In addition, the top frame member has the elastic deformability required to insert the lens. In a further embodiment of the invention, the temples may be curved inwardly from the upper frame member when not worn, and optionally overlap in the end regions. This avoids the need for a hinge with separate components so that cost-effective production can be achieved at the same time and at the same time the eyeglasses are securely fitted to the user's head due to the pre-tension. In addition, advantageously, the fastening device can be provided with at least two hook-like projections and a hook projection. The fishing-like projections are located on the top frame members on either side of the nose recess and are hooked to the edges of the lens. The hook projection 2 is formed on a vertical extension of the top frame member located in the nose region and is engageable within the nose recess of the lens. The lens in this example advantageously has a shaped recess at the upper edge, the u-shaped recess being sized such that the U-shaped recess encloses the projection of the hook-like projection extending from the top frame member in a form-fitting manner The lateral edges of the recesses 6 M304038 are then hooked onto the laterally extending portions of the forward end of the raised portion. The manner of connecting the lens and the top frame member described above is not only advantageous from a production point of view, but also has a very significant advantage for safety glasses, that is, the lens has a certain amount of clearance with respect to the top frame member, thereby 'Can absorb the energy of the particles that hit the outside of the lens. Therefore, such glasses satisfy the requirements relating to the impact strength according to the European standard 166 166F-impact (speed) 45 m/sec. The fastening means may also comprise a projection formed in the region of the lateral outer edge of the lens 10 formed on the top frame member, the projection being hooked onto the laterally upward edge of the lens in the inserted state of the lens. In this example, the lens is advantageously provided with a recess in the region of the lateral projection of the top frame member, the recess corresponding to the projection in a form-fitting manner. The laterally defining walls of the 15 u-shaped recess may extend in a direction perpendicular to the plane of the face so that it can be easily removed from the mold during the injection molding process of the lens. Advantageously, the nose bridge and temple ends are made of a softer plastic by two-component countercurrent injection molding to enhance wearing comfort. This production method 20 allows the temples and the frame to be integrated while the hardness in the respective regions still meets the requirements. The cross section of the temple is box-shaped, so that the height is obviously greater than the depth, so that on the one hand, sufficient rigidity can be obtained, and on the other hand, the glasses can be inwardly bent, 180, so that the glasses can be stored in the glasses case or Put it in the mouth of the mouth 7 M3 0403 8 for safekeeping. The respective cross-sectional shape of the frame or temple is varied at different locations so that, for example, within the "hinged region", i.e. in the lateral region of the lens, a sufficiently high flexibility for bending the temple is obtained. The present invention also relates to a method for securing an integral lens to an integral frame 5 frame member having lateral hook-like projections in the nasal region, hook projections in the nasal region, and two a lateral projection hooked to the outer edge of the lens, in order to secure the lens to the frame member, the lens is curved into an arc to reduce the width of the lens and push the outer edge of the lens into the lateral projection Then, the lens is oscillated to be hooked on the hook-like projection located laterally of the 10 nasal region, and finally the hook projection is engaged in the region of the nasal recess of the lens.
