The answer is as always yes and no! Yes, if the patient has some safety frames, in good condition, which they may wish to use as a spare pair of spectacles. No if the patient requires the article to still be ‘safety spectacles’. Once a safety appliance has been tampered with – to whatever degree, they are no longer safety spectacles and the patient has no protection in law if an accident occurs. This is a fact you may like to remind your patients of when they pull off the side shields because they look unsightly!
Think very carefully before you do anything to a safety appliance, even a replacement screw could invalidate the appliance. The obvious question though is why anyone would want to reglaze a safety frame? They are functional, rarely attractive or comfortable and inexpensive to replace the whole item. Why take a risk?
