Nrog lub hnub ci ntsa iab ntawm lub caij ntuj sov, kev tawm mus sab nraud feem ntau ua rau muaj kev xav tsis thoob.tsom iav dubTsis ntev los no tau dhau los ua qhov chaw muaj nyiaj tau los ntau hauv kev lag luam muag khoom tsom iav, thaum cov iav photochromic tseem yog qhov lav ntawm kev muag khoom lub caij ntuj sov. Kev ua lag luam thiab cov neeg siv khoom lees txais cov iav photochromic yog los ntawm lawv cov qauv, kev tiv thaiv lub teeb, thiab kev haum rau kev tsav tsheb ntawm ntau yam kev xav tau.
1. Vim li cas thiaj tsim nyog tiv thaiv qhov muag?
Lub teeb ultraviolet tuaj yeem muab faib ua UVA, UVB, thiab UVC:
UVC muaj qhov wavelength luv dua thiab raug nqus los ntawm txheej ozone hauv huab cua, yog li nws tsis yog qhov txhawj xeeb.
UVB, lub teeb ultraviolet nruab nrab, tuaj yeem ua puas tsuaj rau cov hlwb tawv nqaij los ntawm kev tshuaj lom neeg, ua rau muaj erythema thiab kub hnyiab.
UVA, lub teeb ultraviolet ntev ntev, ua rau daim tawv nqaij tawv sai sai yam tsis kub hnyiab, tab sis nws kuj ua rau muaj mob xws li keratitis.
Hauv ntiaj teb no, lub teeb ultraviolet ntev ntev yog 97% ntawm kev raug UV. Yog li, kev tiv thaiv tiv thaiv UVA thiab UVB hauv lub neej txhua hnub yog qhov tseem ceeb heev.
Lwm yam teeb meem yog qhov muag ntsais. Thaum huab cua ntshiab, tshwj xeeb tshaj yog thaum lub caij ntuj sov, qhov muag ntsais tsis yog tsuas yog cuam tshuam rau qhov pom kev meej xwb tab sis kuj ua rau qhov muag qaug zog.
Vim yog qhov keeb kwm yav dhau los no, qhov tseem ceeb ntawm kev xaiv cov iav photochromic uas muab ob qho tib si kho qhov muag thiab tiv thaiv lub teeb yog qhov pom tseeb.
2. Txhua tus neeg puas hnav taucov iav photochromic?
Ua ntej, nco ntsoov cov pab pawg hauv qab no uas tsis haum rau cov iav photochromic:
Cov menyuam yaus uas muaj qhov muag me me (hnub nyoog qis dua 6 xyoos) uas lawv lub qhov muag tseem tab tom loj hlob yuav raug cuam tshuam los ntawm kev siv lub qhov muag ntev.
Cov neeg uas muaj mob glaucoma xav tau lub teeb ci ntsa iab. Kev hnav tsom iav dub txo qhov kev raug lub teeb, uas tuaj yeem ua rau cov qhov muag loj tuaj, ua rau lub qhov muag siab dua, thiab ua rau mob.
Cov neeg uas muaj mob optic neuritis, vim tias hnav cov iav photochromic tuaj yeem ua rau mob o ntxiv vim yog cov hlab ntsha tsis zoo.
Lub teeb UV yeej ib txwm muaj, txawm tias lub caij lossis huab cua li cas los xij. Dua li ntawm cov pab pawg uas tau hais los saum toj no, cov tsom iav photochromic kuj tsim nyog rau txhua tus neeg.
3. Vim li cas cov tsom iav xim grey thiaj li nrov tshaj plaws hauv khw?
Cov tsom iav xim grey tuaj yeem nqus tau infrared thiab 98% ntawm cov teeb UV. Qhov zoo tshaj plaws ntawm cov tsom iav xim grey yog tias lawv tsis hloov cov xim qub ntawm ib puag ncig, ua rau lub teeb tsis ci ntsa iab. Cov tsom iav xim grey muab kev nqus dej sib npaug thoob plaws txhua qhov spectrum, yog li cov khoom zoo li tsaus dua tab sis tsis muaj kev cuam tshuam xim loj, muab qhov pom tseeb tiag tiag. Tsis tas li ntawd, xim grey yog xim nruab nrab uas haum rau txhua tus, ua rau nws nrov dua.
