1.56 Ifoto eMabalabala ye-HMC iilensi ze-Optical
Iilensi zefotochromic, ezaziwa ngokuba "zii-photosensitive lens". Ngokomgaqo we-interconversion reversible reaction reversible, i-lens inokukhawuleza ibe mnyama phantsi kwe-radiation yokukhanya kunye nemitha ye-ultraviolet, ivimbe ukukhanya okunamandla kwaye ifake imitha ye-ultraviolet, kwaye ifunxe ukukhanya okubonakalayo ngokungathathi hlangothi; xa ibuyela kwindawo emnyama, inokubuyisela ngokukhawuleza imeko engenambala kunye ne-transparent, iqinisekisa i-lens yokudluliselwa. Ngoko ke, iilensi ze-photochromic zifanelekile zombini ukusetyenziswa kwangaphakathi nangaphandle ukukhusela umonakalo wamehlo ukusuka ekukhanyeni kwelanga, ukukhanya kwe-ultraviolet kunye ne-glare.

1.56 FSV Ifoto eGrey HMC iilensi zamehlo
Iilensi zePhotochromic azigcini nje ngokuchanekileyo ukubona, kodwa zikwaxhathisa uninzi lomonakalo wamehlo ovela kwimitha ye-UV. Izifo ezininzi zamehlo, ezifana nokuguga kwe-macular degeneration, i-pterygium, i-senile cataract kunye nezinye izifo zamehlo zihambelana ngokuthe ngqo kwimitha ye-ultraviolet, ngoko iilensi ze-photochromic zinokukhusela amehlo kwinqanaba elithile.
Iilensi zePhotochromic zinokuhlengahlengisa ukuhanjiswa kokukhanya ngokutshintsha kwelensi, ukuze iliso lomntu likwazi ukuziqhelanisa nokutshintsha kokukhanya okungqonge, ukunciphisa ukudinwa okubonakalayo nokukhusela amehlo.
