Description
Technical field
It is a kind of 1.56 refractive index plated film and the double anti-indigo plants of base material specifically the present invention relates to eyeglass production technical field
Purple light eyeglass.
Background technology
Ultraviolet can injure eyes and be well known, but you may know that, can be to eye except black lights such as ultraviolets in light
Eyeball damages outer, it is seen that the blue violet light in light can also be damaged to eyes.Blue violet light is closest to ultraviolet and involves energy
Highest light is measured, blueness is presented between 400~500nm in wavelength in human eye sense organ.Long contact blue violet light equally can to regarding
Nethike embrane causes damage, and severe patient can cause visual impairment, triggers ARM, it is possible that blood-shot eye illness, eye is done, eye is puckery, eyesight
Obscure, asthenopia, the symptom such as head, back, shoulder and cervical vertebra ache.
Why blue violet light can cause so big injury to eyesIts basic reason is exactly short wavelength light and long glistening light of waves phase
Than being easier to scatter, the scattering of light refers to when medium of the light beam by homogeneous transparent, is difficult to see that light from side, but work as
When light beam is by inhomogeneous medium, from all directions it can be seen that light, this is that the inhomogeneities of medium causes light towards four sides
The result scattered from all directions.It can think that clear sky becomes misty when such as looking beyond, very dazzling, can't keep one's eyes open eyeball, this
Scattering is caused.The dazzling halation in sun periphery is also the result of light scattering, scattering produced by dazzle be cause it is dazzling,
The dry and astringent basic reason of flicker, eyes.
With the application of the progress and development, especially 3G network of society, computer display screen, smart mobile phone, tablet personal computer
It is widely used now Deng digital product, these digital products can all give out substantial amounts of blue violet light.Long Term Contact high-energy
Blue violet light easily makes us producing dizziness, and eyes are damaged, and the probability of ARM occurs in increase, and infringement is regarded
Power.One, the U.S. 2012 year is shown with regard to adult using the research report of digital product：4 are had daily for each person more than 80%
~6 hours even longer time used digital product.Photograph, image, word, animation etc. are from morning to night closely watched, it is right
Eyes cause certain pressure.Just once there is blood-shot eye illness in part respondent, and eye is done, and eye is puckery, eye-blurred, asthenopia, head, ridge
The symptoms such as the back of the body, shoulder and cervical vertebra ache.
In recent years, the patent blocked of blue violet light is carried out by Resin Absorbent technology it is enough, such as：Chinese patent
A kind of manufacture method of anti-blue violet light resin lens of CN103465418A and the product development anti-blue violet light eyeglass of a base material
Manufacture method.It is referred to as base material anti-blue light technology in ophthalmic len industry.The patent that blue violet light is blocked is carried out by way of plated film
Also it is a lot, a kind of anti-blue violet light eyeglass that such as a kind of anti-blue violet light resin lens of plated films of Chinese patent 203519943U are provided, to the greatest extent
Pipe can block 10% or so, but the emissivity of its eyeglass outer surface reaches 3%~4%, it is easy to cause during wearing
Ghost image situation.It is referred to as film layer anti-blue light technology in ophthalmic len industry.Whether base material anti-blue light technology and film layer anti-blue light
Technology has its merits and demerits, so far, surface is not invented also both technologies are carried out into effective integration.The mesh of the application
Be solve prior art in the presence of above mentioned problem, combine the advantage of plated film anti-blue light and the advantage of base material anti-blue light,
The application is related to a kind of 1.56 refractive index plated film and the double anti-blue violet light eyeglasses of base material, it is characterised in that：Eyeglass is in resin formula
Introduce royal purple light absorber benzotriazole, group-substituted acrylonitrile, benzophenone one or more kinds of, royal purple x ray fluoroscopy x score
Wei not wave band 280nm~380nm, transmittance≤0.5%；380nm~420nm≤20%；Lens front surface is plated in plated film
Film into reflectivity >=15% with 380nm~420nm film layer, by lens posterior surface plated film into 380nm~450nm's
The film layer of reflectivity≤4%.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of 1.56 refractive index plated film and the double anti-indigo plants of base material
Purple light eyeglass.
The purpose of the present invention is achieved through the following technical solutions：
A kind of double anti-blue violet light eyeglasses of 1.56 refractive index plated films and base material, introduce royal purple light absorbs in the raw material of eyeglass
Agent, mass fraction of the royal purple light absorber in Raw materials for lenses is 0.1~5%.
Described royal purple light absorber is BTA, substituted acrylonitrile, benzophenone are one or more kinds of,
BTA, substituted acrylonitrile, benzophenone include 2'- (the 2'- hydroxyl -3'- tert-butyl group -5'- aminomethyl phenyls) -5-
Chlorobenzotriazole or or 2- (2'- hydroxyl -5'- t-octyls phenyl) BTAs or ESCALOL 567 or 2,
2'- dimethyl -4- methylamino benzophenone.
A kind of double anti-blue violet light eyeglasses of 1.56 refractive index plated films and base material, in plated film by lens front surface plated film into
The film layer of 380nm~420nm reflectivity >=15%, by lens posterior surface plated film into the reflectivity with 380nm~450nm≤
4% film layer.
The material of described film layer is silica, zirconium oxide, alundum (Al2O3), tin indium oxide and fluoride.Fluoride exists
One layer of the outermost of film layer, plated film is carried out using a kind of in electron gun and main steaming two ways.
The processing method of the double anti-blue violet light eyeglasses of a kind of 1.56 refractive index plated film and base material, its step is：
After the raw material of eyeglass is filtered with 0.5 μm of filter disc, it is poured into glass mold, is put into baking oven, under
The program curing in face carries out Raolical polymerizable.

Spectrogram is as shown in Figure 2, you can obtain 1.56 refractive index plated films and the double anti-blue violet light eyeglasses of base material.It is simple and convenient, and impart mirror
The excellent performance of piece.The score of royal purple x ray fluoroscopy x Wei not wave band 280nm~380nm, transmittance≤0.5%；380nm~420nm≤
20%；Film layer in plated film by lens front surface plated film into reflectivity >=15% with 380nm~420nm, after eyeglass
Film layer of the surface coating into reflectivity≤4% with 380nm~450nm.
The raw material of eyeglass mainly includes styrene, benzyl methacrylate, Isosorbide-5-Nitrae butanediol dimethylacrylate, double
The acrylate of pentaerythrite six, benzyl acrylate, catalyst azodiisobutyronitrile, 2- (2'- hydroxyl -5'- t-octyls phenyl)
BTA, 2.6- toluene di-tert-butyl phenols and royal purple light absorber.
The program curing used, has taken into full account the heat release heat absorption problem of radical polymerization process, designed solidification
Curve, more ensure that the moulding process of eyeglass, it is ensured that fried mould is controlled below 1.5% from phenomenon is molded.
The acryl resin eyeglass with protection royal purple optical property according to obtained by production program, it is seen that x ray fluoroscopy x ratio is more than
Equal to 93%.
The impact strength of eyeglass may be up to 60kJ/M2, can assemble no-frame glasses.
Compared with prior art, the positive effect of the present invention is：
This kind of color-changing lens can be processed with conventional resin lens stiffened and anti-reflection membrane process, and the jail of film layer
Soundness can reach primary standard, so as to eliminate stiffened coating process complicated in eyeglass manufacturing process, saves processing cost, carries
The high quality of eyeglass.
