Method means for optimizing an optical lens adapted to a wearer, using an initial optical system providing stage (S), during which an initial optical system is provided. The initial optical system has at least a light source (), a light receiver () and an initial optical lens (L) placed between the source () and the receiver (), the initial optical lens a Fresnel zone, a working optical lens defining stage (S), for evaluating a working optical lens is defined to be equal to the initial optical lens (L), an evaluation stage (S), during which a cost function related to the number of light rays received by the light receiver () that have passed through the annular step of the working optical lens, a modifying stage (S), for modifying the annular step of the working optical lens, wherein the evaluation and modifying steps are repeated to minimize the cost function.

Method for optimizing a Fresnel optical lens

Method for defining one face of an ophthalmic lens, having a surface formed by superposing a Fresnel layer and a continuous surface referred to as the 'carrier'. Also disclosed is an ophthalmic lens comprising such a face. The method allows a Fresnel layer to be defined that compensates for geometric effects induced by a variation in the curvature of the carrier on the light incident on the face of an ophthalmic lens. This method is particularly useful when the curvature of the face of the ophthalmic lens is adapted to facilitate fitting it into a spectacle frame.

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.
