Description
Technical field
The present invention relates to a kind of manufacture method of eyeglass, relate in particular to that a kind of to make a kind of filter effect good so that enter the safer eyeglass of the light of eyes.
Background technology
The eyes existence is not suitable with in many luminous environments, even relevant disease of eye occurs, such as snow blindness, photic cataract, photic PVR, video display terminal syndrome etc.And the impression that eyes can produce euphorosia in some luminous environments, as be in the grassland and particularly produce eye-candy and moist impression in the forest.Above-mentioned objective phenomenon shows that luminous environment has directly related property to visual effect and eye health.In order to prevent bad luminous environment to the harm of eye health, improve visual adaptability and validity, lens need to have good optical filtering performance.All be the lens with optical filtering performance such as sunglasses eyeglass, color-changing lens, welding optical filter, lasing safety eyeglass etc.
The optical filtering performance of lens used in everyday normally adopts to mix with exhaust process and realizes.Mixing is blending technology, eyeglass optical filtering degree and thickness correlativity in direct ratio, thereby be applicable to plano lens, inapplicable ametropia lens, reason is that ametropia lens is non-equal thickness, certainly leads to " opal " such as myopia (negative dioptric) eyeglass, i.e. the light edge of the Neutral colour of eyeglass color depth phenomenon; Dip-dye is surperficial osmosis process, the inversely proportional correlativity of skin hardness of the optical filtering performance of eyeglass and eyeglass, because lens surface hardness can not be consistent, eyeglass certainly leads to aberration between sheet.Its optical filtering consistency of performance of filter glass that is exhaust process is poor.
Patent document in existing disclosed manufacture method relevant for eyeglass, such as Chinese patent: the lip-deep hard conating that " optical filter and manufacture method thereof (CN101750661A) " this optical filter comprises basement membrane and is formed on basement membrane, hard conating has the conductive materials in the zone that is arranged at contiguous basement membrane.The method comprises: the basement membrane of preparation printing opacity; Applying liquid is coated with raw material firmly on a surface of basement membrane, firmly is coated with raw material and has the conductive materials that mixes with it; And be gathered at conductive materials to solidify under the state in zone of contiguous basement membrane and firmly be coated with raw material, be coated with firmly that raw material is formed between the conductive materials and on.The optical filtering performance of this optical filter is determined jointly that by liquid crystal layer, conductive layer institute making alive, three-primary colours pixel three factors the coating Main Function of addressing is the protection conductive layer, does not play filter action.
Summary of the invention
It is good to the invention provides a kind of filter effect, is applicable to ametropia lens, and technological process is relatively simple, and filter coating firmly invests the manufacture method of a kind of filter goggle sheet of lens surface; Solved the insufficient and inconsistent defective of optical filtering performance of optical filtering performance of the ametropia lens that exists in the prior art.
Above-mentioned technical matters of the present invention solves by following technical proposals: a kind of manufacture method of filter goggle sheet is characterized in that:
The first step is selected substrate, and substrate is cleaned and dries;
Second step, configuration filter liquor: with the abundant dissolved dilution of light absorber, the light absorber solution behind the dissolved dilution is added in the organic siliconresin, fully stir and filtration becomes filter liquor;
The 3rd step, apply filter coating: the substrate after will cleaning and dry immerses in the filter liquor, then the extraction eyeglass of uniform speed slow, the one side of the substrate after maybe will cleaning and dry is sprayed filter liquor, then rotates eyeglass and forms uniform filter membranous layer by filter liquor at lens surface;
In the 4th step, filter coating solidifies: with eyeglass precuring 5 ~ 25 minutes under 50 ℃ ~ 90 ℃ temperature, then be no less than 2 hours 110 ℃ ~ 140 ℃ lower curing;
In the 5th step, vacuum coating: after filter coating solidified, eyeglass cleaned and dries, and carries out vacuum coating, eliminated the lens surface reflection and improved the lens surface anti-wear performance.
Eyeglass manufacturing process of the present invention is applicable to plano lens and ametropia lens, in the process of making, replaces original step that adds hard formation, utilizes the surface to apply filter coating as adding hard formation and filter layer.Rete optical filtering technique is to adopt take organic siliconresin as carrier, and the light absorber solution that adds the dilution hand becomes filter coating liquid, and filter liquor is coated on lens surface through solidifying to form skin hardness height, strong adhesion, filter membranous layer that optical property is stable.Configuration by filter liquor guarantees that the optical filtering performance of eyeglass is definite value, and stable homogeneous.Applying filter coating adopts dipping to adhere to or spin coating method.The dipping adherence method is that eyeglass is immersed in the filter liquor, speed with 0.2 ~ 2.0 mm/second promotes eyeglass, spin coating method is to spray a certain amount of filter liquor at lens surface, speed rotation eyeglass with 5 ~ 50 revolutions per seconds, so that filter liquor can be distributed on the eyeglass, simultaneously firmly and uniformly be attached to lens surface, form uniform filter coating.Filter effect is good, and optical property is stable, the eyeglass of applicable various different dioptric forms.
The optical filtering performance of eyeglass is determined that by filter layer the optical filtering performance of filter layer is determined that by the compatibility of filter liquor namely kind and the quantity by the light absorber that adds determines in a certain amount of organic siliconresin.Can obtain required optical protection performance by the compatibility that changes filter liquor according to different requirement of shelter.As: the optical filtering performance of Sunglasses lenses sun clips is to reduce luminous flux as major requirement; Photic eye illness (photic cataract, photic PVR, photic keratitis) protection glass is take control and filtering biological radiation injury (ultraviolet damage, blue light damage) as major requirement; Fatigability eye illness (visual fatigue, the day after tomorrow axial myopia, video display terminal syndrome) protection glass is to improve visual efficiency as major requirement.The driving mirror eyeglass is with raising dark adatpation ability and the light degree of depth, and the elimination dazzle is major requirement.
