Zhizha riri kupisa kupisa, rinogadzirira zororo diki refu kuenda kunze kweshamwari kuti zvigoneke zvakanaka kuenda kunze kunonakidzwa nechiedza chezuva.Asi kune shamwari dzinopfeka magirazi, asi maziso photophobia, haigoni kutevera mwoyo kupfeka magirazi ezuva kana kuti inoda kupfeka magirazi maviri ekutambudzika.
Zvizhinji zvekupfeka magirazi emyopic emudiwa mudiki, mwaka wechirimo wechirimo une musoro usingaregi: zvakare myopic sei kupfeka sunglass zvakare inoda kudzivirira kubva kuzuva?Daily Commute sunscreen ganda haigone kudzivirira ziso kuita sei?Myopic drive inofanira kuita sei zvakare?
Tarisa pamufananidzo uri pamusoro.Ungada here kupfeka magirazi ane tinted ane nhamba ye dioptre, kana magirazi ane magirazi ezuva mukati?
Muzuva rinopisa kana chiedza chinoratidza chando chakakomba, mvura, chiedza chinobudisa kukurudzira kukuru kumaziso.Panguva ino, vanhu vanowanzosarudza magirazi ekuderedza chiedza kumaziso ekukurudzira.
Asi kana vanhu vakapfeka magirazi ezuva, muimba yerima havazokwanisi kuona zvinhu uye zvakatipoteredza, kunyanya kune shamwari dzinoona pfupi, zvinongova "maziso maviri madema" , magirazi ezuva haana kunaka.Naizvozvo, nzira yakanakisa yekudzivirira maziso ako kubva mukukuvadzwa kweUV uku uchitarisirawo matambudziko ekubvisa ndeyekupfeka magirazi anodzivirira uv.Magirazi anochinja-ruvara zvirokwazvo magirazi ari nyore uye anoshanda, asi iwe unoziva nei iyo Lens ichachinja ruvara?Ndezvipi zvakanakira magirazi ekuchinja-mavara?
1, Sei chromotropic Lens inogona Kuchinja Ruvara?
Mavara Anochinja Malenzi, anotonzi Photochromic Lens, malenzi anochinja ruvara zvichienderana nekusimba kwechiedza cheultraviolet uye tembiricha.Iyo iri mune yakajairwa resin lens yekuwedzera akasiyana photosensitizers, senge sirivheri Halide, sirivheri barium acid, mhangura halide uye chromium halide.Mushure mekuchinja kwemavara kunogona kuva nemuvara wakasiyana, senge tawny, Tawny Grey, grey uye zvichingodaro.
Nheyo yekubvisa ruvara:
Kana iyo discoloration Lens inogadzirwa, iyo yakakodzera huwandu hwesirivheri halide inowedzerwa se photosensitizer.Silver Halide ndiyo IONIC musanganiswa weHalogen uye sirivheri.Sirivha halide iripo mugirazi-inoshandura ruvara ikristaro diki ine twudiki diki uye yakaparadzirwa zvakafanana muLens.Nekuti yunifomu uye diki, saka kana chiedza irradiation, kazhinji havaratidzi kuparadzira chiitiko.Izvi zvinoitawo kuti magirazi ane tinted ataridzike akajeka uye akajeka semagirazi enguva dzose.Kana yakavhenekerwa nechiedza (kunyanya short-wave light), mamorekuru esirivheri halide ari muLens anoputsika kuita maatomu esirivha nehalogen, anotaridza kana kuparadzira mwenje, kuunganidzwa kwemaatomu mazhinji esirivheri kunoita kuti malenzi aratidzike matema, kana grey. .
Iyo Lens inochinja-ruvara yakasimba.Kunyangwe iyo silver halide crystal ichaora pasi pechiedza chakasimba, sirivheri nehalogen maatomu anogadzirwa nemakemikari anoita ari padhuze padhuze uye haazopukunyuki, kana mwenje wamira, inodzokera kune iyo silver halide state nekukurumidza, zvichiita kuti lens ioneke. zvakare.Mukuwedzera, shoma shoma yemhangura oxide yakawedzerwa kune maLenses anoshandura mavara, ayo akashanda sechinhu chinokonzera uye akakurumidza kuora kwesirivha halide pasi pekuvhenekera kwakasimba.
2, Discoloration Tekinoroji yeDiscoloration Lens
Parizvino, pane anonyanya marudzi maviri ehunyanzvi hwekuchinja-ruvara pamusika: Firimu-inoshandura ruvara uye substrate-inochinja-chinja ruvara.
Kuchinja kwefirimu ":inoreva pamusoro peiyo lens coating discoloration agent, inoratidzwa neyakajeka kumashure kweruvara padhuze nekusina ruvara, inozivikanwawo se spin-yakavharwa firimu shanduko.
Zvakanakira: kukurumidza kushanduka kwemavara, kuchinja kwemavara mamwe mayunifomu.
Zvakaipa: kusangana neyakakura tembiricha ruvara mhedzisiro inogona kukanganiswa kune imwe nhanho.Nemhaka yokuti chidimbu chekuwedzera chefirimu chinoshandura ruvara hachina kufanana neyefirimu inoshanda pamusoro peLens, firimu May Crack pasi pekuchinja kwekushisa kwenguva refu (mukati nekunze switching) .
