The anti-blue light no-coated lens is prepared by taking methacrylic acid polymer as a main body of the material and adopting core-shell transition metal oxide nano particles, aluminum oxide particles, silicon carbonate particles, ultraviolet light absorber and surfactant dispersed in the main body of the no-coated lens.
Description
Technical field
The present invention relates to the substrate of a kind of lens, be specifically related in a kind of anti-blue light lens use substrate.
Background technology
In prior art, the research of anti-blue light lens is like a raging fire, and especially as the development of Internet technology, the anti-radiation glasses including anti-blue light ultraviolet radiation preventing is used widely.Generally, it is seen that optical band is approximately the spectral region from the wavelength of 380 nanometers (nm) to the wavelength of 780nm.The part of about 380nm to about 500nm corresponds essentially to high energy blue light.The especially amphiblestroid infringement of human eye is very big by blue light, if the long-time exposure of human eye may result in serious ophthalmic diseases under blue light, and such as age-related maculopathy, seriously even result in human eye blind.But, health is but advantageous for for 465nm to the 495nm part in above-mentioned blue wave band, since relevant to human biological's cycle, it is possible to blood circulation promoting.What existing safety goggles against radiation filtered generally includes ultraviolet light and major part short-wave band visible ray.And prior art rarely has and retains the anti-blue light glasses higher than 465nm, its reason is in that at this wave band narrower, when filtering 450nm and more short wavelength, can't help just having filtered the blue light of more than 465nm.The high-reflecting film or the optical filter that use in existing anti-blue light glasses are generally all wide area type diaphragms, because Narrowband Spectral High-Reflectivity Filter Multilayers or the optical filter process when vacuum evaporation deposits is overflow long and complex, manufacturing cost is high.On the other hand, even if use narrow band pass filter, the harmful blue light come from lens front surface reflection is filtered, but the indirect light being derived from wearer rear then can reflex in the eye of eyeglass wearer in an identical manner, these arrival wearer's amphiblestroid harmful blue light luminous fluxes meetings are suitable with front incidence, cause blue light to injure wearer's eyes.
It is known that, in anti-harmful blue light eyeglass, front and rear surfaces can apply UV coating, in order to absorb UV light, also has the coating of some other functions, such as impact-resistant coating, wear-resistant coating, anti-reflection coating, antistatic coating, polarizing coating and anti-pollution layer and/or antifogging coating etc., and eyeglass this as a transparent substrate being made up of organic resin or glass, the material such as such as thermoplastic polymer is made.
The described thermoplastic for using in the substrate, such as (methyl) acrylate copolymer, polyethylene (methyl methacrylate) (PMMA), sulfo-(methyl) acrylic acid, polyvinyl butyral resin (PVB), Merlon (PC), polyurethane (PU), polyethylene (thioxanthamide), polyhydric alcohol allyl carbonate, Ethylene/vinyl acetate, also such as polyethylene terephthalate (PET) or polybutylene terephthalate (PBT), many episulfide compounds, polyepoxide, the copolymer of Merlon and polyester, the copolymer of cyclenes copolymer such as ethylene and norborene or the copolymer of ethylene and cyclopentadiene, and their combination etc..
In prior art, reduce blue light injury and increase the requirement of light transmittance and often can not get both, attending to one thing and lose sight of another, shifting, want to reduce blue light injury, it is necessary to sacrifice light transmittance as cost.Existing motion proposes at such as acrylic acid series substrate front and rear surfaces plated film, including antireflective coating, anti-reflection film etc., to reach anti-reflection effect while injuring at anti-blue light.Namely adopting the structure that this front and rear surfaces film system is different, front surface rete efficiently prevents the blue light injury to human eye, and rear surface rete increases the transmitance of eyeglass, reaches anti-reflection effect.
In prior art, the substrate of a lot of anti-blue light eyeglasses is that the organic coloring agent such as melanin, flavochrome is contaminated on doping or surface in lens substrate, it is achieved in harmful blue light and filter effect.But, organic dyestuff weatherability is poor.Additionally, anti-blue light eyeglasses most in prior art, substantially filter harmful high energy blue light, under permanent chromatic distortion, the colourity sensitivity of optic nerve can be reduced, have the risk causing color weakness or even achromatopsia.
Namely the problem that the present invention to study is to provide the substrate of such anti-blue light eyeglass, when being left out the antireflective film of evaporation, high-reflecting film etc. on substrate, make substrate itself can be effectively improved transmitance, colourity mildness and the eyeglass substrate of anti-harmful blue light.
Summary of the invention
In view of above-mentioned technical problem, the present invention provides a kind of anti-blue light glasses substrate, energy high efficiency filter harmful blue light and ultraviolet, and can be effectively improved transmitance and colourity mildness.
Concrete, the present invention provides a kind of anti-blue light glasses substrate, it is characterized in that, this substrate is by adopting the methacrylate polymer main body as material, and be scattered in the hud typed transition metal oxide nano-particles in described substrate body, alumina particulate, carbonic acid silicon particle, UV absorbent, surfactant are made；Wherein, hud typed transition metal oxide nano-particles, alumina particulate, carbonic acid silicon particle, UV absorbent, surfactant account for 1%-2%, 1%-3%, 1%-1.5%, 1%-4%, the 0.5%-1% of substrate gross weight respectively.
Anti-blue light glasses substrate described above, described hud typed transition metal oxide is Fe2O3。
Anti-blue light glasses substrate described above, described surfactant is polyvinyl pyrrolidone.
According to the present invention, when making described substrate, can be carried out as follows: first, methacrylate polymer is dissolved in solvent, obtain this polymer solution, as solvent, can be conventional organic solvent, then, hud typed transition metal oxide nano-particles, alumina particulate, carbonic acid silicon particle, UV absorbent, surfactant are filled in this solution according to said ratio, it is sufficiently stirred for dissolving, then passes through spin coating and obtain this substrate.
According to the present invention, owing to eyeglass substrate being doped with hud typed transition metal oxide (titanium dioxide, cobalt oxide and/or ferrum oxide) nano-particle, alumina particulate, carbonic acid silicon particle, substantially increase durability and light transmission and, have resistance for wavelength at harmful high energy blue light of 380-465nm scope.
