The invention discloses 3D (three-dimensional) intelligent spectacles which comprise a spectacle frame body, a telescopic lens frame, a connecting arm and an infrared source sensing device. 3D lenses are arranged on the lens frame; one end of the connecting arm is pivotally connected with the spectacle frame body, and the other end of the connecting arm is slidably connected with the lens frame; the spectacle frame body further comprises voice modules; the infrared source sensing device is arranged on the spectacle frame body, and variable-focus lenses are arranged in the spectacle frame body. The 3D intelligent spectacles have the advantages that a wearer only needs to slide down and turn the lens frame when 3D film sources are demonstrated during conferences, so that the 3D intelligent spectacles can be turned into 3D spectacles; the lens frame can be pushed up when demonstration is not required in speech environments during the conferences, so that the wearer can observe the speech environments without the lenses, and the 3D intelligent spectacles are suitable for different myopic people during watching.
