I'm getting well into my 40's now. I've had to go to the Walmart/Dollar tree cheapo cheater specs now. Only one in my family that wasn't wearing glasses. Anything closer than 20-24" just won't clear up. I can still manage welding without glasses but its more difficult because things just aren't as sharp. Finding cheater lens to fit my jackson locally isn't really easy...but its just the closest store. I can get it, but just haven't gone to the next town to buy them.
A word about needing light on the weld area: Generally. If you need it to see, you are using too dark of lens for you application. A number one mistake of many welders who are concerned about burning out their retinas. The wleding arc is bright as or brighter than the sun. All helmets worth their salt provide 100% UV protection and IR protection even in their clear state. So, your eyes are well protected except from the back flashing. Adjust your helmet darkness (if you have auto dark or if you don't...just buy several filters) so you can see at least 6 inches all around your weld, CLEARLY. If you can't see anything but the arc and just an inch or so in front, you are using too much filter. You should not have to strain to see the welding arc. The quick test is to run some beads on flat plate and try to make them straignt as possible. If they are wavy or curvy, it's likely you are welding with too dark of a lens shade.
