A device (10) for clamping a lens (11) to a spectacle frame (12) comprises a bridge (16), which is rotatable about a pin (19) fixed to the body of the frontal frame or to the nose pad carrying element of the spectacle, said bridge being provided with two opposite ends relative to said pin, of which: a first end (27) is provided with a thread suitable for cooperating with a screw (26) which is suitable for causing the rotation movement of the bridge about said pin; and the second end (28) directly cooperates with the lens, by exerting a force on the surface of said lens, said force keeping the lens pressed against a conjugate element (22, 24) which is present on the body of the frontal frame and/or of the nose pad carrying element.
A device for clamping a lens to at least one of a frontal frame or to a nose pad carrying element of a spectacle, comprising a bridge rotatable about a fixed pin related to at least one of said frontal frame or nose pad carrying element, one end of said bridge having first means suitable for cooperating with the surface of said lens to clamp between said one end and the body of at least one of said frontal frame or nose pad carrying element, and the other end of said bridge having second means suitable for controlling the rotation movement of the bridge about said fixed pin to achieve the clamping and the release of said lens.
A device according to any of the preceding claims, wherein the body of said frontal frame and/or nose pad carrying element is provided with at least a means suitable for constituting a support for said lens.
