Cheater in welding helmets

[Charley Davidson]

I use both and a pair of binoculars , then the front slag shield popped off so I only need one or the other, guess I need to replace it with a new one, I super glued my cheater in & it just recently popped off after several months. Only paid $5 for the auto darkening helmet at a garage sale about a year ago.

This is a rather old thread so I hope people are still reading and will respond .... Are the cheater lenses fresnel-based? Wondering if I can glue one in on the inside of my helmet.
