Magirazi anozivikanwa nevanhu vazhinji, uye anoita basa guru mukugadzirisa myopia mumagirazi. Magirazi ane machira akasiyana-siyana ekufukidza, akadai segirini, bhuruu, bhuruu-pepuru, uye kunyange goridhe repamusoro. Kupera kwemavara ekufukidza ndicho chimwe chezvikonzero zvikuru zvekutsiva magirazi emaziso, saka ngatidzidzei zvakawanda nezvemachira ekufukidza emagirazi.
Kugadzirwa kwekuputira lenzi
Magirazi egirazi asati agadzirwa, ainyanya kushandiswa. Zvakanakira magirazi egirazi i refractive index yakakwirira, transmittance yakawanda yechiedza, uye kuomarara kwakanyanya, asi anewo matambudziko akadai sekuti anogona kutyoka, anorema, uye haana kuchengetedzeka.
Kuti vagadzirise matambudziko emagirazi, mafekitori akagadzira zvinhu zvakasiyana-siyana zvekutsiva magirazi, asi hapana chakakodzera. Chinhu chimwe nechimwe chine zvakanakira nezvachinokanganisa, uye zvakaoma kuwana chiyero. Izvi zvinoshandawo kumagirazi eresin aripo iye zvino (resin materials).
Kune marenzi eresin aripo iye zvino, kufukidza chinhu chinodiwa. Zvinhu zveresin zvinewo marudzi akasiyana-siyana, akadai seMR-7, MR-8, CR-39, PC, NK-55-C, nezvimwe zvinhu zvakawanda zveresin, chimwe nechimwe chine hunhu hwakasiyana. Pasinei nekuti igirazi here kana kuti resin, chiedza chinopfuura nepamusoro pelenzi chichasangana nezviitiko zvakasiyana-siyana zvemaziso: kuratidzwa, kudzorwa, kunyudzwa, kupararira, uye kutumirwa.
Kuputira lenzi nefirimu rinodzivirira kupenya
Chiedza chisati chasvika pamusoro pe lenzi, chinenge chave simba rechiedza 100%, asi kana chabuda mu lenzi chopinda muziso, hachisisiri simba rechiedza 100%. Kana chikamu chesimba rechiedza chakakwira, kutumirwa kwechiedza kuri nani, uye kunaka kwemifananidzo uye kugona kwayo kunowedzera.
Kune rimwe lenzi, kuderedza kurasikirwa nekupenya inzira yakajairika yekuwedzera kupenya kwechiedza. Kana chiedza chikapenya zvakanyanya, kupenya kwelenzi kunoderedza, zvichikonzera kunaka kwemifananidzo. Saka, kuderedza kupenya kwave dambudziko rinofanira kugadziriswa nema lenzi e resin, uye firimu rinodzivirira kupenya (AR film) rakaiswa kune lenzi (pakutanga, machira anodzivirira kupenya aishandiswa pane mamwe ma lenzi e optical).
Firimu rinodzivirira kupenya rinoshandisa musimboti wekupindirana kuti riwane hukama huripo pakati pekupenya kwechiedza kwelenzi yakaputirwa nelenzi inorwisa kupenya uye kureba kwechiedza chinobuda, ukobvu hwelenzi yefirimu, refractive index yelenzi yefirimu, uye refractive index yelenzi, zvichibvumira chiedza chinopfuura nepalenzi yefirimu kuti chidzikise kupenya, zvichideredza kurasikirwa nesimba rechiedza pamusoro pelenzi uye zvichivandudza kunaka kwemifananidzo uye kugadziriswa kwayo.
Machira ekudzivirira kupenya anowanzo shandisa ma oxide esimbi akachena zvakanyanya akadai setitanium dioxide ne cobalt oxide, ayo anoiswa pamusoro pe lens kuburikidza ne evaporation process (vacuum deposition) kuti awane mhedzisiro yakanaka yekudzivirira kupenya. Machira ekudzivirira kupenya anowanzo siya masara, uye akawanda ma layers efirimu anonyanya kuve mumhando yegirini.
Ruvara rwefirimu rinodzivirira kupenya runogona kudzorwa, semuenzaniso, kugadzira firimu rebhuruu, firimu rebhuruu-violet, firimu reruvara rwepepuru, firimu regrey, nezvimwewo. Mafirimu ane mavara akasiyana ane musiyano mukugadzirwa. Semuenzaniso, firimu rebhuruu rinoreva kuti kupenya kwakaderera kunofanirwa kudzorwa, uye kuoma kwekuputira kwakakura kupfuura kwefirimu regirini. Zvisinei, musiyano wekufambiswa kwechiedza pakati pemafirimu ebhuruu negirini unogona kunge uri pasi pe1%.
