Zusammenfassung:	An auto-darkening eye protection apparatus 300 such as a welding helmet includes an externally located combined push button and rotary switch 302 coupled to lens control circuitry. A lens control setting display i.e. heads up display, is configured on an internal portion of the apparatus 300 and located in a field of view of a user when the lens is in a lowered operational position. The externally located combined push button and rotary switch 302 is operable to select and adjust lens control parameters by a user wearing bulky hand protection such as welding gloves or welding mittens. The selection and adjustment level of the lens control parameters can be monitored on the display during the adjustment by a user while the lens is in the lowered operational position.
