Description
Technical field
The present invention relates to a kind of glasses and manufacture method thereof.More particularly, the present invention relates to a kind of anti-blue light injury glasses sheet and manufacture method thereof.
Background technology
For accurate description content of the present invention, at first following term is made explanations or define.
Ultraviolet light: be meant that wavelength is the light of 200～380nm.Divide extreme ultraviolet (200～315nm) and near ultraviolet (315～380nm) again.
Visible light, shortwave light and long wave visible light: the wavelength of visible light zone is 380～780nm.Wherein, the wavelength region may of purple light is 380～430nm, and the wavelength of blue light is 430～470nm, and the crest of ethereal blue light is at 470nm.The wavelength of purple light is shortwave in the visible region, its frequency is the highest, and blue light takes second place, so claim that wavelength is that the light in 380～470nm zone is shortwave light.So, the visible light at 470～780nm just claims the long wave visible light or claims effective visible light.
The blue light injury: result of study shows in recent years: shortwave light, particularly purple light have sizable injury effect to retina, thereby this injury effect is by retinal pigment epithelium being caused direct infringement cause and accelerate treating senile maculopathy etc.Although the energy of purple light is also more serious than blue light to the injury of eyes than blue light height, in western countries, people are commonly referred to as blue light injury (Blue light hazard) by purple light, blue light to amphiblestroid injury effect this.
Anti-blue light injury lens: be meant any to purple light and the selective filtration of blue streak and to the lens of other visible wavelength region light transmission capacity greater than shortwave light.In addition, this eyeglass elimination ultraviolet light fully usually.
Vapor-deposited film: be meant under the vacuum environment, make the coating materials evaporation be deposited on substrate surface, form firm thin layer with the form of molecule with the electronic beam current heating.In general, coatings is by forming for the Coating Materials low, high index of refraction with unit replaces repeatedly evaporation with nanometer.
As everyone knows, ultraviolet light has strong destructiveness to the eyes cell.Ultraviolet light to eye's cornea, natural crystal, and retina three structure direct detrimental effect is all arranged.Long term exposure causes the cataract or glaucoma of early turning white easily in the eyes of ultraviolet light, and retinal pigment epithelium is caused direct infringement and causes and accelerate treating senile maculopathy etc.Find by medical research and experiment in recent years, not only ultraviolet light has very major injury effect to eye, and the short wavelength light of the 380nm in visible light～450nm wavelength also has suitable injury effect to eye, its injury object mainly is a retina, as shown in Figure 1, along with reducing of wavelength of light, shortwave light increases sharply to the degree of retinal damage; Result of study in recent years also shows (Shabanand and Richter, " A2E and Blue Light in the Retina:The Paradigm of Age～RelatedMacular Degeneration " Biol.Chem.Vol.383 Pages 537～545,2002): blue light injury (particularly at the purplish blue light of wavelength about 435nm) equally also can cause and quicken the malignant development of old macula retinae sex change.And old macula retinae sex change accounts for about 20% of this crowd's total population in the crowd of over-65s.To so far, medical circle to old macula retinae sex change without any cure method.Therefore, concerning the old consumer of over-65s, be necessary to wear the health-care mirror of energy anti-blue light injury fully.
In addition, the blue light injury also has special damaging effect to the patient behind the cataract operation.This is because people's intraocular natural crystal all is water white in firm birth and youthful age, is (the seeing Fig. 2 curve of spectrum A) that sees through basically to all visible lights that comprise purple light and blue light.But after entering the youth, the nature crystal begins to become faint yellow while energy stop portions purple light and thereby blue light makes retina alleviate the blue light injury, along with the increase of year order, this function that stops and filter purple light and blue light also increases (seeing Fig. 2 curve of spectrum B) along with the intensification of natural crystal color.So the patient after cataract has been extractd, the natural crystal that can filter shortwave light originally no longer exists, used artificial lens does not filter the shortwave light function again.Concerning this types of populations, the blue light injury is to amphiblestroid destructive maximum.In addition, the general reflection of cataract operation patient is that behind the implantable artificial crystal, All Around The World has all become too bright so that be impatient at.Concerning the up to ten million patients that implanted the artificial lens that do not have to absorb the blue light function, wear and have the elimination purple light and the blue light functional eyeglasses is unique health-care method.
Medical research also shows, in the visible region, eye is to the purple light and the part blue streak of 380nm～450nm wavelength, to looking thing and distinguishing that look is insensitive, just eyes are limited to the chromatic resolving power of the purple light of this wave band and part blue streak, but the light quantum energy level of this wave band is bigger to the eye retina damage ratio than higher (because wavelength is short); For example people although be the cloudy day, because the reflection of the short-wave band light in ultraviolet light and the visible light is strong especially, have the strong sense that twinges so people can feel eyes in snowfield; This sensation is arranged under high light equally,, force to dwindle pupil, to reduce irritating of above-mentioned ultraviolet light and short wavelength light so people under this environment, have to narrow eyes; The disease of eye such as easy as rolling off a log initiation cataract, colour blindness and the change of senile macula lutea venereal disease if people work under this environment for a long time; In order to protect eyes, people are under the summer high light or work in the snowfield, often wear coloured sunglasses and hide irritating of above-mentioned light; But present this sunglasses do not have the selectivity shading, so when hiding ultraviolet light, covered the visible light of all wavelengths yet; So it is lower to wear this common sunglasses chromatic discrimination power.Under cloudy day or low light environment, look thing and distinguish that the look performance is just poorer especially.
