Spectacles, having the following characteristics: 1.1 two lenses (1, 2); 1.2 a rigid or flexible frame having a frame part (5.1, 5.2) extending at the upper or lower lens edge of each lens and having a nose bridge located between the two frame parts (5.1, 5.2), a temple (3, 4) hinged at each end of the frame by means of a hinge (7.1, 7.2); 1.3 associated with each lens (1, 2) is a plastic thread which wraps around at least part of the periphery of the respective lens (1, 2), while resting against the lens edge; 1.4 each end of the respective plastic thread is connected to the frame; 1.5 each connection point is shaped as follows: the end of the single plastic thread forms a loop which wraps around a frame part (5.1, 5.2); the two longitudinal sections (8.1, 8.3) of the end section forming the loops and extending parallel to one another are passed together through the single longitudinal bore of a sleeve, and are thereby enclosed by the sleeve; characterized by the following features: 1.6 the sleeve tightly encloses the two length sections (8.1, 8.3) in such a way that the adjusted position of the sleeve relative to the plastic thread remains unchanged, wherein an independent displacement of the sleeve remains prevented by the friction due to the tight fit, but the tension of the threads wrapping around the lenses can be freely selected by displacing the length sections relative to each other and/or by displacing the sleeve on the length sections. 1.1 two lenses (1, 2); 1.2 a rigid or flexible frame having a frame part (5.1, 5.2) extending at the upper or lower lens edge of each lens and having a nose bridge located between the two frame parts (5.1, 5.2), a temple (3, 4) hinged at each end of the frame by means of a hinge (7.1, 7.2); 1.3 associated with each lens (1, 2) is a plastic thread which wraps around at least part of the periphery of the respective lens (1, 2), while resting against the lens edge; 1.4 each end of the respective plastic thread is connected to the frame; 1.5 each connection point is shaped as follows: the end of the single plastic thread forms a loop which wraps around a frame part (5.1, 5.2); the two longitudinal sections (8.1, 8.3) of the end section forming the loops and extending parallel to one another are passed together through the single longitudinal bore of a sleeve, and are thereby enclosed by the sleeve; characterized by the following features: the end of the single plastic thread forms a loop which wraps around a frame part (5.1, 5.2); the two longitudinal sections (8.1, 8.3) of the end section forming the loops and extending parallel to one another are passed together through the single longitudinal bore of a sleeve, and are thereby enclosed by the sleeve; characterized by the following features: 1.6 the sleeve tightly encloses the two length sections (8.1, 8.3) in such a way that the adjusted position of the sleeve relative to the plastic thread remains unchanged, wherein an independent displacement of the sleeve remains prevented by the friction due to the tight fit, but the tension of the threads wrapping around the lenses can be freely selected by displacing the length sections relative to each other and/or by displacing the sleeve on the length sections.
