The safety range adjustment module 100 may be configured to set a threshold value by adjusting a variable resistor or a potentiometer, or may be configured to set a threshold value by programming control.

In some embodiments, the safety range adjustment module 100 includes an adjustment knob (e.g., a rotary variable resistor) that can be used to manually adjust different decision thresholds (safety thresholds) according to the needs of the user.

If the power is within the safe range, the therapeutic apparatus continues to operate, and the detection module and the optical power judging module 500 still make real-time feedback on the optical power. In consideration of different severity of xerophthalmia and different users, the requirements and tolerance of the light intensity are different, and the safety range adjusting function is added, so that the applicability of the dry eye safety device is improved.
