Easily marred - Firefield Shooting Glasses

I ordered my glasses in January. They have been used several times with the yellow and amber lenses. I went to put the clear lenses in the glasses and they are marred and scratched from simply being in the glasses case, in the pouch for the spare lenses and still in the original plastic. Not a very comforting testament for a lens that's supposed to protect your eyes on a shooting range.
