Eye tracking spectacles comprising a frame , the frame having at least one receiving opening for receiving a disk-like structure, and wherein the frame has a U-shaped portion , which is provided for arranging the spectacles on the nose of a human, said U-shaped portion has a right nose frame and a left nose frame and a bridge between the right nose frame and the left nose frame , wherein a right eye detection camera is arranged in a right nose part frame , and in that a left eye detection camera is arranged in a left nose part frame , said spectacles further comprising a first earpiece and a second earpiece , characterized in that the left eye detection camera and the right eye detection camera are arranged in the corresponding nose part frame in a position with a Z coordinate referred to a Z axis of a Cartesian system in the range 3 mm≤Z≤15 mm, assuming said cartesian system (X, Y, Z) being placed with its origin corresponding to a maximum of a concave front profile of the U-shaped portion of the spectacles and X axis of the Cartesian System is parallel to the lower profile of the earpieces , being the plane XZ of the Cartesian system the symmetry plane of the spectacles , and Z axis is directed downward, thus avoiding the risk to have eyelids/eyelashes/cheekbones interferences considering also different nose shapes of different somatic traits of different ethnicities, during the detection of pupil center of a wearer when in use, and wherein the right eye detection camera and the left eye detection camera are oriented respect to the Z axis with an angle beta, wherein 17,5°≤beta≤22,5° thus allowing the spectacles to detect the possible pupil centers of a wearer of different ethnicities like for instance Asian people and European people when in use. a frame , the frame having at least one receiving opening for receiving a disk-like structure, and wherein the frame has a U-shaped portion , which is provided for arranging the spectacles on the nose of a human, said U-shaped portion has a right nose frame and a left nose frame and a bridge between the right nose frame and the left nose frame , wherein a right eye detection camera is arranged in a right nose part frame , and in that a left eye detection camera is arranged in a left nose part frame , said spectacles further comprising a first earpiece and a second earpiece , characterized in that the left eye detection camera and the right eye detection camera are arranged in the corresponding nose part frame in a position with a Z coordinate referred to a Z axis of a Cartesian system in the range 3 mm≤Z≤15 mm, assuming said cartesian system (X, Y, Z) being placed with its origin corresponding to a maximum of a concave front profile of the U-shaped portion of the spectacles and X axis of the Cartesian System is parallel to the lower profile of the earpieces , being the plane XZ of the Cartesian system the symmetry plane of the spectacles , and Z axis is directed downward, thus avoiding the risk to have eyelids/eyelashes/cheekbones interferences considering also different nose shapes of different somatic traits of different ethnicities, during the detection of pupil center of a wearer when in use, and wherein the right eye detection camera and the left eye detection camera are oriented respect to the Z axis with an angle beta, wherein 17,5°≤beta≤22,5° thus allowing the spectacles to detect the possible pupil centers of a wearer of different ethnicities like for instance Asian people and European people when in use. <EOS>
