Abstract
The invention is based on a protection device, in particular a glare-protection device, with at least one optical glare-protection filter comprising a nose cut-out, with at least one sensor unit, which is provided to capture a work state and to control, depending on this, a permeability of the glare-protection filter, with at least one shield unit, in which the at least one glare-protection filter is fixedly accommodated, and with at least one head-fastening unit for a fastening to a user's head. It is proposed that the protection device comprises at least one adjusting unit, by which a position of the at least one shield unit is implemented in such a way that it is movable with respect to the at least one head-fastening unit in a defined manner.
