Qinisekisa ukuthi unake ulwazi lwama-lens wezibuko. Ngokuvamile eyenziwe ngu:
- I-Glass. Ukungahleleki kwalokhu okubonakalayo kungukuthi kunesibindi nokuqina. Ngakho-ke, aziphephile amehlo. Izinzuzo: ukukhanya okuphezulu kanye nezakhiwo ezinhle kakhulu zokukhanya, ukukhipha kancane.
- Amaplastiki. Lawa ama-acrylic, polycarbonate nama-polyurethane lens. Amalazi anama-lens anjalo alula, ahlala njalo, aphethwe yingozi-ephephile, cishe ungadluli imisebe ye-ultraviolet neye-infrared. Noma kunjalo, ama-scuffs kanye nezikhalo zivela ngokushesha kubo.
Indlela yokukhetha izibuko zamasifazane?
Kunconywa ukuba ukhethe izibuko ezihlunga mayelana ne-99-100% yemisebe ye-UV enobubanzi obungama-400 nm (kufanele ibhalwe nge-UV 400). Kodwa kaningi kakhulu kunezibuko ezibukwayo nge-index yezokuvikela ye-UV 380, ebuyisela ama-95% wemisebe ye-ultraviolet. Kulesi simo, ama-lenses amnyama angabonakali kahle i-ultraviolet ngaphezu kokukhanya.
Ngezinye izikhathi kungenye indlela - abafundi abavela kumalensi amnyama banda kakhulu, futhi ukukhanya okungaphezulu kwe-ultraviolet kufinyelela emehlweni.
Ukukhanya okubonakalayo (okubonwa ngamehlo omuntu) kudluliselwa ama-lens elanga kuze kufike ku-80-100% (engenambala futhi enemibala emincane) kuya ku-3-8% (ngokufiphala kakhulu).
Kuye kulezi zinkomba, khetha amaphuzu ngaphansi kwezimo zezulu, lapho uzozigqoka khona.
Ukukhethwa kwemibala yezibuko ezibukwayo kuncike ekuthandweni kwakho kanye nemfashini yakho. Kodwa-ke, cabanga ukuthi imibala eluhlaza neyomnyama yama-lens ayiphambisani nokubona kombala, futhi insabala, iluhlaza, i-orange ihlanekezela.
Amanye amafomu nezinhlobo zezibuko zokukhanya
Kunezinhlobo eziningi zezibuko, kuye ngokuthi ifomu nenhloso.
Ngomuntu ngamunye - uhlobo oluthile lwezibuko lukhethiwe. Ukuze ufanise ukuma kobuso bakho, hlanganisa izinwele ngemuva bese uzibuka esibukweni noma uthathe isithombe. Ngakho ungaba cishe ukulinganisa uhlaka lwaso: nxazonke, oval, square, triangular.
- Ama-aviators ama-glass, noma amaconsi , - isifanekiso esinama-large lens-shaped in frame encane yensimbi. Ekuqaleni zenzelwe abashayeli bezindiza, lokhu kuchaza igama. Manje izibuko ezinjalo zibhekwa njengesimodeli esiyisisekelo esiyingqayizivele, esakhiwa ngezindlela ezihlukahlukene cishe cishe bonke abakhiqizi. Inzuzo ye-aviators ukuthi bazosondela kunoma yimuphi owesifazane ngaphansi kwanoma yikuphi izingubo.
- Izibuko ezisizungezile (isitayela se-retro) sizobukeka kahle ebusweni befomu lesikwele, tk. bazobukeka behlise imizila ebukhali ye-chin kanye ne-cheekbones. Kulezi zibuko, ikakhulukazi ezinkulu, amantombazane anomumo wesimo se-oval azobukeka emuhle. Leli fomu lomsindo litholakala ngokuhlukahluka okuhlukahlukene: kuhlaka olujulile noluncane, olunezimpawu ezimnyama noma ezibala. Zama ukuhlola ngezibuko endaweni ejikelezayo, ikakhulukazi kusukela izibuko zokukhanya zaleli fomu ziphinde zifake imfashini.
- Ezikhathini zokubukela ngaphandle komgqomo, izingalo zifakwe ngqo kuma-lens. Abanikazi bekhanda elincane bayelulekwa ukuba bakhethe izibuko, engxenyeni engenhla engenawo uhlaka. Abesifazane abanekhanda elibanzi banekhono lokubufihla ngezibuko ngaphandle kohlaka oluphansi.
- Ngezemidlalo, khetha izibuko zezemidlalo ezikhethekile. Kumele zikhululeke, ziqine, zikhanyise, zinikeze umthunzi odingekayo, futhi zivikele amehlo emiphumeleni yomoya, uthuli, amanzi. Ngakho izibuko zezemidlalo ziphoqelekile ukuba zinikeze ukubuyekezwa okwesikhashana. Kwezinye zezemidlalo, ukulungiswa kahle kwamaphoyinti ekhanda kuyadingeka, ngakho-ke kungenziwa nge-strap strap esikhundleni sezingqinamba.
