Ngokukhanya kwelanga okushubile kwasehlobo, ukuphuma ngaphandle kuvame ukubangela ukucwayiza okuzenzakalelayo. Incwadi kadokotelaizibuko zelangamuva nje abe yindawo yokukhula kwemali engenayo ekhulayo embonini yokudayisa izingubo zamehlo, kuyilapho amalensi e-photochromic ehlala eyisiqinisekiso esiqinile sokuthengiswa kwehlobo. Imakethe nokwamukela kwabathengi amalensi e-photochromic kubangelwa isitayela sawo, ukuvikela ukukhanya, nokufaneleka kokushayela phakathi kwezinye izidingo.
1.Kungani ukuvikela okubukwayo kuyadingeka?
Ukukhanya kwe-Ultraviolet kungamane kuhlukaniswe kube i-UVA, UVB, ne-UVC:
I-UVC inobude obufushane begagasi futhi imuncwa ungqimba lwe-ozone emkhathini, ngakho akuyona into ekhathazayo.
I-UVB, ukukhanya kwe-ultraviolet kwamagagasi amaphakathi, ingalimaza amangqamuzana esikhumba ngokusabela kwamakhemikhali ezithombe, kubangele i-erythema nokushiswa yilanga.
I-UVA, ukukhanya kwe-ultraviolet kwamagagasi amade, ibangela ngokuqondile isikhumba ukuba sibe mnyama ngokushesha ngaphandle kokushiswa, kodwa futhi iholela ezimeni ezifana ne-keratitis.
Emhlabeni, ukukhanya kwe-ultraviolet kwamagagasi amade kwenza u-97% wokuchayeka kwe-UV. Ngakho-ke, ukuvikela ngokumelene ne-UVA ne-UVB ekuphileni kwansuku zonke kubalulekile.
Enye ingozi ukuxhopha. Esimweni sezulu esicacile, ikakhulukazi ehlobo, ukukhanya okukhanyayo akuthinti nje ukucaca kombono kodwa futhi kubangela ukukhathala kwamehlo.
Ngokunikezwa kwalesi sizinda, ukubaluleka kokukhetha amalensi e-photochromic anikeza kokubili ukulungiswa kokubona nokuvikela ukukhanya kuyabonakala.
2.Ngabe wonke umuntu angagqokaama-lens photochromic?
Okokuqala, qaphela amaqembu alandelayo angawafanele amalensi e-photochromic:
Izingane ezincane ze-myopic (ezingaphansi kweminyaka engu-6 ubudala) amehlo azo asathuthuka zingase zithinteke ngokuguga isikhathi eside.
Abantu abane-glaucoma badinga ukukhanya okukhanyayo. Ukugqoka izibuko zelanga kunciphisa ukukhanya, okunganweba abafundi, kukhulise umfutho wamehlo, futhi kubangele ubuhlungu.
Abantu abane-optic neuritis, njengoba ukugqoka amalensi e-photochromic kungakhuphula ukuvuvukala ngenxa yokungahambi kahle kwemizwa.
Ukukhanya kwe-UV kuhlala kukhona, kungakhathaliseki isizini noma isimo sezulu. Ngaphandle kwamaqembu okukhulunywe ngawo ngenhla, izibuko ze-photochromic zifanele wonke umuntu.
3.Kungani amalensi ampunga evame kakhulu emakethe?
Amalensi ampunga angamunca i-infrared kanye nama-98% emisebe ye-UV. Inzuzo enkulu yamalensi ampunga ukuthi awashintshi imibala yasekuqaleni yendawo ezungezile, ehlisa ngempumelelo ukukhanya kokukhanya. Amalensi ampunga anikeza ukumuncwa okunokulinganisela kuzo zonke izibukeli, ngakho izinto zibonakala zimnyama kodwa ngaphandle kokuhlanekezelwa okuphawulekayo kombala, enikeza ukubuka kweqiniso kwemvelo. Ukwengeza, okumpunga kuwumbala ongathathi hlangothi ofanele wonke umuntu, okwenza udume kakhulu.
4. Izinzuzo zesisekelo esicacile,anti-blue ukukhanya photochromic lens?
Ifanele izimo zempilo ezahlukahlukene, ukushintsha ngaphandle komthungo phakathi kwasendlini nangaphandle, kufeza izinjongo ezimbaxambili.
Ngaphakathi/ebusuku zicacile futhi zisobala, ngaphandle ziba mnyama, zinikeza isivikelo esikabili emisebeni ye-UV nokukhanya okuluhlaza okulimazayo, ekhulula ukukhathala.
