Photochromic lens, tseem hu ua lub teeb pom kev zoo lens, yog ua raws li kev xav ntawm reversible cov tshuaj tiv thaiv ntawm lub teeb thiab xim sib hloov.Photochromic lens tuaj yeem ua kom tsaus ntuj hauv qab hnub ci lossis ultraviolet lub teeb.Nws tuaj yeem thaiv lub teeb muaj zog thiab nqus ultraviolet lub teeb, nrog rau absorbing pom lub teeb nruab nrab.Rov qab rau hauv qhov tsaus ntuj, nws tuaj yeem rov qab kho lub xeev meej thiab pob tshab, kom ntseeg tau lub teeb pom kev ntawm lub lens.Yog li ntawd, photochromic lo ntsiab muag yog tsim rau siv sab hauv tsev thiab sab nraum zoov tib lub sijhawm los tiv thaiv kev puas tsuaj rau lub qhov muag los ntawm tshav ntuj, lub teeb ultraviolet, thiab glare.
Feem ntau, cov xim tseem ceeb ntawm photochromic lo ntsiab muag yog grey thiab xim av.
Photochromic Grey:
Nws tuaj yeem nqus tau lub teeb infrared thiab 98% ntawm lub teeb ultraviolet.Thaum saib cov khoom los ntawm cov lo ntsiab muag grey, cov xim ntawm cov khoom yuav tsis hloov, tab sis cov xim yuav tsaus dua, thiab lub teeb ci yuav raug txo kom zoo.
Photochromic xim av:
Nws tuaj yeem nqus tau 100% ntawm ultraviolet rays, lim xiav lub teeb, txhim kho qhov pom kev sib txawv thiab pom tseeb, thiab pom kev ci ntsa iab.Nws yog qhov tsim nyog rau hnav hauv huab cua hnyav lossis huab cua huab cua, thiab yog qhov kev xaiv zoo rau cov neeg tsav tsheb.
Yuav ua li cas txiav txim photochromic lo ntsiab muag zoo los yog phem?
1. Cov xim hloov ceev: Cov xim hloov tau zoo muaj cov xim hloov ceev ceev, tsis muaj teeb meem los ntawm qhov tseeb mus rau qhov tsaus ntuj, lossis los ntawm tsaus mus rau qhov pom tseeb.
2. Qhov tob ntawm cov xim: qhov muaj zog ntawm ultraviolet rays ntawm lub lens zoo photochromic, cov xim yuav tsaus dua.Ordinary photochromic lo ntsiab muag yuav tsis tuaj yeem ncav cuag xim sib sib zog nqus.
3. Ib khub ntawm photochromic lo ntsiab muag nrog lub hauv paus tib lub hauv paus xim thiab synchronized xim hloov ceev thiab qhov tob.
4. Zoo xim hloov endurability thiab ntev.
Hom ntawm photochromic lens:
Nyob rau hauv lub sij hawm ntawm cov txheej txheem ntau lawm, muaj ob hom ntawm photochromic lo ntsiab muag: Los ntawm cov khoom, thiab los ntawm txheej (spin txheej / dipping txheej).
Niaj hnub no, qhov nrov photochromic lo ntsiab muag los ntawm cov khoom siv feem ntau yog 1.56 index, thaum lub lens photochromic ua los ntawm txheej muaj ntau txoj kev xaiv, xws li 1.499/1.56/1.61/1.67/1.74/PC.
Cov kev txiav xiav xiav tau muab tso rau hauv lub lens photochromic los muab kev tiv thaiv ntau dua rau lub qhov muag.
Kev ceev faj rau kev yuav cov lenses photochromic:
1. Yog hais tias qhov sib txawv diopter ntawm ob lub qhov muag yog ntau tshaj 100 degrees, nws raug nquahu kom xaiv lub lens photochromic los ntawm txheej, uas yuav tsis ua rau cov xim sib txawv ntawm lub lens discoloration vim qhov txawv thickness ntawm ob lo ntsiab muag.
2. Yog hais tias lub lens photochromic hnav rau ntau tshaj ib xyoos, thiab ib qho puas lawm thiab yuav tsum tau hloov, nws raug nquahu kom hloov ob qho tib si ua ke, kom cov nyhuv discoloration ntawm ob lub lo ntsiab muag yuav tsis txawv vim qhov sib txawv siv lub sij hawm ntawm ob lo ntsiab muag.
3. Yog hais tias koj muaj lub siab intraocular siab los yog glaucoma, tsis txhob hnav photochromic lo ntsiab muag los yog looj tsom iav dub.
Daim Ntawv Qhia Txog Kev Hnav Xim Hloov Zaj Duab Xis hauv Lub Caij Ntuj No:
Lub lens photochromic feem ntau kav ntev npaum li cas?
Nyob rau hauv cov ntaub ntawv ntawm kev saib xyuas zoo, qhov kev ua tau zoo ntawm photochromic lo ntsiab muag tuaj yeem khaws cia rau 2 mus rau 3 xyoos.Lwm cov lo ntsiab muag zoo tib yam tseem yuav oxidize thiab tig daj tom qab siv txhua hnub.
Nws puas yuav hloov xim tom qab lub sijhawm?
Yog tias lub lens hnav rau lub sijhawm, yog tias cov txheej txheem zaj duab xis ntog los yog lub lens hnav, nws yuav cuam tshuam rau kev ua haujlwm ntawm cov xim ntawm cov duab photochromic, thiab cov xim yuav tsis sib xws;Yog hais tias lub discoloration tob rau ntev, cov nyhuv discoloration kuj yuav cuam tshuam, thiab tej zaum yuav tsis ua hauj lwm discoloration los yog nyob rau hauv ib tug maub lub sij hawm ntev.Peb hu lub lens photochromic tau "tuag".
Nws puas yuav hloov xim rau hnub pos huab?
Kuj tseem muaj cov kab hluav taws xob ultraviolet nyob rau hnub huab cua, uas yuav ua kom cov xim tsis zoo hauv lub lens ua haujlwm.Lub zog ntawm ultraviolet rays, qhov sib sib zog nqus ntawm cov xim;qhov siab dua qhov kub, qhov sib dua ntawm cov xim.Qhov kub ntawm lub caij ntuj no tsis tshua muaj, lub lens ploj zuj zus thiab cov xim sib sib zog nqus.
Universe Optical muaj ntau yam ntawm photochromic lo ntsiab muag, rau cov ntsiab lus thov mus rau:
