1.67 Spin Photochromic Grey HMC iilensi zamehlo
Iilensi ezitshintsha umbala, ezaziwa ngokuba zii "photosensitive lens". Ngokomgaqo we-photochromatic tautometry reversible reaction, ilens inokuba mnyama ngokukhawuleza phantsi kokukhanya kunye ne-ultraviolet irradiation, ithintele ukukhanya okuqinileyo kwaye ifunxe ukukhanya kwe-ultraviolet, kwaye ibonise ukungathathi hlangothi kokukhanya okubonakalayo. Ukubuyela ebumnyameni, kunokubuyisela ngokukhawuleza imeko ecacileyo engenambala, qinisekisa ukuhanjiswa kwelensi. Ngoko ke, iilensi eziguqula umbala zifanelekile ukusetyenziswa kwangaphakathi nangaphandle ngexesha elifanayo ukukhusela umonakalo wokukhanya kwelanga, ukukhanya kwe-ultraviolet kunye ne-glare emehlweni.
