Chompers Strikes Again

At first it was just annoying, having to wrestle them out of her grasp, but now it's getting dangerous.  Becca loves to rip the glasses off anyone who comes close enough, which typically means Rich and me.  I've been trying to make sure she can't pinch her fingers/tongue in the hinges, but now there's a new problem.  

After taking them back this morning I found three new scratches, all exactly the same, and exactly the size of her tooth, on my left lens.  

It does give her a nice, intellectual look, though.
