Description
Technical field
The present invention relates to a kind of lens technology field, especially relate to that a kind of filter blue light anti glare anti static coatings is resistance to grind a lens and preparation method thereof.
Background technology
Along with people's culture, the improving constantly of living standard, carrying out of sight protection work, the simple optical device that glasses make as correcting defects of vision or protect eyes, has played important effect in people's sphere of life.Glasses are normally made up of eyeglass and mirror holder, and from eyeglass functionally, it has the light quantity that adjustment enters eyes, increase eyesight, effect such as protection eye-safe and clinical treatment illness in eye etc.
Such as, along with vehicle be on the increase and vehicle itself exist imperfection, traffic hazard also gets more and more, the particularly traffic hazard of driving at night generation, when the traffic hazard that vehicle running in the night occurs is often due to two car intersections, it is dazzling that the car light of both sides can make people produce, dizzy, the meeting blink of driver's instinct, even can lose blind a few second because of lamp from dazzling, so just easily cause traffic hazard, the sunglasses for the strong light offends our eyes market have been there are for this reason, half sunglasses, as sunglasses etc., but this kind of glasses are mostly the eyeglasses adopting polarized-light technique to make, the irradiation of diffuse light can only be reduced and really cannot reduce the intensity of incident ray, to people's Eye irritation, dazzling have certain anti-dazzle and the effect of being in the light are caused to sunburst on daytime, but in the night of dark, to reducing, the meet at night high light effect of stimulation that causes of driver is bad.
For another example, TAC polarized lenses common at present, it 100% obstruct can be harmful to light, therefore quite by the favor of consumer, be particularly suitable for outdoor exercises to use, but, in motion process, eyeglass is swiped unavoidably, therefore the rub proofness of eyeglass is also the Consideration that consumer chooses, TAC polarized lenses commercially available at present, the hardness on its surface can only reach H, its wearing quality is 1.5 grades, be easy to be scratched by hard object or break, affect the effect that user observes things, both made troubles to user, but also need often to change, increase use cost, have much room for improvement.
In addition, the high-energy visible ray of blue light to be wavelength be 400-500nm, blue light directly to penetrate cornea, eyes crystal, through retina, blue light can stimulate retina to produce a large amount of radical ion, make the atrophy of retinal pigment epithelium, and cause the death of photaesthesia cell, the light absorption effect of retinal pigment epithelium to blue region is very strong, absorb blue ray radiation and can make retinal pigment epithelium atrophy, this is also the one of the main reasons producing ARM; Blue ray radiation composition is higher larger to cellula visualis injury, and the atrophy of retinal pigment epithelium, can make amphiblestroid image thicken, and can do continuous adjustment, increase the weight of the working strength of ciliary muscle, cause visual fatigue fuzzy image ciliary muscle.Can cause the visual fatigue of people under the effect of ultraviolet and blue light, eyesight can decline gradually, easily causes dry and astringent, early onset cataract, the spontaneous macular diseases such as photophobia, fatigue on ocular vision.In order to avoid blue light injury, the optical mirror slip with partial filtration blue wave band is invented, and this optical mirror slip is also called anti-blue light eyeglass.Existing anti-blue light eyeglass is mostly utilize the anti-blue light eyeglass adding toner and make in lens materials, the patent No. disclosed in Chinese invention patent is the blue light resistant dark down sunglasses lenses of CN101813832A, utilize the anti-blue light eyeglass made at eyeglass top layer plated film in addition, as CN1564052 patent the blue-light injury proof health lens that discloses.
But the function of existing eyeglass is all more single, more and more can not meet the demand of people.