Ubuchwepheshe obuhle kakhulu bokushintsha ifilimu buqinisekisa ukushintshwa kombala okusheshayo futhi okuzinzile; ubuchwepheshe bokukhanya kwe-nano anti-blue bugcina amalensi ecacile futhi engephuzi, iqinisekisa ukubona kahle.
Njengoba isisho sithi, "Ukuze wenze umsebenzi omuhle, umuntu kufanele aqale alole amathuluzi akhe." Usekelo lwezinto ezibonakalayo: amasampula e-photochromic, ama-props, namaphosta e-lightbox asiza ekuthuthukiseni amalensi e-photochromic.
Ukunethezeka, ukuvikela, kanye nokunethezeka amaphuzu amathathu adinga ukuqiniswa ngokuphindaphindiwe lapho kuxhunywana nabathengi.
5.Isisekelo esicacile,anti-blue ukukhanya photochromic lensifaneleka kakhulu isitoko?
Esinye sezihloko ezishisa izikhotha kwezempilo yamehlo okwamanje ukuvikela ukukhanya okuluhlaza okwesibhakabhaka, namalensi asebenzayo anamandla okukhanya okuluhlaza okwesibhakabhaka athandwa kakhulu kubathengi. Ukulimala kwe-UV kuwukukhathazeka konyaka wonke kodwa kugqama ikakhulukazi ezinyangeni ezishisayo zasehlobo, ngakho isidingo samalensi e-photochromic singokwesikhathi eside.
Nakuba amalensi e-photochromic etholakala ngemibala ehlukahlukene, amalensi ampunga afaneleka kakhulu esitokisini. Ngaphandle, okumpunga okujulile kuwumbala othokomele kakhulu wamehlo; zihambisana nemfashini nanoma yiluphi uhlaka lwengilazi yamehlo, okubenza babe ukukhetha okuhlukahlukene kwemibala ye-photochromic.
Uma kunikezwe ukukhetha kwama-indices amaningi e-refractive, amalensi e-refractive index photochromic angu-1.56 nangu-1.60 athengiswa kakhulu ezitolo. Ukwenyusa isilinganiso sokuthengisa se-Safety Guard 1.60 amalensi e-anti-blue light photochromic ahlanzekile akusizi nje ukukhulisa inani le-oda elimaphakathi kodwa futhi kunezinzuzo ezicacile ezisiza ukuthengiselana. Ukuze uthole izinqubomgomo zohlu lwezimpahla ezengeziwe kanye nosekelo lwangemva kokuthengiswa kwamalensi e-Safety Guard e-anti-blue photochromic ukukhanya, sicela uthintane nommeleli wezentengiso.
6.Imisebenzi yemibala ehlukene yeama-lens photochromic?
| Umbala Wetiye | Ithuthukisa ngempumelelo ukugqama okubonakalayo nokucaca, isebenza kahle ezimeni ezingcoliswe kakhulu noma ezinenkungu, futhi iyinketho ekahle yabashayeli neziguli ezinemithi ephezulu. |
| Okumpunga | Yehlisa ngempumelelo ukukhanya, ukubuyiselwa kombala ophezulu, umbono wangempela wokuphila, ofanele bonke abasebenzisi. |
| Opinki/Onsomi | Izihlungi zokukhanya okunhlanhlathayo, zivimba ukukhanya okuqinile futhi zikuthambisa, zingasiza futhi ukuphumula futhi zidambise ingcindezi, futhi ziyinsizakalo yemfashini yezingubo zansuku zonke zabesifazane. |
| Okuluhlaza okwesibhakabhaka: | Imunca ngokuphumelelayo ukukhanya okubonakala emehlweni, kusize ekudambiseni ukukhathala okubukwayo. Kuyinketho ekhethwayo yokuvakasha olwandle. |
| Okuphuzi | Ithuthukisa ukugqama okubonakalayo ezindaweni ezinenkungu nakusihlwa, kwenze ukubona kucace. Ingasetshenziswa njengezibuko zokubona ebusuku, ezilungele ikakhulukazi abashayeli. |
| Okuhlaza | Yandisa inani lokukhanya okuluhlaza okufinyelela emehlweni, ikhulula ukusebenzisa amehlo ngokweqile, ifanele abantu abanokukhathala kwamehlo. |
Lapho ukhetha imibala enconyiwe, cabangela izici zokusebenza zamalensi, injongo yezibuko, kanye nezinketho zombala zekhasimende.
