Glasses and control method thereof

The invention relates to glasses and a control method thereof. The glasses comprise eyeglasses, a photographic device and a mirror bracket; the eyeglasses and thephotographicdevice are correspondinglylocated on the mirror bracket; the eyeglasses is transparent displays; the control method of the glasses comprises the steps that the light intensity of ambient light is detected; according to the light intensity of the ambient light, and current light transmittance of the glasses, the current light intensity of transmission light after the ambient light passes through the eyeglasses is obtained;when the current light intensity mentioned above is higherthan or equal to the selected light intensity, andthe light transmittance of the eyeglasses is adjusted to make the light intensity of the transmission light be the selected light intensity; when the current light intensity mentioned above is lower than the selected light intensity, the photographic device is started off to obtain environmental images; the environm
