To protect dentists, physicians, their assistants and others from contamination from contact with blood, bodily fluids and the like of patients, a transparent shield extends from the forehead to below the mouth and partially around the sides of the face. The shield is supported spaced from the face by a visor extending forward from the forehead. The visor is supported by a band around the back of the head. The present invention fabricates the shield, visor and head bands from a single blank, suitably die cut, all interconnected. The combined shield, visor and head bands may be attached to a surgeon's cap or the head bands may be eliminated and the cap attached to the inner edge of the visor.
