Been looking for a long time to replace my old safety magnifer glasses.
Found this place
These are NOT Bifocals but the whole lens is a magnifier.
Bought a pair years ago at Woodcraft and have never seen them again till these.
Good, quick service. I picked up 2 pair.
They also have powered faceshields. Not sure on their prices compared to others but give them a look.
No affilation - just a happy customer who finally replaced his glasses.
I checked their price for the Trend Airshield = $232
