Imibuzo Evame Ukubuzwa Mayelana Nezibuko Zamehlo Ezinombala Kadokotela
Izibuko zamehlo ezinombala ziyi-lens kadokotela ene- umbala ohlala njalo noma oguquguqukayoUmbala ungahluka kusukela kumibala ekhanyayo kakhulu yemfashini yansuku zonke kanye nenduduzo kuya kumibala emnyama eyenzelwe ukusetshenziswa ngaphandle.
Ngokungafani nezibuko zelanga ezijwayelekile zikadokotela—ezivame ukuvimba ukukhanya okubonakalayo okungu-70% kuya ku-80%—izibuko zikadokotela ezinombala zingahluka kusukela kokukhanya okucashile, okukhanyayo (ubumnyama obungu-10–20%) kuya kokukhanya okumnyama okugcwele, kanye nokukhanya okugqamile. Zihlanganisa ukulungiswa kwamandla ngokwezifiso (kwe-myopia, i-hyperopia, i-astigmatism, noma i-presbyopia) nokuhlunga ukukhanya okuqondisiwe.
Akukho mbala owodwa omuhle kakhulu—kuya ngenhloso yakho.
| Umbala ophuzi | Izinzuzo Ezivamile |
|---|---|
| Okumpunga | Ukubona umbala ongathathi hlangothi kanye nokunciphisa ukukhanya okuhle kwenhloso ejwayelekile |
| Insundu/i-Amber | Kuthuthukisa ukugqama futhi kunikeze ukubukeka okufudumele |
| Okuluhlaza okotshani | Inganikeza ukunciphisa ukukhanya okukhululekile ngenkathi igcina umbono wombala wemvelo |
| I-Rose | Ngokuvamile kukhethwa ngenxa yemfashini kanye nenduduzo ebonakalayo |
| Ophuzi/Ophuzi | Kungakhulisa ukugqama okubonakalayo kwezinye izimo zokukhanya okuphansi noma okuguqubele |
| Okuluhlaza okwesibhakabhaka | Ngokuyinhloko ukukhetha imfashini; okungakhethwa kakhulu ukuvikela ilanga |
Akunjalo ngempela. Amalensi kadokotela anombala angase abe nombala omncane futhi ahloselwe ukugqokwa nsuku zonke endlini noma ngaphandle, kuyilapho izibuko zelanga zikadokotela ngokuvamile zinemibala emnyama eyenzelwe ukunciphisa ukukhanya kwelanga okunamandla.
Ukuze uthole ukuvikelwa kwangaphandle, funa amalensi anikeza Ukuvikelwa kwe-UV okungu-100%, kungakhathaliseki ukuthi umbala ubonakala umnyama kangakanani.
Ezimweni eziningi, yebo, kodwa ukutholakala kuncike ezintweni zelensi, amandla kadokotela, ukwakheka kwelensi, kanye nomkhiqizi.
Ukupenda imibala ngokuvamile kuyatholakala ku:
- Amalensi anombono owodwa
- Amalensi e-bifocal
- Amalensi aqhubekayo
- Amalensi anezinkomba eziphezulu
- Amanye amalensi e-photochromic kanye ne-specialty
Imithi ebhalwe kahle kakhulu noma izinto ezithile ezikhethekile zamalensi zingase zibe nezinketho zombala ezilinganiselwe.
Yebo—izibuko ezinombala zingaba kuhle emehlweni akho, kodwa kuya ngohlobo lombala nokuthi uwasebenzisa kanjani.
- Ukuvikelwa kwe-UV: Isici esibaluleke kakhulu. Izibuko zelanga ezine Isivikelo esingu-100% se-UVA/UVB kusiza ukuvikela amehlo akho emisebeni ye-ultraviolet eyingozi.
- Ukukhanya okuncishisiwe: Umbala ompunga, onsundu, noluhlaza unganciphisa ukukhanya futhi wenze umbono wangaphandle ukhululeke kakhudlwana.
- Ukuzwela kokukhanya: Ama-tint athile angasiza abantu abazwela ukukhanya okukhulu noma abazizwa bengakhululekile emehlweni.
- Ukusetshenziswa kwemithi kadokotela: Amalensi kadokotela anombala anganikeza kokubili ukulungiswa kokubona kanye nenduduzo ngaphandle.
- Imibala eluhlaza okwesibhakabhaka: Lokhu kunganciphisa ukucasha okubonakalayo noma ukungakhululeki kwesikrini, kodwa ubufakazi bokuthi kuvimbela ukulimala kwamehlo okuvela ezikrinini zedijithali bulinganiselwe.
Cha. Ubumnyama belensi kanye nokuvikelwa kwe-UV kuyizinto ezihlukile. Ilensi emnyama kakhulu inganciphisa ukukhanya okubonakalayo ngaphandle kokunikeza isivikelo esanele se-UV.
Uma uthenga izibuko ezinombala zikadokotela zokusetshenziswa ngaphandle, qiniseka ukuthi amalensi anikeza Ukuvikelwa kwe-UVAmalensi amnyama angenaso isivikelo esanele se-UV angaba ukukhetha okubi kokuchayeka elangeni isikhathi eside.
