Embodiments of the present disclosure provide a visual fatigue intervention method based on effective working hour accumulation and safety fusing, applied to the technical field of intelligent wearable devices. The method comprises real-time collection of motion state data and
gaze state data of the wearer, based on the joint determination result, performing accumulation or holding operation on the effective working hour counter; when the accumulated value reaches the preset intervention trigger threshold, the current scene
risk level and the real-time motion state of the wearer are combined to determine the intervention execution opportunity, the optical modulation lens of the spectral intervention glasses is switched to a specific spectral intervention state, and the external interaction
signal is shielded; during the duration of the specific spectral intervention state, the physiological rest behavior characteristics of the wearer are monitored in real time, and when the behavior characteristics that meet the preset relaxation conditions are detected, the optical modulation lens is driven to return to the transparent working state, the shielding of the external interaction
signal is removed, and the effective working hour counter is cleared. In this way, it can ensure that the user completes the real eye
relaxation behavior.
