Kubangane be-myopic, njalo lapho uya esitolo sezibuko ukukhetha ifreyimu yezibuko kuyinkinga yekhanda elibuhlungu kakhulu, kunzima ukukhetha izibuko ezifanele ezabo, ukuthi namuhla zikufundisa ukuthi ungakhetha kanjani izibuko ezifanele zabo. uzimele siqu.
Isinyathelo 1: Khetha usayizi wozimele
1, bheka izinga: i-myopia lens i-concave lens, eceleni kwe-concave lens ephakathi, i-degree ephakeme kakhulu, i-lens iyanda, ngakho-ke i-myopia degree iphakeme kakhulu abantu abancomi ukukhetha uhlaka olukhulu, hhayi oluhle. , kodwa futhi inzima kakhulu, kunconywa ukuba ukhethe ifreyimu encane.
2, bheka ubuso: ngokuvamile, abantu abanobuso obubanzi akufanele basebenzise amafreyimu amancane futhi amancane, ubuso obude obuncane akufanele busebenzise amafreyimu abanzi, uma ungubuso obuyindilinga obujwayelekile, ungakhetha noma yiziphi izibuko zohlobo lwefreyimu.
Isinyathelo sesi-2: Khetha umbala wohlaka
I-1, umbala wesikhumba omhlophe: khetha uhlaka lombala olukhanyayo, njenge-pink ethambile, igolide nesiliva;
2, Isikhumba esimnyama: Khetha amafreyimu amnyama, afana negobolondo elibomvu, elimnyama noma le-tortoiseshell.
I-3, Umbala wesikhumba ophuzi: gwema amafreyimu aphuzi futhi usebenzise imibala ekhanyayo efana nepinki, ikhofi ebomvu, isiliva nemhlophe;
4, umbala obomvu: gwema uhlaka olubomvu, ungakhetha okumpunga, okuluhlaza okotshani, uhlaka oluluhlaza okwesibhakabhaka, njll.
Isinyathelo sesi-3: Khetha uhlobo lohlaka
1, Uhlaka olugcwele uhlaka: kukhona indandatho yesibuko ephelele yokugoqa ilensi.Ifanele abasubathi nezingane ukugqoka.Ngenxa yokuthi indawo ezungezile yelensi ivikelwe ngokuphelele yindandatho yelensi, ifanele ilensi enamapharamitha ahlukahlukene e-refractive.
I-2, ifreyimu yohlaka oluyingxenye: ingxenye engenhla yesibuko yenziwe ngezinto zensimbi noma zepulasitiki, futhi ifakwe ngaphakathi, ucingo lwenayiloni olufakwe, ingxenye engezansi yesibuko yenziwe ngocingo oluncane kakhulu lwenayiloni (umdwebo wocingo) njenge ingxenye engezansi yendandatho yesibuko.Ngoba ingxenye engezansi yelensi ayivinjwanga yindilinga yelensi, futhi unqenqema oluwugqinsi lwelensi luzothinta ukubukeka, ngakho-ke idigri iphakeme kakhulu ukukhetha lolu hlobo lohlaka.
I-3, ifreyimu engenasici: ayikho indandatho yesibuko, ibhuloho lekhala lensimbi kuphela kanye nonyawo lwensimbi lwesibuko, i-lens kanye nebhuloho lekhala nonyawo lwesibuko kuxhunywe ngokuqondile ngezikulufa, ngokuvamile ukubhoboza izimbobo ku-lens.Alukho uhlaka olulula futhi olubukekayo kunohlaka olujwayelekile, kodwa amandla ajwayelekile mabi kakhulu kunohlaka olugcwele.Akunconywa ukufanisa lolu hlobo lohlaka lwezingane.Amalunga ahlukahlukene ohlaka kulula ukuwakhulula, ubude besikulufa bukhawulelwe, futhi idigri iphezulu kakhulu.
