I. Molao-motheo oa Lilense tsa Photochromic
Sechabeng sa mehleng ena, ha tšilafalo ea moea e ntse e mpefala 'me lera la ozone le senyeha butle-butle, likhalase tsa mahlo hangata li pepesetsoa khanya ea letsatsi e nang le UV e ngata. Lilense tsa Photochromic li na le likristale tse nyane tsa li-photochromic agents - halide ea silevera le oxide ea koporo. Ha li pepesetsoa khanya e matla, halide ea silevera e bola ho ba silevera le bromine; likristale tse nyane tsa silevera tse entsoeng ts'ebetsong ena li fetola lilense hore li be sootho bo lefifi. Ha khanya e fela, silevera le bromine li kopana hape ho ba halide ea silevera tlas'a ketso ea catalytic ea oxide ea koporo, e leng se etsang hore lilense li bonesoe hape.
Ha lilense tsa photochromic li pepesetsoa mahlaseli a ultraviolet (UV), lesira la tsona le fifala hang-hang ha le ntse le thibela ho kenella ha UV, e leng se thibelang haholo UVA le UVB ho senya mahlo. Linaheng tse tsoetseng pele, lilense tsa photochromic li 'nile tsa tsejoa ke bareki ba hlokomelang bophelo bo botle ka melemo ea tsona ea bophelo bo botle, boiketlo le botle. Keketseho ea selemo le selemo palong ea bareki ba khethang lilense tsa photochromic e fihlile lipalo tse habeli.
II. Liphetoho tsa 'Mala tsa Lilense tsa Photochromic
Matsatsing a letsatsi: Hoseng, moea o na le leru le lesesaane, le fanang ka thibelo e fokolang ea UV, e leng se lumellang mahlaseli a mangata a UV ho fihla fatše. Ka lebaka leo, lilense tsa photochromic li fifala haholo hoseng. Mantsiboea, matla a UV aa fokola—sena se bakoa ke hore letsatsi le hole le mobu, 'me moholi o bokellanang motšehare o thibela mahlaseli a mangata a UV. Ka hona, 'mala oa lilense o ba bobebe haholo nakong ena.
Matsatsing a maru: Mahlasedi a UV a ntse a ka fihla fatše ka matla a maholo ka linako tse ling, kahoo lilense tsa photochromic li ntse li fifala. Ka tlung, li lula li bonaletsa hoo e ka bang ntle le 'mala o mobe kapa li se na 'mala. Lilense tsena li fana ka tšireletso e ntle ka ho fetisisa ea UV le khanya tikolohong efe kapa efe, li fetola 'mala oa tsona kapele ho latela maemo a leseli. Leha li sireletsa pono, li fana ka tšireletso ea bophelo bo botle ba mahlo neng kapa neng, kae kapa kae.
Kamano le mocheso: Tlas'a maemo a tšoanang, ha mocheso o ntse o phahama, 'mala oa lilense tsa photochromic o khanya butle-butle; ka lehlakoreng le leng, ha mocheso o theoha, lilense li fifala butle-butle. Sena se hlalosa hore na ke hobane'ng ha 'mala o le bobebe lehlabula 'me o le lefifi mariha.
Lebelo la phetoho ea 'mala le botebo ba 'mala le tsona li na le kamano e itseng le botenya ba lense.
