Problems solved by technology

[0007] However, the above-described existing lens fixing devices for rimless spectacles have a disadvantage in that the fastening body is only molded from a soft or hard synthetic resin.
Specifically, in the case where the fastening body is made of soft synthetic resin, although there is an advantage of improving the bushing, eliminating the gap between the lens and the screw, and preventing the lens from shaking and the screw from loosening unintentionally, there are still disadvantages, that is, in the As the part of the nut, the fastening body is exposed to the inner surface of the lens. The internal thread of the fastening body is easily crushed by the tightening force of the screw, so the fastening body cannot normally play the role of a nut
[0008] On the contrary, when the fastening body is made of hard synthetic resin, although the internal thread of the fastening body is not easy to be crushed, and the fastening body itself does not expand due to the tightening force of the screw, the possibility of forming a gap between the lens and the screw increased
Therefore, the lens is likely to shake and it is difficult to provide a strong fastening force
[0009] Also, in existing rimless eyeglass lens fixing devices, the fastening body is molded from only one soft and hard synthetic resin as described above, and synthetic resin has an inherent defect that it tends to be too soft in summer and hard in winter
Due to the fact that over time the synthetic resin alternates between being too soft and too hard, the screws can loosen in the fastening body and the possibility of the lens shaking relative to the bridge or the temple is further increased
