2) color shifting flake formed in step 1) is put in advance in the die cavity of injection forming mold of eyeglass, and be positioned at eyeglass Lateral surface position;
3) expecting to be injected in die cavity by the PC of molten condition, before not yet solidification, PC material is in the high temperature of 260 ~ 280 DEG C, utilizes This high temperature of 260 ~ 280 DEG C, PC material combines with color shifting flake, after curing molding, obtains the color-changing lens of multiple structure.
Preferably, in step 1), described sensitization discoloration material is to be folded between ground floor PC film and second layer PC film Membrane structure, or, described sensitization discoloration material is the coating structure being sprayed between ground floor PC film and second layer PC film.
Preferably, in step 1), described sensitization discoloration material is ultraviolet photosensitive color-changing material.
Preferably, in step 1), the thickness of described ground floor PC film and second layer PC film is between 0.1mm-0.5mm.
Preferably, in step 1), described sensitization discoloration material is placed between ground floor PC film and second layer PC film and passes through After optical cement is mutually cementing, carry out drying curved sizing.Certainly, by optical cement mutually cementing after before carry out drying curved sizing, being also can Row.
A kind of color-changing lens manufactured by described method, including eyeglass and the color shifting flake that is incorporated into eyeglass lateral surface, its Being characterised by, described color shifting flake is for being placed between ground floor PC film and second layer PC film by sensitization discoloration material and passing through optics The color shifting flake of the four-layer structure that glue is mutually cementing.Ground floor PC film is one layer, and second layer PC film is one layer, sensitization discoloration material Material is one layer, and optical cement is one layer, totally four layers.
Preferably, described sensitization discoloration material is the membrane structure being folded between ground floor PC film and second layer PC film, Or, described sensitization discoloration material is the coating structure being sprayed between ground floor PC film and second layer PC film.
Preferably, described sensitization discoloration material is ultraviolet photosensitive color-changing material.
Preferably, the thickness of described ground floor PC film and second layer PC film is between 0.1mm-0.5mm.
Wherein, described eyeglass is helmet glasses lens or skiing eyeglass, or other similar eyeglasses.
Preferably as the first style, the two ends of described helmet glasses lens are provided with installing hole, and the inner side of this installing hole is flat Slipped Clove Hitch structure, described color shifting flake is completely covered combination with the lateral surface of helmet glasses lens.
Preferably as the second style, the two ends of described helmet glasses lens are provided with installing hole, and the inner side of this installing hole is convex The adjustment structure risen, described color shifting flake is completely covered combination with the lateral surface of helmet glasses lens.
The invention have the advantages that and first sensitization discoloration material is placed between ground floor PC film and second layer PC film and leads to Cross optical cement mutually cementing formation color shifting flake, the most again by the way of in-mould injection molding, make PC eyeglass at curing molding During, utilize high temperature to combine with color shifting flake, form multi-layer colour-changing eyeglass, such color-changing lens, layer and layer it Between be close to be Construction integration, be difficult to get loose, reliable and stable.It is additionally, since ground floor PC film with second layer PC film by sensitization discoloration Material protection is in centre, even if exposing to the sun and rain, also will not impact sensitization discoloration material, thus its sensitization discoloration effect energy Enough keep for a long time.It can be widely applied to helmet glasses lens, skiing eyeglass etc. needs on the eyeglass of sensitization discoloration effect.
Explanation and detailed description of the invention below in conjunction with the accompanying drawings, the invention will be further described.
