Method for adapting the optical function of an adaptive ophthalmic lenses system, the method comprising: - an adaptive ophthalmic lenses system providing step, during which an adaptive ophthalmic lenses system is provided, the adaptive ophthalmic lenses system comprising: o a pair of adaptive ophthalmic lenses, and o at least one light sensor configured to acquire the scene facing the wearer through a functionalized optical system providing functionalized images of the scene, the functionalized optical system is arranged so as to have at least one working distance, and o an eye tracking device arranged to determine a gazing direction of the wearer, - an acquisition step, during which the scene in front of the wearer is acquired by the light sensor through the functionalized optical system, - a gazing zone determining step, during which a gazing zone is determined, the gazing zone being a zone of the images of the scene acquired during the acquisition step comprising the gazing direction of the wearer, - a parameter determining step, during which the value of at least one parameter of the images of the scene acquired during the acquisition step is determined in the gazing zone of the images of the scene, the at least one parameter is related to the sharpness of the functionalized images of the scene in the gazing direction, - a comparison step during which the sharpness of the functionalized images of the scene in the gazing direction is compared to a threshold value, and - an adaptation step, during which the optical function of the adaptive ophthalmic lenses system is adapted so as to provide clear vision to the wearer according to the value of the at least one parameter determined during the parameter determining step, and wherein the adaptive ophthalmic lenses is adapted so as to provide clear vision to the wearer at the working distance when the sharpness is greater or equal to the threshold value. - an adaptive ophthalmic lenses system providing step, during which an adaptive ophthalmic lenses system is provided, the adaptive ophthalmic lenses system comprising: o a pair of adaptive ophthalmic lenses, and o at least one light sensor configured to acquire the scene facing the wearer through a functionalized optical system providing functionalized images of the scene, the functionalized optical system is arranged so as to have at least one working distance, and o an eye tracking device arranged to determine a gazing direction of the wearer, o a pair of adaptive ophthalmic lenses, and o at least one light sensor configured to acquire the scene facing the wearer through a functionalized optical system providing functionalized images of the scene, the functionalized optical system is arranged so as to have at least one working distance, and o an eye tracking device arranged to determine a gazing direction of the wearer, - an acquisition step, during which the scene in front of the wearer is acquired by the light sensor through the functionalized optical system, - a gazing zone determining step, during which a gazing zone is determined, the gazing zone being a zone of the images of the scene acquired during the acquisition step comprising the gazing direction of the wearer, - a parameter determining step, during which the value of at least one parameter of the images of the scene acquired during the acquisition step is determined in the gazing zone of the images of the scene, the at least one parameter is related to the sharpness of the functionalized images of the scene in the gazing direction, - a comparison step during which the sharpness of the functionalized images of the scene in the gazing direction is compared to a threshold value, and - an adaptation step, during which the optical function of the adaptive ophthalmic lenses system is adapted so as to provide clear vision to the wearer according to the value of the at least one parameter determined during the parameter determining step, and wherein the adaptive ophthalmic lenses is adapted so as to provide clear vision to the wearer at the working distance when the sharpness is greater or equal to the threshold value.
