Abstract
A method for manufacturing a spectacle lens according to at least one data set of edging data and a computer program product with instructions for performing the method are disclosed. A spectacle lens blank, semifinished spectacle lens product, or a finished spectacle lens product is inspected for defects and compared to a data set to determine if it can be manufactured into an edged finished spectacle lens that fits into a specific spectacle frame such that the defect is not present in the edged finished spectacle lens.
Claims14
A method of assigning a spectacle lens blank or a spectacle lens semifinished product or a spectacle lens finished product to a category, the method comprising:
- providing at least one of a plurality of spectacle lens blanks, a plurality of spectacle lens semifinished products, or a plurality of spectacle lens finished products;
- identifying a spectacle lens blank, a spectacle lens semifinished product, or a spectacle lens finished product having at least one defect;
- separating at least one of spectacle lens blanks, spectacle lens semifinished products, or spectacle lens finished products having the at least one defect from spectacle lens blanks, spectacle lens semifinished products, or spectacle lens finished products not having the at least one defect;
- detecting, with a recording device, a position, a size, or the position and the size of the at least one defect;
- providing a data set of edging data;
- comparing the data set of edging data with the detected defect;
- and
- assigning the at least one of the plurality of spectacle lens blanks, the plurality of spectacle lens semifinished products, or the plurality of spectacle lens finished products to a category depending on the comparison between the data set of edging data with the detected defect,
- wherein the spectacle lens to be produced, according to the at least one data set of edging data, is positioned virtually on an image recorded with the recording device on a part of the surface of the spectacle lens blank or on a part of an optically effective target surface of the spectacle lens semifinished product or on a part of one of an optically effective target surface of the spectacle lens finished product, which in each case has no defect.
A computer program product for assigning a spectacle lens blank or a spectacle lens semifinished product or a spectacle lens finished product to a category, the computer program product being stored on a non-transitory computer-readable storage medium and having instructions to:
- provide at least one of a plurality of spectacle lens blanks, a plurality of spectacle lens semifinished products, or a plurality of spectacle lens finished products;
- identify a spectacle lens blank, a spectacle lens semifinished product, or a spectacle lens finished product having at least one defect;
- separate at least one of spectacle lens blanks, spectacle lens semifinished products, or spectacle lens finished products having the at least one defect from spectacle lens blanks, spectacle lens semifinished products, or spectacle lens finished products not having the at least one defect;
- detect, with a recording device, a position, a size, or the position and the size of the at least one defect;
- provide a data set of edging data;
- compare the data set of edging data with the detected defect;
- and
- assign the at least one of the plurality of spectacle lens blanks, the plurality of spectacle lens semifinished products, or the plurality of spectacle lens finished products to a category depending on the comparison between the data set of edging data with the at least one detected defect,
- wherein the spectacle lens to be produced, according to the at least one data set of edging data, is positioned virtually on an image recorded with the recording device on a part of the surface of the spectacle lens blank or on a part of an optically effective target surface of the spectacle lens semifinished product or on a part of one of an optically effective target surface of the spectacle lens finished product, which in each case has no defect.
