Abstract: This computer-implemented method for providing a finished single vision ophthalmic lens intended for a wearer, from a target lens having at least one complex surface, the finished lens having a rotationally symmetrical front surface, includes: providing wearer data or theoretical data; defining targeted optical or geometrical characteristics along a predetermined path on the target lens, based on the wearer data or on the theoretical data; determining the finished lens by: selecting an initial lens complying with the prescription data and having a rotationally symmetrical front surface and a predetermined curvature at a prescription reference point; defining a current lens as the initial lens; modifying a front surface definition of the current lens to reach the targeted optical or geometrical characteristics until an ending criterion is met; providing the finished lens as the current lens.

Abstract: A method for generating modified eyeglass frame manufacturing data including the following steps: a. providing a plurality of eyeglass frames; b. selecting one frame among the plurality of eyeglass frames; c. determining data relative to the selected frame; d. modifying the determined data whilst respecting at least one predetermined conception rule, so as to obtain modified data; and e. computing the modified data obtained by the modification so as to generate modified eyeglass frame manufacturing data.

Abstract: A method for determining an optical design criterion for designing an optical lens adapted to a sport practice, the method including: defining an evaluation axis for evaluating sensory/motor/cognitive requirement of a sport practice, for each of a plurality of sports; attributing a score to the sport practice on each evaluation axis; determining clusters of sports in which practices have similar score; determining at least one visual need corresponding to each cluster of sports; determining, for each cluster, at least one optical design criterion as a function of the associated visual need; and storing in a memory a record for each cluster, along with each optical design criterion associated with the cluster.
