Kunyangwe malenzi akajairwa achikwanisa kusangana nePeople's Daily ziso zvinodiwa, asi nekuwedzera kwenhamba yevanhu vanoona pedyo, zvichienderana nemamiriro akasiyana ekushandisa, vagadziri velens vakagadzira malenzi anoshanda ayo anowanzo shandiswa.
Semuyenzaniso, anti-blue lenses enharembozha nemakomputa, discoloration lenses ekunze kwezuva muchirimo, malenzi ekutyaira husiku ekugara achityaira husiku, uye malenzi anofambira mberi kune vanhu chaivo...
Chii chinonzi ainofambira mberi multifocal lens?
Chaizvoizvo, zvinogona kuzivikanwa kuti imhando yelenzi inoumbwa neakawanda anotarisisa mapoinzi uye akasiyana madhigirii.
Kazhinji, kune nzvimbo ina: nzvimbo iri kure, iri pedyo, nzvimbo inofambira mberi, yekuruboshwe nekurudyi deformation nzvimbo (inonziwo peripheral area kana fuzzy area).
Iyo lenzi ine isingaonekwe imprint uye inotungamira imprint ~
Progressive lenziakakodzera vanhu
Mubasa chairo, maitiro ekutonga kana munhu akakodzera kupfeka lenzi anofambira mberi anoda kutariswa zvinoenderana nezvinodiwa nevatengi.Mushure mekuona kana vatengi vakakodzera huwandu hwevanhu, vashandi vedu vanofanirwa kuita chaiyo optometry pavari kuona kuti vane mvumo yakakodzera yemagirazi.
Zviratidzo zvema lenzi anofambira mberi
1. Zvakaoma kuona pedyo, saka magirazi ekuverenga anodiwa, achitarisira kudzivisa dambudziko rinokonzerwa nekutsiviwa kwemagirazi nekuda kwevanhu vanoona kure.
2. Vanopfeka vasingagutsikani nechitarisiko chebifocals kana triocals.
3. Vanhu vane makore ekuma40 nema50 vachangopinda muchikamu che "presbyopia".
4. Tarisa kure uye pedyo nevanhu vanochinjana kazhinji: vadzidzisi, vatauri, vatungamiri.
5. Vatauriri vevoruzhinji (semuenzaniso, vatungamiri vehurumende vanopfeka lenses inofambira mberi).
Contraindications yema lenzi anofambira mberi
1. Nguva yakareba yekuona vashandi vepedyo: vakadai sekombuta yakawandisa, pendandi, vanodhirowa vagadziri, madhizaini edhizaini;
2. Basa rinokosha: sevanachiremba vemazino, vashandi veraibhurari, (nekuda kwehukama hwekushanda, kazhinji vanoshandisa pamusoro pe lens kuti vaone pedyo) vatyairi vezvikepe, vafambisi vezvikepe (shandisa pamusoro pelens kuona pedyo) kana kushandisa mucheto wepamusoro iyo lens yekuona iyo inotarirwa huwandu hwevanhu, kufamba kwakanyanya, kurovedza muviri;
3. Varwere vane anisometropia: maziso ose ane anisometropia> 2.00D, anobudirira column degree> 2.00D, kunyanya axial asymmetry;
4.ADD kupfuura 2.50D (" pedyo nekushandisa + 2.50d ", zvichiratidza kuti maziso akagadzira presbyopia, unoda kuwedzera magirazi ekuverenga 250 degrees.);
5. Kupfuura makore makumi matanhatu (zvichienderana nehutano hwehutano);
6. Avo vanowanzopfeka chiedza chakapetwa kaviri kare (nekuda kwenzvimbo yakafara iri pedyo nekushandiswa kwechiedza chechipiri uye yakamanikana pedyo nekushandiswa kwegirazi rinofambira mberi, pachava nekusagadziriswa);
7. Vamwe varwere vane zvirwere zvemaziso (glaucoma, cataract), strabismus, dhigirii yakanyanyisa haifaniri kupfeka;
8. Chirwere chekufamba: chinoreva kusanganiswa kwedzungu uye chizuru chinokonzerwa nekushaya kuenzana kwebasa mukukurumidza kuzvimiririra kana kufamba-famba, zvakadai sechirwere chekufamba, gungwa, nezvimwewo;Mukuwedzera, varwere vane hypertension uye arteriosclerosis, kana chirwere chavo chisina kunyatsogadziriswa, chinowanzoonekwa nekuda kwekusakwana kweropa recerebrovascular kunokonzerwa nedzungu, dzimwe nguva kunogona kukonzera vasospasm, uye musoro;
9. Vanhu vane dambudziko rekugadzirisa magirazi;
Kiyi yekutima lenzi anofambira mberi: Yakarurama Optometry
Kuona zviri pedyo hakuna kudzika, uye kuona zviri mberi kwakadzama.
