We'll the Z5 didn't do as good of a job at filling in fine swirl marks as I expected. So I tested it out on my scratched up plastic glass lenses. WoW! I can see thru them again! That stuff filled in the scratches. Next stop is an old CD that has scratches...will keep everyone posted...

 

I hope you mean eyeglass lenses and not contacts!

 

Haha, I'm sure he meant his specs...

 

Cool makes sense...Z5 is synthetic based component.
