I. Umgaqo weeLensi zePhotochromic
Kwintlalo yanamhlanje, njengoko ungcoliseko lomoya lusiya lusiba mandundu kwaye umaleko we-ozone wonakala kancinci kancinci, iiglasi zamehlo zihlala zichatshazelwa lilanga elinobuninzi be-UV. Iilensi ze-photochromic ziqulathe ii-microcrystals zee-photochromic agents—i-silver halide kunye ne-copper oxide. Xa zichatshazelwa kukukhanya okunamandla, i-silver halide iyabola ibe yisilivere kunye ne-bromine; iikristale ezincinci zesilivere ezenziwe kule nkqubo zijika iilensi zibe mdaka mnyama. Xa ukukhanya kunyamalala, isilivere kunye ne-bromine ziphinda zihlangane zibe yi-silver halide phantsi kwesenzo se-catalytic se-copper oxide, zikhanyise iilensi kwakhona.
Xa iilensi ze-photochromic zivezwa kwimitha ye-ultraviolet (UV), ulwelo lwazo luba mnyama ngoko nangoko ngelixa luthintela ukungena kwe-UV, nto leyo ethintela kakhulu i-UVA kunye ne-UVB ekubeni zenzakalise amehlo. Kumazwe aphuhlileyo, iilensi ze-photochromic bezisoloko ziqatshelwa ngabathengi abaqaphela impilo ngenxa yeenzuzo zazo zempilo, ukulula kwazo, kunye nobuhle bazo. Ukukhula konyaka kwenani labathengi abakhetha iilensi ze-photochromic kufikelele kumanani aphindwe kabini.
II. Utshintsho lombala lweeLensi zePhotochromic
Ngeentsuku ezinelanga: Kusasa, umoya unesigqubuthelo samafu esincinci, esibangela ukuba i-UV ivalwe kancinci, nto leyo evumela ukuba imitha ye-UV engaphezulu ifikelele emhlabeni. Ngenxa yoko, iilensi ze-photochromic ziba mnyama kakhulu kusasa. Ngokuhlwa, amandla e-UV ayancipha—oku kungenxa yokuba ilanga likude nomhlaba, kwaye inkungu eqokelelene emini ithintela uninzi lwemitha ye-UV. Ke ngoko, umbala weelensi uba mhlophe kakhulu ngeli xesha.
Ngeentsuku ezinamafu: Imitha ye-UV isenokufikelela emhlabeni ngamandla amakhulu ngamanye amaxesha, ngoko ke iilensi ze-photochromic ziya kuba mnyama. Ngaphakathi, zihlala zibonakala phantse ngaphandle kombala okanye zingenambala. Ezi lensi zibonelela ngokhuseleko olufanelekileyo lwe-UV kunye nokukhanya kuyo nayiphi na indawo, zilungisa umbala wazo ngokukhawuleza ngokusekelwe kwiimeko zokukhanya. Ngelixa zikhusela ukubona, zibonelela ngokhuseleko lwempilo yamehlo kuyo yonke indawo nangaliphi na ixesha, naphi na.
Ubudlelwane nobushushu: Phantsi kweemeko ezifanayo, njengoko ubushushu bunyuka, umbala weelensi ze-photochromic ukhanya kancinci kancinci; ngokuchaseneyo, xa ubushushu buhla, iilensi ziba mnyama kancinci. Oku kuchaza isizathu sokuba umbala ukhanye ehlotyeni kwaye ube mnyama ebusika.
Isantya sokutshintsha kombala kunye nobunzulu bombala nazo zinxulumene nobukhulu belensi.
