Njengoba ilanga likhanya kakhulu ehlobo, ukuphuma ngaphandle kuvame ukubangela ukusabela okuzenzakalelayo kokubuka amehlo.izibuko zelangamuva nje zibe yindawo yokukhula kwemali engenayo ekhulayo embonini yokuthengisa izibuko, kuyilapho amalensi e-photochromic ehlala eyisiqinisekiso esiqinile sokuthengiswa kwehlobo. Imakethe kanye nokwamukelwa kwabathengi kwamalensi e-photochromic kuvela esitayeleni sawo, ukuvikelwa kokukhanya, kanye nokufaneleka kokushayela phakathi kwezinye izidingo ezahlukahlukene.
1. Kungani ukuvikelwa kokubona kuyadingeka?
Ukukhanya kwe-ultraviolet kungahlukaniswa kalula kube yi-UVA, i-UVB, kanye ne-UVC:
I-UVC inobude besikhathi obufushane futhi imuncwa ungqimba lwe-ozone emoyeni, ngakho akuyona inkinga.
I-UVB, ukukhanya kwe-ultraviolet okumaphakathi, kungalimaza amangqamuzana esikhumba ngokusabela kwe-photochemical, okubangela i-erythema kanye nokushiswa yilanga.
I-UVA, ukukhanya kwe-ultraviolet okunamagagasi amade, kubangela ngqo isikhumba ukuba sibe nsundu ngokushesha ngaphandle kokusha, kodwa futhi kuholela ezimweni ezifana ne-keratitis.
Ebusweni boMhlaba, ukukhanya kwe-ultraviolet okunamaza amade kwenza u-97% wokuchayeka ku-UV. Ngakho-ke, ukuvikelwa ku-UVA kanye ne-UVB empilweni yansuku zonke kubalulekile.
Enye ingozi ukukhanya okukhanyayo. Esimweni sezulu esicacile, ikakhulukazi ehlobo, ukukhanya okukhanyayo akugcini nje ngokuthinta ukucaca kokubona kodwa futhi kubangela ukukhathala kwamehlo.
Njengoba kunikezwe lesi sizinda, ukubaluleka kokukhetha amalensi e-photochromic ahlinzeka kokubili ukulungiswa kokubona kanye nokuvikelwa kokukhanya kusobala.
2. Ingabe wonke umuntu angagqokaamalensi e-photochromic?
Okokuqala, qaphela amaqembu alandelayo angafaneleki amalensi e-photochromic:
Izingane ezincane ezine-myopia (ezingaphansi kweminyaka engu-6 ubudala) ezinamehlo asakhula zingase zithinteke ukuguguleka kwesikhathi eside.
Abantu abane-glaucoma badinga ukukhanya okukhulu. Ukugqoka izibuko zelanga kunciphisa ukukhanya, okungakhulisa amehlo, kwandise ukucindezeleka kwamehlo, futhi kubangele ubuhlungu.
Abantu abane-optic neuritis, njengoba begqoke amalensi e-photochromic, bangenza ukuvuvukala kube kubi kakhulu ngenxa yokungahambi kahle kwemizwa.
Ukukhanya kwe-UV kuhlala kukhona, kungakhathaliseki ukuthi isizini noma isimo sezulu sinjani. 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 yokuqala yendawo ezungezile, okunciphisa ngempumelelo ukuqina kokukhanya. Amalensi ampunga ahlinzeka ngokumunca okulinganiselayo kuzo zonke izinhlobo, ngakho izinto zibonakala zimnyama kodwa zingenakho ukuphambuka okukhulu kombala, okunikeza umbono ongokoqobo wemvelo. Ngaphezu kwalokho, umpunga umbala ongathathi hlangothi ofanele wonke umuntu, okwenza uthandwe kakhulu.
4. Izinzuzo zesisekelo esicacile,amalensi e-photochromic aphikisana nokukhanya okuluhlaza okwesibhakabhaka?
Ifanele izimo zokuphila ezahlukahlukene, ishintshashintsha kalula phakathi kwangaphakathi nangaphandle, isebenza ngezinjongo ezimbili.
Ngaphakathi/ebusuku zicacile futhi zicacile, ngaphandle ziba mnyama, zinikeza isivikelo esikabili emisebeni ye-UV kanye nokukhanya okuluhlaza okwesibhakabhaka okuyingozi, okuqeda ukukhathala.
