Method for manufacturing a personalized frame based on 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, the personalized frame being intended to accommodate visual correction personalized ophthalmic lenses and a geometric definition of at least one of said personalized ophthalmic lenses intended to be mounted in said personalized frame, wherein: - a reference frame chosen by the wearer is identified, - the value of at least one geometric parameter of personalization (P perso) of the personalized frame is 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 personalized frame with respect to the morphological quantity of the head of the wearer, comprising a constraint on at least one geometrico-morphological parameter related to the relative position of said personalized frame with respect to the head of the wearer, - the geometric definition of said personalized frame is determined based on said at least one geometric parameter of personalization (P perso) of the personalized frame and of the reference frame chosen by the wearer by deforming a geometric definition of the reference frame so that the geometric definition of the personalized frame resulting from this deformation conforms with said geometric parameter of personalization (P perso), with an adjustment on the head of the wearer in conformity with said criterion of adjustment of personalization, without constraint on preservation of at least one of the following dimensions of the reference frame: the perimeter of the rims, the reference frame outline curvature, and - the geometric definition of the personalized ophthalmic lenses is determined together with the geometric definition of the personalized frame, at the same time thereas, and - said personalized frame is manufactured in conformity with said determined geometric definition. - a reference frame chosen by the wearer is identified, - the value of at least one geometric parameter of personalization (P perso) of the personalized frame is 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 personalized frame with respect to the morphological quantity of the head of the wearer, comprising a constraint on at least one geometrico-morphological parameter related to the relative position of said personalized frame with respect to the head of the wearer, 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 personalized frame with respect to the morphological quantity of the head of the wearer, comprising a constraint on at least one geometrico-morphological parameter related to the relative position of said personalized frame with respect to the head of the wearer, - the geometric definition of said personalized frame is determined based on said at least one geometric parameter of personalization (P perso) of the personalized frame and of the reference frame chosen by the wearer by deforming a geometric definition of the reference frame so that the geometric definition of the personalized frame resulting from this deformation conforms with said geometric parameter of personalization (P perso), with an adjustment on the head of the wearer in conformity with said criterion of adjustment of personalization, without constraint on preservation of at least one of the following dimensions of the reference frame: the perimeter of the rims, the reference frame outline curvature, and - the geometric definition of the personalized ophthalmic lenses is determined together with the geometric definition of the personalized frame, at the same time thereas, and - said personalized frame is manufactured in conformity with said determined geometric definition.
