Emphakathini wanamuhla, ukungcoliswa komoya kuya kuba kubi nakakhulu, ungqimba lwe-ozone lonakaliswa kancane, futhi izibuko zivezwe emisebeni yelanga ye-ultraviolet.Amashidi e-Photochromic ayizinhlamvu ezincane ze-silver halide ne-copper oxide kulens equkethe izici ezishintsha umbala.Lapho ikhanyiswe ukukhanya okunamandla, i-halide eyisiliva iyabola ibe isiliva ne-bromine, futhi izinhlamvu ezincane zesiliva ezibolile zenza ilensi ibonakale insundu ngokumnyama;lapho ukukhanya kuba mnyama, isiliva ne-halide zivuselela i-halide yesiliva ngaphansi kwe-catalysis ye-copper oxide., ngakho umbala welensi uba lula futhi.
Okwesibili, ukushintsha kombala wefilimu eshintsha umbala
1. Uma libalele: ekuseni, amafu omoya mancane, imisebe ye-ultraviolet ivalekile kancane, futhi ifinyelela ngaphezulu emhlabathini, ngakho ukujula kwama-lens ashintsha umbala ekuseni nakho kujulile.Kusihlwa, imisebe ye-ultraviolet ibuthakathaka kakhulu, ngoba ilanga likude nomhlabathi kusihlwa, futhi imisebe eminingi ye-ultraviolet ivinjelwe ukuqoqwa kwenkungu emini;ngakho ukujula kokuguquka kombala akujulile kakhulu ngalesi sikhathi.
2. Uma kuguqubele: imisebe ye-ultraviolet ngezinye izikhathi ayibuthakathaka futhi ingafika phansi, ngakho amalensi ashintsha umbala asengashintsha umbala.Cishe akukho ukushintsha kombala futhi okusobala kakhulu endlini, amalensi ashintsha umbala anganikeza izibuko ezifanele kakhulu zokuvikela i-UV kanye ne-glare kunoma iyiphi indawo, alungise umbala wamalensi ngesikhathi ngokuvumelana nokukhanya, futhi anikeze isivikelo sezempilo samehlo nganoma yisiphi isikhathi, noma yikuphi ngenkathi ivikela umbono.
3. Ubudlelwano phakathi kwamalensi ashintsha umbala kanye nezinga lokushisa: Ngaphansi kwezimo ezifanayo, njengoba izinga lokushisa likhuphuka, umbala wamalensi ashintsha umbala uyoba lula kancane kancane njengoba izinga lokushisa likhula;ngokuphambene nalokho, lapho izinga lokushisa liyancipha, ama-lens ashintsha umbala azonciphisa.Kancane kancane ngena ujule.Yingakho kukhanya ehlobo bese kuba mnyama ebusika.
4. Ijubane lokushintsha kombala, ukujula nakho kuhlobene nobukhulu be-lens
