The present invention relates to obstacle detection glasses helping blinds to see ahead well. The glasses have an ultrasonic sensor (10), a busser board (11), and a power button attached on a frame of the glasses, so the sensor detects an obstacle, if the obstacle exists, and rings an alarm bell. The ultrasonic sensor (10) of the obstacle detection glasses is ultra small, thereby being installed inside the glasses frame, and measuring a distance. The busser board (11) recognizes the transferred signal of an obstacle detected by the ultrasonic sensor (10) and makes an alarm sound. Therefore, the purpose of the present invention is reducing use of a raw material, consumed for the invented product by attaching the ultrasonic sensor and the busser to the frame of the glasses, and performing a function practical enough without using complex techniques. |
