With traditional filtering blue light ophthalmic lens product or Technical comparing, the utility model has the following advantages:
1, at two surface coatings of lens matrix layer; namely blu-ray reflection rete is electroplate with at its front surface; and be coated with blue light antireflective coating in surface electrical thereafter; make to reduce blue light through eyeglass from the high energy blue light the light of front surface incidence by reflex; and the high energy blue light in the light of rear surface incidence enters eyes by anti-reflection effect minimizing blu-ray reflection; thus effectively filtering high energy has phototoxic specific wavelength blue light, protection eyes retina neurocyte.
2, two surface coating does not change the original color of lens matrix layer, does not produce aberration.
3, two surface coating and other retes combinationally use, and not obviously affect eyeglass overall light transmittance.
4, two surface coating and the direct strong bonded of other retes are at lens surface, without the need to extra pad pasting, and Portable durable.
5, eyeglass temperature change will be caused to cause human eye uncomfortable because of the absorption of eyeglass.

Embodiment
Below in conjunction with the drawings and specific embodiments, content of the present utility model is described in further details.
Embodiment one
The two surface coating structure of resin lens of energy filtering blue light, its high energy shortwave blue light mainly for wavelength 415nm-455nm carries out filtering.The two surface coating structure of this resin lens be use vacuum negative ion electrospray coating technology by pair surperficial before and after lens matrix layer (i.e. resin lens) while wearing (front surface be away from the lens surface of eyes), plates the Material selec-tion sexual reflex of attached certain thickness specific refractive index or the principle of anti-reflection specific wavelength light wave.Particularly, under temperature T=100 celsius temperature environment, select titanium dioxide or the zirconia material of refractive index n=1.38, the titanium dioxide of energy selective reflecting specific wavelength 415nm-455nm blue light or zirconia material Direct Electroplating are sticked to resin lens front surface, form blu-ray reflection rete, controlled the thickness of blu-ray reflection rete by regulation time, with reference to reflective coating thickness equations (d=enters/2n), blu-ray reflection thicknesses of layers is preferably 150nm-164nm.Equally, under temperature T=100 celsius temperature environment, can Selective long-range DEPT specific wavelength 415nm-455nm blue light through titanium dioxide or zirconia material Direct Electroplating stick to resin lens rear surface, form blue light antireflective coating, in like manner, with reference to antireflective coating thickness equations (d=enters/4n), the thickness of blue light antireflective coating is preferably 75nm-82nm.Like this by the selectively acting of two electroplating surface rete, lens front surface reduces blue light through eyeglass by reflex, and rear surface is reduced blu-ray reflection by anti-reflection effect and entered eyes.Can reach and effectively block the blue light transmissive function of lens matrix layer, and then reduce the effective luminous flux that blue light incides human eye retina, protection eye retina neurocyte is not by study of blue light injury.
Embodiment two
Please refer to shown in Fig. 1, two surface vacuum negative ion is electroplated conventional other retes adhered to of blu-ray reflection rete and blue light antireflective coating technology and resin lens and is combinationally used by it, other retes so-called, all be stained with in the front and rear surfaces of the lens matrix layer 1 of resin lens to add hard membrane layer and common antireflective coating (also known as antireflection film layer), wherein, the effect adding hard membrane layer is the hardness and the wearing quality that improve lens matrix layer 1, it can adopt vapour deposition method, sputtering method, the modes such as vapour deposition process plate the front and rear surfaces investing lens matrix layer 1, the effect of common antireflective coating is the transmitance (minimizing emissivity) promoting general visible ray, it also can pass through vapour deposition method, the modes such as sputtering method plate the outside surface investing and add hard membrane layer.Particularly, attached antireflective coating 4 is plated again after the front surface of lens matrix layer 1 first plates additional hard membrane layer 2, attached antireflective coating 5 is plated again after additional hard membrane layer 3 is first plated in the rear surface of lens matrix layer 1, and blu-ray reflection rete 6 and blue light antireflective coating 7 all plate the outside surface investing antireflective coating 4 and the attached antireflective coating 5 of plating respectively by two surface vacuum negative ion electrospray coating technology, material and the correlation parameter of blu-ray reflection rete 6 and blue light antireflective coating 7 can be identical with embodiment one.
Its principle of work is as shown in Figure 2:
From the light of lens front surface incidence first through blu-ray reflection rete 6 (shown in arrow 11 direction), according to the correlation parameter of blu-ray reflection rete 6, the high energy shortwave blue light of light medium wavelength 415nm-455nm is reflected away through arrow 31 direction by blu-ray reflection rete 6, the light of its commplementary wave length again through antireflective coating 4, add hard membrane layer 2, lens matrix layer 1, add hard membrane layer 3, enter human eye 8 (shown in arrow 12 direction) after antireflective coating 5 and blue light antireflective coating 7, process according to this, the high energy blue light in the light of lens front surface incidence is by filtering.
And from the light of lens posterior surface incidence first through blue light antireflective coating 7 (shown in arrow 21 direction), according to the correlation parameter of blue light antireflective coating 7, the high energy shortwave blue light of light medium wavelength 415nm-455nm increases transmitance through blue light antireflective coating 7, then successively antireflective coating 5, add hard membrane layer 3, lens matrix layer 1, add hard membrane layer 2, antireflective coating 4 and blu-ray reflection rete 6 (arrow 22 direction) be through eyeglass, process according to this, the high energy blue light in the light of lens posterior surface incidence also fails to enter human eye 8.
Above-listed detailed description is illustrating for the utility model possible embodiments, and this embodiment is also not used to limit the scope of the claims of the present utility model, does not allly depart from the equivalence that the utility model does and implements or change, and all should be contained in the scope of the claims of this case.
