Bifocal lenses inyanzvi yegirazi lenses akagadzirirwa kusangana nezvinodiwa zvinoonekwa zvevanhu vanonetsekana kutarisa pazvinhu zviri pedyo uye zviri kure.Aya anotevera ndiwo mapoinzi akakosha ekutarisisa kana uchikurukura nezve kushandiswa kwema bifocal lenses:
Presbyopia kugadziriswa:Bifocal lenses anonyanya kushandiswa kugadzirisa presbyopia, chikanganiso chine chekuita nezera chinokanganisa kugona kweziso kutarisa pazvinhu zviri pedyo.Mamiriro acho anowanzoonekwa akapoteredza makore makumi mana uye anokonzera kuoma kuverenga, kushandisa zvigadzirwa zvemadhijitari uye kuita mamwe mabasa epedyo.
Kugadziriswa kwekuona kaviri:Bifocal lenzi ane maviri akasiyana masimba ekuona mune imwe lenzi.Chikamu chepamusoro chelenzi chakanyatsogadzirirwa kugadzirisa chiono chemufambo, nepo chikamu chezasi chine diopta yekuwedzera yekuona pedyo.Iyi mishonga miviri inobvumira varwere vepresbyopic kuti vave nepeya yemagirazi kuti vasangane nezvavanoda pazvinhambwe zvakasiyana.
Seamless shanduko:Dhizaini ye bifocal lenses inobvumira shanduko isina musono pakati pepamusoro nepasi zvikamu zve lens.Iyi shanduko yakatsetseka yakakosha kune yakagadzika uye inoshanda yekuona chiitiko kana uchichinja pakati pezviitwa zvinoda kuona pedyo uye kure.
Zviri nyore uye zvakasiyana-siyana:Bifocal lenses inopa kurerukirwa uye kuita zvakasiyana-siyana kune vanhu vane presbyopia nekupa mhinduro yekuona kwepedyo uye kure mupeya imwe yemagirazi.Panzvimbo pekugara vachichinjana pakati pemagirazi akawanda, vashandisi vanogona kuvimba nebifocals kune akasiyana emabasa uye zviitiko, sekuverenga, kutyaira, basa rekombuta, uye zvinokuvaraidza zvinosanganisira kuona pedyo kana kure.
Kushandiswa pabasa:Bifocal lenses anowanzo kukodzera kune vanhu vane mabasa kana zviitiko zvezuva nezuva zvinoda kuchinja kazhinji pakati pepedyo nedaro.Izvi zvinosanganisira mabasa akadai sevatapi vehutano, vadzidzisi, makanika, uye maartist, uko kujeka kwakajeka pamatanho akasiyana kwakakosha kuita kwakaringana uye kuchengetedzeka.
Kugadziriswa kwezvido zvemunhu: Bifocal lenses inogona kugadzirwa kuti isangane nezvinodiwa nemunhu wega wega.Optometrists uye ophthalmologists vanonyatso ongorora zvinodiwa nemurwere zvekuona uye mararamiro kuti vatarise akanyatsokodzera bifocal lens dhizaini, vachiona kuti kunyorerwa kunoenderana nezvinodiwa zvebasa ravo uye zviitwa zvekutandara.
Zvishoma nezvishoma gadzirisa kune:Kune vatsva vanopfeka lens bifocal, pane nguva yekugadzirisa kuti maziso agadzirise kune bifocal lenzi.Varwere vanogona kutanga vasangana nezvipingamupinyi kugadziridza kune dzakasiyana nzvimbo dzekutarisa mukati me lens, asi nekufamba kwenguva uye nekudzidzira, vanhu vazhinji vanojairana nemazvo uye vanonakidzwa nemabhenefiti ekuvandudzwa kwekuona uye kure.
Mukupedzisa, bifocal lenses yakakosha kugadzirisa yakasarudzika yekuona matambudziko anounzwa nepresbyopia.Dhizaini yavo yezvinyorwa zviviri, shanduko isina musono, nyore, kuita zvinhu zvakasiyana-siyana, uye kugona kugadzirisa kunoita kuti ive mhinduro yakanakira vanhu vari kutsvaga yakajeka uye yakagadzika chiono pamadaro akasiyana muhupenyu hwavo hwezuva nezuva.
Ndiani anofanira kupfeka bifocals?
Magirazi eBifocal anowanzo kunyorerwa vanhu vane presbyopia, mamiriro ane zera anokanganisa kugona kweziso kutarisisa zvinhu zviri pedyo nekuda kwekurasikirwa kwechisikigo kwekunaka mulenzi yeziso.Presbyopia inowanzoonekwa muvanhu vanopfuura makore makumi mana, zvichikonzera kuomerwa nekuverenga, kushandisa michina yedhijitari, uye kuita mamwe mabasa ari pedyo.Mukuwedzera kune presbyopia inoenderana nezera, magirazi ebifocal anogonawo kukurudzirwa kune vanhu vanotarisana nedaro uye pedyo nematambudziko ekuona nekuda kwezvimwe zvikanganiso zvekufungidzira zvakadai sekuona kure kana myopia.Naizvozvo, bifocal magirazi anopa mhinduro iri nyore kune vanhu vanoda akasiyana masimba ekuona kuti asangane nezvinodiwa zvekuona kwavo kure kure.
Ndeipi nguva yaunofanira kupfeka bifocals?
