The blue-light-resistant protective film can be used for converting blue light into visible light in any other waveband so as to play a role in protecting eyes. The blue-light-resistant protective film includes seven layers: a film protective layer, an adhesive layer A, a scratch-resistant layer, a blue-light-resistant layer, a main film layer, an adhesive layer B and a stripping layer, wherein the adhesive layer B is arranged on the upper surface of the stripping layer of a substrate layer, the main film layer is arranged on the adhesive layer B, the blue-light-resistant layer is introduced to the main film layer, the scratch-resistant layer is introduced to the blue-light-resistant layer, the adhesive layer A is arranged on the scratch-resistant layer, and the film protective layer is arranged on the adhesive layer A. By using the blue-light-resistant protective film, the blue light can be isolated, the irritation of the blue light to eyes can be greatly reduced, the myopia can be controlled, and the eyes can be protected.
Description
Technical field
The present invention relates to a kind of protective membrane, be specifically related to a kind of anti-blue light protective membrane that prevents blue light injury eyes for display screens such as digital camera, mobile phone screen, computer screens.Protective membrane technique involved in the present invention is simple, can realize industrialization.
Background technology
Develop rapidly along with electronics technology, increasing people is using the electronic products such as computer, mobile phone, digital camera, daily life be unable to do without electronic product especially, consequent visual problems but highlights day by day, this phenomenon just in the teenager of life-time service electronic product, white collar obviously, but also more and more trend towards becoming younger and aging.WHOAi Yan association of World Health Organization announces: within 2006 to 2008, because of blue ray radiation, to cause every year the whole world to surpass 30000 people blind, and in the end of the year 2009, send orange early warning: " blue ray radiation to the mankind's potential recessive threat will considerably beyond Sudan red, trimeric cyanamide, SARS, H1N1 ".
Blue light is the important component part of visible ray, and nature itself does not have independent white light, after blue light and green glow, yellow light mix, presents white light.In the visible ray that send the electronic product fluorescent screens such as computer, mobile phone, digital camera, there is a large amount of irregular shortwave blue lights, the just high energy shortwave blue light between 360nm-500nm to eye injury maximum.It can directly penetrate cornea, and the retina in eyeground is damaged, and causes macular disease, and especially this interval of 450nm-460nm, injures maximum.
Blue light has had again fresh evidence to the injury of eyes in recent years.Because blue light can cause the death of cell by improving visual cell to the susceptibility of light and photooxidation reaction, harm one's eyes.Under the condition of aerobic, blue light stimulation based retinal starts photoxidation mechanism, accelerates oxidizing reaction, destroys the normal redox running balance of body, causes photosensory cell apoptosis, now thinks the effect of lipofuscin and blue light and causes macular degeneration.
The harm of blue light is ubiquitous in our life, is enjoying in happy that electronic product brings, and selecting the pre-anti-blue light injury of the function and protecting film having no side effect eyes is well selections.
For above problem, the present invention relates to a kind of anti-blue light protective membrane, it is mainly by the absorption of blue light and change into the visible ray of its all band, realizes and intercepts blue light, can greatly alleviate the stimulation of blue light to eyes, controls near-sighted intensification.
