Method for verifying conformity with a predetermined criterion of use of a spectacle frame and associated device

A method, executed by a computer, for verifying a conformity of a spectacle frame with a predetermined criterion of use of said spectacle frame, said spectacle frame configured to receive two ophthalmic lenses, the method comprising the steps of:

• a) determining at least one of a geometrical, mechanical, and structural characteristic of the spectacle frame, said determining carried out either visually by an operator or by reading a frame identification file recorded on a data storage in communication with said computer and associated with said spectacle frame, and determining a frame category to which said spectacle frame belongs from a set of predetermined spectacle-frame categories recorded on the data storage in communication with said computer;
• b) determining an outline, in two or three dimensions, of at least one of i) a rim of said spectacle frame and ii) one of said ophthalmic lenses to be mounted in said spectacle frame, and storing said determined outline in the computer;
• c) evaluating a value of each parameter from a list of parameters of said spectacle frame recorded on the data storage in communication with said computer, said list being determined as a function of said frame category determined in step a), the value of at least one of the parameters evaluated by said computer as a function of said measured outline determined in step b), each value of the at least one of the parameters of the spectacle frame being associated with a score for the spectacle frame;
• and
• d) deducing the conformity of the spectacle frame to the predetermined criterion of use from the values of said parameters of the spectacle frame determined in step c) by comparing, by the computer, the score of the spectacle frame for each evaluated value with a reference score recorded on the data storage in communication with said computer and associated with the parameter associated with the value, each said reference score depending on said predetermined criterion of use.
