one of the configuration parameters and comprising, in a graphical interface, a pop-up menu or area selectable by pressing the computer mouse-button for selection of at least one configuration parameter value associated with the module from among a preselection of values of this parameter, a graphical interface and scripts configured for graphical simulation of a virtual lens obtained with the selected value of the configuration parameter, a pop-up menu or area selectable by pressing the computer mouse-button for validation of the selection of a value of the configuration parameter,
executing said ordered sequence selected at the previous step;
on completion of the execution of each part of code of said ordered sequence selected, recording the selected and validated value of the configuration parameter associated with this module;
selecting of at least one view of the wearer and display of said view of the wearer as background layer of an area of the graphical interface;
simulating by an image of a corrective filter associated with the selected value of the configuration parameter of the lens;
displaying of the image of the corrective filter superimposed by transparency on said view of the wearer as background layer of said area of the graphical interface, so as to simulate the lens as worn by the wearer, said lens being personalized in accordance with the selected value of the configuration parameter associated with said ordered sequence;
executing another ordered sequence;
on completion of the execution of each module of said another ordered sequence selected, recording another selected and validated value of another configuration parameter associated with said another ordered sequence;
displaying of said view of the wearer as a second background layer of a second area of said graphical interface;
simulating by a second image of a second corrective filter associated with the selected value of said another configuration parameter of another lens; and
displaying of the second image of the second corrective filter superimposed by transparency on said view of the wearer as background layer of the second area of said graphical interface, so as to simulate said another lens as worn by the wearer, said another lens being personalized in accordance with the selected value of said another configuration parameter, so as to allow the comparison of at least two personalized virtual lenses as appearing when worn by the wearer.

2. The method for manufacturing a corrective ophthalmic lens as claimed in claim 1 , comprising, on completion of the execution of the part of code of said ordered sequence, a step of using the configuration parameter value selected and validated at the end of the execution of said part of code, so as to determine a preselection of values of the configuration parameter for a subsequent part of code of said sequence.

3. The method for manufacturing a corrective ophthalmic lens as claimed in claim 1 , wherein the configuration parameters of the lens comprise manufacturing parameters of the lens, including the distribution of the optical power function, the material of the lens, the color of the lens, the polarization of the lens, the surface treatment(s) including anti-reflection treatment, impact resistance treatment, anti-scratch treatment, antistatic treatment, water-repelling treatment, grease-repelling treatment, polarizing treatment, the photochromy property of the lens, and/or geometric and morphological parameters relating to the wearer and to a spectacle frame.

4. The method for manufacturing a corrective ophthalmic lens as claimed in claim 1 , wherein the execution of at least one of the parts of code comprises the following steps:
selection of at least one image representative of a visual setting and display of said image as background layer of a graphical area of the graphical interface of the part of code concerned;
simulation of a corrective filter associated with the selected value of the configuration parameter of the lens;
display of the corrective filter superimposed by transparency on said image as background layer, so as to simulate the vision of the wearer through a virtual lens personalized in accordance with the selected value of the configuration parameter associated with the part of code.

5. The method for manufacturing a corrective ophthalmic lens as claimed in claim 4 , further comprising the following steps:
selecting a second image representative of a visual setting and display of said second image as background layer of a second graphical area of the graphical interface of the part of code concerned;
simulating a second corrective filter associated with another value of the configuration parameter of the lens;
displaying the second corrective filter superimposed by transparency on said second image as background layer of the second graphical area so as to simulate the vision of the wearer through a second virtual lens personalized in accordance with the other value of the configuration parameter, so as to allow the comparison of at least two personalized virtual lenses.

6. The method for manufacturing a corrective ophthalmic lens as claimed in claim 1 , wherein the execution of at least one of the modules comprises the following steps:
selecting at least one view of the wearer and display of said view of the wearer as background layer of an area of the graphical interface of the parts of code concerned;
simulating a filter of shape and of aspect of the lens as a function of the selected value of the configuration parameter associated with the part of code;
displaying the filter of shape and of aspect of the lens superimposed by transparency on the background layer so as to simulate an image of the lens worn by the wearer and personalized in accordance with the selected value of the configuration parameter associated with the part of code.

7. The method for manufacturing a corrective ophthalmic lens as claimed in claim 6 , wherein the step of selecting at least one view of the wearer comprises the selecting of a sequence of images or of an image in three dimensions.
