Bad thing is I already need and have bifocals, Have one of the headlights that have magnifiers that flip down. But have to get to close to use them, Have the magnifying lights like Firestoper has, But oil etc get on them. Have looked for a nice size magnifying glass to keep with the lathes. Have thought about the dental/surgeons loops but have not found any that work on my glasses, they all come on ones that will not fit over my glasses. So I am like all the suggestions.
