Ib qho ntawm cov lus nug feem ntau cov neeg tau hnov thaum lawv tau txais lawv lub lo ntsiab muag yog, "Koj xav tau dab tsi refractive index?"Kuv ntseeg tias muaj coob tus neeg tsis to taub cov lus no, cia peb kawm txog nws hnub no!
Ntau tus neeg hauv lub neej niaj hnub no ntseeg tias cov tsom iav kim dua, qhov zoo dua!Ntau tus kws kho qhov muag, tuav qhov kev xav ntawm cov neeg siv khoom, feem ntau siv qhov ntsuas qhov muag tsis pom kev los ua kom tus nqi ntawm cov iav kom tau txais txiaj ntsig zoo dua nyiaj txiag.Ntawd yog, qhov siab dua qhov ntsuas qhov ntsuas pom, lub lens thinner, thiab tus nqi kim dua!
Lub ntsiab kom zoo dua ntawm high-refractive lo ntsiab muag yog lawv thinness.Cov neeg siv khoom hauv kev xaiv lo ntsiab muag, yuav tsum xaiv raws li qhov sib txawv ntawm qhov muag kom haum rau lawv tus kheej, kev ua tau zoo ntawm lub lens, qhov muag tsis pom kev ntawm qhov ntsuas siab refractive tsis xav tau, tsim nyog yog qhov tseem ceeb tshaj plaws!
Cov lo ntsiab muag zoo kho qhov muag yuav tsum xa mus rau lo ntsiab muag nrog cov khoom siv kho qhov muag zoo, uas tau cuam tshuam hauv kev xa tawm siab, siab clarity, me me dispersion, zoo hnav tsis kam, zoo heev txheej thiab kev tiv thaiv zoo.
Feem ntau qhov ntsuas qhov ntsuas ntawm lub lo ntsiab muag suav nrog 1.49, 1.56, 1.61, 1.67, 1.74, 1.8, 1.9.
Los ntawm tus kws tshaj lij kev pom los xaiv qhov refractive index feem ntau raws li cov kev xav hauv qab no:
1. Degree ntawm myopia.
Myopia tuaj yeem muab faib ua myopia me (nyob rau hauv 3.00 degrees), nruab nrab myopia (nruab nrab ntawm 3.00 thiab 6.00 degrees), thiab siab myopia (siab dua 6.00 degrees).
Feem ntau hais lus teeb thiab nruab nrab MYOPIA (400 degrees tsawg dua) CHOICE REFRACTIVE INDEX YOG 1.56 OK, (300 degrees mus rau 600 degrees) IN 1.56 LOSSIS 1.61 ob hom REFRACTIVE index xaiv, 600 degrees saum toj no tuaj yeem txiav txim siab 1. lens.
Qhov siab dua qhov refractive index yog, qhov ntau refraction tshwm sim tom qab lub teeb dhau los ntawm lub lens, thiab lub lens yog thinner.Txawm li cas los xij, qhov siab dua qhov refractive index yog, qhov loj dua qhov tshwm sim dispersion yog, yog li lub siab refractive index lens muaj tus lej Abbe tsawg.Nyob rau hauv lwm yam lus, thaum lub refractive index siab dua, lub lens yog nyias, tab sis thaum saib tej yam, lub vividness ntawm cov xim tsis yog li nplua nuj piv nrog rau 1.56 refractive index.Dab tsi tau hais ntawm no tsuas yog qhov sib txawv me ntsis hauv kev sib piv cov txheeb ze.Nrog rau tam sim no technology, lub lens nrog siab refractive index kuj zoo heev nyob rau hauv lub zeem muag.High refractive index lo ntsiab muag feem ntau yog siv rau ntau txhiab degrees.
2. Lub ntsiab lus xav tau.
Qhov kev xaiv ntawm refractive index raws li cov degree ntawm myopia tsis yog kiag li, tab sis yuav tsum tau ua ke nrog kev xaiv ntawm lub thav duab thiab qhov teeb meem tiag tiag ntawm lub qhov muag los txiav txim.
Tam sim no myopic degree feem ntau siab, ntawm tsib mus rau rau baidu's myopia, qis refractive Performance index ntawm lub lens yuav tuab, tus txheeb ze qhov hnyav yuav yog ob peb loj, ntawm qhov no, yog tias nrhiav kev zoo nkauj qib siab dua, peb xav ntau dua 1.61. refractive index, ntxiv rau thaum xaiv ib daim duab thav duab kom tsis txhob loj lub thawv hom, yog li kev, tsom iav degree ntawm kev zoo nkauj thiab kev nplij siab kuj zoo.
Cov ntsiab lus: Kev xaiv ntawm qhov ntsuas qhov cuam tshuam yuav tsum yog raws li cov lus qhia ntawm tus kws kho qhov muag, raws li qhov ntsuas ntawm myopia, thav duab loj, kev xav tau zoo nkauj, pom kev nplij siab, noj nyiaj thiab lwm yam kev xav, tsim nyog yog qhov tseem ceeb tshaj plaws.
