Khoom nta
1) Lub ntsej muag ci ntsa iab yog dab tsi?
BifiFocals yog lo ntsiab lus nrog ob lub hwj chim uas raug. Cov xyoob ntoo yog cov uas tau muab rau cov etbyopes
uas yuav tsum tau kho rau myopia (ze rau siab) lossis hyperopia (farsightedness) nrog lossis tsis muaj kev kho rau cov tsis muaj zog los ntawm cov lens lossis mob hlwb). Lub hom phiaj bifocal yog los muab kev tsom xam zoo ntawm qhov kev sib nrug ntawm qhov deb thiab ze lub zeem muag.
Feem ntau, koj saib thiab dhau ntawm qhov deb ntawm lub lens thaum tsom rau cov ntsiab lus deb, thiab koj
saib thiab dhau ntawm bifocal ntu ntawm lub lens thaum tsom cov khoom nyeem ntawv lossis khoom tsis pub dhau 18 xyoo
Nti ntawm koj lub qhov muag.Nws feem ntau lees txais tias Benjamin Franklin tau tsim lub Bifocal. Cov Bifocal feem ntau yog ncaj saum 28 Bifocal uas muaj txoj kab ncaj nraim thoob plaws nrog 28MM vojvoog. Muaj ob peb ntau yam ntawm Ncaj Sab saum toj Bifocals muaj nyob rau hnub no suav nrog: Ncaj nraim rau sab saum toj 45 thiab tus thawj Franklin Seg) uas tau khiav ua tiav qhov dav ntawm lub lens.
Ntxiv nrog rau qhov ncaj ncaj qha rau cov kab ncaj qha muaj qhov sib nrug sib nrug nrog rau puag ncig 22, puag ncig 24, puag ncig 25
Thiab xyaw nrog round 28 (tsis muaj qhov tseeb ntu).
Qhov kom zoo rau ntu ntu yog tias muaj tsawg dua cov duab dhia ua ib qho kev hloov ntawm qhov kev ncua deb mus rau qhov ze ntawm lub lens.
2)Cov yam ntxwv ntawm Cov Duab Ci Hluav Taws Xob
Photochromic lo ntsiab muag tau muaj nyob rau hauv yuav luag txhua lub tshuab cov ntaub ntawv thiab tsim qauv, suav nrog cov qib siab, bifocal thiab kev ua tau zoo. Ib qho txiaj ntsig ntxiv ntawm cov duab ci ntsa iab yog tias lawv thaiv koj lub qhov muag los ntawm 100 feem pua ntawm lub hnub poob kev zoo UVA thiab UVB rays.
Vim tias ib tus neeg lub neej raug lub hnub ci thiab UV hluav taws xob tau cuam tshuam nrog kev ua si tom qab lub neej, nws yog lub tswv yim zoo rau cov menyuam tsom iav rau cov neeg laus.
3) HC, HMC thiab SHC li cas?
| Tawv tawv | A txheej / Txuj Ci Ntau Txheej | Super Hydrophobic Txheej |
| ua rau lub lens tsis muaj zog thiab ua rau muaj kev puas tsuaj tsis kam | nce cov kev sib txuas ntawm lub lens thiab txo qhov chaw sib txawv | Ua rau lub lens waterproof, cov tshuaj tua kab mob, tiv thaiv plam thiab roj tsis kam |