4. Cov txiaj ntsig ntawm cov hauv paus meej,cov tsom iav photochromic tiv thaiv lub teeb xiav?
Haum rau ntau yam xwm txheej hauv lub neej, hloov pauv ntawm sab hauv tsev thiab sab nraum zoov, ua haujlwm ob lub hom phiaj.
Sab hauv tsev/hmo ntuj lawv pom tseeb thiab pob tshab, sab nraum zoov lawv tsaus ntuj, muab kev tiv thaiv ob npaug tiv thaiv cov duab UV thiab lub teeb xiav uas ua rau puas tsuaj, txo qhov qaug zog.
Cov thev naus laus zis hloov zaj duab xis zoo heev ua kom muaj kev hloov xim sai thiab ruaj khov; nano anti-blue light technology ua rau cov lens ntshiab thiab tsis daj, ua kom pom kev zoo.
Raws li cov lus hais tias, "Yuav kom ua tau haujlwm zoo, ib tug yuav tsum xub ua kom nws cov cuab yeej ntse." Kev txhawb nqa cov khoom siv: cov qauv photochromic, cov khoom siv, thiab cov ntawv tshaj tawm lub thawv teeb pab txhawb kev txhawb nqa cov iav photochromic.
Kev nplij siab, kev tiv thaiv, thiab kev yooj yim yog peb lub ntsiab lus uas yuav tsum tau txhawb nqa ntau zaus thaum sib txuas lus nrog cov neeg siv khoom.
5. Yog cov lus qhia meej,cov tsom iav photochromic tiv thaiv lub teeb xiavzoo dua rau kev hnav khaub ncaws?
Ib qho ntawm cov ncauj lus kub tshaj plaws hauv kev noj qab haus huv ntawm qhov muag tam sim no yog kev tiv thaiv lub teeb xiav, thiab cov iav tsom iav ua haujlwm uas muaj peev xwm tiv thaiv lub teeb xiav yog nrov heev nrog cov neeg siv khoom. Kev puas tsuaj los ntawm UV yog qhov teeb meem thoob plaws hauv ib xyoos tab sis nws pom tseeb tshwj xeeb tshaj yog thaum lub caij ntuj sov kub, yog li qhov kev thov rau cov iav tsom iav photochromic yog ntev.
Txawm hais tias cov tsom iav photochromic muaj ntau xim, cov tsom iav grey zoo tshaj plaws rau hnav thom khwm. Sab nraum zoov, xim grey tob yog xim xis nyob tshaj plaws rau lub qhov muag; lawv phim nrog txhua lub thav tsom iav, ua rau lawv yog qhov kev xaiv ntau yam rau cov xim photochromic.
Vim muaj ntau yam refractive index xaiv, cov iav tsom iav photochromic uas muaj 1.56 thiab 1.60 refractive index muag tau zoo tshaj plaws hauv khw. Kev nce qhov muag ntawm Safety Guard 1.60 clear-base anti-blue light photochromic lenses tsis yog tsuas yog pab kom tus nqi xaj nruab nrab nce xwb tab sis kuj muaj cov txiaj ntsig zoo uas pab txhawb kev lag luam. Yog xav paub ntxiv txog cov cai muag khoom thiab kev txhawb nqa tom qab muag rau Safety Guard clear-base anti-blue light photochromic lenses, thov nrog tus neeg sawv cev muag khoom tham.
6. Kev ua haujlwm ntawm cov xim sib txawv ntawmcov iav photochromic?
| Xim tshuaj yej | Ua kom pom kev zoo dua thiab pom tseeb dua, ua haujlwm tau zoo hauv cov huab cua phem lossis pos huab, thiab yog qhov kev xaiv zoo tshaj plaws rau cov neeg tsav tsheb thiab cov neeg mob uas siv tshuaj ntau. |
