Abstract
Protective spectacles have a protective shield, fitted in the temple region, to protect the eyes from dust, etc., coming from the side. According to West German Industrial Standards, DIN, a predetermined degree of sealing must be maintained, according to the purpose of use, between it and the spectacle frame. Protective shields attached rigidly to the frame are cumbersome. The protective shield is firmly connected by its upper edge region to the associated spectacle earpiece. It is thus pivoted away together with the earpiece. Its forward edge seals with the spectacle frame with a predetermined degree of sealing. So that this is not impaired by adjustment of the inclination, the earpiece has a bending zone behind the protective shield. The inclination is adjusted by bending the earpiece. The invention may be used for protective spectacles in the industrial and private fields.
