摘要： A method is provided for providing a selection chart of non-prescription ophthalmic lenses. The method comprises providing at least one optical performance parameter threshold (OPPT) associated to an optical performance parameter (OPP); choosing the selection criterion (SC) among the selection criteria of the list consisting of: lens base curve; lens pantoscopic angle; and lens wrap angle; choosing a selection criterion range (SCR) for each of the chosen selection criterion; calculating selection domains (SD) defined by sub-ranges for each of the chosen SC within the SCR so as to determine and associate in each SD a single non-prescription ophthalmic lens with a spherical front surface, a complex back surface and a lens base curve. All the chosen OPPs are equal or less to the OPPT for all values of the SC within the SD associated to the single non-prescription ophthalmic lens.

摘要： This computer-implemented method for automatically evaluating a relevance of a design of an eyeglasses frame includes: obtaining a predetermined frame having a predetermined design; obtaining information relating to a current representation of the predetermined frame; and evaluating, by at least one processor, a relevance of the predetermined design, from the current representation, according to at least one predetermined relevance criterion and providing, by the at least one processor, a feedback including a result of the evaluating.

摘要： A method for determining an optical lens adapted for a wearer and optimized for at least a given optical criterion having a target value around a specific gaze direction. The method includes determining an intermediate optical lens by optimizing, using an optimization function, an initial optical lens so that the difference between the value of the at least given optical criterion of the intermediate optical lens and the target value of gaze directions around a specific gaze direction is smaller than or equal to a threshold value, and determining the optical lens by optimizing the intermediate optical lens so as to obtain the largest zone of gaze directions around the specific gaze direction for which the difference between the value of the at least given optical criterion and the target value around the specific gaze direction is smaller than or equal to the threshold value.
