A method 300 and device for visual compensation captures 330 an image using an imager, detects 360 whether eyeglasses are present in the image, and sets 363 an electronic visual display to a normal font size, if eyeglasses are detected as present in the image. The control server is in communications with both the controller and the networked device having a communication port for such communications. Through the control of the resonance frequencies of the series resonance circuits, the parallel resonance frequency of the whole antenna is tuned to a desired frequency, and the resonance characteristic in which the impedance is matched to a specific value, e.
