#10 tradesman auto darkening lens

[mechanic]

I have had this lens for over 20 years and still works but it seems that it is getting darker when using it. I start seeing then it seems to be harder to see. Like it is getting darker, not sure. These lens are expensive so I thought a pair of harbor freight yellow tinted safety glasses might brighten the area around the weld. I can see the puddle but the area around that I am welding or joint is too dark to see. Maybe going to a #9. This might be to light. I guess I'll have to experiment. Anyone else solve this same issue. I have a gold #9 but at the very edge I see some gold missing. The part you look through is fine. I might try it and see if I can see better. Though I do remember using a # 9 stick welding and it was too bright. Have a answer to problem let me know. Thanks

Well noone would answer me. So figured it out. Number nine gold is the answer

Starting In 1990, Auto Darkening was the answer for me.
