Abstract: A protective cartridge for a glare protection apparatus, includes an optical glare protection filter which, in particular, has at least one liquid crystal cell, including at least an open-loop and/or closed-loop control unit, which is configured to control and/or regulate a permeability of the optical glare protection filter, at least between at least one bright level and at least one dark level, depending on a captured work state, on an electronic signal of an external signal source and/or on light irradiation. The permeability of the optical glare protection filter at at least one bright level corresponds to a protection level of less than 2.5, preferably of at most 2.4, advantageously of at most 2.25, particularly advantageously of at most 2 and preferably of at most 1.7.

Abstract: An eye protection device for a welding mask or the like includes a welding activity detection circuit that is configured to detect welding activity, and a filter driver that controls an optical filter to be in undarkened and darkened states. The filter driver is configured to (i) provide a slower and/or gradual opening of the filter, (ii) insert a user-selected delay and/or gradient between the end of welding activity and the opening of the filter, and/or (iii) cause variation of light transmission values of the filter between a darkened state and an undarkened state based on varying brightness detected by a brightness sensor during transition of the filter from a darkened state to an undarkened state.
