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.
