are you sure that something else could not have done it and you just didn't see it? 
Positive on that.  I checked them in some light before I cleaned and it wasn't there. 
 
Are you 100% sure there was no dirt on the bag? Where has the bag been in the last 2 weeks? 
Can't say I'm positive, but I check it all over before I used the bag.  Its one of many that I have sitting in a drawer in my dresser, so it should be dust free. 
 
maybe the scratch was caused when u took it out of the frame 
Negative.  I haven't changed the lenses.  I took the scratched one out to inspect the scratch, but thats the only time I've had a lens out. 
 
Oh well, no big deal.  I'll just get some new ones at some point. 
 
Thank everyone