Ubuchwepheshe obuhle kakhulu bokushintsha ifilimu buqinisekisa ukuguquka kombala okusheshayo nokuzinzile; ubuchwepheshe bokukhanya oku-nano okulwa noluhlaza okwesibhakabhaka bugcina amalensi ecacile futhi engabi phuzi, okuqinisekisa ukubona okukhululekile.
Njengoba isisho sithi, "Ukuze wenze umsebenzi omuhle, umuntu kumele aqale alole amathuluzi akhe." Ukusekelwa kwezinto ezibonakalayo: amasampula e-photochromic, izinto zokuhlobisa, kanye namaphosta e-lightbox kusiza ekukhuthazeni amalensi e-photochromic.
Induduzo, ukuvikelwa, kanye nokulula yizinto ezintathu okudingeka ziqiniswe ngokuphindaphindiwe lapho kukhulunywa nabathengi.
5. Zinesisekelo esicacile,amalensi e-photochromic aphikisana nokukhanya okuluhlaza okwesibhakabhakaifaneleka kakhulu ekufakeni isitokisi?
Esinye sezihloko ezishisa kakhulu empilweni yamehlo njengamanje ukuvikelwa kokukhanya okuluhlaza okwesibhakabhaka, kanye namalensi asebenzayo anamakhono okukhanya okulwa nokukhanya okuluhlaza okwesibhakabhaka athandwa kakhulu ngabathengi. Umonakalo we-UV uyinkinga yonyaka wonke kodwa ubonakala kakhulu ezinyangeni zasehlobo ezishisayo, ngakho-ke isidingo samalensi e-photochromic sihlala isikhathi eside.
Nakuba amalensi e-photochromic etholakala ngemibala ehlukahlukene, amalensi ampunga afaneleka kakhulu emasokisini. Ngaphandle, umbala ompunga ojulile uyinto ekhululekile kakhulu emehlweni; ahambisana kahle nanoma yiluphi uhlaka lwezibuko zamehlo, okwenza kube ukukhetha okuguquguqukayo kwemibala ye-photochromic.
Njengoba kukhethwa ama-refractive indices amaningi, amalensi e-photochromic index angu-1.56 kanye no-1.60 athengiswa kakhulu ezitolo. Ukwandisa isilinganiso sokuthengisa samalensi e-Safety Guard 1.60 clear-base anti-blue light photochromic akusizi nje kuphela ukwandisa inani elimaphakathi loku-oda kodwa futhi kunezinzuzo ezicacile ezenza kube lula ukuthengiselana. Ukuze uthole izinqubomgomo ezengeziwe zempahla kanye nokusekelwa kwangemva kokuthengisa kwamalensi e-Safety Guard clear-base anti-blue light photochromic, sicela uxhumane nommeleli wezokuthengisa.
6. Imisebenzi yemibala ehlukeneamalensi e-photochromic?
| Umbala wetiye | Ithuthukisa ngempumelelo umehluko nokucaca kokubona, isebenza kahle ezimweni ezingcolile kakhulu noma ezinenkungu, futhi iyisinqumo esifanele sabashayeli kanye neziguli ezithola imithi kadokotela ephezulu. |
| Okumpunga | Kunciphisa ngempumelelo ukukhanya, ukubuyiselwa kombala okuphezulu, umbono ongokoqobo, ofanele bonke abasebenzisi. |
| Opinki/Ophuzi | Ihlunga ukukhanya okulahlekile, ivimbele ukukhanya okunamandla futhi ikuthambise, ingasiza futhi ekuphumuleni nasekunciphiseni ukucindezeleka, futhi iyisengezo semfashini sezingubo zansuku zonke zabesifazane. |
| Okuluhlaza okwesibhakabhaka: | Imunca kahle ukukhanya okungabonakali okubonakala emehlweni, isiza ekunciphiseni ukukhathala kokubona. Kuyindlela ekhethwayo yokuphuma ogwini. |
| Ophuzi | Kuthuthukisa ukungafani kokubona ezindaweni ezinenkungu kanye nasebusuku, okwenza umbono ucace. Kungasetshenziswa njengezibuko zokubona ebusuku, ikakhulukazi ezifanele abashayeli. |
| Okuluhlaza okotshani | Kwandisa inani lokukhanya okuluhlaza okufinyelela emehlweni, kunciphisa ukusetshenziswa kakhulu kwamehlo, kufaneleka kubantu abakhathele amehlo. |
Uma ukhetha imibala enconyiwe, cabangela izici zokusebenza kwamalensi, injongo yezibuko, kanye nokukhetha kombala kwekhasimende.
