ive read that too but any place i read it was just here say...

as for a fact,even when im grinding something with the auto dark lense it triggers off & cant use it..so..if it triggers off at that low of a light content just from grinding sparks i would think the lense gets dark enough before any damaging light gets through it
ive never had flash when welding with the auto lenses or even dry eyes from using them all day long none stop,if it was the case as they were saying it doesnt work fast enough i would of had flash from it or dry irritated eyes
