1.56 I-Semi Finished Blue Cut Bifocal Ifoto engwevu iilensi zamehlo
Ngaphantsi kokukhanya kwelanga, umbala we-lens uba mnyama kwaye ukuhanjiswa kokukhanya kuncipha xa kukhanyiselwa yi-ultraviolet kunye ne-short-wave ebonakalayo. Kwilensi yangaphakathi okanye emnyama ukuhanjiswa kokukhanya kuyanda, buyela ekukhanyeni. I-photochromism yeelensi iyazenzekela kwaye ibuyiselwa umva. Iiglasi eziguqula umbala ziyakwazi ukulungelelanisa ukuhanjiswa ngokutshintshwa kombala we-lens, ukwenzela ukuba iliso lomntu likwazi ukulungelelanisa utshintsho lokukhanya kwendalo, ukunciphisa ukukhathala okubonakalayo, nokukhusela amehlo.

Ngokuqhelekileyo, iiglasi ze-myopia eziguqula umbala azikwazi nje ukuzisa lula kunye nobuhle kodwa ziyakwazi ukumelana ngokufanelekileyo ne-ultraviolet kunye ne-glare, zinokukhusela amehlo, isizathu sokutshintsha kombala kukuba xa i-lens yenziwe, ixutywe kunye nezinto ezilula ukukhanya. , njengesilivere ye-chloride, i-silver halide (eyaziwa ngokuba yi-silver halide), kunye nexabiso elincinci le-copper oxide catalyst. Nanini na xa i-halide yesilivere ikhanyiswa kukukhanya okunamandla, ukukhanya kuya kubola kwaye kube ngamasuntswana amaninzi esilivere amnyama asasazwe ngokulinganayo kwilensi. Ngoko ke, i-lens iya kubonakala imnyama kwaye ivimbele ukuhamba kokukhanya. Ngeli xesha, i-lens iya kuba nemibala, enokuthi ithintele ukukhanya ukufezekisa injongo yokukhusela amehlo.
