Description
Technical field
The present invention relates to a kind of lens technology field, especially relate to that a kind of filter blue light radiation proof 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.
Current eyeglass of a great variety, as 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.
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, retinal pigment epithelium is very strong to the light absorption effect of blue region, absorbs blue ray radiation and can make retinal pigment epithelium atrophy, and 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.
In addition, along with computer, TV etc. are extensively universal, the quantity of myopia population is increased sharply, and the key factor wherein affecting eye eyesight is exactly radiation.Eyes are to one of highstrung organ of electromagnetic radiation in human body.Radiation can cause crystallins to solidify, muddy, form cataract, also can damage cornea, cause visual fatigue, visual impairment even loses.Therefore, the glasses of radiation proof eyeglass are adopted to protect eyes to be relatively simple and effective a kind of mode from radiation damage.