Magirazi eBifocal anowanzo kukurudzirwa kune vanhu vane dambudziko rekuona zvinhu zvepedyo nekuda kwepresbyopia, kukwegura kwepanyama kunokanganisa kukwanisa kwemaziso kutarisa pazvinhu zviri pedyo.Mamiriro acho anowanzoonekwa akapoteredza makore makumi mana uye anowedzera nekufamba kwenguva.Presbyopia inogona kukonzera zviratidzo zvakadai sekunetseka kweziso, kutemwa nemusoro, kusaona uye kuomerwa nekuverenga zvinyorwa zvidiki.Magirazi eBifocal anogonawo kubatsira vanhu vane zvimwe zvikanganiso zvekuona, sekuona pedyo kana kuona zviri kure, uye vanoda masimba ekuona akasiyana ekuona zviri pedyo uye kure.Kana iwe ukaona kuti iwe kazhinji uri chinhambwe kubva pakuverenga zvinhu, kuona kuomerwa kweziso paunenge uchiverenga kana kushandisa michina yedhijitari, kana uchida kubvisa magirazi ako kuti uone zvinhu zviri padhuze, ingave nguva yekufunga nezve bifocals.Pamusoro pezvo, kana iwe uchitopfeka magirazi ekuona chinhambwe asi uchizviwana uchinetseka nemabasa ari padyo, bifocals inogona kupa mhinduro iri nyore.Pakupedzisira, kana uine dambudziko nekuona pedyo kana kuwana zvakaoma kuchinja pakati pemagirazi akawanda ezviitwa zvakasiyana, kukurukura bifocals nenyanzvi yekuchengeta maziso kunogona kubatsira kuona kana iri sarudzo yakarurama yezvido zvako zvekuona.
Ndeupi musiyano uripo pakati pebifocals uye lenses dzenguva dzose?
Bifocals uye lenzi dzakajairwa ese ari maviri marudzi emagirazi emaziso anoshanda zvinangwa zvakasiyana uye anosangana nezvinodiwa zvekuona zvakasiyana.Kunzwisisa mutsauko uripo pakati peaya marudzi maviri emalenzi anogona kubatsira vanhu kuita sarudzo dzine ruzivo nezvesarudzo dzekugadzirisa maonero.
Malenzi akajairika: Malenzi enguva dzose, anonziwo single vision lenzi, akagadzirwa kuti agadzirise chimwe chikanganiso chekutarisa, sekuona pedyo, kuona kure, kana astigmatism.Malenzi aya ane simba rinoenderana nerakanyorwa pamusoro pese pese uye anowanzo gadzirwa kuti ape kuona kwakajeka pachinhambwe chimwe chete, kungave pedyo, pakati, kana chinhambwe.Vanhu vanoona zviri pedyo vanogona kubatsirwa nemalenzi emishonga anovabvumira kuona zvinhu zviri kure zvakajeka, nepo vanhu vanoona zviri kure vangada malenzi kuti vavandudze kuona kwavo pedyo.Pamusoro pezvo, vanhu vane astigmatism vanoda lenzi kuti vatsivise kupetwa kwecornea kana lens yeziso, zvichivabvumira kuti vatarise mwenje nenzira kwayo paretina.
Bifocal lenses: Bifocal lenses akasiyana nekuti ane maviri akasiyana masimba ekuona mukati meimwe lenzi.Malenzi akagadzirirwa kugadzirisa presbyopia, mamiriro ane zera anokanganisa kugona kweziso kutarisa pazvinhu zviri pedyo.Sezvo isu tichikura, lenzi yepanyama yeziso inova isingachinjiki, zvichiita kuti zviome kutarisa pamabasa ari padyo sekuverenga, kushandisa smartphone, kana kuita basa rakadzama.Dhizaini ye bifocal lenses inosanganisira mutsara unooneka unoparadzanisa kumusoro uye pasi zvikamu zve lens.Chikamu chepamusoro chelens chinowanzo shandiswa kuona chinhambwe, nepo chikamu chepasi chine simba rakasiyana rekuona rekuona.Iyi dhizaini-yemasimba maviri inobvumira vanopfeka kuti vaone zvakajeka pamadaro akasiyana pasina kuchinja pakati pemagirazi akawanda.Bifocal lenses inopa mhinduro iri nyore uye inoshanda kune vanhu vanoda kururamiswa kwekuona kune ese ari pedyo uye kure kure.
Misiyano mikuru: Musiyano mukuru pakati pebifocal lenzi uye akajairwa lenzi magadzirirwo awo uye chinangwa chekushandiswa.Malenzi enguva dzose anogadzirisa zvikanganiso zvakati refractive uye anopa kuona kwakajeka pachinhambwe chimwe chete, nepo bifocal lenzi dzakagadzirirwa kugarisa presbyopia uye kupa biphoto kururamisa kune pedyo uye kure kuona.Malenzi enguva dzose anoshandiswa kururamisa kuona zviri pedyo, kuona kure, uye astigmatism, nepo bifocal lenzi inopa kuona kwakajeka pamadaro akawanda nekubatanidza masimba maviri emishonga mulenzi imwe chete.Muchidimbu, malenzi enguva dzose anobata kune chakakanganisika chikanganiso uye anopa kururamisa kwechiratidzo chimwe chete, nepo bifocal lenzi dzakagadzirirwa kugadzirisa presbyopia uye nekupa mhinduro yebifocal yekuona pedyo uye kure.Kunzwisisa mutsauko uripo pakati peaya marudzi maviri emalenzi kunogona kubatsira vanhu kuti vasarudze yakanyatsokodzera gadziriso sarudzo zvichienderana nezvavanoda uye zvavanofarira.
