Tib neeg tau swm rau lub hnub ci ci mus txog ntau lab xyoo, thiab tsuas tau pib siv cov khoom cuav pom ze li ntawm 100 xyoo. Lub cev tsis zoo ntawm lub teeb pom kev yuav ua rau ntau yam teeb meem, xws li qhov muag nkees thiab myopia. Qhov no yog vim hais tias cov duab hluav taws xob ntawm cov khoom neeg tsim hluav taws xob tsis zoo sib txawv los ntawm lub hnub ci spectrum. Yog tias cov thev naus laus zis ntawm cov khoom siv hluavtaws teeb pom kev zoo tuaj yeem txhim kho kom nws nyob ze rau lub hnub ci spectrum li sai tau, nws yuav zoo heev txo qhov tshwm sim ntawm teeb meem pom.
Tam sim no, qhov teeb meem ntawm myopia hauv cov menyuam yaus thiab cov tub ntxhais hluas tau nce xyoo los ntawm xyoo, muaj qhov xwm txheej siab, thiab cov hnub nyoog yau dua, uas tau dhau los ua teeb meem uas tsis tuaj yeem tsis quav ntsej rau peb cov kev nyab xeeb kev noj qab haus huv. Raws li kev sojntsuam Xyoo 2018 Myopia ntawm Cov Menyuam thiab Cov Hluas uas luam tawm los ntawm National Health Commission, qhov feem pua myopia ntawm cov menyuam yaus thiab cov hluas nyob thoob tebchaws yog 53.6%. Ntawm lawv, 14.5% ntawm cov menyuam muaj hnub nyoog 6 xyoo, 36.0% ntawm cov tub ntxhais kawm theem pib, 71.6% ntawm cov tub ntxhais kawm theem siab, thiab 81.0% ntawm cov tub ntxhais kawm theem siab. Txoj haujlwm ntawm kev tiv thaiv thiab tswj ntawm myopia yog qhov nyuaj.
Qhov teeb meem ntawm myopia hauv menyuam yaus thiab tub ntxhais hluas kuj tau nyiam lub teb chaws. Cov thawj coj hauv tebchaws tau ua qhov kev qhia tseem ceeb: Tag nrho lub zej zog yuav tsum nqis tes los saib xyuas cov menyuam' s lub qhov muag thiab cia lawv muaj lub neej tom ntej. Tom qab," Kev Npaj Ua rau Kev Tiv Thaiv thiab Kev Tiv Thaiv ntawm Myopia hauv Cov Menyuam thiab Cov Hluas" ua ke muab los ntawm ntau lub tuam tsev tso cov hom phiaj tswj hwm tus kabmob myopia ntawm cov menyuam muaj 6-xyoo nyob hauv kuv lub tebchaws txog li 3% los ntawm 2030, thiab suav nrog kev tiv thaiv myopia thiab tswj kev ua haujlwm hauv kev txheeb xyuas. Cov teeb tsa hluav taws xob puv xim rau kev tiv thaiv myopia hauv chav kawm tsev kawm raug txhawb.
Muaj ntau ntau yam cuam tshuam rau kev pom kev noj qab haus huv ntawm menyuam yaus thiab cov hluas. Ib qho ntawm cov ntsiab lus tseem ceeb yog qhov tsis tsim nyog hauv chav kawm teeb pom kev zoo. Raws li qhov tseem ceeb cuam tshuam ncaj qha rau lub qhov muag noj qab haus huv ntawm cov tub ntxhais kawm, chav ua lub teeb pom kev zoo yog nyiam cov pej xeem. Lub chav kawm teeb pom kev zoo hauv chav kawm tsis tsuas tuaj yeem txo qhov pom kev qias neeg ntawm cov tub ntxhais kawm, kho qhov kev sib dhos ntawm tib neeg lub cev, txhim kho tib neeg' s lub siab, tab sis kuj txhim kho kev ua tau zoo. Yog li ntawd, yuav ua li cas tsim kev nyob nyab xeeb thiab kom lub teeb ci zoo dua qub tau dhau los ua qhov ncauj lus tseem ceeb ntawm kev sib tham. Hauv lub sijhawm thaum ntxov, cov hlab LED siv hauv chav kawm feem ntau siv lub teeb pom kev txias txias LED tubes, uas muaj qhov tsis xws luag vim kev ua haujlwm. Lub tsev kawm ntawv cov chav kawm tiv thaiv myopia los ntawm cov yeeb yaj kiab uas muaj kev coj ua, uas kov yeej qhov tsis txaus thiab yog nyob ze rau tshav ntuj. Nrog rau kev paub tab thiab kev loj hlob ntawm cov thev naus laus zis LED, kev tsim ua tsev kawm ntawv cov hluav taws xob puv LED cov raj uas zoo li lub hnub ci hluav taws xob tau dhau los ua qhov chaw kub hauv kev lag luam. Puv-spectrum LED yuav dhau los ua qhov hluav taws xob ntxiv ntawm kev lag luam teeb pom kev zoo, thiab nws cov peev xwm xav tau yog loj heev. Yog li ntawd, ntau cov tuam txhab tsim khoom muaj cov kev tshawb fawb thiab kev tsim kho thiab kev teeb tsa.
Muaj ob txoj hauv kev los ua kom muaj kev tiv thaiv myopia hauv chav kawm hauv tsev kawm ntawv nrog kev ua kom muaj lub ntsej muag puv ntoob coj teeb ci.
1. Kev daws teeb meem LED paj yeeb LED muaj lub teeb pom kev zoo heev, uas yuav luag ze rau lub hnub ci. Hauv lub xeev ntawm 5000K xim kub, Ra 100; Hauv lub xeev ntawm 3000K xim kub, Ra 97.
2. Lwm qhov sib txig xiav + cov xim daws teeb meem phosphor, Ra 96 ntawm ib qho xim kub ntawm 5000K; Ra 97 ntawm cov xim kub ntawm 2700K, yog lub hnub qub cov khoom lag luam nrog lub siab lub teeb ci thiab cov nqi tsim nyog hauv tsev neeg muaj peev xim tag nrho cov khoom.
Qhov kev tawg ntawm tag nrho-spectrum LED teeb hlaws teeb yuav tsav kev txhim kho ntawm nqes dej puv-LED teeb pom kev zoo, uas yog qhov muaj txiaj ntsig zoo dua rau kev nce qib mus rau hauv tsev kawm, tsev kawm ua haujlwm, thiab chav tshawb fawb. Vim nws cov txiaj ntsig loj, nws yog qhov yooj yim los txhawb. Tej zaum nws yog lub sijhawm zoo rau nce qib coj ntsuas. Nyob rau tib lub sijhawm, nws yuav txhawb txoj kev loj hlob ntawm kev lag luam cuam tshuam.
