This creation mainly provides a kind of application ultrasonic to assist person visually impaired to sense what front obstacle in effective coverage and with warning； The ultrasonic glasses for guiding blind its be one glasses of what be equipped with a ultrasonic emitter,At least three ultrasonic receivers,One controller and at least a loudspeaker； Wherein,What glasses middle position is arranged in the ultrasonic emitter,And ultrasonic receiver system is respectively set on what glasses,The echo of the emitted wave frequency of ultrasonic emitter is detected by ultrasonic receiver,And by the controller operation echo time and with alarm obstruction object range-azimuth,And loudspeaker makes a sound power,With the distance of alarm obstruction object,Preceding object object is detected in order to reaching,Helping what prevents collision injured,To ensure safety when blind person walking.本創作主要提供一種應用超音波以協助視障者對於前方障礙物在有效區域內進行感測並以警示；所述超音波導盲眼鏡其係於一眼鏡設有一超音波發射器、至少三超音波接收器、一控制器及至少一揚聲器；其中，該超音波發射器設置於眼鏡中間位置，而超音波接收器係分別設置於眼鏡上，藉由超音波接收器偵測到超音波發射器所發射波頻的回波，且由控制器運算回波時間並以警示障礙物距離與方位，而揚聲器發出聲音強弱，以警示障礙物的距離遠近，俾達偵測前方障礙物體，有助於防止碰撞受傷，以保障盲者行走時的安全。
