DESCRIPTION OF THE PREFERRED EMBODIMENTS The manufacturing method of the present invention will be described below with reference to the drawings.

FIG. 1 shows a method of manufacturing a ring for eyeglass lenses. First, a synthetic resin plate material 1 such as PC acetyl is used.
The disk 2 is formed by cutting using a suitable means. The synthetic resin plate material 1 is preferably colored, but is not limited to this. Next, after the cut disc 2 is made vertical, the chuck 4 of the lathe 3 is bitten and fixed at a predetermined position on the outer periphery of the rear side 2a thereof, and then the outer periphery of the disc 2 is substantially centered from the front side. Up to a constant thickness is cut by the cutting tool 5, and in parallel with this work, the centering of the disk 2 is also performed.

Since the structure of the lathe 3 is well known in the prior art, and the chuck 4 and the bite 5 which are the auxiliary equipments of the lathe 3 are the same, detailed description of the lathe 3 and the auxiliary equipments thereof is omitted. To do.

Next, when the above-mentioned series of operations are completed, the disk 2 is removed from the chuck 4 and the front side 2b and the rear side 2a are removed.
In reverse, the front side 2b is again bitten by the chuck 4 and fixed. When this work is completed, the inside of the disk 2 is hollowed out by a cutting tool 5 with a predetermined wall thickness 7 left between the disk 2 and the outer circumference, whereby the disk 2 is formed as a hollow member 8.

Next, the inner peripheral surface 9 of the hollow member 8 is ground with another cutting tool 11 having continuous concavo-convex teeth 10, and the concavo-convex teeth provided on the other peripheral tool 9 on the inner peripheral surface 9. A continuous uneven strip portion 12 conforming to the shape of 10 is formed.

Thereafter, the hollow member 8 is removed from the chuck 4 and the columnar member 14 is fitted therein, and both of the hollow member 8 and the columnar member 14 fitted therein are mounted on the chuck 4 of the lathe 3. Bite and tighten again to fix. Then, the outer peripheral surface of the hollow member 8 is ground with the cutting tool 5 until the bottom portion 15 of the recessed streak portion 12a of the continuous recessed and projected streak portion 12 formed on the inner peripheral surface 9 of the hollow member 8 is removed to separate the protruding streak portion 12b. Then, a plurality of eyeglass rings 16 are formed.

Through the above steps, the spectacle lens ring 1
6 can be manufactured. Further, according to the above-described manufacturing method, since the manufacturing process is simple, the spectacle lens ring 16 can be manufactured at low cost.

The spectacle lens ring 16 thus manufactured is attached to the groove 22 on the peripheral surface of the lens 21 of the rimless spectacles 20 as shown in FIGS. -It is possible to meet the diversified demands of consumers by making the necessary upgrades. In addition, the ring 16 makes it appear that the periphery of the transparent lens 21 is colored, which gives a more luxurious impression.

Further, by attaching the ring to the groove portion 22 on the peripheral surface of the lens 21 of the rimless glasses 20, the strength of the lens 21 is increased and damage can be prevented.

In the method for manufacturing a ring for eyeglass lenses, the synthetic resin plate material 1 is cut to form the disc 2 in the first step. However, the disk 2 is not necessarily limited to this, and for example, a circle. , Synthetic resin rods such as squares cut into short pieces may be trimmed into a predetermined shape by the lathe 3, or block-shaped synthetic resin material may be trimmed into a predetermined shape by the lathe 3. .
