Nyaya dzinoda kutarisirwa
① Kana uchifananidza magirazi, saizi yefuremu inodiwa zvakanyanya pakusarudza furemu.Kureba uye kureba kwefuremu kunofanirwa kusarudzwa zvichienderana nenhambwe yevadzidzi.
②Mushure mekupfeka magirazi, kana uchitarisa zvinhu pamativi ese, unogona kuona kuti tsananguro yakaderedzwa uye chinhu chinoonekwa chakaremara, izvo zvakajairika.Panguva ino, iwe unofanirwa kushandura musoro wako zvishoma uye edza kuona kubva pakati pe lens, uye kusagadzikana kuchapera.
③Kana uchidzika pasi, magirazi anofanirwa kudzikiswa kusvika kure sezvinobvira kubva kumusoro kuti uone kunze.
④Glaucoma, kukuvara kwemaziso, chirwere cheziso chakakomba, hypertension, cervical spondylosis nevamwe vanhu havakurudzirwe kushandisa.
Wakambonzwa nezvemagirazi ekusimudza?Kubva kune imwe-yakatarisana lenzi, bifocal lenzi uye ikozvino inofambira mberi multifocus lenzi,
Progressive multifocus lenses yakashandiswa zvakanyanya mu myopia control lens yevechiri kuyaruka, anti-kuneta lenses kune vakuru uye inofambira mberi lenzi yepakati-kati uye vanhu vakura.Iwe unonyatsoziva kufambira mberi multifocus lenses?
01Nzvimbo nhatu dzinoshanda dzekufambira mberi multifocus lenses
Nzvimbo yekutanga inoshanda iri panzvimbo yepamusoro yenzvimbo iri kure ye lens.Nzvimbo iri kure idhigirii rinodiwa kuona kure, rinoshandiswa kuona zvinhu zviri kure.
Yechipiri inoshanda nzvimbo iri pedyo nechezasi kumucheto kwe lens.Iyo yepedyo zone idhigirii rinodiwa kuti uone pedyo, rinoshandiswa kuona zvinhu zviri pedyo.
Nzvimbo yechitatu inoshanda chikamu chepakati chinobatanidza zviviri, zvinonzi nzvimbo yegradient, iyo zvishoma nezvishoma uye inoramba ichichinja kubva kure kuenda kune pedyo, kuitira kuti iwe ugone kuishandisa kuona zvinhu zviri pakati-kure.
Kubva kunze, kufambira mberi kwema-multifocus lenses hakuna kusiyana kubva kune akajairwa lenzi.
02Mhedzisiro yekufambira mberi multifocus lenses
① Progressive multifocus lenses akagadzirirwa kupa varwere presbyopia nenzira yechisikigo, iri nyore uye yakagadzikana yekururamisa.Kupfeka lens inofambira mberi kwakafanana nekushandisa vhidhiyo kamera.Magirazi maviri anogona kuona zvose zviri kure uye pedyo, pamwe chete nezvinhu zviri pakati-kure.Saka tinotsanangura malenzi anofambira mberi se "zoom lenzi", peya imwe yemagirazi yakaenzana nemagirazi akawanda.
② Kudzikisira kuneta kwekuona uye kudzora kukura kwe myopia, asi havasi vese vechidiki vanokodzera kupfeka anofambira mberi akawanda-anotarisisa magirazi, mhomho yakawandisa, iyo lens inongove neimwe mhedzisiro pakugadzirisa lag neine oblique myopia vana. .
Cherechedza: Sezvo varwere vazhinji vane myopia vane kunze kwekunze kwete mukati, nhamba yevanhu vakakodzera kupfeka magirazi anofambira mberi akawanda-yakatarisa kudzora myopia ishoma, inotora 10% chete yevana nevechiri kuyaruka myopia.
③ Malenzi anofambira mberi anogona zvakare kushandiswa kudzoreredza kuneta kwekuona kune vechidiki nevepakati-kati.Semusana wevanhu, kuneta kwemaziso kwevaduku nevepakati-kati kunowedzera kufanirwa kutarisirwa.Malenzi anofambira mberi anogona kunge akafanana neanopesana nekuneta lenses kuti abvise kuneta kwekuona muvashandisi vekombuta, uye anogona zvakare kushandiswa sekuchinja lenzi kuve nechokwadi chenguva refu, yepakati uye pedyo-yakatarisana yakawanda-yakatarisana muono mune ramangwana.
03Sarudzo yekufambira mberi multifocal magirazi
Shape zvinodiwa
Rega kusarudza mafuremu ane hombe nasal bevel nekuti nzvimbo yepedyo yemafuremu akadaro idiki.
Zvinhu zvinodiwa
Zvakanakisa kusasarudza mahwendefa uye TR mafuremu pasina mhino pads.Izvi zvinodaro nekuti chinhambwe cheziso chemafuremu akadaro chinowanzo diki (chinofanirwa kuchengetedzwa chinosvika 12mm kazhinji), ziso riri pedyo harigone kusvika panzvimbo yenzvimbo iri pedyo-kushandiswa kazhinji, uye zvakaoma kugadzirisa kurerekera. Angle yemagirazi.
Saizi yechikumbiro
Kureba kwakatwasuka kunoenderana nenzvimbo yemudzidzi wefuremu kunofanirwa kuzadzisa zvinodiwa zvinotsanangurwa nechigadzirwa, icho chinowanzo hukuru kupfuura kana kuenzana nezvinodiwa zve16MM+ chiteshi kureba.Kana pane zvakakosha zvinodiwa, unofanirwa kutarisa kune izvo zvinodikanwa zve lens kuti usarudze saizi yakakodzera yefuremu.
Izvo zvinodiwa zvekuita
Mafuremu ane kugadzikana kwakanaka anofanirwa kusarudzwa kuti adzivise deformation yenguva dzose yemagirazi inokanganisa zvinodiwa zvekushandisa.Magirazi anogona kuchengetwa paAngle ye10 kusvika ku15 madhigirii.Chiso chakakombama chefuremu chinofanirwa kuenderana nemakona echiso chemupfeki.Kureba, kupenya uye kusimba kwegirazi kwakakodzera kupfeka kwakajairika.
