Abstract: The invention relates to ophthalmic spectacles for characterizing the direction of gaze of a wearer. Each lens of the spectacles is provided with output sections for directing a radiation towards the ocular areas of the wearer, in which different portions of an ocular limbus of the wearer are in motion. The lens is further provided with input sections for collecting the portions of said radiation reflected in said ocular areas. A computing unit is also combined with the spectacles in order to determine the direction of gaze of the wearer from detection signals measuring the portions of the radiation that are simultaneously collected by the input sections of the two lenses.
