1. A system for disinfecting an environment, the system comprising:

  • a germicidal radiation emitter that emits germicidal radiation into the environment to disinfect the environment;

    a sensor configured to detect whether a person in the environment is wearing eye protection on a head of the person and over eyes of the person; and

    processing circuitry communicatively coupled to the germicidal radiation emitter and the sensor, wherein the processing circuitry is configured to operate the germicidal radiation emitter to emit germicidal radiation into the environment in a first mode in response to detecting that the person is wearing the eye protection in the environment, and in a second mode in response to detecting that the person is not wearing the eye protection in the environment, with the second mode being a lower amount of germicidal radiation being emitted into the environment than the first mode;

    the second mode including either a positive amount of the germicidal radiation being emitted into the environment or no germicidal radiation being emitted into the environment.
