Why can't you just wear your prescription glasses?



Greetings Leo,
I actually meant to post this in another newsgroup so maybe that's why
you asked but I'll still answer your question. My prescription lenses
can't give me the ability to see really tiny features. 20/20 vision is
fine for regular welding and my glasses work well for that. I need
magnifying glasses for doing work on tiny machined parts.

Eric, what works for me is a pair of flip up magnifying lenses. The
major difference between these and the telescopic ones that dentists use
these days is focal distance. If you don't mind being up close, the flip
ups are *much* cheaper.

I tried a couple of optometrists, including one catering to industrial
folks, all their flip ups were junk. The best ones I found were at a
fly-tying fisherman's shop.

These look like the ones I've got:

watch the line wrap. There are cheaper prices advertised than Amazon,
you pays your money and takes your chances.

Thanks Steve. I already have some of these. And of course they don't
match close enough the inter pupillary distance of my eyes. Most
people can tolerate this fairly well. Unfortunately I end up using one
eye with this type of magnifier. Either eye works but together the
image is slightly double. Close spaced vertical lines are a particular
problem.
