Results of recent field accident studies in Europe show that toughened glass causes at least twice the amount of injury in comparison to High Penetration Resistant (HPR) laminated glass. This confirms previous and laboratory and field studies. Eye injury from toughened glass windscreens is a substantial problem reflected in the clinical literature from at least 12 countries. By contrast, countries which use HPR laminated glass report no incidence of eye injuries from the windscreen of any consequence.
