The utility model relates to the technical field of frame, in particular to an electronic luminosity-change frame, which comprises a frame shell. The utility model is characterized in that the frame is provided with an electric discoloring semiconductor apparatus and an opto-electrical control circuit connected with the apparatus, wherein, the opto-electrical control circuit is connected with an optical sensor, the components of the electric discoloring semiconductor apparatus are as follows: an upper surface and a lower surface in the surrounding are respectively provided with a transparent conduction layer, and an electric discoloring layer, an ion conductor and an ion storage layer are ordered in series in the middle layer; the beneficial effect of the utility model is that optical filtering coefficient can be changed automatically along the intensity of light getting through a lens, when illumination is not enough, optical filtering coefficient of an electronic discoloring frame is equal to transmit coeff
