Ihlobo lizisa iintsuku ezinde kunye nokukhanya kwelanga okunamandla.Namhlanje, uya kubona abantu abaninzi
ukunxiba iilensi photochromic, ezilungisa i-tint yazo ngokusekwe ekutyhilekeni kokukhanya.
Ezi lens zithandwa kakhulu kwimarike yamehlo, ngakumbi ehlotyeni,enkosi kubuchule babo
ukutshintsha umbala nokukhusela kwimitha yelanga. Baninzi abantu abaqaphelayo
Umonakalo wemitha ye-UV unokubangela, kungekuphela nje eluswini kodwa nasemehlweni ethu.
Ngelixa Umonakalo we-UVemehlweni asenokungakhawulezi njengokutshiswa lilanga, ukuba sesichengeni ixesha elide kunokukhokelela kwimiba yamehlo enzulu, efana norhatyazo kunye nokonakala kwe-macular.
ETshayina,kusekho ukunqongophala kwemvumelwano malunga nexesha lokunxibaiindondo zelanga.Nangona ukukhanya kwangaphandle okunamandla, abaninzi bakhetha ukunganxibieyewear ekhuselayo.
Iilensi zePhotochromic,umbono ochanekileyo kunye nokukhusela ekukhanyeni ngaphandle kokufuna ukutshintsha iiglasi, kuya kuba lukhetho olukhethiweyo.
Iilensi zefotokhromic ziba mnyama ekukhanyeni okuqaqambileyo (njengangaphandle) kwaye zicace ngaphakathi. Olu tshintsho lubangelwa yinto ebizwa ngokuba yi-silver halide kwiilensi.
esabela ekukhanyeni, itshintsha umbala welensi ngokusekelwe kukukhanya kunye nobushushu. Ke, iilensi ziba mnyama phantsi kokukhanya kwelanga kwaye zikhanyise
ekukhanyeni okusezantsi okanye kubushushu obupholileyo.
Nantsi ukujonga ngokukhawuleza kwimibuzo eqhelekileyo malungaiilensi photochromic:
