1.56 Semi Finished Diam duab grey Optical Lenses
Lub iav lens ntawm lub lens hloov xim muaj qee qhov nyiaj chloride, sensitizer thiab tooj liab. Nyob rau hauv cov xwm txheej ntawm lub teeb yoj luv, nws tuaj yeem decomposed rau hauv cov nyiaj atoms thiab chlorine atoms. Chlorine atoms tsis muaj xim thiab nyiaj atoms yog xim. Qhov concentration ntawm cov nyiaj atoms tuaj yeem tsim ib lub xeev colloidal, uas yog qhov peb pom zoo li lub lens discoloration. Lub hnub ci zog dua, cov nyiaj atoms sib cais ntau dua, lub lens yuav tsaus dua. Qhov qis dua lub hnub ci, cov nyiaj atoms tsawg dua tau sib cais, lub teeb lub lens yuav yog. Tsis muaj hnub ci ncaj qha hauv chav, yog li cov lo ntsiab muag ua tsis muaj xim.

1.56 Semi Finished Blue Hlais Porgressive optical lo ntsiab muag
Multifocal tsom iav muaj cov kab luv luv thiab cov kab ntev. Kev xaiv ntawm channel yog qhov tseem ceeb. Feem ntau, peb thawj zaug xav txog kev xaiv cov channel luv luv, vim tias cov channel luv luv yuav muaj kev pom loj dua, uas yog raws li kev ua neej ntawm cov neeg uas feem ntau saib lawv lub xov tooj ntawm tes. Qhov sib txawv ntawm ob lub qhov muag yog qhov loj, lub qhov muag ntawm qhov muaj peev xwm tig qis ntawm cov neeg, kuj yog qhov tsim nyog rau cov kab luv luv. Yog tias tus neeg siv khoom tau hnav ntau lub ntsej muag rau thawj zaug, muaj qhov xav tau nruab nrab ntawm qhov nruab nrab, thiab qhov Ntxiv yog qhov siab, ces qhov ntev channel tuaj yeem txiav txim siab.

1.56 Semi Tiav Xiav Hlais Bifocal Yees Duab Grey optical lo ntsiab muag
Nyob rau hauv tshav ntuj, cov xim ntawm lub lens yuav tsaus dua thiab lub teeb xa hluav taws xob txo qis thaum nws yog irradiated los ntawm ultraviolet thiab luv-yoj pom lub teeb. Nyob rau hauv tsev los yog tsaus lens lub teeb transmittance nce, ploj rov qab mus rau qhov kaj. Lub photochromism ntawm lo ntsiab muag yog tsis siv neeg thiab thim rov qab. Cov iav hloov xim tuaj yeem kho qhov kev xa tawm los ntawm kev hloov xim ntawm lub lens, kom tib neeg lub qhov muag tuaj yeem hloov pauv ntawm ib puag ncig lub teeb, txo qhov pom kev qaug zog, thiab tiv thaiv lub qhov muag.

1.56 Semi Finished Bifocal Diam duab grey optical lo ntsiab muag
Feem ntau, cov xim hloov cov iav tsom iav tuaj yeem tsis tsuas yog ua kom yooj yim thiab kev zoo nkauj tab sis kuj tuaj yeem tiv thaiv ultraviolet thiab glare, tuaj yeem tiv thaiv ob lub qhov muag, vim li cas cov xim hloov xim yog thaum lub lens tsim, nws yog tov nrog cov khoom siv lub teeb. , xws li nyiaj chloride, nyiaj halide (collectively hu ua silver halide), thiab ib tug me me ntawm tooj liab oxide catalyst. Thaum twg cov nyiaj halide illuminated los ntawm lub teeb muaj zog, lub teeb yuav decompose thiab dhau los ua ntau cov nyiaj dub sib npaug sib npaug hauv lub lens. Yog li ntawd, lub lens yuav tshwm sim dim thiab thaiv txoj kev ntawm lub teeb. Lub sijhawm no, lub lens yuav dhau los ua xim, uas tuaj yeem tiv thaiv lub teeb kom ua tiav lub hom phiaj ntawm kev tiv thaiv lub qhov muag.

Xim-hloov lo ntsiab muag darken thaum lub hnub ci. Thaum lub teeb ci ploj mus, nws rov qab ci dua. Qhov no yog ua tau vim hais tias cov nyiaj halide crystals nyob rau hauv ua hauj lwm.
Nyob rau hauv ib txwm muaj xwm txheej, nws ua rau cov lo ntsiab muag zoo kawg nkaus pob tshab. Thaum raug tshav ntuj, cov nyiaj hauv cov siv lead ua yog sib cais, thiab cov nyiaj dawb ua cov ntaub ntawv me me hauv lub lens. Cov nyiaj me me no tsis sib xws, sib cuam tshuam clumps uas tsis tuaj yeem xa lub teeb tab sis nqus nws, ua rau lub lens darkening. Thaum lub teeb qis, cov siv lead ua hloov pauv thiab lub lens rov qab los rau nws lub teeb ci.
