when they are prescribed and ground properly, that bifocal line is virtually un-noticeable - I hardly ever notice mine except in rare cases where I tilt my head back to get a little more magnification at a middling distance. May have to try a few different brands/pairs to find a pair that sits comfortably and the bifocal split is in "just the right spot" - they are not all the same (unless different brands are just re-branded from the same manufacturer)Whether the bifocal line is a pita will be personal choice.
It is possible to get safety glasses in which the whole lens is a magnifying/reading lens. They're not as prevalent as the bifocal kind. There are drawbacks to this approach, too, but for those who have trouble using the little bifocal, an alternative exists.Last one’s I purchased 4-5 yrs ago are Dewalt. There are a slimmer, lighter frame design that I prefer. I dont wear them when turning. They dont give me the broader field of vision of regular reading glasses. When turning I dont want to tilt my head up and down constantly vs moving my eyes while making a cut. So yeah, I violate safety stds by not wearing safety glasses under an approved face shield.
Yeah, that's what I use. I need magnification to see what I'm turning. I never liked that I had to hold my head just so in order to see thru the bifocal bit. I wear full-lens reader safety glasses at the lathe or bench, and just deal with not being able to see across the shop without removing them.It is possible to get safety glasses in which the whole lens is a magnifying/reading lens.

Bob - try zenni.com or one of the other on-line lens manufacturers. I've worn glasses most of my life, and progressive bifocals for the last 20yrs. The last few pair have come from on-line because price is so much better. I even had one set made up with full bifocal magnification grind for working when I need to see up close above me (like working under sinks, etc), an electrician told me he had his bifocals ground with magnification on top instead of bottom for working overhead.Had cataract surgery a year ago. Opted for distance which requires reading glasses at 3.0 for 8-10” but they do little for times when I need to focus on things that are 4-5” away. Still looking for single safety glasses that offer no correction on top, reading @3.0 and magnification for very close in work.
Guessing that I am looking at prescription lenses with blended trifocal grind ($$$).
Thanks, Ron. I will give them a call.Bob - try zenni.com or one of the other on-line lens manufacturers. I've worn glasses most of my life, and progressive bifocals for the last 20yrs.

Any pic of these to see if they can be found around here? Or a shop that carrys?yes the maqgnifying glass helps alot I used to use a mounted glass on a swing arm but since getting the head one I havent usedit the head one also has alight on it that you can swing up or down and this with the magnifying lens that also swings is great.
I suspect he means something like this: https://smile.amazon.com/gp/product/B0752B9YGV/ I have them, very handy for close work, especially when I am cutting dovetails and/or sharpening chisels & plane irons, etc. Only drawback is they can't be worn with most typical faceshields, I don't think.Any pic of these to see if they can be found around here?

Probably, I was hoping more for something like goggles that could be worn over rx glasses.I suspect he means something like this: https://smile.amazon.com/gp/product/B0752B9YGV/ I have them, very handy for close work, especially when I am cutting dovetails and/or sharpening chisels & plane irons, etc. Only drawback is they can't be worn with most typical faceshields, I don't think.
