In the lens mounting hole 41 of the lens mounting table 40, a conventional spectacle lens (plastic material) is inserted and seated on the protruding end 30 inside the vapor deposition chamber, and then the coating material insertion hole of the coating material melting furnace ( 91) is filled with a far infrared antimicrobial coating agent, SiO ₂ and ZrO ₂ in order, the order of filling is a far infrared antimicrobial coating agent-SiO ₂ -ZrO ₂ -SiO ₂ -ZrO ₂ -SiO ₂ .

Next, close the door 21 and lock the locking device 23 and adjust the vacuum degree inside the vacuum deposition furnace 20 to 2x10 ^-5 Torr and turn on the halogen lamp 50 to heat about 100-120 degrees Celsius. Preheat for 3-4 minutes. After that, the halogen lamp is continuously turned on and the temperature inside the vacuum deposition furnace is always maintained at 100-120 degrees Celsius during the manufacturing process described below. When the temperature is maintained within this range, the deposition effect is best created. do.

As described above, moisture and gas contained in the above-described coating agent (coating agent) are discharged through oxidation of the halogen lamp to oxidize and extinguish, and moisture contained in the lens itself is also evaporated to obtain a good overall deposition effect. .

Next, the ion beam generator 60 is operated for about 2-4 minutes to etch the surface of the spectacle lens, which is an essential step to obtain stability and robustness of the deposited coating film.

Next, the operation of the ion beam generating device is stopped and at the same time the electron beam generating device 80 is operated to apply heat of about 1,200-1,400 degrees Celsius to fill the coating material filled in the coating material insertion hole 91 of the coating material melting furnace 90. The coating material is deposited on the bottom of the spectacle lens placed on the lens mount by evaporating at the same time as melting. First, after the deposition of the far-infrared antimicrobial coating agent is completed, the coating material melting furnace is rotated to make the second coating material SiO. The position of the coating material insertion hole filled with ₂ is moved to the upper part of the beam gun of the electron beam generator. Immediately, the second coating material, SiO _2, is melted and evaporated and deposited onto the far infrared antimicrobial coating layer.

However, the coating thickness of the indium oxide in the fourth embodiment is only a difference of 100 kPa and the difference that the oxygen etching process is applied. That is, in the fourth embodiment, the surface of the SiO ₂ coating layer already coated by supplying oxygen through the oxygen supply plate 61 on the Si0 ₂ coating layer prior to coating the indium oxide and operating the ion beam generator 60 at the same time. Oxygen etching is applied. This is to significantly improve the degree of deposition of indium oxide to maintain good heat resistance and durability.
