Ezigquma diopters: inkcazelo, iintlobo, models kunye nohlolo

Nokufika kwehlobo, xa umsebenzi elanga ifikelela imbuyekezo ubuninzi ubushushu nokukhanya namandla, ophthalmologists basoloko ukukhumbuza izigulane zam ukuba kuphela ukukhusela amehlo akho ukusuka ukukhanya, kodwa ukugcina ukubonakala elungileyo, leyo zilungiswe ngendlela eqhelekileyo - encediswa diopters.

Not ekhuselweyo elangeni ngqo kunye nomsebenzi eliphezulu amandla ukukhanya, amehlo abakhuselekanga phantse burns efanayo ukukhanya, kwakunye esikhumbeni. Elanga, isenza buthathaka kakhulu wobhobhozayo ukukhanya ukukhusela iimpahla Umthambo-luvo, isifo kunye negazi, leyo ifana ukuzikhusela ukukhanya kwelanga eliqaqambileyo. Abantu abaye ababenengxaki acuity ezibonwayo, ubuso ukhetho: ukulondoloza nokukhusela amehlo okanye aboniswe ingozi kunye nokusebenzisa iindondo eziqhelekileyo kunye diopters.

Iingongoma for ukhuseleko ilanga kunye diopters

Ngenxa amathuba zakutshanje zobugcisa ingxaki yokudibanisa iindondo aqhelekileyo ngokulungiswa mbono ukusombulula ngokupheleleyo. Phantse eklinikhi okanye impilo yonke ziko, nto leyo ngokorhwebo ezikhoyo ngokukhanya, ungathenga ezigquma diopters. Baya kuya kusikhusela imitha yelanga eyingozi, kwaye acuity olubonakalayo uhlala kwinqanaba elifanelekileyo. Ukuze uthenge imveliso enjalo kakhulu kwiindawo ezikhethekileyo zentengiso. Ku khongela kwimarike akuqinisekisi umgangatho iimpahla, yaye oko kuyingozi kwimpilo iliso.

On ezigquma amaxabiso diopters zinokwahluka. Konke kuxhomekeke umgangatho weemveliso, umenzi (eyaziwa okanye uhlobo ayaziwa) kunye nezinye iimpawu. Iindleko iimodeli ezininzi isiphelo ephantsi-, nge-avareji uvela engange 600 ukuya 1500. Kodwa ngaphambi kokuba uthenge imveliso, kufuneka kuqala kuvavanywa yi yincutshe.

Iinzuzo kwelanga Optics kunye diopters

Ixesha lubonise ukuba izigulane ezininzi usebenzisa ezigquma diopters, uyakholiswa kakhulu ngokufumana. Ukuze ubone ngokucacileyo izinto nokukhusela ngaloo ngokupheleleyo amehlo akho elangeni ngqo ukusombulula ingxaki yokuphumla elungileyo kunye nomsebenzi kwiindawo ezivulekileyo. Abavelisi bakwazi diversify eziveliswa kolu didi, kwaye namhlanje unazo iinketho zilandelayo izibuko ne-hlengiso:

• Ezigquma diopters abaqhubi.
• Iimfaniso for ukuqubha.
• Iimfaniso ngemidlalo.
• Iiglasi abantwana.
• Ezigquma diopters emsebenzini kunye nolonwabo.

Kubaluleke kakhulu ukuba ezinye iimodeli ukwenza nje umsebenzi wabo zokuzikhusela ngqo, kodwa kwangaxeshanye igcine acuity ebonwayo ezinqwenelekayo.

ukhethe Iimpawu

Uxilongo kumaziko kuya kukunceda ukuba ukhethe imodeli elungileyo. Kuyimfuneko ukuba ukukhumbula ukuba ezigquma diopters ingahluka iimpawu ezithile kwiinkalo. Umzekelo, izibuko nolovane kwi iiglasi eqaqambileyo ukutshintsha umbala okhanyayo, yabangazijongisisi ngokulitywina, ngokwenjenjalo ngokulungelanisa imeko ngokuzenzekelayo umgangatho wokhuseleko lweliso lakho. Xa ngokukhanya ekukhanyeni low kwakhona kube selubala, ngaloo ndlela evumela ukwandisa ukuqukuqela ukukhanya iris ze iliso, nto leyo ethintela overvoltage Umthambo-luvo.

Umbandela ezininzi esisiseko lokufunyaniswa inkcazelo acuity olubonakalayo. Ngokusekelwe kwiziphumo, khetha i yokukhanya ekunene. Eyona nto ibalulekileyo kakhulu: Amehlo akho asekhohlo nasekunene babe ezahlukeneyo parameters, kulo mzekelo, ilens kunye diopters ilungelo odwa ngabanye.

okubonakalayo iparameters ekufuneka ukuba zithathelwe ingqalelo

Enoba kunjalo, phambi kokuba uthenge ezigquma diopters, kuyimfuneko ukuba banikele ingqalelo ezi ngongoma zilandelayo:

• Umenzi. I odumileyo ngakumbi ngumvelisi, ayanda umgangatho lens ezinamanqwanqwa.
• Ukuba isikolo kufuneka sinyanzeliswe ukuzama ukuvavanya model ecetywayo.
• Anti-ibonisa enamathela phezu lens, leyo sisigcina iphambili ngokuchasene ngokuhlaselwa yelanga eyingozi kwi retina, kuyimfuneko ukuba imifuziselo ezinjalo.

