I have darkening bifocals. And I have a NexGen. I am running it at a 9 shade now. If I am out in the sun, and my bifocals get dark, should I go lighter on the NexGen? Doing 1/8" 7018, but do a lot of MIG, .030" with CO2.
The darkening glasses respond to UV - UV which is blocked by the welding lenses. If they are darkening when worn under your welding helmet, you have a problem, possibly with UV leaking under the helmet where you might need a neck shield.
Personally..Ive got correction lenses in all of my hoods. Now my vision isnt too bad, can function without correction..but I got a bit far sighted after the stroke.
My primary helmet is an Optrel Satellite, a gift from a guy who cant weld anymore
Ive talked to a lot of guys who simply cannot weld with bifocals and do as I do..put in correction lenses inside their helmets.
I use one lightweight helmet with stronger correction in it for TIG, but the rest of them use 1.5 lenses

My vote would be to ditch the glasses, and use headgear that has the corrective lens built right it to it. You can get the corrective lens from any welding shop and they are the same size as the filter. I have had many students that wear bifocals or glasses in general do much better when they arent fighting image distortion and depth perception issues of wearing glasses and goggles seperately. "