Nekuda kwehunyanzvi hwekufambira mberi kwemultifocal lens kana ichienzaniswa ne-single-light lens, inofambira mberi multifocal lens haifanire kungogutsa chiono chakanaka munzvimbo yechiedza chiri kure, asi zvakare funga nezve mhedzisiro chaiyo munzvimbo yepedyo yechiedza kuita iyo inofambira mberi lens. akasununguka kupfeka.
Panguva ino, "kureba kwechiedza" kunofanira kubva pakushandiswa kwakanaka kwechiedza chepedyo, saka myopia luminosity yechiedza chakareba haifaniri kunge "yakadzika", nepo myopia luminosity yechiedza chiri kure haifaniri "kunyanya kudzika" , kana zvisina kudaro iyo "yakakura kwazvo" yeADD ichaita kuti kunyaradza kwe lens kuderera.
Pamusoro pekuona kuti chiono chekure-chiedza chakajeka uye chakasununguka mukati mehutano chaihwo hwekushandiswa, chiedza chiri kure-chinofambira mberi chinofanira kunge chisina kudzika uye chiedza chekuona kure chinofanira kunge chakadzika uye chakadzika.
Kusarudzwa uye kugadzirisa kwelenzi inofambira mberimafuremu
Progressive yakawanda-yakatarisana yakakosha pakusarudza iyo chaiyo furemu uye kugadzirisa.Yakanyanya kutarisisa inofanirwa kupihwa kune anotevera pfungwa:
Kugadzikana kweframe yakanaka, inoenderana nechimiro chechiso chemutengi, kazhinji haifanire kusarudza deformation iri nyore yefuremu isina furemu, kuve nechokwadi chekuti kumberi kwakakomberedzwa curvature yefuremu uye curvature yeanopfeka inopindirana.
Iyo furemu inofanira kuva nehupamhi hwepamusoro hwakakwana, iyo inofanira kusarudzwa maererano nemhando ye lens yakasarudzwa.Zvikasadaro, zviri nyore kucheka chikamu chiri pedyo chekuona paunenge uchicheka kumucheto:
Nzvimbo yepakati yemhino ye lens ichave yakakwana kugadzirisa nzvimbo ye gradient;Ray-ban furemu nemamwe mafuremu ane kurerekera kukuru kuzasi kwemukati memhino pedyo nemunda wekuona idiki pane general frame, saka haikodzere zvishoma nezvishoma girazi.
Ziso kureba kweframe lens (kureba pakati peiyo posterior vertex ye lens uye anterior vertex ye cornea, inonziwo vertex kureba) inofanira kuva shoma sezvinobvira pasina kubata eyelashes.
Gadzirisa Angle yekumberi yefuremu zvinoenderana nechiso chemupfeki (mushure mekunge furemu yaiswa, mharadzano Angle pakati pendege uye ndege yakamira yerin'i yegirazi inowanzoita 10-15 madhigirii, kana dhigirii rakakura kwazvo, iyo yepamberi Angle inogona kugadziridzwa kuti ive yakakura), kuitira kuti ienderane nefuremu nechiso zvakanyanya sezvinobvira, kuitira kubatsira kuchengetedza zvakakwana zvishoma nezvishoma nzvimbo yekuona.