Yebo. Umbala okhanyayo ingagqokwa ngaphakathi endlini, ikakhulukazi ngenxa yemfashini noma induduzo yomuntu siqu. Kodwa-ke, imibala emnyama ingenza izindawo zangaphakathi zibe mnyama ngokungadingekile futhi ingathinta indlela obona ngayo ngokucacile.
Ukusetshenziswa kwansuku zonke endlini, abantu abaningi bakhetha i- umbala okhanyayo noma umbala ogqamile.
Yebo, i-tint ngezinye izikhathi ingafakwa ezingilazini ezikhona ezibhalwe udokotela ngemva kokuthenga, kodwa akuvamile ukwenziwa kumalensi osuvele uwagqokile. Iningi lodokotela bamehlo liyavuma ukuthi i-tint yangemva kokuthenga kumalensi asetshenzisiwe noma agqokiwe kunzima, njengoba izinto ezifana ne-polycarbonate noma amalensi ane-anti-reflective coating awamunci udayi ngokulinganayo futhi inqubo ingonakalisa ukwelashwa okukhona.
Kuya ngokuthi umbala unjani.
Ngokushayela emini, imibala empunga, ensundu, noma eluhlaza ngokuvamile zibhekwa njengezinqumo ezisebenzayo ngoba zinganciphisa ukukhanya nokukhanya ngenkathi zigcina ukubonakala okuwusizo.
Imibala emnyama kakhulu noma amalensi athile anombala angase angafaneleki ukushayela, ikakhulukazi ebusuku. Amalensi acwebezelayo ngokuvamile ayathandwa uma ushayela ebusuku.
A ilensi enombala kunciphisa ukukhanya ngokusekelwe kumbala kanye nobuningi bako.
A ilensi ehlanganisiwe isebenzisa isihlungi esikhethekile ukunciphisa izinhlobo ezithile zokukhanya okuvundlile okubonakalayo, okusiza ukulawula ukukhanya okukhanyayo.
Ngokwesibonelo:
- Amalensi anombala: Kuhle ngemfashini, ukunciphisa ukukhanya, kanye nokusetshenziswa okuvamile ngaphandle
- Amalensi ahlanganisiwe: Iwusizo kakhulu emanzini, eqhweni, emigwaqweni, nakwezinye izindawo ezikhanyayo
Ukuhlukaniswa kwemibala kungahlanganiswa nokulungiswa kwemithi kadokotela kanye nokushintsha umbala.
Yebo, amalensi anombala ngokuvamile aphephile futhi afanele izingane uma esetshenziselwa izidingo ezithile njengokuvikela ilanga, ukuzwela ukukhanya, noma ukunciphisa ukukhanya. Kodwa-ke, umbala nobumnyama bombala kufanele kukhethwe ngokusekelwe emisebenzini yengane kunokuthi kubhekwe imfashini kuphela. Abazali kufanele babeke phambili:
- Ukuvikelwa okufanele kwe-UV
- Izinto zelensi ezingamelani nokushayisana
- Ukulingana okufanele kohlaka
- Ukuqina kwelensi
- Izidingo zangempela zomntwana ezibonakalayo
I-tint eyenziwe ngobuchwepheshe ngokuvamile yenzelwe ukuhlala izinzile, kodwa ukuchayeka isikhathi eside elangeni, ekushiseni, kumakhemikhali, nasekuhlanzweni okungafanele kungathinta amanye amalensi noma izimbozo.
Ukuqina kombala kuncike endleleni yokufaka umbala kanye nezinto zelensi.
Ngezinye izikhathi, kodwa hhayi njalo. Amanye amalensi angacutshungulwa kabusha noma ashintshwe, kodwa ukususa umbala ophuzi kulensi kadokotela eqediwe kungase kungavezi umphumela ocacile.
Uma ucabanga ukuthi ungase ufune imibala ehlukene esikhathini esizayo, ngokuvamile kungcono uku-oda amalensi kadokotela ahlukene.
Cha.
Amalensi anombala ngokuvamile zinombala oqinile.
Amalensi e-Photochromic iba mnyama ngokuzenzakalelayo uma ivezwa ku-UV noma ezimweni ezithile zokukhanya bese ikhanya ngaphakathi endlini.
Amalensi e-photochromic alungele abantu abavame ukuhamba phakathi kwezindawo zangaphakathi nezangaphandle, kodwa awamnyama njalo njengezibuko zelanga ezinikezwe udokotela lapho ilanga likhanya kakhulu.
Ezimweni eziningi, yebo. Kuye ngomkhiqizi welensi kanye nelabhorethri, amalensi kadokotela anombala angatholakala nalokhu:
- Izembozo ezivimbela ukukhanya
- Izembozo ezingaklwebhi
- Ukuvikelwa kwe-UV
- Izembozo ezivimba amanzi namafutha
- Izimbozo zesibuko
- Ukwehlukaniswa
Ukuhambisana kuyahlukahluka kuye ngezinto zelensi kanye nenqubo yokukhiqiza.
Izibuko zamehlo ezinombala kadokotela zinikeza inhlanganisela ye ukulungiswa kombono, induduzo, ukuvikelwa kwelanga, kanye nesitayela somuntu siqu. Ukukhetha okungcono kuncike kumithi yakho kadokotela, indlela yokuphila, indawo ehlosiwe, nokuthi ngabe udinga izici ezifana nokwehlukanisa noma ukusebenza kwe-photochromic.
