Hyperopia - yiloo lokwengeza okanye lokucutha? Ezibangela hyperopia. ezikude yobudala

Sidla ukuva imibuzo abantu alunalwazi luphangaleleyo hyperopia - ke dibanisa okanye thabatha. Ukuze uphendule ngokuchanekileyo imibuzo enjalo, kubalulekile ukuqonda kumthetho imizimba komntu bahlole iingxaki kunokwenzeka ezivelayo.

Eye - le yenye amalungu ezininzi ezimbaxa emzimbeni womntu. Ukusebenzisana kwenkqubo olubonakalayo ukuya neuron ikuvumela ukuba ukuguqula imitha yokukhanya evela ehlabathini lwangaphandle ibe imifanekiso ebonwayo. Ukuze uqonde kwenzeka njani oku, kufuneka siqwalasele oko emehlweni oluntu.

Indlela emayenziwe ngayo iliso

Iliso sisixokelelwano enombala entsonkothileyo kakhulu entlantlu ungamalungu amaninzi.

1. Inwebu. Ngawo, amaza okukhanya ufake iliso. Oku kubonisa se ephilayo ngayo ingqalelo kumacala eziphambukileyo ye imiyalezo ukukhanya.
2. Sclera - engaphandle esingxotyeni iliso ngaphaya kwawo, nto leyo athathe inxaxheba ekuqhubeni ukukhanya.
3. Iris - into efana camera beso. Le nxalenye lilawula ukuhamba kwamasuntswana ukukhanya wenza umsebenzi ubuhle, nokumisela umbala iliso yabantu.
4. Umfundi - umngxuma kwi iris olawula imali reyi ukukhanya nghena iliso, kwaye ukhula umile agqwetha ray.
5. Lens - amandla lensi yesibini emzimbeni womntu, ebekwe ngoko nangoko emva iris. Kuxhomekeka umgama ukuya into itshintsha ngamandla alo okubonakalayo. E kumgama omncinane kwandisa ngokubanzi - buthathaka.
6. Retina - ubuso ungqukuva, nto leyo kuthelekelelwe kwi ihlabathi ngaphandle. Ngaphezu koko, ukukhanya acandacanda ilens ezimbini esihlanganyelweyo, iwela retina ngohlobo zocaphulo. Le nkcazelo ithotyiweyo aze ke atshintshelwe ube amaza elektroniki.
7. Macula - umbindi retina, neqaphela umfanekiso umbala ecacileyo.
8. luvo Umthambo - yokuthutha kusingathwa retina ube amaza luvo kulwazi zobuchopho.

Types of iingxaki mbono

iingxaki Umbono zisenokuvela nanini na ubudala ngokupheleleyo (zinokude naso). Unobangela abanye babo - yaphula retina okanye umsebenzi luvo optic. Noko ke, uninzi izifo inkqubo olubonakalayo Bamqumbisa ukugxojwa iimpawu zokunganyangeki iso. Le nokulandelelana defocusing, kwaye umntu ulahlekelwa ubuchule ukuze ubone ngokucacileyo izinto. Oko kuphazanyiswa mbono zabantu. "Plus 'yaye' thabatha 'kulo mzekelo jonga iqondo refraction sokukhanya (okanye imitha hayi ngokwaneleyo refracted okanye refracted njengoko kakhulu). Kukho iindidi eziliqela ezisisiseko ongaboniyo ebantwini.

Ukubona - oku elifutshane bisayo

Xa umntu ukubona akaboni izinto ezikude. Kufuphi amehlo yesiqhelo. Kulo sifo, ungakwazi lula ukufunda incwadi, kodwa ke inani le ndlu, ibekwe ngaphaya kwendlela, sinako kakade.

Kude-bisayo - i "dibanisa" okanye "thabatha '?

Makhe siye umva kumbuzo engundoqo. Ngoko ke, kude-bisayo - i "dibanisa" okanye "thabatha '? Ezikude (hyperopia oko) - oko ukungaboni, apho umntu embi ukwahlula izinto ezikufuphi, kodwa ngokugqibeleleyo ukwahlula iinkcukacha ngokupheleleyo izinto ezikude.

Ngenxa yoko, iingongoma amandla, amayeza isigulane ulinganiswa diopters. Nge hyperopia wabeka iglasi kunye nempembelelo ukuqokelela, nto leyo yenza inxalenye kwemisebenzi lens. Le window ibizwa ngokuba HIV, kwaye ukuza kuthi ga ngoku-bisayo - i "dibanisa." Okanye "negative" umzekelo, isetyenziselwa elifutshane-bisayo. Ngoko ke, unyango yeglasi babesebenzisa nefuthe nokuphalazeka kwelifu, leyo kuthiwa negative.

Presbyopia - ntoni na?

