In addition, the fixture of the eyeglass lens 3 to which the polarizing film 4 of the present invention is attached has the effect of preventing product defects from occurring by uniformly combining the polarizing film 4 with the eyeglass lens.

[0031] With reference to the attached schematic diagram of a desired embodiment of the present invention, it is explained so as to be easily carried out by a person having ordinary knowledge in the field.

[0032] In the present invention, the eyeglass lens 1 with the polarizing film 4 is prepolymerized at 15-60° C., the lens formed on the upper layer of the polarizing film 4 is in a gel state, and then polymerized at 25-120° C. to produce a polarized lens.

[0033] Thus, when the eyeglass lens 3 with the polarizing film 4 attached thereto is heated at 120° C. for about 5 hours during the heat treatment process, the present invention compresses and fixes the periphery of the eyeglass lens 3 with the polarizing film 4 attached thereto, and is composed of a fixing fixture.

[0034] The lower fixing part 1 of the annular structure is supported by inserting the eyeglass lens with the polarizing film 4 attached thereto, the lower fixing part 1 is inserted into the inner side of the fixing part, but forms an inclined surface so that the thickness becomes thinner as the thickness goes into the lower part, and the thickness of the end part 7 is thinner than the inclined plane, so that the polarizing film 4 is attached to the eyeglass lens 3 in the form of supporting only the edge of the upper fixing part 5,

[0035] A fixing device 8 is inserted into a connecting hole 2 formed at one side of the lower fixing part 1 and fixes the upper fixing part 5 .

[0036] Embodiment 2:

[0037] This embodiment provides an eyeglass lens clamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0038] The lower fixing part 1 is a lower part composed of an open ring of an upper part and a lower part, and a protruding support platform 9 is formed on the inner bottom surface. The eyeglass lens 3 with a polarizing film 4 attached inside is inserted, and the frame of the eyeglass lens 3 with the polarizing film 4 attached to the support platform 9 is fixed.

[0039] The support platform 9 supports and fixes the lower portion of the eyeglass lens, and may be formed on the entire lower fixing portion 1 or protrude from the lower fixing portion 1 at intervals.

[0040] The fixing device 8 is fixed by inserting into the connecting hole 2. The fixing device 8 is a butterfly bolt with a screw-shaped outer peripheral surface, which is inserted into the coupling ball. The lower fixing part 1 and the upper fixing part 5 are stable and easy to bond.

[0041] The upper fixing part 5 is composed of the open loop form of the upper and lower parts of the lower fixing part 1, and is combined with the lower fixing part 1 to press the periphery of the eyeglass lens with the polarizing film 4 attached and fix the upper part of the upper part, inserted into the inner side of the lower fixing part, and its size corresponds to the inner size of the lower fixing part, the thickness of the upper part is constant, the thickness of the lower part becomes thinner toward the bottom to form an inclined surface 6, and the end 7 is made of a thickness thinner than the inclined surface 6.

[0042] The end of the upper fixing part 5 is thinned to compress only the edge of the eyeglass lens 3 attached with the polarizing film 4 , and the thickness of the upper fixing part 5 along the inclined surface 6 is thickened and provides sufficient fixing force to fix the eyeglass lens 3 attached with the polarizing film 4 .

[0043] The lower end (bottom) of the upper fixing part 5 is thinned to minimize the contact with the polarizing film 4, so that a large amount of heat is exposed to the polarizing film during the heat treatment process, thereby promoting the bonding of the polarizing film 4 and the lens, and the upper part is formed thick enough to enable it to withstand the strong pressure in the lower fixing part 1.

[0044] The lower fixing part 1 and the upper fixing part 5 are frames made of a metal material, and the surface is hard and does not rust, and it is made of a material that can maintain its shape even at high temperatures.

[0045] The lower fixing part 1 of the present invention is inserted into the eyeglass lens with the polarizing film 4 attached, and the upper fixing part is inserted into the upper part thereof. The eyeglass lens 3 to which the polarizing film 4 is attached is pressed by the upper fixing part, but the polarizing film 4 is attached to the eyeglass lens 3, and only the edge of the attached eyeglass lens 3 is inserted through the connecting hole 2 of the lower fixing part to press the upper fixing part, and the polarizing film 4 will fix and support the eyeglass lens 3 connected to the accessory.

[0046] The interval between the upper and lower fixing parts 1 is adjusted according to the thickness of the eyeglass lens 3 to which the polarizing film 4 is attached, and the fixing device 8 is fixed together with it.

[0047] The polarizing film 4 is exposed to a temperature of 100°C or higher when exposed to the grains, so that the existing polarizing film 4 is heat-treated at 95-100°C, and when the polarizing film 4 is attached to the eyeglass lens 3, the polarizing film 4 is not bent, but in the present invention, the eyeglass lens 3 to which the polarizing film 4 is attached is heat-treated at above 100°C and is fixed on the eyeglass lens 3 to which the polarizing film 4 is fixed, so that the polarizing film 4 and the eyeglass lens 3 can be evenly bonded.

[0048] In the present invention, the polarizing film is attached to the light-collecting surface of the eyeglass lens 3 and to the other side of the support platform 9 fixed to the lower fixing part 1 .

[0049] The fixture for fixing the spectacle lens with the polarizing film 4 allows the spectacle lens to be heat treated at an appropriate temperature so that it can be completely molded and formed into a polarized lens.

[0050] Therefore, the eyeglass lens 3 with the polarizing film 4 fixed is inserted into the annular lower fixing part 1 formed on the inner bottom surface of the eyeglass lens 3, and the glass lens is connected to the side of the lower fixing part 1 from the upper part of the eyeglass lens 3 by the fixing device 8, and the fixing part of the upper fixing part 5 is thinly formed to fix the eyeglass lens to which the polarizing film is attached, but only compresses the edge, and as the thickness becomes thicker toward the upper part, sufficient fixation is provided to make the polarizing film 4 completely bonded to the eyeglass lens, so that the polarizing film 4 is exposed to high temperature for a long time during the heat treatment process, which has the effect of preventing the polarizing film 4 from bending.

[0051] In addition, the clamp fixes the eyeglass lens 3 to which the polarizing film 4 of the present invention is attached, and has the function of preventing product defects from occurring by uniformly combining the polarizing film 4 with the eyeglass lens 3 .