I-4, Uhlaka lwenhlanganisela: kunamaqembu amabili amalensi kuhlaka lwangaphambili lwefreyimu ehlanganisiwe, eyodwa yayo engavulwa, imvamisa ukusetshenziswa kwangaphakathi nangaphandle.Okujwayelekile iziqeshana zezibuko zelanga, noma iziqeshana zezibuko ze-3D.Okubi ukuthi kunzima ukuthola iziqeshana ezinosayizi ofanayo namafreyimu, ngaphandle uma uthenga isethi yonke.
I-5, ifreyimu yokugoqa: ifreyimu ngokuvamile ingagoqwa ebhulohweni lekhala kanye nomlenze wesibuko ukuze kuncishiswe isikhala esithathwe ifreyimu lapho igcinwa noma ithwalwa;Lolu hlobo lohlaka luvame ukusetshenziselwa izibuko zokufunda.Kulula ukugaya ilensi, kulula ukukhulula uxhumano.
Isinyathelo sesi-4: khetha impahla yohlaka
I-1, ifreyimu yesibuko sepulasitiki: ikakhulukazi ihlukaniswe ngohlaka lomjovo kanye nohlaka lwamapuleti izigaba ezimbili.Uhlaka lokubumba umjovo lulula ngesisindo, kulula ukulucubungula, lubunjwa kahle, kodwa lulula ukuwohloka, ukungaqini kahle namandla okucindezela;Uhlaka lwamapuleti lunombala ogqamile, amandla aqinile okuqina namandla acindezelayo, kodwa inqubo yokukhiqiza iyinkimbinkimbi kakhulu.
I-2, ifreyimu yesibuko sensimbi: izici zayo ziyi: eqinile, engasindi, enhle, isitayela senoveli, izinhlobonhlobo.Iningi liyingxubevange, kanti amanye angafiphala kuye ngenqubo yokucwenga.Ngaphezu kwalokho, kukhona amafreyimu we-titanium ahlanzekile, kanye namafreyimu e-alloy yenkumbulo, angezwani, ahlala isikhathi eside futhi amelana nokugqwala.
3, uhlaka lwezinto ezixubile: ikakhulukazi ezenziwe ngensimbi nepulasitiki.Ukuhlanganisa izinzuzo zepulasitiki nensimbi, kuzuzwe okuhle nokulula, iningi liyipulasitiki yefreyimu, umlenze wesibuko sensimbi, odume kakhulu eminyakeni emibili edlule.
I-4, ifreyimu yezinto zemvelo: igobolondo elivamile lofudu, izimpondo zokhuni nezimpondo zezilwane, njll. Ihlobisa ngaphezu kokusebenza, i-hawksbill kulula ukuphuka, izinkuni zibola kalula, futhi uhlaka lwamapulangwe lulula ukugqoka isikhumba.Ukubulawa kwezimfudu zama-hawksbill manje sekunqatshelwe futhi akuvamile.
Isinyathelo sesi-5: Yizame
I-1, Induduzo: Uhlaka lwezibuko ludinga ukuzizwa lukhululekile ngemva kokugqoka, ngaphandle kokucindezela izindlebe, ikhala noma amathempeli, futhi ngeke lukhululeke kakhulu.
2, ibanga leso, njengoba negama lisho, ibanga eliphakathi kwelensi neso, ngokuvamile liyi-12MM.Uma amehlo eqhelelene kakhulu, abantu abane-myopia bangase bangaboni kahle, futhi abantu abane-hyperopia bangase babe ne-diopter ephakeme kakhulu.Okuphambene kuyiqiniso lapho amehlo esondelene kakhulu.Kungcono ukhethe ifreyimu yesibuko enekhala lensimbi yokubamba, ingalungisa ubude.
3, ebangeni lokuzikhethela, intandokazi yabo iyona ebaluleke kakhulu.
Ngenhla UKUKHETHA izinyathelo ezinhlanu zohlaka lwezibuko, uhlaka lwezibuko olufanele lungasiza futhi ukulawula i-myopia.Iziguli ezivamile ze-myopia kufanele zishintshwe njalo eminyakeni emibili ngokuvamile izibuko ze-myopia: enye "i-update", 2 iwukuba ulungise izinga.
