I-PhotoChromic Lens iyi-lens eshintsha umbala oshintsha ngokushintshwa kokukhanya kwangaphandle. Kungaphenduka ubumnyama masinyane ngaphansi kwelanga, futhi ukudluliselwa kwalo kwehla kakhulu. Ukukhanya okunamandla, okumnyama umbala welensi, kanye okuphambene nalokho. Lapho ilensi ibuyiselwanga ngaphakathi endlini, umbala welensi ungaphela ngokushesha ubuyela emuva kombuso wokuqala osobala.
Ukushintshwa kombala kuthambekele ikakhulukazi yisici sokudilizwa ngaphakathi kwelensi. Ukusabela kwamakhemikhali okubuyela emuva.

Ngokuvamile, kunezinhlobo ezintathu ze-PhotoChromic Lens Production Technology: in-mass, spin coating, bese ucwilisa ama-coating.
Ilensi eyenziwe yindlela yokukhiqizwa ngobuningi inomlando omude futhi ozinzile. Njengamanje, kwenziwa ikakhulukazi nge-1.56 inkomba, etholakala ngombono owodwa, i-bifocal kanye nokugxila okuhlukahlukene.
I-Spin Coating yinguquko ekukhiqizweni kwe-lens ye-photochromic, ukutholakala kwamalensi ahlukene kusuka ku-1.499 kuye ku-1.74. I-Spin Coating Photing Photochromic inombala olula wesisekelo, isivinini esisheshayo, kanye nobumnyama ngisho nombala ngemuva koshintsho.
I-DIP Coating ukucwilisa i-lens ku-PhotoChromic wezinto ezibonakalayo, ukuze uhlanganise ilensi nge-Photochromic ungqimba ezinhlangothini zombili.

I-Univel Optical inikezelwe ekuphishekeleni ilensi enhle ye-photochromic. Ngendawo eqinile ye-R & D, kube nochungechunge oluningi lwama-PhotoChromic lens ngokusebenza okuhle. Kusuka ku-PhotoChromic yendabuko 1.56 PhotoChromic ngomsebenzi oguqukayo wombala owodwa, manje sesithuthukise amalensi amasha we-photochromic, njenge-Blueblock Photochromic lens kanye namalensi we-spin coating PhotoChromic.