Bad Umaleko ngeso lenyama okanye ukungabikho kwayo nje loo ipatheni ezingacacanga ungapheleli kulahleka imibala ibonisa libya.

Glass okanye iplastiki

Inyaniso ukuba iilensi yeplastiki ixesha elide lokukhuphisana umgangatho ngeglasi, waziwa kakuhle. Uncedo wethu ke amathuba seplastikhi esitransparenti ekusebenzeni ukumelana zizothuso koomatshini - ukuba kunzima ukwahlukana. Kodwa kukho nobubi, oko ukuba umenzi olu hlobo ngokukhanya akuthethi isaziso.

• Ngexesha ukusebenza, lo yeplastiki igutyungelwe iintanda ezincinane, imikrwelo.
• Ekuhambeni kwexesha, komhlaba izibonelelo likhubazeke kunye namafu.
• Nangona isihlobo zeplastiki zamaxabiso aphantsi, ezikumgangatho ophezulu ukulungiselela umsebenzi babephila elifutshane.

Kuba intengiso luphawu elungileyo ngokukhanya, eyenziwe ngeplastiki, engaquki kugxagxiseka ixesha elide yaye akafuni bayasigqwetha umfanekiso, kodwa umthetho, ezi mveliso zenziwa umenzi eyaziwa kuphela neendleko imali.

lens Glass ngu umgangatho yokuvelisa imifuziselo zeplastiki eziphezulu kakhulu. Kakuhle iglasi ejolise edlulisela umfanekiso kwi retina 1: 1, lo mbandela ungcono engundoqo.

Bobubi lens zeglasi ekunokuthiwa kuphela iingongoma ezimbini:

• Umonakalo owenziwe umothuko ngoomatshini.
• Ipesenti ephezulu fogging emva utshintsho ngokukhawuleza kwindawo ukusuka abandayo enye efudumeleyo.

Ophthalmologists, ngokucebisa izigulane zabo, kukhethwa lens iglasi, njengoko ngcono.

izibuko

okokuqala zonke Xa ukhetha isakhelo, sinikela ingqalelo kuyilo kunye nesimbo. Ukongeza, xa ukhetha isakhelo kufuneka balujongisise ngenyameko material yenziwe kuzo. Isakhelo kufuneka ungazithambisi kwaye cinezela, kubangele ubuhlungu ulusu, apho kukho ukudibana rhoqo. Onobuhle iitempile rubberized kunye abicah septa kakuhle ukholosile ukuhlala ibhulorho empumlweni, ngaphandle ebangela ukukruquka kunye umonakalo nolusu.

zamehlo madoda diopters

Design izakhelo ngokukhanya yahlulwe ngokwendidi ezintathu. Ngoko ke, omnye imixholo ithandwayo abenzi ezi iindondo amadoda kunye diopters, ezo umncedisi onyanisekileyo, hayi nje kuphela kweli khaya, kodwa kwakhona emsebenzini. A Inani imisebenzi oyindoda kuquka abasebenza ngaphandle elangeni, apha abakhi, pavers indlela, abaqhubi, amafama kunye nabanye. Abaninzi kubo iingxaki mbono, ngoko amehlo zabo adinga ukhuseleko ekhethekileyo. Ngeteknoloji entsha ithuba lokusebenzisa kwamagqabi ilanga phezu iindondo umbono ngoxa uqhuba, ngexesha lokuphumla ngexesha umthambo.

Xa wokutshiza iilensi usebenzisa amanqanaba ahlukeneyo izikhanyisi ezinoxinwano ezahlukeneyo kunye nesakhono Kwathi imitha yelanga kwi retina. Kukho ukutyabeka layer 4:

• "0" - 20% yenqanaba lokhuselo ukusuka elangeni. Scope - amagumbi ofisi kunye nendawo kunye kwelanga encinane okanye non-abasisigxina.
• "1" kunye "2" - lobeko ezifanekileyo ukusetyenziswa ekhaya. Ukukhuselwa amehlo ukusuka elangeni phakathi-20 nama-80%.
• "3" - ubuncinane 90% wokhuseleko esweni imitha yelanga. Eyona ndlela ilungileyo wayesaziphumlele elunxwemeni.
• "4" - inqanaba inamandla wokhuseleko esetyenziswa yi climbers abaqeqeshiweyo kunye nabakhenkethi kumazwe eliphezulu umsebenzi elanga.

izinto Photochromic, apho kusetyenziswa ekuhlawuleni ilens - le yenye lwezona zamvanje kwihlabathi lwezenzululwazi, apho wagqiba ingxaki wokhuseleko esweni ilitha kunye imitha yelanga kunye nokulungiswa olongezelelweyo malunga nombono ibuyele kwisiqhelo kubantu abane ongaboniyo.
