I-Photochromicilensi, yiilensi yeglasi yeliso ebonakala lula ekhanya kakhulu ejika ibe mnyama ngokuzenzekelayo xa ilanga likhanya kwaye ikhanye xa kukhanyisiwe kancinci.
Ukuba ucinga ngeelensi ze-photochromic, ingakumbi ukulungiselela ixesha lasehlotyeni, nazi izinto ezininzi ezinokukunceda uzazi ngeelensi ze-photochromic, zisebenza njani, indlela ozuza ngayo kuzo kunye nendlela yokufumana ezona zilungele wena.
Indlela iilensi ze-photochromic ezisebenza ngayo
Iimolekyuli ezibangela ukuba iilensi ze-photochromic zibe mnyama zivuselelwa yimitha yelanga ye-ultraviolet. Nje ukuba zivele, iimolekyuli ezikwiilensi ze-photochromic zitshintsha ulwakhiwo kwaye zihambe, zisebenza ukuze zibe mnyama, zifunxe ukukhanya kwaye zikhusele amehlo akho kwimitha yelanga eyonakalisayo.
Ngaphandle kwe-monomer photochromic, itekhnoloji entsha yokwenza iiglasi ze-spin ivumela ukuba iilensi zeglasi ze-photochromic zifumaneke phantse kuzo zonke izixhobo kunye noyilo lweelensi, kubandakanya iilensi ezine-index ephezulu, iilensi ze-bifocal kunye neelensi eziqhubekekayo.
Olu qweqwe lwe-photochromic lwenziwe ziitriliyoni zeemolekyuli ezincinci ze-silver halide kunye ne-chloride, ezisabela kwimitha ye-ultraviolet (UV) elangeni.
Iingenelo zeelensi ze-photochromic
Ngenxa yokuba ubomi bomntu buphela xa echatshazelwa lilanga kunye nemitha ye-UV kuye kwanxulunyaniswa ne-cataracts kamva ebomini, licebo elihle ukuqwalasela iilensi ze-photochromic kwiiglasi zamehlo zabantwana kunye neeglasi zamehlo zabantu abadala.
Nangona iilensi ze-photochromic zibiza ngaphezulu kuneelensi zeglasi ezicacileyo, zibonelela ngokulula kokunciphisa isidingo sokuhamba neeglasi zelanga ezibhalwe ngugqirha naphi na apho uya khona.
Enye inzuzo yeelensi ze-photochromic kukuba zikhusela amehlo akho kwi-100% yemitha yelanga eyingozi ye-UVA kunye ne-UVB.
Zeziphi iilensi ze-photochromic ezifanelekileyo kuwe?
Iinkampani ezininzi zibonelela ngeelensi ze-photochromic zeglasi. Ungayifumana njani eyona ifanelekileyo kwiimfuno zakho? Qala ngokucinga ngemisebenzi yakho yemihla ngemihla kunye nendlela ophila ngayo.
Ukuba uthanda ukuphuma ngaphandle, ungacinga ngeeglasi ze-photochromic ezineefreyimu ezihlala ixesha elide kunye nezixhobo zelensi ezimelana nokuchaphazeleka ezifana ne-polycarbonate okanye i-Ultravex, ezizezona zixhobo zelensi zikhuselekileyo ebantwaneni, ezibonelela ngokuxhathisa ukuchaphazeleka okuphindwe kalishumi kunezinye izinto zelensi.
Ukuba uxhalabile kakhulu ngokuba nokhuseleko olongezelelekileyo njengoko kufuneka usebenze kwikhompyutha imini yonke, ungacinga ngelensi ye-photochromic kunye nomsebenzi wesihluzi sokukhanya okuluhlaza okwesibhakabhaka. Kwanelensi ayizukuba mnyama ngaphakathi, usenokufumana ukhuseleko olungcono kwizibane eziluhlaza okwesibhakabhaka ezinamandla aphezulu xa ujonge isikrini.
Xa kufuneka uqhube kusasa okanye uhambe kwimozulu embi, ungacinga nge-Brown photochromic lens. Kungenxa yokuba ihluza yonke eminye imibala kakuhle ukuze ukwazi ukubona ngokucacileyo kwaye ufumane icala elifanelekileyo.
