Lub qhov muag zoo nkauj yog qhov "npau taws" zoo rau kev yos hav zoov cov neeg nyiam sib deev. Cov poj niam nyob rau hauv lub caij nyoog tshiab, thiab txawm tias cov txiv neej uas yog nyob rau hauv lub forefront ntawm kev loj hlob tiam sis, twb muaj ib tug zoo xav tau rau lub qhov muag kev zoo nkauj tuam txhab uas muag: mascara, eyeliner, qhov muag ntxoov ntxoo, txhua yam ntawm cov cuab yeej tswj tau yooj yim, ntawm chav kawm, peb kuj muaj. ib lub lens tiv tauj, nws tuaj yeem pab txhim kho tib neeg lub peev xwm kom tshem tawm cov thav duab hnyav thiab tuav lub ntsej muag zoo nkauj.
1. Tsis txhob ua rau koj ob lub qhov muag zoo nkauj
Ntau tus neeg yuav tsum tau siv sijhawm ntau "kev nkag siab" lawv lub ntsej muag thaum lawv tawm mus thaum sawv ntxov. Txhua tus saib xyuas cov neeg uas so lawv lub ntsej muag: Lawv tsis muaj daim tawv nqaij khaus, co toxins thiab nkag mus rau oxygen. Qhov tseeb, koj ob lub qhov muag xav tau huab cua dawb ntau dua li koj cov tawv nqaij.
Tshwj xeeb tshaj yog rau qee cov neeg uas feem ntau hnav cov lo ntsiab muag, txij li cov lo ntsiab muag ntawm cov neeg zoo li no nyob rau hauv kev sib cuag ncaj qha nrog lub cornea ntawm lub qhov muag ntev, yog tias cov khoom siv lo ntsiab muag tsis tuaj yeem ua kom lub qhov muag tuaj yeem nqus pa oxygen hauv huab cua, sib npaug rau inferior tshuaj pleev ib ce. Yog koj hnav nws ntev dua, qhov kev puas tsuaj loj dua rau koj ob lub qhov muag. Yog li ntawd, cov tshuaj tiv thaiv nrog cov pa oxygen permeability zoo li cov poj niam lub hnab kom zoo nkauj thiab yuav tsum tau dhau los ua qhov tsim nyog tshiab hauv peb lub neej.
2. High oxygen permeability, tso cai rau ob lub qhov muag ua pa dawb
Dab tsi yog qhov siab oxygen permeability? Yuav ntsuas nws li cas?
Thaum xaiv lub lens nrog siab oxygen permeability, oxygen permeability coefficient thiab oxygen permeability yog ob qho tseem ceeb tshaj plaws ntsuas. Cov pa oxygen permeability coefficient (DK) yog hais txog cov pa permeability ntawm cov khoom siv lens, thiab feem ntau siv oxygen permeability (DK / T) yog hais txog huab cua permeability ib chav thickness ntawm lub lens. Qhov siab dua cov pa permeability coefficient (DK) thiab cov pa permeability coefficient (DK / T), qhov siab dua cov pa permeability coefficient (DK / T) thiab cov pa oxygen permeability coefficient (DK / T), lub peev xwm ntawm cov pa oxygen ntau dua. qhov muag.
3.Yuav ua li cas xaiv "sib cuag lo ntsiab muag" nrog siab oxygen permeability?
Feem ntau ntawm cov khoom siv lo ntsiab muag nyob rau hauv kev ua lag luam siv cov dej uas muaj nyob rau hauv lub lens raws li cov cab kuj kom oxygenate lub qhov muag, tab sis tom qab hnav nws ntev, tsis muaj dej evaporation ntawm lub lens. Txhawm rau tswj hwm nws cov ntsiab lus dej qub, Nws yuav nqus cov kua muag los ntawm lub qhov muag los ntxiv "dej cov ntsiab lus" ntawm cov lo ntsiab muag, uas yuav ua rau "dryness" ntawm cov tub ntxhais kawm qhov muag.
Nws tsis cia siab rau cov ntsiab lus dej kom ua tiav cov pa permeability - nws yog qhov zoo tshaj plaws silicone hydrogel lens ntawm kev ua lag luam. Hom silicone hydrogel contact lens no txawv ntawm cov khoom siv tsis tshua muaj methacrylic nyob rau hauv kev ua lag luam, vim hais tias silicone hydrogel nyob rau hauv lub microscope, lub molecular qauv ntawm lub molecule yog teem nyob rau hauv ib qhov chaw "net", thiab cov pa oxygen nyob rau hauv cov huab cua yuav dawb do dhau. los ntawm cov "channels" kom ncav cuag koj lub cornea yam tsis tau tso dej los ua "cov cab kuj".
Hauv kev ua lag luam tam sim no, Aishenghua's silicone hydrogel contact lo ntsiab muag muaj cov pa oxygen permeability siab heev, thiab nws tseem yog tib lub chaw tsim khoom hauv tsev uas tau tawg los ntawm kev cuam tshuam txawv teb chaws thiab muaj peev xwm tsim cov tshuaj tiv thaiv silicone hydrogel. Kev siv thev naus laus zis thev naus laus zis, pab pawg ua haujlwm tau zoo, cov cuab yeej ua haujlwm thawj zaug, thiab cov txheej txheem tsim khoom nruj ua rau cov khoom siv lo ntsiab muag tsis yog tsuas yog muaj kev nyab xeeb, tab sis kuj nyiam, nyiam los ntawm cov neeg siv, thiab tus khub zoo tshaj plaws ntawm HJ EYEWEAR contact lens hom!
