Abstract:
An indicator system and method for an auto-darkening lens or other device that is intended to be placed relatively close to the face of a wearer includes one or more indicators adjacent the lens and generally provides the indicators in the peripheral field of view of the wearer, allowing the indicators to be discerned without having to focus eye vision on them and while allowing the wearer to direct eye focus on a work piece or the like.
