Cov iav tsom iav photochromic muab faib ua ob hom: cov iav tsom iav photochromic substrate (hu ua "monomer photo grey") thiab cov iav tsom iav photochromic txheej zaj duab xis (hu ua "spin coating") raws li qhov sib txawv ntawm lub lens.
Lub lens photochromic substrate yog ib yam tshuaj uas ntxiv nrog silver halide rau hauv lub lens substrate. Siv cov tshuaj ionic ntawm silver halide, nws raug decomposed rau hauv silver thiab halogen nyob rau hauv lub teeb muaj zog stimulation kom xim lub lens. Tom qab lub teeb ua qaug zog, nws raug sib xyaw ua ke rau hauv silver halide., xim yuav sib dua. Iav photochromic lens siv cov thev naus laus zis no.
Cov iav tsom iav uas muaj txheej photochromic raug kho tshwj xeeb hauv cov txheej txheem txheej lens. Piv txwv li, cov tshuaj spiropyran siv los ua cov txheej txheej ceev ceev rau ntawm qhov chaw ntawm lub lens. Raws li qhov muaj zog ntawm lub teeb thiab cov duab ultraviolet, qhov qhib thiab kaw ntawm cov qauv molecular nws tus kheej yog siv los ua kom tiav cov nyhuv ntawm kev dhau lossis thaiv lub teeb.
Kev Taw Qhia Txog Kev Tsim Khoom
Thaum xaiv cov tsom iav Photochromic, nws yog qhov tseem ceeb uas yuav tsum xav txog cov yam ntxwv ntawm lub tsom iav, kev siv cov tsom iav, thiab tus neeg xav tau xim. Cov tsom iav Photochromic kuj tseem tuaj yeem ua rau ntau yam xim, xws li grey, xim av thiab lwm yam.
1. Lub lens grey: tuaj yeem nqus tau cov duab infrared thiab 98% ntawm cov duab ultraviolet. Qhov zoo tshaj plaws ntawm lub lens grey yog tias cov xim qub ntawm qhov chaw yuav tsis hloov los ntawm lub lens, thiab qhov txaus siab tshaj plaws yog tias nws tuaj yeem txo qhov muaj zog ntawm lub teeb zoo heev. Lub lens grey tuaj yeem nqus tau txhua yam xim spectrum, yog li qhov chaw saib yuav tsuas yog tsaus ntuj xwb, tab sis yuav tsis muaj qhov tsis zoo ntawm chromatic aberration, qhia txog kev xav tiag tiag. Nws yog xim nruab nrab, haum rau txhua tus neeg.
2. Cov tsom iav xim liab: Qhov no yog xim uas pom ntau heev. Nws nqus tau 95% ntawm cov teeb UV. Yog tias siv ua tsom iav rau kev kho qhov muag, cov poj niam uas yuav tsum hnav lawv ntau zaus yuav tsum xaiv cov tsom iav xim liab dawb, vim tias cov tsom iav xim liab dawb nqus tau cov teeb ultraviolet zoo dua thiab tuaj yeem txo qhov ci ntsa iab tag nrho, yog li tus neeg hnav yuav xis nyob dua.
3. Cov tsom iav xim av daj: Ib yam li cov tsom iav xim liab, lawv nrov dua nrog cov poj niam laus vim lawv cov xim tsaus dua.
4. Lub lens xim av: Nws tuaj yeem nqus tau 100% ntawm cov teeb ultraviolet, thiab lub lens xim av tuaj yeem lim tawm ntau lub teeb xiav, uas tuaj yeem txhim kho qhov sib piv thiab qhov pom tseeb, yog li nws nrov heev ntawm cov neeg hnav. Tshwj xeeb tshaj yog thaum muaj huab cua phem lossis pos huab, qhov hnav zoo dua. Feem ntau, nws tuaj yeem thaiv lub teeb ci ntsa iab ntawm qhov du thiab ci ntsa iab, thiab tus neeg hnav tseem tuaj yeem pom qhov zoo, uas yog qhov kev xaiv zoo tshaj plaws rau tus tsav tsheb. Rau cov neeg mob hnub nyoog nruab nrab thiab cov neeg laus uas muaj kev pom siab tshaj 600 degrees, qhov tseem ceeb tuaj yeem muab.
5. Cov tsom iav xiav kaj: Cov tsom iav xiav hnub ci tuaj yeem hnav thaum ua si ntawm ntug hiav txwv. Cov tsom iav xiav tuaj yeem lim cov xim xiav uas dej hiav txwv thiab lub ntuj cuam tshuam tau zoo. Yuav tsum tsis txhob siv cov tsom iav xiav thaum tsav tsheb vim tias nws ua rau peb nyuaj rau paub qhov txawv ntawm cov xim ntawm cov teeb liab tsheb.
6. Lub lens ntsuab: Lub lens ntsuab tuaj yeem nqus tau lub teeb infrared thiab 99% ntawm cov teeb ultraviolet, ib yam li lub lens grey. Thaum nqus lub teeb, nws ua kom lub teeb ntsuab ncav cuag lub qhov muag ntau tshaj plaws, yog li nws muaj qhov txias thiab xis nyob thiab tsim nyog rau cov neeg uas muaj qhov muag nkees.
7. Lub lens daj: Nws tuaj yeem nqus tau 100% ntawm cov teeb ultraviolet, thiab tuaj yeem cia cov teeb infrared thiab 83% ntawm lub teeb pom kev nkag mus rau hauv lub lens. Qhov tseem ceeb tshaj plaws ntawm cov lens daj yog tias lawv nqus feem ntau ntawm lub teeb xiav. Vim tias thaum lub hnub ci ntsa iab los ntawm huab cua, nws feem ntau tshwm sim ua lub teeb xiav (uas tuaj yeem piav qhia vim li cas lub ntuj xiav). Tom qab lub lens daj nqus lub teeb xiav, nws tuaj yeem ua rau qhov chaw ntuj pom tseeb dua. Yog li ntawd, lub lens daj feem ntau siv ua "lim" lossis siv los ntawm cov neeg yos hav zoov thaum yos hav zoov. Hais lus nruj me ntsis, cov lens no tsis yog lub lens hnub vim tias lawv tsis tshua txo lub teeb pom kev, tab sis thaum lub sijhawm pos huab thiab tsaus ntuj, cov lens daj tuaj yeem txhim kho qhov sib piv thiab muab kev pom tseeb dua, yog li lawv kuj hu ua cov tsom iav pom kev hmo ntuj. Qee cov tub ntxhais hluas hnav cov tsom iav daj "tsom iav" ua kho kom zoo nkauj, uas yog ib qho kev xaiv rau cov neeg uas muaj glaucoma thiab cov neeg uas xav tau kev txhim kho qhov ci ntsa iab.
Nrog rau qhov xav tau ntawm lub neej niaj hnub no, lub luag haujlwm ntawm cov tsom iav xim tsis yog tsuas yog lub luag haujlwm ntawm kev tiv thaiv qhov muag xwb, nws tseem yog ib daim duab kos duab. Ib khub tsom iav xim thiab cov khaub ncaws tsim nyog tuaj yeem ua rau tus neeg muaj tus cwj pwm zoo kawg nkaus.
