Smart glasses for police looked like science fiction. Some Chinese officers have already started using them

Police in Tianjin, China, have begun using AI smart glasses during patrols and traffic checks to access real-time data.

The devices can read text and voice, identify people and vehicles, and have already helped find a missing elderly man and manage school-area congestion.

Officials say the system uses domestic hardware and software, with high accuracy and a growing range of connected uses.

The rollout highlights how AI and computer vision are moving into frontline policing, raising both efficiency gains and privacy concerns.