Ezikude yobudala kwindawo yonyango kuthiwa presbyopia, kwaye ubukhulu becala zifumaneka kubantu kwiminyaka engama-40. Esi sifo sibangelwa ngokulahlekelwa luthambe lens kwaye sibonakaliswa kukufelwa ukukwazi ukutshintsha ingqwalasela xa translation amehlo ujonge izinto abakwiindawo ezikude ezahlukeneyo.

astigmatism

Out umbono zithwala astigmatism kuvela ngenxa yeenguqu esime lens kwaye sibonakaliswa kwi refraction oluchanekileyo reyi ukukhanya. Kuthi zonakaliswa ngenxa kulo mfanekiso yehlabathi ngaphandle.

Yintoni unobangela cataract?

A cataract sisifo eqhelekileyo kakhulu, obuquka ongaboniyo. Kaninzi kwenzeka iminyaka abadala, kodwa kuba sisiphumo sisifo wentsholongwane egazini. A ukubonakalalisa esi sifo a clouding lens.

I Siphakamisa kweli nqaku ukuqwalasela kwimiba ezinye iinkcukacha ezinxulumene oko ezikude.

Eyona eziphambili ezibangela hyperopia

Ngoko ke, njengoko sele kubonisiwe, ukubona kude - sisifo amehlo apho umfanekiso swi emva kwiretina. Uphuhliso hyperopia iliso lixhomekeke ukukwazi refract imitha yokukhanya okuvela yokuhlala (iimpawu lens ukutshintsha imilo yayo ngokuxhomekeke umgama ukuya into):

1. Buthathaka (diopters kwi-phinde ngo 2).
2. Umyinge (ukusuka diopters-phinde ngo 2 ukuya +5).
3. A strong (ngaphezulu kwe +5 diopters).

Kukho izizathu ezimbini hyperopia:

1. Too yeso elifutshane, kwaye, ngenxa yoko, elifutshane axis longitudinal kweliso. Amaninzi, le sifo umbono ilifa.
2. Iipropati Ukunqongophala zokunganyangeki kwinkqubo olubonakalayo. Nge ubudala, ilens crystalline uphelelwa luthambe nobuchule efanelekileyo.

Kukho kwakhona okuba yomthonyama ethi idibanise ezi zizathu zibini.

iimpawu hyperopia

Uphawu eziphambili umbono ihlwempu ezikufutshane. Kulo mzekelo, izinto ezikude, isigulane ubona kakuhle. Noko ke, ekuhambeni kwexesha ngezifo kwengeniso ngenxa yokulahleka iipropati lens accommodative.

Iimpawu eziphambili, ubukho leyo ekhokelela dibana liyincutshe iliso kunye hyperopia kukrokrelwa, ziquka:

1. Ukophulwa yemboniselo "kufutshane".
2. Ukophulwa i "kude" buka.
3. Ukwanda fatigue iliso xa besebenza.
4. fatigue Visual xa efunda.
5. conjunctivitis rhoqo kunye nezinye iinkqubo arhabaxa iliso.
6. Strabismus ebantwaneni.

Uxilongo abanengxaki nokubona

Kamsinya nje uziva ukuhla acuity ezibonwayo, kufuneka ucele uncedo lobungcali. inkqubo Standard zokuxilonga kubandakanya le manyathelo alandelayo:

1. acuteness zokufunda. Ukulungiselela le njongo, kukho ekhethekileyo itafile view. esetyenziswa ngoku itheyibhile Sivtseva Golovin okanye Orlova (ingakumbi abantwana).
2. Uphando lo fundus ngokusebenzisa esipilini, ultrasound.

3. Ukukhethwa ngelensi amandla olugcinwe yi a phoropter.

ukuphathwa hyperopia

iingxaki umbono Ukwenza anizanga azidube kufuneka kusekelwe phezu kwezi zimiselo zilandelayo:

1. Gcina imo izibane.
2. emzimbeni nokudubula umthwalo olubonakalayo enye.
3. Qeqesha izihlunu ezibonwayo ukusebenzisa imisebenzi ekhethekileyo amehlo kangakanani na, yaye kunye nokusetyenziswa ubuchwepheshe bale mihla (kubandakanywa ikhompyutha kunye laser).
4. Ukufunyaniswa kwangoko kunye nokulungiswa umbono ezichanekileyo (kuquka umyalelo zamehlo zohlolo ngamaxesha athile).
5. Yenza umthambo okubuyisela, exhaswa yi ekunene-yayigcina.

Ukuphunyezwa kwezi amanyathelo othintelo uya kuwulondoloza umbono. Plus, Kakade ke, musa ukulibala ukuba bapase iimviwo ngamaxesha yi zamehlo.

ulungiso Umbono lwenziwa ngoncedo iindondo zamehlo okanye lenses, leyo zikhutshelwa kwi njengesigulana iresiphi okhethekileyo, emva kokuba uphando olupheleleyo.

Ukongeza, utyando amehlo uya imitsi phambili kwaye ngoku ivumela umntu ayeke ndisazibuza loo mbuzo, ukubona kude - i "dibanisa" okanye "thabatha".
