Is there a glazing option where the glass is etched on both sides? The conservaton reflection control from TruVue is etched on one side only. I am working with a PITA right now who insists that is what his previous framer (not local) used. To me, it just looks like really cheap, grainy, non-glare glass. If it is out there, who provides it? I need a really good answer for this PITA!
