You can order several types of prescription lenses that are shatter resistant and suited for shop use. I have a pair or two of these with progressive prescriptions for my far sightedness. Hard for me to see up close without them.
I have the Rockler ventilated dust maske (pix) that expels air over my cheeks, which clears any condensation on the lenses. I keep two sets of rechargable batteries ready to go. Each lasts about 3 hours. I really like having the positive pressure, filtered air that keeps all dust out. Fits nicely despite my considerable Gaulish proboscus.
The more I do, the less I accomplish.
