I-Photochromic lens iyilensi eshintsha umbala ngokushintsha kokukhanya kwangaphandle. Ingajika ibe mnyama ngokushesha ngaphansi kokukhanya kwelanga, futhi ukudluliselwa kwayo kwehla kakhulu. Ukukhanya kunamandla, umbala welensi uba mnyama, futhi okuphambene nalokho. Uma ilensi ibuyiselwa endlini, umbala welensi ungafiphala ngokushesha ubuyele esimweni sokuqala sokukhanyela.
Ukushintsha kombala kuqondiswe kakhulu yisici sokushintsha umbala ngaphakathi kwelensi. Ukusabela okubuyiseleka emuva kwamakhemikhali.
Ngokuvamile, kunezinhlobo ezintathu zobuchwepheshe bokukhiqiza ilensi ye-photochromic: in-mass, i-spin coating, ne-dip coating.
Ilensi eyenziwe ngendlela yokukhiqiza ngobuningi inomlando omude futhi ozinzile wokukhiqiza. Njengamanje, yenziwe ngokuyinhloko ngenkomba engu-1.56, etholakala ngombono owodwa, i-bifocal kanye ne-multi-focal.
I-Spin coating iwuguquko ekukhiqizweni kwamalensi e-photochromic, ukutholakala kwamalensi ahlukene ukusuka ku-1.499 kuya ku-1.74. I-spin coating photochromic inombala wesisekelo okhanyayo, isivinini esisheshayo, kanye nobumnyama ngisho nombala ngemva koshintsho.
I-Dip coating iwukucwilisa ilensi oketshezini lwe-photochromic, ukuze imboze ilensi ngongqimba lwe-photochromic nhlangothi zombili.
I-Universe Optical inikezelwe ekuphishekeleni amalensi e-photochromic amahle kakhulu. Ngesikhungo esiqinile se-R&D, kube nochungechunge oluningana lwamalensi e-photochromic asebenza kahle kakhulu. Kusukela ku-1.56 ye-photochromic evamile esebenza ngokushintsha umbala owodwa, manje sesenze amalensi amasha e-photochromic, njengamalensi e-photochromic e-blueblock kanye namalensi e-spin coating photochromic.