Muzvigadzirwa zvemalenzi, mafirimu ebhuruu anowanzoonekwa mumalenzi epakati kusvika epamusoro. Panyaya iyi, kufambiswa kwechiedza kwemafirimu ebhuruu kwakakwira kupfuura kwemafirimu egirini (cherechedza kuti izvi ndizvo zvazviri) nekuti chiedza musanganiswa wemarefu akasiyana ehurefu, uye marefu akasiyana ane nzvimbo dzakasiyana dzemifananidzo pa retina. Mumamiriro ezvinhu akajairwa, chiedza cheyero-girini chinoratidzwa chaizvo pa retina, uye ruzivo rwekuona rwunobva kuchiedza chegirini rwakakwira, saka ziso remunhu rinonzwa chiedza chegirini.
Kuputira lenzi nefirimu rakaoma
Pamusoro pekufambiswa kwechiedza, resin negirazi zvine dambudziko guru: magirazi haana kuoma zvakakwana.
Mhinduro ndeyekugadzirisa izvi nekuwedzera jira rakaoma repurasitiki.
Kuomarara kwepamusoro kwemagirazi egirazi kwakanyanya (kazhinji zvichisiya madonhwe mashoma kana akakwenywa nezvinhu zvakajairika), asi izvi hazvisizvo kune magirazi eresin. Magirazi eresin anokwenywa zviri nyore nezvinhu zvakaoma, zvichiratidza kuti haaparadzi kupfeka.
Kuti lenzi irambe ichidzivirira kupera kwebvudzi, zvakakosha kuwedzera jira rakaoma pamusoro pe lenzi. Majira akaoma anowanzo shandisa maatomu e silicon pakugadzirisa kuoma, achishandisa mhinduro yekuomesa ine matrix ye organic uye inorganic ultrafine particles kusanganisira silicon elements. Firimu rakaoma panguva imwe chete rine kusimba uye kuomarara (jira refirimu pamusoro pe lenzi rakaoma, uye substrate ye lenzi haina kuputsika zvakanyanya, kusiyana negirazi rinotyoka nyore nyore).
Tekinoroji huru yemazuva ano yekufukidza firimu rakaoma ndeyekunyudza. Kufukidza firimu rakaoma kwakakora zvishoma, kungangoita 3-5μm. Kune ma lenzi e resin ane firimu rakaoma, anogona kuzivikanwa neruzha rwekubata pa desktop uye kupenya kweruvara rwe lenzi. Ma lenzi anogadzira ruzha rwakajeka uye ane mipendero yakajeka akagadziriswa zvakanyanya.
Kuputira lenzi nefirimu rinodzivirira kusvibiswa.
Firimu rinodzivirira kupenya uye firimu rakaoma ndizvo zvinhu zviviri zvakakosha zvema lenzi e resin parizvino. Kazhinji, firimu rakaoma rinotanga ravharwa, rozoteverwa nefirimu rinodzivirira kupenya. Nekuda kwemiganhu iripo yezvinhu zvemafirimu zvinodzivirira kupenya, pane kusawirirana pakati pesimba rekudzivirira kupenya uye rekudzivirira kusvibiswa. Nekuti firimu rinodzivirira kupenya riri mumamiriro ekupinza, rinonyanya kukonzera mavara pamusoro pe lenzi.
Mhinduro ndeyekuwedzera firimu rekudzivirira kusvibiswa pamusoro pefirimu rekudzivirira kusvibiswa. Firimu rekudzivirira kusvibiswa rinonyanya kuumbwa nefluoride, iyo inogona kufukidza firimu rekudzivirira kusvibiswa, kuderedza nzvimbo yekubatana pakati pemvura, mafuta, nelenzi, ukuwo isingachinji mashandiro ekuona efirimu rekudzivirira kusvibiswa.
Nekuwedzera kwekusiyana kwezvinodiwa, ma layer efirimu anoshanda zvakanyanya akagadzirwa, akadai se polarizing film, anti-static film, blue light protection film, anti-fog film, nedzimwe functional film layer. Lenzi imwechete, lenzi imwe chete refractive index, ma brand akasiyana, uye kunyangwe mukati me brand imwe chete, nechinhu chimwe chete, ma lenzi akasiyana ane mutsauko wemitengo, uye ma lenzi e coatings ndeimwe yezvikonzero. Kune mutsauko mu tekinoroji uye mhando yema coatings.
Kune mhando zhinji dzemafirimu, zvinonetsa kuti munhuwo zvake aone mutsauko. Zvisinei, kune rumwe rudzi rwemafirimu apo mhedzisiro yacho inogona kuonekwa zviri nyore: magirazi ebhuruu anovhara chiedza (tekinoroji inowanzoshandiswa mumagirazi ebhuruu anovhara chiedza).
