輪（渦論）が生じ、此の論が目障りになる。[Detailed description of the invention] In the conventional method of processing glasses lenses, the entire circumference was processed with bevels (except for special ones) and fitted into glasses frames, but with this method, the frames A strong ring (vortex) occurs around the entire circumference of the part that touches the frame, which becomes an eyesore.

PMV cutting is said to be effective in preventing this, but the vortex theory remains. It is said that it would be best to paint black enamel on top of it, but the black color would reflect extensively on the inside and outside sides. The present invention eliminates these drawbacks, suppresses the visible vortices as much as possible, and makes the lens brighter. To explain the processing method of the present invention according to the drawings, 1 in Fig. 1 is a plan view of a polished lens, and 2 in Fig. 1 is a plan view of a polished lens.

However, even if the lens has the same number of lenses, the thickness of the green part of the outer periphery of the lens will differ due to the difference in external dimensions and diameter of the lens, so it is necessary to select and change the sliding angle appropriately according to the size of the lens etc. be.

法で摺り更に全周研磨する。Generally, the minimum sliding angle is 90o or 130o.
If the angle is greater than o, the area of the effective lens may become too narrow, and considering the ease of processing, it is desirable that the maximum sliding angle be within the above angle. The object of the present invention is to process lenses for spectacles for myopia so as to minimize the occurrence of ring formation and to obtain a clear lens surface. Then polish the entire circumference. This is the first method. The second method is A3a~f, A4d~e, &
A winding angle is provided in the portions b to c, and the surfaces e to f are perpendicular to the surface of the lens (90 degrees), and the outer surfaces a to b and the inner surface c
-d are printed and further polished all around in the same manner as the first method. Third
As shown in 1 in Fig. 3, the angles are set in the parts A6a to d, and the planes b to c are at right angles (90 degrees) to the surface of the lens.
) The outer surfaces a to b and the inner surfaces c to d are rubbed in the same manner as in the first method, and then the entire circumference is polished.
以上の様な加工法を採用するとしンズに映る豪輪（渦論
）は完全に消去し本発明の目的を達成する事が出来る。By employing the processing method described above, it is possible to completely eliminate the vortices that appear on the lenses, thereby achieving the object of the present invention.
