ABSTRACT:
An optical apparatus uses a variable-optical-characteristic optical element whereby focusing, zooming or the like can be effected without moving a lens or the like and the whole optical apparatus can be arranged in a lightweight structure. The user wears a power transmitting unit303by hanging it from his/her neck, for example. The power transmitting unit303may be put in a clothes pocket or the like. The power transmitting unit303may be placed somewhere around the user. In the power transmitting unit303, a transmitting circuit305is driven by a power supply304to send an electromagnetic wave from a transmitting antenna306toward variable-focus eyeglasses302. The variable-focus eyeglasses302have a receiving antenna307provided on eyeglass frames308to receive the electromagnetic wave sent from the power transmitting unit303. The received electromagnetic wave is, for example, boosted in voltage and rectified to drive the variable-focus lenses.
