Kuluntu lwanamhlanje, ukungcola komoya kuya kuba nzima ngakumbi, i-ozone layer yonakaliswa kancinci, kwaye iiglasi zibonakaliswe kwimisebe ye-ultraviolet yelanga.Amaphepha ePhotochromic ziinkozo ezincinci zesilivere zehalide kunye necopper oxide kwilensi equlethe izinto ezitshintsha umbala.Xa i-radiated kukukhanya okunamandla, i-silver halide ibola ibe yisilivere kunye ne-bromine, kunye neenkozo ezincinci zesilivere ezibolileyo zenza i-lens ibonakale imnyama;xa ukukhanya kuba mnyama, isilivere kunye ne-halide ivuselela i-halide yesilivere phantsi kwe-catalysis ye-oxide yobhedu., ngoko umbala welensi uba lula kwakhona.
Okwesibini, utshintsho lombala wefilimu eguqula umbala
1. Xa ilanga: kusasa, amafu omoya ancinci, imisebe ye-ultraviolet ayivalwanga kangako, kwaye ifikelela ngakumbi emhlabeni, ngoko ke ubunzulu beelensi eziguqula umbala ekuseni nazo zinzulu.Ngokuhlwa, imisebe ye-ultraviolet iyancipha, kuba ilanga lide kude nomhlaba kusihlwa, kwaye ininzi yemitha ye-ultraviolet ivalwe ngokuqokelelwa kwenkungu emini;ngoko ubunzulu bokutshintsha kwebala bunzulu kakhulu ngeli xesha.
2. Xa kunamafu: imitha ye-ultraviolet ngamanye amaxesha ayinabuthakathaka kwaye inokufikelela emhlabeni, ngoko iilensi eziguqula umbala zisenokutshintsha umbala.Phantse akukho mbala kunye nokubonakala kakhulu ngaphakathi, iilensi ezitshintsha umbala zinokubonelela ngezona glasi zifanelekileyo kwi-UV kunye nokhuseleko lwe-glare kuyo nayiphi na indawo, ukulungelelanisa umbala weelensi ngexesha ngokuhambelana nokukhanya, kwaye unikeze ukhuseleko lwezempilo lwamehlo nanini na, naphi na ngelixa ukhusela umbono.
3. Ubudlelwane phakathi kweelensi ezitshintsha umbala kunye nobushushu: Ngaphantsi kweemeko ezifanayo, njengoko izinga lokushisa linyuka, umbala weelensi zokutshintsha umbala uya kuba lula ngakumbi njengoko ubushushu bukhula;ngokuchaseneyo, xa iqondo lokushisa liyancipha, iilensi zokutshintsha umbala ziya kuncipha.Kancinci ungene nzulu.Yiyo loo nto kukhanya ehlotyeni kwaye kube mnyama ebusika.
4. Isantya sokutshintsha kombala, ubunzulu bukwanxulumene nobukhulu be-lens
