The invention relates to a method for determining an usage index value for an single-vision ophthalmic lens adapted to correct the vision of a myopic wearer. According to the invention the method comprises: an optical profile providing step Sduring which an optical profile of said ophthalmic lens is determined; a material profile providing step Sduring which a material profile of said ophthalmic lens is determined; a physical parameter determining step Sduring which at least one physical parameter among physical parameters of said optical profile and material profile is determined; a gain assessing step Sduring which at least two gains brought by at least one determined physical parameter is evaluated on at least one evaluation criterion of dissatisfaction of said wearer when wearing said ophthalmic lens; an usage index value determining step Sduring which a value of an usage index is determined by adding the assessed gain for the evaluation criteria.

The disclosed embodiments include a method for determining a geometric definition of a piece of personalized optical equipment adapted to its wearer, comprising at least one geometric definition of a personalized frame of this piece of personalized equipment. In one embodiment, the geometric definition of said personalized frame is determined depending on at least one geometric parameter of personalization of the frame and on a reference frame chosen by the wearer. Further, the value of said at least one geometric parameter of personalization of the frame being determined on the basis of the acquisition of data relating to at least one morphological quantity of the head of the wearer, in such a way that the personalized frame is adjusted to conform with a least one criterion of adjustment of personalization of the geometry of the frame with respect to the morphological quantity of the head of the wearer.
