    "1. Rimless spectacles comprising two spectacle lenses, a bridge connected with both spectacle lenses, a first endpiece (8) connected with the one of the spectacle lenses (2) at a portion thereof facing away from the bridge, and a second endpiece connected with the other one of the spectacle lenses at a portion thereof facing away from the bridge, wherein, for connecting the bridge and/or the two endpieces with the respective spectacle lens (2), the latter has a first through-hole extending from the front side (4) to the rear side (6) thereof, and the bridge and/or each of the two endpieces has/have a contact portion (10) abutting on the front side or the rear side of the spectacle lens as well as a stud (16) integrally formed with the contact portion and being inserted into the first through-hole, characterized in that the first through-hole (22) has a non-circular cross-sectional profile, that the stud (16) has a non-circular cross-sectional profile conforming to the cross-sectional profile of the first through-hole, that in the stud and in the contact portion, a second through-hole (18) is formed, and that a pin (24) is inserted into the second through-hole, said pin having a head (28) which, with its lower side, abuts on the spectacle lens (2) on the side thereof facing away from the contact portion (10).",
    "2. Spectacles according to claim 1, characterized in that the contact portion (10) and the stud (16) comprise plastic material.",
    "3. Spectacles according to claim 1, characterized in that each of the conforming non-circular cross-sectional profiles of the first through-hole (22) and the stud (16) is a profile defined by two partly overlapping circles.",
    "4. Spectacles according to claim 1, characterized in that each of the conforming non-circular cross-sectional profiles of the first through-hole and the stud is a flat oval profile having straight long sides.",
    "5. Spectacles according to claim 1, characterized in that a transition fit is provided between the first through-hole (22) and the stud (16).",
    "6. Spectacles according to claim 1, characterized in that a clearance fit is provided between the first through-hole (22) and the stud (16).",
    "7. Spectacles according to claim 1, characterized in that the free front surface of the stud (16) runs flush with the side of the spectacle lens (2) facing away from the contact portion (10).",
    "8. Spectacles according to claim 1, characterized in that the pin is fixed in the second through-hole by a form-locking engagement.",
    "9. Spectacles according to claim 8, characterized in that the pin has an external thread.",
    "10. Spectacles according to claim 1, characterized in that the pin (24) is fixed in the second through-hole (18) by a force-locking engagement.",
    "11. Spectacles according to claim 1, characterized in that the pin (24) consists of plastic material.",
    "12. Spectacles according to claim 1, characterized in that the upper side of the head (28) of the pin (24) is lenticular.",
    "13. Spectacles according to claim 1, characterized in that the pin end facing away from the head (28) of the pin (24) runs flush with the surface of the contact portion (10) facing away from the spectacle lens (2).",
    "14. Spectacles according to claim 1, characterized in that the contact portion (10) is arranged on the front side (4) of the spectacle lens (2)."
