Bifocals pab nyob rau hauv lub xub ntiag

Nruam txoj kev loj hlob ntawm kev kho mob technology enables lab tus tib neeg thoob plaws hauv lub ntiaj teb no mus rov lawv txoj kev poob lub zeem muag thiab ua ib tug tag nrho lub neej. Ib tug ntawm cov pov thawj txoj kev mus tau deb ntawm presbyopia, uas tshwm sim nrog lub hnub nyoog nyob rau hauv feem ntau cov neeg yog cov siv ntawm ob los yog ntau tshaj officers ntawm tsom iav. Ntawm cov hoob kawm, qhov no yog tsis ib txwm yooj yim, thiab ntawm no tuaj rau cov kev pab ntawm bifocals, uas muab lub thaj chaw ntawm ob khub.

Feem ntau, lub sab sauv ib nrab ntawm cov iav nyob rau hauv cov tsom iav kom koj mus saib nyob deb tej khoom, thiab hauv qab - kom paub qhov txawv tej yam khoom uas nyob ze ntawm. Cov tsom iav tsom iav yuav ua tau ntau dua, ces bifocals yuav ua trifocals los yog txawm multifocal.

Lub tswv yim ntawm creation twb tshwm sim los ntawm qhov, ib co ntau yam ntawm ntses muaj Bifocal pom, uas tso cai rau zoo saib tej yam khoom nyob rau hauv qab ntawm lub reservoir thiab nyob rau tib lub sij hawm zoo ua raws li qhov mus kom ze ntawm cov noog of prey rau saum. Nws yog ntseeg hais tias cov thawj bifocals yees Bendzhamin Franklin, uas ua ke lub ob khub ntawm tsom iav nyob rau hauv ib tug.

Ib tug interesting txoj kev loj hlob ntawm lub tswv yim no tswv yim paub txog ntawm cov neeg Ixayees Zeev Zalewski, uas ua ke rau hauv lub khob kom cov bifocal tsom iav yog yooj yim npaum li siv. Nws tsom iav yog tsis muaj ntse ciam ntawm lub panes. Lub teeb reflected nyob deb deb thiab nyob ze tej yam khoom yog teem nyob rau hauv ib tug tas mus li kwj, uas npog tag nrho cov retina. Qhov no pub rau Attendance zoo rau saib tag nrho cov khoom. Nyob rau hauv cov tsom iav tsawg nkees ob lub qhov muag, thiab yuav tsum tau tsawg lub sij hawm kom hloov mus rau lawv.

nthuav feature twb sau tseg nyob rau hauv lawv tej kev txom nyem. Nws muab tawm hais tias lawv yuav tau kho ob lub visually impaired. Uas yog, cov tsom iav yuav tsis tsuas paub daws tus kab mob no lub hnub nyoog, lawv yog heev pab tau raws li ib tug tiv thaiv kev ntsuas.

Kev loj hlob ntawm siab technologies kuj muab sij hawm ntxiv nyob rau hauv txoj kev loj hlob ntawm qhov teeb meem ntawm kev txuag. Leej twg tsim lub bifocal tsom iav nyob rau hauv nws cov hluav taws xob version. Nyob rau hauv cov ntaub ntawv no, nruab nrab ntawm ob panes yog tso rau hauv ib lub kua siv lead ua screen, uas muab rau peb cov duab.

Nyob rau hauv cov ntaub ntawv ntawm lub tshuab hluav taws xob version ntawm bifocals rau developers muaj kev cov nyom los ua rau kom cov duab zoo. Nthuav khoom tshiab thiab cov kev xaiv los ua rau kom los txo cov duab, thiab kuj autofocus. Tus thawj prototypes yog muab los ntawm PixelOptics, uas nws hais ntxiv hais nws kev tshawb fawb nyob rau hauv cov cheeb tsam no.

Tom qab kev noj kev haus koj tus kws kho mob, koj muaj peev xwm yuav bifocals. Lawv cov nqi txawv nyob ntawm seb lub tuam txhab cov khoom thiab zoo tshaj ntawm cov khoom muag.
