Abstract: Method for optimizing an optical lens equipment for a wearer Method for optimizing an optical lens equipment for a wearer, the method comprising:—an eye tracking device providing step, during which a spectacle frame mounted eye tracking device is provided to the wearer, —a wearer parameter monitoring step, during which at least one parameter relating to the eyes of the wearer is monitored using the eye tracking device and—an optimization step during which the optical lens equipment is optimized based at least partly on the base of the monitoring of the at least one parameter during the wearer parameter monitoring step.
