Ngokuphathelene nohlaka lombukwane ngokwalo, luyizici ezintathu: ikhwalithi yezinto ezibonakalayo, imininingwane yobuciko kanye nomklamo.
Material: ikakhulukazi ihlukaniswe metal, plastic kanye nezinye izinto.Insimbi engcono kakhulu i-titanium, i-titanium ehlanzekile, i-titanium B noma i-titanium alloy.I-Titanium inenzuzo yokuba ilula ngokuqhathaniswa, izinzile futhi ingabi ne-oxidized kalula.Akulula ukushisela ngemva kokuba i-solder iphukile.Ezinye izibuko zensimbi empeleni zinhle, ikakhulukazi insimbi engagqwali, zifakwe ugesi futhi zicutshungulwa kabusha.Ipulasitiki iwuhlobo oluvamile lwepuleti, le nto iyasinda, ithungwa, imnene, inemibala emihle, akulula ukuyixebula, i-hinge yensimbi enganele ilimaza kalula.Enye impahla yepulasitiki evamile i-TR90, esetshenziswa ezingilazini eziningi ezibukeka zikhanya futhi ezicwebezelayo kumadrama aseKorea.Kodwa-ke, i-TR90 kulula ukuyicwecwa nokuphuka.Ezinye izinto zifaka ukhuni noqalo, kodwa azijwayelekile.
Imininingwane yenqubo: ungalalela ukuthi umsindo wokuvula nokuvala wehinge ushelela yini, bheka isiphetho sefreyimu yesithombe, noma ngabe indawo yokucweba iyacwebezela, i-LOGO iqoshwe noma ukuphrinta kwesikrini sikasilika.Uma ucabanga ukuthi ngeke ukhombe, ungaya esibhedlela samehlo ochwepheshe ukuze ukhethe amafreyimu omkhiqizo.
Idizayini: kufaka phakathi umqondo womkhiqizo, isitayela, isitayela nombala, iqoqo ngalinye lihumusha isitayela esihlukile, lingakhethwa ngokuya ngobuntu babo, isimo sengqondo kanye nesitayela sokugqoka.
Khetha ifreyimu ye-eyeglass ngaphezu kwalokho, yimaphi amaphuzu okudingeka unake?
Ngokunethezeka: Amafreyimu adinga ukuzizwa ekhululekile ngemva kokufakwa kwawo, angacindezeli izindlebe, ikhala noma amathempeli, futhi angaxegi kakhulu.
Ibanga lelensi: Njengoba igama lisho, ibanga eliphakathi kwelensi neso, ngokuvamile liyi-12MM.Uma i-lens ikude kakhulu, abantu abane-myopia bangase bangaboni kahle, futhi abantu abane-hyperopia bangase babe ne-diopter eningi kakhulu.Okuphambene kuyiqiniso uma ilensi iseduze kakhulu.
I-Rake Angle: ngaphansi kwezimo ezijwayelekile ku-8-12 degrees, uma i-rake Angle inkulu kakhulu, umkhawulo ophansi we-lens ungase uthinte ubuso, kuyoba nzima ukubona eduze, kungase futhi kubangele ibanga le-lens likhulu kakhulu.Uma i-engeli yeraki incane kakhulu, kuzoholela ekuncipheni komkhakha wokubona kude kanye nobunzima bokubona eduze.Ngesikhathi esifanayo, i-rake angle enkulu kakhulu noma encane kakhulu ayinhle kakhulu.
Ububanzi befreyimu: ukusondela kobubanzi bejiyomethri kanye nebanga lomfundi lohlaka, kuba ngcono, ukuze kugcinwe indawo enembayo kakhulu emkhakheni wokubona, futhi kuncishiswe ukuwohloka kanye nomehluko wezinto ezizungezile.Ngakho-ke bafuna ukufanisa izibuko ezinkulu ze-myopia iziguli ezidinga ukunaka, ukuphishekela imfashini ngesikhathi esifanayo kungase kube umhlatshelo izinga lombono, izimpawu ezivame kakhulu ukugqoka izibuko ngesiyezi, ukuguqulwa kombono we-peripheral.
