Abstract
Data are presented from two field studies on the collision injuries which result from contact with tempered glass and 0.030 in (0.76 mm) high penetration resistant (HPR) laminated glass windshields. Two sets of similar automobile collisions are analysed. The frequency and severity of injury from the windshield are given for each set of collision. Comparisons are made on the basis of vehicle damage and equivalent impact speeds. Examples of the mechanisms of injury for the two types of glass are outlined. Eye injuries from the two types of windshields are discussed, together with the effect on the injury mechanisms when the windshield becomes detached during the collision.
