Ilensi ye-Photochromic, eyaziwa ngokuba yilensi yokukhanya, yenziwe ngokwethiyori yokusabela okuguquguqukayo kokukhanya kunye nokutshintshana kombala. Ilensi ye-Photochromic inokuba mnyama ngokukhawuleza phantsi kwelanga okanye ukukhanya kwe-ultraviolet. Ingavimba ukukhanya okunamandla kwaye ifunxe ukukhanya kwe-ultraviolet, kunye nokufunxa ukukhanya okubonakalayo ngokungakhethiyo. Ibuyele ebumnyameni, inokubuyisela ngokukhawuleza imeko ecacileyo necacileyo, iqinisekise ukuhanjiswa kokukhanya kwelensi. Ke ngoko, iilensi ze-photochromic zifanelekile ukusetyenziswa ngaphakathi nangaphandle ngaxeshanye ukuthintela umonakalo emehlweni ngenxa yelanga, ukukhanya kwe-ultraviolet, kunye nokukhanya okukhanyayo.
Ngokubanzi, imibala ephambili yeelensi ze-photochromic ingwevu kwaye imdaka.
Ingwevu yePhotochromic:
Ingafunxa ukukhanya kwe-infrared kunye ne-98% yokukhanya kwe-ultraviolet. Xa ujonga izinto ngeelensi ezingwevu, umbala wezinto awuyi kutshintshwa, kodwa umbala uya kuba mnyama, kwaye ukukhanya kuya kuncipha ngokufanelekileyo.
Umdaka onombala we-Photochromic:
Ingafunxa i-100% yemitha ye-ultraviolet, ihluze ukukhanya okuluhlaza okwesibhakabhaka, iphucule umahluko nokucaca okubonakalayo, kunye nokukhanya okubonakalayo. Ifanelekile ukunxitywa xa kungcoliseka kakhulu emoyeni okanye kwiimeko ezinenkungu, kwaye lukhetho olufanelekileyo kubaqhubi.
Indlela yokugweba iilensi ze-photochromic ukuba zilungile okanye zimbi?
1. Isantya sokutshintsha umbala: Iilensi ezilungileyo ezitshintsha umbala zinesantya sokutshintsha umbala ngokukhawuleza, kungakhathaliseki ukuba zicacile okanye zimnyama, okanye zimnyama okanye zicacile.
2. Ubunzulu bombala: okukhona imisebe ye-ultraviolet yelensi elungileyo ye-photochromic iqina, kokukhona umbala uya kuba mnyama. Iilensi eziqhelekileyo ze-photochromic zisenokungakwazi ukufikelela kumbala onzulu.
3. Iilensi ezimbini ze-photochromic ezinombala ofanayo wesiseko kunye nesantya kunye nobunzulu bokutshintsha kombala.
4. Ukunyamezelana kokutshintsha kombala kakuhle kunye nobude bexesha.
Iintlobo zeelensi ze-photochromic:
Ngokwendlela yokuvelisa, kukho iintlobo ezimbini zeelensi ze-photochromic: Ngokwezinto eziphathekayo, nangokugquma (ukugquma nge-spin coating/dipping coating).
Kule mihla, ilensi ye-photochromic ethandwayo ngokwezinto ezibonakalayo ikakhulu yi-1.56 index, ngelixa iilensi ze-photochromic ezenziwe ngokugquma zinokukhetha okungakumbi, njenge-1.499/1.56/1.61/1.67/1.74/PC.
Umsebenzi wokusika okuluhlaza okwesibhakabhaka udityaniswe kwiilensi ze-photochromic ukubonelela ngokhuseleko olungakumbi lwamehlo.
Amanyathelo okuphepha xa uthenga iilensi ze-photochromic:
1. Ukuba umahluko we-diopter phakathi kwamehlo amabini ungaphezulu kwe-100 degrees, kuyacetyiswa ukuba ukhethe iilensi ze-photochromic ezenziwe nge-coating, ezingayi kubangela imibala eyahlukeneyo yokutshintsha kombala welensi ngenxa yobukhulu obahlukeneyo beelensi ezimbini.
2. Ukuba iilensi ze-photochromic zinxitywe ixesha elingaphezu konyaka, kwaye enye yazo yonakele kwaye kufuneka itshintshwe, kuyacetyiswa ukuba zitshintshwe zombini kunye, ukuze isiphumo sokutshintsha kombala weelensi ezimbini singabi sahluka ngenxa yexesha lokusetyenziswa kweelensi ezimbini ezahlukeneyo.
3. Ukuba unexinzelelo oluphezulu lwangaphakathi kwamehlo okanye iglaucoma, musa ukunxiba iilensi ze-photochromic okanye iiglasi zelanga.

Iilensi ze-photochromic zihlala ixesha elingakanani?
Kwimeko yokugcinwa kakuhle, ukusebenza kweelensi ze-photochromic kunokugcinwa iminyaka emi-2 ukuya kwemi-3. Ezinye iilensi eziqhelekileyo nazo ziya kunyibilika zize zijike zibe tyheli emva kokusetyenziswa imihla ngemihla.
Ngaba iya kutshintsha umbala emva kwexesha elithile?
Ukuba ilensi inxitywa ixesha elithile, ukuba umaleko wefilimu uyawa okanye ilensi inxityiwe, oko kuya kuchaphazela ukusebenza kombala wefilimu ye-photochromic, kwaye umbala usenokungalingani; ukuba umbala unzulu ixesha elide, umphumo wombala uya kuchaphazela, kwaye kunokubakho ukungaphumeleli kombala okanye ukuba kwimeko emnyama ixesha elide. Sibiza loo lensi ye-photochromic ngokuthi "ifile".
Ngaba iya kutshintsha umbala ngeentsuku ezinamafu?
Kukwakho nemisebe ye-ultraviolet kwiintsuku ezinamafu, eya kuvuselela i-discolor factor kwilensi ukuze yenze imisebenzi. Okukhona imisebe ye-ultraviolet inamandla, kokukhona i-discolor isiba nzulu; okukhona iqondo lobushushu liphezulu, kokukhona i-discolor isiba mhlophe. Ubushushu buphantsi ebusika, ilensi iyaphela kancinci kwaye umbala unzulu.
