ば容易に取り外しが行える。In the present invention, the type of adhesive used to bond the plastic lens and the jig is not particularly limited. Epoxy-based, acrylic-based, silicone-based, instant adhesive and the like can be mentioned. A cyanoacrylate-based instant adhesive is preferably used. Many cyanoacrylate-based instant adhesives cause whitening in the vicinity of the bonded portion, but this is not a problem because it is almost washed by the dipping-type primer coating and / or the cleaning before the hard coating. In addition, since there is a type of whitening resistant type, it is preferable to use that type. Next, the shape of the jig is shown in FIG. Regarding the shape, it is preferable that the hard coat liquid does not form a liquid pool and the adhesion area with the lens is about 5 mm 2 or more, and other fine shapes are not particularly limited. The material of the jig may be plastic such as styrene resin, urethane resin, acrylic resin, diallyl carbonate resin, Teflon resin, or metal such as stainless steel. It is recommended to select an appropriate one in consideration of the ease of removal in relation to the adhesive and the tact time of the manufacturing line. The jig and the lens may be bonded together by applying an adhesive of about 0.1 cc depending on the bonding area and curing according to the curing method of the adhesive used. The cured lens with a jig is framed in a dedicated frame and washed to provide a primer coat layer and / or a hard coat layer. The hard coat agent used for forming the hard coat layer may be any silicon-based material. The reason why the silicone-based resin is used is that a hard coat layer that is harder than the melamine-based or acrylic-based resin can be obtained. If the hardness is not important, the melamine-based or acrylic-based resin may be used. After applying the hard coat agent, a hardening treatment is carried out by a method according to the hardening means of the hard coat agent, such as heat hardening, ultraviolet ray hardening, electron beam hardening, and the hard coat layer is formed on the surface of the plastic lens. After that, the jig is removed from the lens, but it can be easily removed if a cyanoacrylate-based instant adhesive is used as the adhesive.

Examples of the substance used for forming the antireflection film include metal, metal or metalloid oxides, fluorides and the like. Typical examples are metal oxides such as SiO 2 and ZrO 2 and fluorides such as MgF 2. is there. Examples of the method for forming a single-layer or multi-layer antireflection film include a vacuum deposition method, a sputtering method, an ion plating method, and an ion beam assist method.

Shed to. In the hard coat process, the in-house silicon hard coat agent NL70H was used as the hard coat liquid and the dipping method (pulling speed 100 cm / mi
n) was applied. The coated lens was heated at 90 ° C. for 30 minutes to cure the hard coat layer. The lens was taken out from the frame where the hard coat had been hardened, and the deformation, coating liquid sagging defect, scratch defect, and number of drops were examined. As a result, 5 deformations, 3 sagging defects, 2 scratch defects, and 4 drops occurred. .
