We had some cheap safety glasses at work that looked flimsy enough to be worthless. Don't know the brand, but it's the kind that are clear all over. We rigged up an air gun to shoot various things at them. The best hit we got was a phillips screwdriver right into the middle of the lens. It hit hard enough to break off one of the ear pieces (It was backed up by a board to give some resistence) but did not penetrate the lens. It left a small cross punched into the lens. Pretty impressive I thought.
