Lub lens photochromic, tseem hu ua lub lens teb teeb, yog ua raws li txoj kev xav ntawm kev sib pauv ntawm lub teeb thiab xim. Lub lens photochromic tuaj yeem tsaus sai sai hauv qab lub hnub ci lossis lub teeb ultraviolet. Nws tuaj yeem thaiv lub teeb muaj zog thiab nqus lub teeb ultraviolet, nrog rau kev nqus lub teeb pom kev tsis muaj zog. Rov qab rau hauv qhov tsaus ntuj, nws tuaj yeem rov qab tau lub xeev meej thiab pob tshab sai sai, ua kom lub teeb xa mus rau lub lens. Yog li ntawd, cov lens photochromic yog qhov tsim nyog rau kev siv sab hauv tsev thiab sab nraum zoov tib lub sijhawm kom tiv thaiv kev puas tsuaj rau lub qhov muag los ntawm lub hnub ci, lub teeb ultraviolet, thiab lub teeb ci ntsa iab.
Feem ntau, cov xim tseem ceeb ntawm cov iav photochromic yog xim grey thiab xim av.
Xim av Photochromic:
Nws tuaj yeem nqus tau lub teeb infrared thiab 98% ntawm lub teeb ultraviolet. Thaum saib cov khoom los ntawm cov iav grey, cov xim ntawm cov khoom yuav tsis hloov pauv, tab sis cov xim yuav tsaus dua, thiab lub zog ntawm lub teeb yuav raug txo qis.
Xim av Photochromic:
Nws tuaj yeem nqus tau 100% ntawm cov teeb ultraviolet, lim lub teeb xiav, txhim kho qhov sib piv thiab qhov pom tseeb, thiab qhov kaj ntawm lub zeem muag. Nws tsim nyog rau hnav hauv huab cua phem heev lossis huab cua pos huab, thiab yog qhov kev xaiv zoo rau cov neeg tsav tsheb.
Yuav ua li cas txiav txim siab seb cov iav photochromic zoo lossis phem?
1. Qhov hloov xim sai: Cov iav hloov xim zoo muaj qhov hloov xim sai, tsis hais ntawm qhov meej mus rau qhov tsaus ntuj, lossis ntawm qhov tsaus ntuj mus rau qhov tseeb.
2. Qhov tob ntawm xim: qhov muaj zog ntawm cov duab ci ultraviolet ntawm lub lens photochromic zoo, qhov tsaus dua xim yuav. Cov lens photochromic ib txwm yuav tsis ncav cuag cov xim tob.
3. Ib khub iav tsom iav photochromic uas muaj tib xim thiab tib lub sijhawm hloov xim ceev thiab tob.
4. Kev hloov xim zoo thiab lub neej ntev.
Cov hom lens photochromic:
Hais txog cov txheej txheem tsim khoom, muaj ob hom lens photochromic: Los ntawm cov khoom siv, thiab los ntawm txheej (spin coating / dipping coating).
Niaj hnub no, cov iav photochromic nrov los ntawm cov khoom siv feem ntau yog 1.56 index, thaum cov iav photochromic ua los ntawm txheej muaj ntau txoj kev xaiv, xws li 1.499 / 1.56 / 1.61 / 1.67 / 1.74 / PC.
Lub luag haujlwm txiav xiav tau koom ua ke hauv cov iav photochromic los muab kev tiv thaiv ntau dua rau lub qhov muag.
Cov kev ceev faj rau kev yuav cov iav photochromic:
1. Yog tias qhov sib txawv ntawm diopter ntawm ob lub qhov muag ntau dua 100 degrees, nws raug nquahu kom xaiv cov iav photochromic ua los ntawm kev txheej, uas yuav tsis ua rau muaj qhov sib txawv ntawm cov xim sib txawv ntawm lub lens vim qhov sib txawv tuab ntawm ob lub lens.
2. Yog tias cov iav tsom iav photochromic tau hnav ntau tshaj ib xyoos, thiab ib qho puas lawm thiab xav tau hloov, nws raug pom zoo kom hloov ob qho tib si ua ke, kom qhov cuam tshuam ntawm ob lub iav tsom iav yuav tsis txawv vim lub sijhawm siv sib txawv ntawm ob lub iav tsom iav.
3. Yog tias koj muaj ntshav siab hauv qhov muag lossis mob glaucoma, tsis txhob hnav cov tsom iav photochromic lossis cov tsom iav dub.
Ib Daim Ntawv Qhia Txog Kev Hnav Cov Yeeb Yaj Kiab Hloov Xim Thaum Lub Caij Ntuj No:
Cov tsom iav photochromic feem ntau siv tau ntev npaum li cas?
Yog tias muaj kev saib xyuas zoo, cov iav tsom iav photochromic tuaj yeem ua haujlwm tau 2 txog 3 xyoos. Lwm cov iav tsom iav ib txwm kuj yuav oxidize thiab tig daj tom qab siv txhua hnub.
Puas yuav hloov xim tom qab ib lub sijhawm?
Yog tias lub lens raug hnav rau ib lub sijhawm, yog tias txheej zaj duab xis poob tawm lossis lub lens raug hnav, nws yuav cuam tshuam rau kev ua haujlwm ntawm cov yeeb yaj kiab photochromic discoloration, thiab qhov discoloration yuav tsis sib xws; yog tias qhov discoloration tob rau lub sijhawm ntev, qhov cuam tshuam discoloration kuj yuav raug cuam tshuam, thiab yuav muaj kev ua tsis tiav discoloration lossis nyob hauv qhov tsaus ntuj ntev. Peb hu ua photochromic lens "tuag".
Puas yuav hloov xim rau hnub uas muaj huab?
Kuj tseem muaj cov teeb ultraviolet thaum hnub uas muaj huab, uas yuav ua rau lub lens hloov xim kom ua haujlwm tau. Cov teeb ultraviolet muaj zog npaum li cas, qhov hloov xim yuav tob zuj zus; qhov kub siab dua, qhov hloov xim yuav sib dua. Qhov kub qis thaum lub caij ntuj no, lub lens yuav ploj qeeb qeeb thiab xim yuav tob zuj zus.
