A method of controlling shade of light valve for auto darkening filter includes: controlling the current shade of the light valve at a first shade, continuously detecting a welding arc signal until it is detected; controlling the first shade of the light valve to change to a target shade, and maintaining the target shade for welding work until the welding arc signal is interrupted; controlling the light valve to transition from the target shade to the first shade within a time period T.sub.2, wherein at least one intermediate shade is passed during the transition. For the conventional ADF, after the welding arc signal disappears, the control circuit immediately switches the light valve from the target shade to the light state shade. The switch of the light valve from the target shade to the light state shade occurs instantaneously, therefore the user may feel dazzling, causing damage to vision.

A replacement rear strap assembly is provided for use on a helmet that has a headgear assembly. The headgear assembly has a front strap, a top strap, a pair of hubs between the front strap and top strap, and a pair of connection bosses extending from the pair of hubs.
