SETO 1.56 round-top bifocal lens HMC

Lus piav qhia luv luv:

Raws li lub npe qhia lub puag ncig bifocal yog puag ncig ntawm sab saum toj.Lawv tau tsim los pab cov neeg hnav mus txog qhov chaw nyeem ntawv yooj yim dua.Txawm li cas los xij, qhov no txo qhov dav ntawm qhov ze ze ntawm qhov pom muaj nyob rau sab saum toj ntawm ntu.Vim li no, round bifocals tsis tshua nyiam dua D Seg.
Kev nyeem ntawv feem ntau muaj nyob rau hauv 28mm thiab 25mm qhov ntau thiab tsawg.R28 yog 28mm dav ntawm qhov chaw thiab R25 yog 25mm.

1.Lub lens bifocal yog dab tsi?
Bifocal lo ntsiab muag yog hais txog lub lens uas muaj qhov sib txawv luminosity tib lub sijhawm, thiab faib lub lens rau hauv ob feem, sab sauv ntawm qhov pom qhov pom, thiab sab qis yog thaj tsam myopic.
Hauv ib lub lens bifocal, thaj chaw loj dua feem ntau yog thaj chaw deb, thaum thaj chaw myopic tsuas yog ib feem me me ntawm qhov qis, yog li qhov siv rau kev pom deb yog hu ua lub lens thawj, thiab qhov siv rau qhov ze ze hu ua sub. -lens.
Los ntawm qhov no peb tseem tuaj yeem nkag siab tias qhov txiaj ntsig ntawm lub lens bifocal yog tias nws tsis yog tsuas yog ua haujlwm kho qhov pom kev deb, tab sis kuj muaj cov haujlwm ntawm kev kho qhov muag ze ze.

2.Dab tsi yog lub lens puag ncig?
Round Top, kab tsis pom tseeb li hauv Flat Top.Nws tsis pom tab sis thaum hnav.Nws zoo li yuav pom tsawg dua.Nws ua haujlwm zoo ib yam li lub tiaj tiaj, tab sis tus neeg mob yuav tsum saib deb dua hauv lub lens kom tau txais qhov dav tib yam vim qhov zoo ntawm lub lens.

3.Dab tsi yog yam ntxwv ntawm bifocals?
Nta: muaj ob lub ntsiab lus focal ntawm lub lens, uas yog, lub lens me me nrog lub zog sib txawv superimposed ntawm lub lens zoo tib yam;
Siv rau cov neeg mob uas muaj presbyopia pom nyob deb thiab nyob ze ua ke;
Lub sab sauv yog lub luminosity thaum saib deb (qee zaum tiaj tus), thiab lub teeb qis yog lub luminosity thaum nyeem ntawv;
Qhov kev ncua deb yog hu ua lub hwj chim sab saud thiab nyob ze yog hu ua lub hwj chim qis, thiab qhov sib txawv ntawm lub hwj chim sab sauv thiab lub zog qis yog hu ua ADD (ntxiv lub zog).
Raws li cov duab ntawm cov khoom me me, nws tuaj yeem muab faib ua lub tiaj tiaj-sab saum toj bifocal, round-top bifocal thiab lwm yam.
Qhov zoo: cov neeg mob presbyopia tsis tas yuav hloov cov iav thaum lawv pom ze thiab deb.
Qhov tsis zoo: dhia tshwm sim thaum saib qhov deb thiab ze ntawm kev hloov pauv;
Los ntawm cov tsos, nws txawv ntawm lub lens zoo tib yam.

4. Qhov txawv ntawm HC, HMC thiab SHC yog dab tsi?

Txheej tawv	AR txheej / Hard txheej txheej	Super hydrophobic txheej
ua rau cov lo ntsiab muag uncoated tau yooj yim subjicted thiab raug khawb	tiv thaiv lub lens zoo los ntawm kev xav, txhim kho kev ua haujlwm thiab kev siab hlub ntawm koj lub zeem muag	ua rau lub lens waterproof, antistatic, anti plam thiab roj kuj
