I made the semi-stupid mistake of buying some flip-up lenses from
Micro-Mark. They were on sale but only the #10 strength was available.
These were great for seeing when attached to my reading glasses.
Problem was they were so thick and heavy they always slid off my nose!
I went back to my Opta Visor.
