Description
Technical field
The utility model belongs to portable data assistance screen light and endangers prevention and control field, and in particular to one kind is based on AG and prevents
The screen protective shield of blue light double effects.
Background technique
With mechanics of communication fast development, into the information age, various electronics and IT products are flooded in life,
Nowadays people are using the frequency of the portable products such as smart phone, plate, electric paper book, computer almost not from the journey of hand
Degree.But many people are not aware that, the use of the electronic products such as mobile phone are frequently very big to the harm of people's eyes.It is straight first
Dazzle is penetrated, improves blue segment wave band flux (the mainly flux of wavelength 450nm blue light) ratio of screen exit rays to enhance mobile phone
The color contrast and saturation degree of screen also increase the intensity of direct projection dazzle so that screen picture is apparent more bright-coloured bright,
The high energy shortwave blue light of followed by excessive high irregular frequency can penetrate our through retina of eyeglass, accelerate view
The pigment epithelial cell of film becomes feeble and die, and eventually leads to retinal photoreceptor cells and lacks nutrient and cause vision impairment or macular diseases
Etc. eye illnesses, seriously may cause blindness.Having multinomial medical research proves, the youth of the eye diseases such as cataract and maculopathy
The trend changed and generalized has direct relation, Chinese central television with the time of the portable electronic products such as modern's contact mobile phone
Platform also did special report with regard to harmfulness of the blue light to eyes.It is finally reflected glare, after indoor UV light projects on screen
Reflecting dazzle, to will cause sight screen uncomfortable, can't help furthering eyes between screen at a distance from, although screen-picture is to see clearly,
But the received blue light energy of eyes is more, bigger to the injury of eyes.Ophthalmologist, oculist appeals to reduce injury journey for protection eyes
Viewing distance more than half arm of frequency of use and holding of degree or reduction electronic product；Take the wound for reducing screen light
Harmful safeguard measure.
In the today for reading the screen epoch, the electronic products such as mobile phone have been fully immersed into the clothing, food, lodging and transportion -- basic necessities of life of people, reduce using and
It is unpractical for keeping the measures such as viewing distance.Screen blue light harm practical application preferably is reduced by one layer of protection screen of patch
In.In the market there are many kinds of the screen protection screen products of plastic and glass material, although there is certain anti-blue light effect, but still deposit
It is easy to fall off that dazzle, Anti Glare Coatings can not be eliminated in such as plastic protective film for plastics xanthochromia easy to aging and fuzzy, transparent glass protective film
With scratch and anti-blue light effect does not have a problems such as specific aim, awkward impression and frequent replacement is serious reduces people couple
The selection enthusiasm of screen products is protected in eyeshield, and therefore, market in urgent need has permanent anti-dazzle and filter blue light while a kind of novel
The screen protective shield new product of function, better meets needs of health of people and preparation method thereof.
Utility model content
The purpose of the utility model is to provide a kind of screen protective shield based on AG and anti-blue light double effects.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of screen protective shield based on AG and anti-blue light double effects, including base, the side of the base are anti-dazzle
Anti-blue light layer is arranged in light AG process layer, the other side, and the anti-blue light layer includes the internal layer and outer layer being successively connected with base, institute
Stating internal layer is titanium pentoxide layer, and outer layer is silicon dioxide layer, and middle layer, the middle layer are arranged between the internal layer and outer layer
For one layer or two in silicon dioxide layer, tantalum pentoxide layer, yttrium oxide layer, lanthana layer, scandium oxide layer, titanium pentoxide layer
Layer or more combination.
The anti-blue light layer further includes the adhesive layer being arranged between internal layer and base, and the adhesive layer is silica
Layer.
Every layer of thicknesses of layers for forming the adhesive layer of anti-blue light layer, internal layer, outer layer and middle layer is 30nm~150nm, and
The overall thickness of anti-blue light layer is 200~400nm.
The overall thickness of anti-blue light layer is 300nm.
The roughness of particles of AG process layer is 55 nm, and glossiness is 15Gu~50Gu, and reflectivity is 0.5%~3.0%.
In the present invention, anti-blue light layer is superimposed number with anti-blue light film layer to the filter effect of blue light and synchronizes increase, studies table
Bright, film layer number is less than 4 layers, and blue light interception rate is lower than 50%, unobvious to protection eye effect；Film layer number is more than 6 layers, and blue light blocks
The rate of cutting is more than 65%, though interception effect is good, light transmission rate is lower than 80%, excellent to guarantee visual comfort and protection eyes function
4-6 tunic layer is selected to be advisable.
Compared with prior art, the invention has the following advantages that
The light reflectance of the screen protective shield of the utility model is down to 3% hereinafter, and according to application field difference by 8.3%
Meet 450nm wavelength blue light interception rate arbitrarily to adjust within the scope of 40%-70%, and guarantees that light penetration will reach under normal watch
To 80% with first-class performance requirement, the optimal balance of the comfort of eyeshield effect and vision is realized.Simultaneously as anti-dazzle photosphere is straight
It connects and is etched in glass surface chemistry, rather than coating, inner face anti-blue light layer are fitted closely with screen, completely cut off atmospheric vapour and sweat
The erosion of liquid, thus the present invention realizes the persistence of anti-dazzle and filter blue light performance, effect never decays.
