1. A method for adjusting a predetermined real spectacle frame (10) chosen by a given wearer for use by said wearer, comprising the steps of:

  • a) determining an at least partial model of the head (TS) of the wearer, with, in a given frame of reference, at least one model (MN) of a portion of the nose (N), and one model (MORD, MORG) of a portion of the ears (ORD, ORG);

    b) simulating the positioning of the spectacle frame (10) on the head (TS) of the wearer, by superposing, on the model of the head (TS) of the wearer, the corresponding zones of said spectacle frame (10) or of a model thereof, a superposition being generated therefrom;

    c) determining, from said superposition, a deformation of the spectacle frame (10) required to obtain a fit of said spectacle frame (10) on the head (TS) of the wearer meeting at least one predetermined fitting criterion; and

    following said determining step c), applying the deformation determined in step c) to the spectacle frame (10).
