Ngenxa yokukhanya kwelanga okukhulu ehlotyeni, ukuphuma ngaphandle kudla ngokubangela ukuba umntu abonakale elele ngokuzenzekelayo.iiglasi zelangaKutshanje ziye zaba yindawo yokukhula kwengeniso ekhulayo kushishino lokuthengisa ngezibuko, ngelixa iilensi ze-photochromic zihlala zisisiqinisekiso esiqinileyo sentengiso yasehlotyeni. Imarike kunye nokwamkelwa kwabathengi kweelensi ze-photochromic kuvela kwisitayile sazo, ukhuseleko lokukhanya, kunye nokufaneleka kokuqhuba phakathi kwezinye iimfuno ezahlukeneyo.
1. Kutheni ukhuseleko lokubona luyimfuneko?
Ukukhanya kwe-ultraviolet kunokwahlulwahlulwa kube yi-UVA, i-UVB, kunye ne-UVC:
I-UVC inobude obufutshane bomsinga kwaye ifunxwa ngumaleko we-ozone emoyeni, ngoko ke ayisiyongxaki.
UVB, ukukhanya kwe-ultraviolet okuphakathi, kungonakalisa iiseli zesikhumba nge-photochemical reactions, okubangela i-erythema kunye nokutsha lilanga.
I-UVA, ukukhanya kwe-ultraviolet okunamaza amade, kubangela ngokuthe ngqo ukuba ulusu lube mnyama ngokukhawuleza ngaphandle kokutsha, kodwa ikwakhokelela kwiimeko ezifana ne-keratitis.
Kumphezulu woMhlaba, ukukhanya kwe-ultraviolet okunamaza amade kwenza i-97% yokuvezwa yi-UV. Ngoko ke, ukukhuselwa kwi-UVA kunye ne-UVB kubomi bemihla ngemihla kubalulekile.
Enye ingozi kukuqaqamba. Kwimozulu ecacileyo, ingakumbi ehlotyeni, ukuqaqamba akuchaphazeli nje kuphela ukucaca kokubona kodwa kukwabangela nokudinwa kwamehlo.
Ngenxa yesi sizathu, ukubaluleka kokukhetha iilensi ze-photochromic ezibonelela ngokulungiswa kokubona kunye nokukhuselwa kokukhanya kuyabonakala.
2. Ngaba wonke umntu anganxibaiilensi ze-photochromic?
Okokuqala, qaphela amaqela alandelayo angafanelekanga kwiilensi ze-photochromic:
Abantwana abancinci abanengxaki yokungakwazi ukubona kakuhle amehlo (abangaphantsi kweminyaka emi-6 ubudala) abanamehlo asakhulayo banokuchaphazeleka kukuguguleka kwexesha elide.
Abantu abane-glaucoma badinga ukukhanya okuqaqambileyo. Ukunxiba iiglasi zelanga kunciphisa ukukhanya, okunokwandisa amehlo, konyuse uxinzelelo lwamehlo, kubangele intlungu.
Abantu abane-optic neuritis, njengoko ukunxiba iilensi ze-photochromic kunokubangela ukudumba okungaphezulu ngenxa yokungahambi kakuhle kwemithambo-luvo.
Ukukhanya kwe-UV kuhlala kukho, nokuba lixesha lonyaka okanye imozulu injani. Ngaphandle kwamaqela akhankanyiweyo apha ngasentla, iiglasi ze-photochromic zifanelekile kuye wonke umntu.
3.Kutheni iilensi ezingwevu zixhaphake kakhulu kwimarike?
Iilensi ezingwevu zinokufunxa i-infrared kunye ne-98% yemitha ye-UV. Inzuzo ephambili yeelensi ezingwevu kukuba azitshintshi imibala yokuqala yendawo engqongileyo, nto leyo enciphisa ngokufanelekileyo ukukhanya. Iilensi ezingwevu zibonelela ngokufunxa ngokulinganayo kuzo zonke ii-spectrum, ngoko ke izinto zibonakala zimnyama kodwa zingenambala ugqithisileyo, nto leyo enika umbono ochanekileyo. Ukongeza, umbala ongwevu ngumbala ongathathi cala ofanele wonke umntu, nto leyo eyenza ukuba uthandwe ngakumbi.
