Ilensi ye-Photochromic yilensi etshintsha umbala ngokutshintsha kokukhanya kwangaphandle. Inokuba mnyama ngokukhawuleza xa ilanga likhanya, kwaye ukuhanjiswa kwayo kuyehla kakhulu. Okukhona ukukhanya kunamandla, kokukhona umbala welensi umnyama, kwaye ngokuchaseneyo. Xa ilensi ibuyiselwa ngaphakathi, umbala welensi unokukhawuleza ubuye kwimeko yawo yokuqala ecacileyo.
Utshintsho lombala lujoliswa kakhulu kukutshintsha kombala ngaphakathi kwilensi. Yindlela yokusabela eguqukayo ngokwekhemikhali.
Ngokubanzi, kukho iintlobo ezintathu zobuchwepheshe bokuvelisa ilensi ye-photochromic: i-in-mass, i-spin coating, kunye ne-dip coating.
Iilensi ezenziwe ngendlela yokuvelisa ngobuninzi zinembali ende nezinzileyo yemveliso. Okwangoku, zenziwe nge-1.56 index, zifumaneka nge-single vision, bifocal kunye ne-multi-focal.
I-Spin coating yinguqu enkulu kwimveliso yelensi ye-photochromic, ukufumaneka kweelensi ezahlukeneyo ukusuka kwi-1.499 ukuya kwi-1.74. I-Spin coating i-photochromic inombala okhanyayo, isantya esikhawulezayo, kwaye inombala omnyama kwaye ulingana emva kokutshintsha.
I-dip coating kukufaka ilensi kulwelo lwezinto ze-photochromic, ukuze igqume ilensi ngomaleko we-photochromic kumacala omabini.
I-Universe Optical izinikele ekufuneni ilensi ye-photochromic egqwesileyo. Ngenxa yesixhobo esinamandla sophando nophuhliso, kubekho uthotho lweelensi ze-photochromic ezisebenza kakuhle kakhulu. Ukusuka kwi-photochromic yendabuko eyi-1.56 enobunzima obutshintsha umbala omnye, ngoku siphuhlise ezinye iilensi ezintsha ze-photochromic, ezifana neelensi ze-blueblock photochromic kunye neelensi ze-photochromic ezigubungelayo.
