Patent ID: 10409086

Abstract:
Method means for optimizing an optical lens adapted to a wearer, using an initial optical system providing stage (S1), during which an initial optical system is provided. The initial optical system has at least a light source (10), a light receiver (12) and an initial optical lens (L0) placed between the source (10) and the receiver (12), the initial optical lens a Fresnel zone, a working optical lens defining stage (S2), for evaluating a working optical lens is defined to be equal to the initial optical lens (L0), an evaluation stage (S3), during which a cost function related to the number of light rays received by the light receiver (12) that have passed through the annular step of the working optical lens, a modifying stage (S4), for modifying the annular step of the working optical lens, wherein the evaluation and modifying steps are repeated to minimize the cost function.