4. Iingenelo zesiseko esicacileyo,iilensi ze-photochromic ezikhanyayo ezichasene noluhlaza okwesibhakabhaka?
Ifanelekile kwiimeko ezahlukeneyo zobomi, itshintshatshintsha ngaphandle komthungo phakathi kwendlu nangaphandle, isebenzela iinjongo ezimbini.
Ngaphakathi/ebusuku zicacile kwaye azibonakali, ngaphandle ziba mnyama, zibonelela ngokhuseleko oluphindwe kabini kwimitha ye-UV kunye nokukhanya okuluhlaza okwesibhakabhaka okuyingozi, okunciphisa ukudinwa.
Itekhnoloji egqwesileyo yokutshintsha ifilimu iqinisekisa utshintsho olukhawulezayo noluzinzileyo lombala; itekhnoloji yokukhanya okuchasene noluhlaza okwesibhakabhaka igcina iilensi zicacile kwaye zingabi tyheli, iqinisekisa ukubona okukhululekileyo.
Njengoko intetho isithi, "Ukuze wenze umsebenzi olungileyo, umntu kufuneka aqale alole izixhobo zakhe." Inkxaso yezinto eziphathekayo: iisampuli ze-photochromic, izixhobo, kunye neepowusta ze-lightbox zinceda ekukhuthazeni iilensi ze-photochromic.
Intuthuzelo, ukhuseleko, kunye nokulula zizinto ezintathu ekufuneka ziqiniswe rhoqo xa kunxityelelwana nabathengi.
5. Zicacile,iilensi ze-photochromic ezikhanyayo ezichasene noluhlaza okwesibhakabhakaifanelekile ngakumbi kwisitokhwe?
Enye yezona zihloko zishushu kakhulu kwimpilo yamehlo okwangoku kukukhusela ukukhanya okuluhlaza okwesibhakabhaka, kwaye iilensi ezisebenzayo ezineempawu zokukhanya okuchasene noluhlaza okwesibhakabhaka zithandwa kakhulu ngabathengi. Umonakalo we-UV uyinto exhalabisayo unyaka wonke kodwa ubonakala ngakumbi kwiinyanga zasehlotyeni ezishushu, ngoko ke imfuno yeelensi ze-photochromic ihlala ixesha elide.
Nangona iilensi ze-photochromic zifumaneka ngemibala eyahlukeneyo, iilensi ezingwevu zilungele kakhulu iisokisi. Ngaphandle, umbala ongwevu onzulu ngowona ukhululekileyo emehlweni; zihambelana kakuhle nayo nayiphi na ifreyimu yeglasi, nto leyo eyenza ukuba zibe lukhetho oluguquguqukayo kwimibala ye-photochromic.
Ngenxa yokukhethwa kweempawu ezininzi zokurhawuzelela, iilensi ze-photochromic ze-1.56 kunye ne-1.60 refractive index zithengiswa kakhulu evenkileni. Ukwandisa umlinganiselo wokuthengisa weelensi ze-photochromic ze-Safety Guard 1.60 clear-base anti-blue light akuncedi nje kuphela ukwandisa ixabiso eliphakathi loku-odola kodwa kukwaneengenelo ezicacileyo ezenza kube lula ukuthengiselana. Ukuze ufumane imigaqo-nkqubo engaphezulu yezinto ezikhoyo kunye nenkxaso emva kokuthengisa iilensi ze-photochromic ze-Safety Guard clear-base anti-blue light, nceda udibane nommeli wentengiso.
6. Imisebenzi yemibala eyahlukeneyoiilensi ze-photochromic?
