Goggles device, goggles, method for operation

A glasses device, having a see-through unit which includes at least one darkening element, which is configured for darkening at least one subregion of the see-through unit, and having a light sensor unit, which is configured to generate a sensor signal dependent on an ambient brightness, which is the basis for a degree of a darkening of the darkening element, comprising a switch-off unit, which provides at least one switch-off function for the sensor signal of the light sensor unit, wherein the switch off unit includes a mechanical cover element, which is configured in at least one operation state to at least essentially completely cover at least all measurement regions of the light sensor unit, wherein the mechanical cover element is configured in at least one further operation state to only partially cover the measurement regions of the light sensor unit and wherein the mechanical cover element includes at least one pass-through opening, which is partially or completely bordered in a circumferential direction by the cover element, which in at least one further operation state completely overlaps with at least one measurement region of the light sensor unit, and which in the operation state is free of overlap with the at least one measurement region.
