The distance measuring module is a distance measuring sensor provided on the glasses body, and the output module is a receiving earphone for receiving the distance measuring sensor signal. A control module for controlling the distance measuring module and the output module is also provided inside the glasses body. The guide glasses are provided with a distance measuring sensor and a receiving earphone. When using, the user only needs to turn on the switch, and the distance measuring sensor on the guide glasses will be in working state.
