Umm. Not that I have any PERSONAL experience with age related failings,
such as reduced visual acuity, but having spent a lot of time with aging
craftspeople I can provide a few suggestions:
1) "Cheater Lens" (magnifiers) for most welding hoods are available in
several strengths from your local welding supply.
2) Many welders prefer dual bifocals (bifocal ground in the top and the
bottom of the lens) because they can still see (down and up) when they lift
3) A "reading glass" prescription works quite well and lets you see
everything you are working on (but does sort of limit object recognition
outside arms reach).
