Well not quite but they had a good try.
Unfortunately its more common than you think! Leave your spectacles on a chair or on a low table or surface at your peril. Several times a year dog loving patients visit VJ Hughes Opticians in Lostock Hall with the sorry remains of a badly chewed pair of spectacles.
What can I do? Well you can of course always leave them out of reach, perhaps keep them in a metal bodied case or when not on your face wear them on a spectacle chain around your neck.
If this happens to you, its worth checking out your home insurance you may be covered for a replacement.
