Abstract
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.