Lenzi yebhuruu inovhara chiedza yakanaka inobvisa chiedza chebhuruu chine njodzi muhukuru hwe380-460nm kuburikidza nefirimu rebhuruu rinovhara chiedza. Zvisinei, pane musiyano mukushanda chaiko pakati pezvigadzirwa zvinobva kuvagadziri vakasiyana. Zvigadzirwa zvakasiyana zvinoratidza musiyano mukushanda kwechiedza chebhuruu, ruvara rwekutanga, uye kutumirwa kwechiedza, izvo zvinotungamira kumitengo yakasiyana.
Dziviriro yekuvhara magirazi
Magirazi egirazi anonzwa tembiricha yepamusoro. Magirazi ari pamagirazi eresin anozoiswa gare gare uye ese ane utera hwakafanana: anonzwa tembiricha yepamusoro. Kudzivirira magirazi egirazi kuti asaputika kunogona kuwedzera hupenyu hwemagirazi. Nzvimbo dzinotevera dzinogona kukonzera kukuvara kwemagirazi:
1. Kuisa magirazi padashboard yemotokari masikati muzhizha.
2. Kupfeka magirazi kana kuaisa pedyo paunenge uchishandisa sauna, uchigeza, kana kunyikwa muchitubu chinopisa.
3. Kubikira mukicheni pakupisa kwakanyanya kwemafuta; kana mafuta anopisa akapararira pamalenzi, anogona kuputika ipapo ipapo.
4. Pakudya hot pot, kana soup inopisa ikapfachukira pamalenzi, inogona kuputika.
5. Kusiya magirazi pedyo nemidziyo yemumba inokonzera kupisa kwenguva yakareba, zvakaita semarambi epadhesiki, materevhizheni, nezvimwewo.
Kuwedzera pane zvataurwa pamusoro apa, zvakakoshawo kuti usashandise mvura ine acid kana alkaline kuti mafuremu kana malenzi asasvibe.
Kuputika kwemachira egirazi nekukwenya kwakasiyana zvachose. Kuputika kunokonzerwa nekusangana nekupisa kwakanyanya kana makemikari emvura, nepo kukwenya kunokonzerwa nekucheneswa kusina kunaka kana kukanganiswa nekunze.
Muchokwadi, magirazi chinhu chinonaka. Anonzwa kumanikidzwa, kudonha, kukotama, kupisa kwakanyanya, uye mvura inoparadza.
Kuti uchengetedze mashandiro ekuona kwechikamu chefirimu, zvakakosha kuti:
1.Paunobvisa magirazi ako, aise mubhokisi rekudzivirira woachengeta panzvimbo isingasvikwe nevana.
2. Geza magirazi nesipo isina kunyoroveswa uchishandisa mvura inotonhorera. Hazvikurudzirwi kushandisa chero imwe mvura kuchenesa magirazi.
3. Munzvimbo dzine tembiricha yepamusoro (kunyanya panguva yekugeza kana kubika), zvinokurudzirwa kupfeka magirazi ekare kudzivirira kukuvara kwemagirazi matsva.
Vamwe vanhu vanogona kusuka magirazi avo nemvura inodziya pavanenge vachigeza bvudzi ravo, kumeso, kana kushawa kuitira kuti magirazi acheneswe. Zvisinei, izvi zvinogona kukonzera kukuvara kukuru kwejira remagirazi uye zvinogona kuita kuti magirazi asashande. Zvakakosha kusimbisa kuti magirazi anofanira kucheneswa chete nesipo isina kunyoroveswa uchishandisa mvura inotonhorera!
Mukupedzisa
Nekufambira mberi kuri kuita tekinoroji yekuputira, zvigadzirwa zvemazuva ano zvemaziso zvakafambira mberi zvakanyanya mukufambisa chiedza, kudzivirira kukwenya, uye kudzivirira kusvibiswa. Ruzhinji rwema lenzi e resin, ma lenzi ePC, uye ma lenzi e acrylic zvinogona kusangana nezvinodiwa nevanhu zvezuva nezuva maererano nekugadzirwa kwekuputira.
Sezvambotaurwa pamusoro apa, magirazi emaziso zvinhu zvine hunyoro, zvine chekuita netekinoroji yekufukidza yefirimu, kunyanya zvinodiwa zvakanyanya pakushandiswa kwekupisa. Chekupedzisira, ndinoda kukuyeuchidzai: kana mawana kukuvara kwefirimu yegirazi rako, ritsive nekukurumidza. Usambofa wakaramba uchirishandisa zvisina hanya. Kukuvadzwa kwefirimu kunogona kuchinja mashandiro ekuona kwemalenzi. Kunyange zvazvo malenzi maviri ari nyaya diki, hutano hwemaziso hunokosha zvikuru.
