The invention overcomes the problem that the existing automobile anti-theft device is insecure and unstable and discloses an automobile sun shield for controlling the secure startup of an automobile through retina identification. A rotation shaft of the sun shield is fixed to a fixed plate; a sun shield cover covers the sun shield; a window is formed in the sun shield cover; the rotation shaft at one end of the sun shield is connected with the output shaft of a stepper motor through a coupling; a tilt angle sensor and a retina identification device are installed between the sun shield and the sun shield cover; the stepper motor, the tilt angle sensor and the retina identification device are connected with a digital signal processor through respective wires; a control switch, a power supply module and a pressure sensor positioned at an automobile cabin seat are connected to the digital signal processor; the digital signal processor is connected with an automobile ECU. According to the invention, the startup of an automobile engine is controlled through retina identification, and thus the secure anti-theft performances of the automobile are enhanced.