Substrate discoloration ": iri mulens material monomer raw material processing link yakatosanganiswa mberi kwenguva mune discoloration agent.
Zvakanakira: kukurumidza kugadzira kukurumidza, yakakwira-inoshanda zvigadzirwa.
Zvakaipa:Kureba kweLens uye chikamu chepakati chemupendero wemuvara chichave chakasiyana, iyo aesthetic degree haina kunaka semufirimu chromotropic Lens.
3, Shanduko yeruvara rwe discoloration Lens
Kusviba uye kupenya kwemavara ekuchinja lenzi kunonyanya kuenderana nekusimba kwemwaranzi yeultraviolet, uye kusimba kwemwaranzi yeultraviolet inoenderana nenharaunda uye mwaka.
Mazuva eZuva: Makore emhepo yemangwanani akatetepa, mashoma ekuvharira UV, saka, mangwanani eLens inoshandura ruvara ichave yakasviba.Manheru, mwenje weUV hauna kusimba uye lenzi dzinoreruka.
Kufukidzira: Chiedza cheUV hachina kusimba pamazuva ekufukidzira, asi chichiri kukwanisa kusvika pasi, saka lenzi dzakatsvuka dzinogona kuramba dzichichinja ruvara kuti dzidzivirire, dzichiita kuti dzireruke kupfuura mazuva ezuva.
Tembiricha: pasi peyakajairika tembiricha mamiriro, sezvo tembiricha inowedzera, ruvara rwemavara-anochinja lenzi anozove akareruka zvishoma nezvishoma sezvo tembiricha inowedzera;ukuwo, kana tembiricha inodzikira, iwo mavara-anochinja lenzi achaita zvishoma nezvishoma kusviba.Nomutoo wakapfava, ikoku imhaka yokuti kana tembiricha yakakwira, maatomu esirivha nehalogen ayo akatoora achaderedzwa kuva halide yesirivha zvakare pasi pechiito chesimba guru, naizvozvo ruvara rwelens runova rwakareruka.———— ————Ichi ndicho chikonzero, muzhizha, kunyangwe mwaranzi yeUV yakanyanya, tembiricha yakakwira uye kupisa kwakanyanya pamusoro pemalenzi hakugone kuita kuti malenzi ave akasviba zvakanyanya, simba rayo reUV rinenge rakaenzana nezhizha UV kuratidzwa. , asi tembiricha yepamusoro ye lens yakaderera, ruvara ruchave rwakadzika.
Mukati meimba: Malenzi akatsvuka haawanzo chinja ruvara uye anoramba akajeka uye asina ruvara mukati, asi anogona kuramba achichinja ruvara kana akaiswa kune ambient UV mwenje, achipa ipapo kudzivirirwa kweUV.
4, Sei tichisarudza lenzi dzakatsvuka?
Nekuwedzera kweMyopia, vanhu vanoda kuwedzera uye kuwedzera-kuchinja-mavara lenses, kunyanya muchirimo nezhizha, zuva rinopisa, simba re ultraviolet rays, zvinogona kukonzera kukanganisa kwemaziso.
Ultraviolet mwaranzi kubva kuzuva yakakamurwa kuita mabhendi mana zvichienderana newavelength: UVA, UVB, UVC, UVD.UVA neUVB ndizvo zvikuru zvinopinda mumhepo zvichisvika pamusoro.
UVA, kureva, UVA, UVA, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB , UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, kunyanya muzhizha nemasikati.
Meso edu anogona kutora huwandu hwakasiyana hwewavelengths eUV, kunyura kwenguva refu kweUV kunogona kukonzera kukuvara kweziso:
macular degeneration: nekufamba kwenguva, retinal kukuvadzwa kunokonzerwa nemacular degeneration (AMD) , uye ndicho chikonzero chikuru chekupofumadza kwezera.KURATIRWA KWENGUVA KUDZORERA kuUV mwenje kunowedzera njodzi yekuderera kwe macular.
CATARACT: Cataract kuvharika kwelenzi yeziso, chikamu cheziso chinotariswa nechiedza.Kuratidzwa kune ultraviolet mwenje, kunyanya UVB, inowedzera njodzi yemamwe marudzi ecataract.Zvinofungidzirwa kuti 10 muzana yezvese cataract kesi zvinokonzereswa zvakanangana nekuratidzwa kweUV.
PTERYGIUM (N) : Inowanzonzi "ziso resurfer," PTERYGIUM rudzi rwepingi, rusina kenza rwunoita pachikamu che conjunctival pamusoro peziso.Uye chiedza che ultraviolet chinofungidzirwa kuti ndicho chinokonzera.
Heliokeratitis: inozivikanwawo sekorneal Kupisa kwezuva kana "kupofoma kwechando," Keratitis mhedzisiro yenguva pfupi yekuratidzwa kwemwaranzi yeUVB.Kufamba kwenguva refu pamhenderekedzo yegungwa kana pasina magirazi akakodzera kunogona kukonzera dambudziko, izvo zvinogona kutungamirira pakurasikirwa kwekuona kwechinguva.
Nokudaro, nokuda kwekudiwa kweSunscreen uye myopic vanhu vanoshandura dambudziko kune maziso ezuva ndiro sarudzo yekutanga yekuchinja-mavara lenses.
