The utility model relates to a photosensitive circuit which adopts the electronic equipment and the electronic technology, and does not adopt the mechanical structure, and the photosensitive circuit of the photosensitive electron tube is used as the photosensitive element to control the generation of the corresponding optical transmission rate under the condition of different brightness. When the light beam passes through the lens, the photosensitive circuit receives the light signal, and generates an electric signal to control the light transmittance of the electrochromic lens, and provides the filtering light and the super light for the video camera or the image shooting. When the light beam is strong, the light transmittance of the lens is reduced, and when the light beam is weak, the lens light transmittance is improved, and the lens can be used under the conventional brightness.
