Description
Technical field
The present invention relates to a kind of eyeglass and preparation method thereof, more particularly, relate to a kind of medical multifunctional safety goggles eyeglass and preparation method thereof.
Background technology
As everyone knows, ultraviolet ray has strong destructiveness to people's eyes cell.Cornea, natural crystal and the retina three of ultraviolet ray to eyes structure all has direct detrimental effect.The eyes of long term exposure under ultraviolet ray easily cause cataract, and retinal pigment epithelium is caused direct infringement and causes and accelerate senile maculopathy etc.
In recent years, find by medical research and experiment, not only ultraviolet ray has very large injury effect to eye, and in the short wavelength light of the 380nm～500nm of visible ray wavelength, eye is also had to sizable injury effect, the chromatic resolving power of the purple light of eye to 380nm～500nm wavelength and blue light is limited, depending on thing and distinguish that look insensitive, but the wavelength of this wave band is short, energy is high, thereby by cause direct infringement to cause and accelerate treating senile maculopathy etc. to retinal pigment epithelium.Although the energy Ratios blue light of purple light is high, also serious than blue light to the injury of eyes, in western countries, people are commonly referred to as blue light injury by purple light, blue light to amphiblestroid injury effect this.Medical research also shows, blue light injury also has special damaging effect to the patient after cataract operation, this is because of for people's intraocular natural crystal is just birth and youthful age are all water white, all visible rays including purple light and blue light are seen through substantially, but enter after youth, nature crystal starts to become faint yellow, energy stop portions purple light and blue light simultaneously, thereby alleviate amphiblestroid blue light injury, along with the increase at age, this function stopping and filter purple light and blue light also increases along with the intensification of natural crystal color.Concerning cataract has been extractd the patient of nature crystal, the natural crystal that can filter shortwave light originally no longer exists, and artificial lens used does not filter again shortwave light function.Concerning this class patient, blue light injury is very large to amphiblestroid destructiveness.In addition, for a long time there is the disease of eye such as the as easy as rolling off a log initiation cataract of crowd (as the medical worker of hospital), colour blindness and the treating senile maculopathy of working under the environment of blue light injury.
Also have, along with scientific and technological progress, blue light injury has been penetrated in people's life, such as LED lamp conventional in daily life, computer, mobile phone etc., the blue light strength that these equipment send has approached the blue light strength in sunlight at noon, and light emitting source from the distance of eyes very close to.At present, injure for blue light, can only start with from prevention, do not allow blue light injure eye eyesight, normally wear the glasses that a pair has anti-blue light eyeglass, most of Sunglasses lenses sun clips generally can only be kept out ultraviolet ray or the infrared ray in sunlight on the market, is difficult to keep out for the stronger blue light of penetrating power and purple light.Also have on the market some anti-blue light glasses, but mostly the eyeglass of these glasses is to realize by some retes the effect of anti-blue light, in glasses use and cleaning process, can injures these anti-blue light retes, will reduce in the course of time the effect of anti-blue light.
Chinese Patent Application No. 201210161746.1, Shen Qing Publication day is on September 19th, 2012, invention and created name is: anti-blue light amber protection glass, this application case relates to one and has amber anti-blue light protection safety glasses.This eyeglass is by 100,000 parts of polycarbonates, 3.75～4.13 parts of BK2 toners, and 8,150 61.51～67.65 parts of toners, 5.11～5.61 parts of red G toners are mixed with and form.The eyeglass of this application case is mainly that the blue light of blue visible light is reached to the function that filtration can intercept, avoid the injury of blue light to eyes, be beneficial to the eye illnesses such as prevention macula retinae district pathology, there is the work crowd under blue light environment applicable to commercial production protection or the nature high light of being everlasting etc., but BK2 toner, 8150 toners and red G toner in its component all need be obtained by Taiwan or Japanese import, cost is higher, select common material to be all difficult to produce a desired effect, therefore there is larger limitation, be not easy to promote the use of.
