Cov looj tsom iav dub yog ib yam khoom siv saib xyuas qhov muag kom tiv thaiv kev puas tsuaj rau tib neeg lub qhov muag los ntawm lub hnub ci zog.Nrog rau kev txhim kho ntawm tib neeg cov khoom siv thiab kev coj noj coj ua, looj tsom iav dub tuaj yeem siv los ua cov khoom siv tshwj xeeb rau kev zoo nkauj lossis tus kheej style.Peb lub qhov muag (lens) yog ib qho yooj yim heev rau nqus tau cov kab hluav taws xob ultraviolet, thiab kev puas tsuaj ntawm cov hluav taws xob ultraviolet rau lub qhov muag pom tsis pom.Txhawm rau tiv thaiv qhov muag, peb yuav tsum hnav looj tsom iav ib txwm.Ophthalmologists pom zoo tias koj yuav tsum tau hnav looj tsom iav ib txwm los tiv thaiv koj ob lub qhov muag;qhov no yog vim peb lub qhov muag (lens) yog ib qho yooj yim heev kom nqus tau cov kab hluav taws xob ultraviolet, thiab kev puas tsuaj ntawm cov kab hluav taws xob ultraviolet muaj ob yam tseem ceeb: 1. Kev puas tsuaj ntawm cov hluav taws xob ultraviolet yuav sib sau.Txij li thaum lub teeb ultraviolet yog qhov pom tsis pom, nws nyuaj rau tib neeg kom pom nws intuitively.2. Kev puas tsuaj ntawm cov hluav taws xob ultraviolet rau lub qhov muag yog irreversible, uas yog, irreparable.Xws li: phais kab mob cataract tsuas yog hloov los ntawm cov lo ntsiab muag intraocular.Kev puas tsuaj rau lub qhov muag ntev tuaj yeem yooj yim ua rau lub cornea thiab retina puas, clouding ntawm lub lens kom txog thaum cataract tshwm sim, ua rau pom kev puas tsuaj mus tas li.
Qhov tsis meej ntawm cov iav hloov xim yog nyob rau hauv iav.Cov iav tshwj xeeb no hu ua "photochromic" iav.Nyob rau hauv cov txheej txheem tsim, nws yog pre-doped nrog lub teeb-rhiab tshuaj, xws li nyiaj chloride, nyiaj bromide (collectively hu ua silver halide), thiab lwm yam, raws li zoo raws li ib tug me me ntawm tooj liab oxide catalyst.Lub spectacle lo ntsiab muag hloov los ntawm tsis muaj xim mus rau lub teeb grey thiab tsaus xim av, thiab tom qab ntawd los ntawm cov tsom iav dub mus rau lub suab nrov tsom iav, tag nrho cov uas yog khawv koob ntawm nyiaj halide.Nyob rau hauv lub iav ntawm cov xim-hloov tsom iav, muaj kev hloov pauv zoo ib yam li cov duab pom ntawm cov duab photosensitive.Txheej txheem.Silver halide yog decomposed los ntawm lub teeb thiab dhau los ua ntau cov nyiaj dub, uas tau muab sib npaug hauv cov iav, yog li lub iav lo ntsiab muag zoo li dim thiab thaiv qhov kev pom ntawm lub teeb, uas yog tsom iav dub.Txawm li cas los xij, nws txawv ntawm qhov xwm txheej ntawm cov yeeb yaj kiab photosensitive., cov nyiaj atoms thiab halogen atoms generated los ntawm decomposition ntawm silver halide tseem nyob ze ua ke.Thaum rov qab mus rau qhov chaw tsaus me ntsis, raws li kev txhawb nqa ntawm tooj liab oxide catalyst, nyiaj thiab halogen recombine los ua nyiaj halide, iav lo ntsiab muag tau pob tshab dua.
Ntau lub tuam txhab looj tsom iav dub siv cov txheej txheem hu ua qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.Qhov no yog cov txheej txheem tsim khoom qub tshaj plaws rau cov looj tsom iav dub, thiab tag nrho cov iav los yog cov khoom siv polycarbonate muaj tib xim.Yog li ntawd, nyob rau hauv tus txheej txheem ntawm kev tsim lub lens, cov xim yog nyob rau hauv lub lens.Txheej txheej ntawm lub teeb-absorbing molecules nyob rau saum npoo ntawm ntshiab polycarbonate kuj yog ib txoj kev dyeing.Txoj hauv kev zoo tshaj plaws rau tint polycarbonate lo ntsiab muag yog tsau rau hauv cov kua tshwj xeeb uas muaj cov tshuaj tinting uas yuav maj mam nqus rau hauv cov yas.Rau cov xim tsaus, tsuas yog ncua sij hawm lub lens rau hauv cov kua.
