Astigmatism: Unyango ixhomekeke ebukhulwini

Abanye abantu babone ihlabathi kancinane eyohlukileyo kakhulu. Ngamanye amaxesha isizathu soku - astigmatism. Yintoni isizathu i "tsibayo zehlabathi" enjalo? Inyaniso yokuba i inwebu kubantu unesifo onjalo azilingani. Ngokwesiqhelo, le shell ngaphaya kunceda ukujolisa imitha kwi retina. Xa izigulane astigmatism ngenxa imilo mgaqweni le inwebu akuthethi ukuba ubone umfanekiso ocacileyo.

Yintoni ekwenyukeni ukwenzeka imeko efana astigmatism? Izizathu azikho iyunifomu. Ingaba yesifo awazalwa enaso, oko kuyenzeka, oku kwenzeka emva kokuba eye ukwenzakala (yimikrwelo okanye amaqhuma) okanye usuleleko yangaphambili. Ngamanye amaxesha into yokuba umntu Neenkophe enzima kakhulu. Abanesidanga ezibuthathaka astigmatism kunceda ukuqhwanyazaemva elula, ngoko umbono ayikho kakuhle kunye namanyathelo athathiweyo yokuzikhethela. Kwiimeko ezininzi kakhulu zifuna ukulungiswa umbono.

Indlela ukuxilonga astigmatism? Iimpawu kungenzeka ukuba ingacaci, ezifana ukungaboni, ngoko isicelo iimvavanyo ezithile ngoxilongo.

Okokuqala, usebenzisa itafile rhoqo ukumisela acuity ezibonwayo, nangona, Kakade ke, le ndlela akavumeli ukuba abeke isifo ecacileyo.

Okwesibini, ukulinganisa refraction sokukhanya. Ugqirha zingasetyenziswa njenge lens lolungiso, kwaye umatshini okhethekileyo. Ugqirha ukhangela ngaxeshanye, ukhanyiso refracted ngokuchanekileyo xa kwicala iliso. Isebenzisa isixhobo okhethekileyo - retinoscope. Ke ugqirha icebisa ukuba bajonge etafileni ngenxa uxilongo ukujonga ngoncedo lens ezizodwa. Ukuba ezi lens ukunceda, urhulumente kuchazwa ngokuthi astigmatism. Nyango lungancedayo ukuba ekunene ukufumanisa ubuzaza iimpawu zesifo.

Okwesithathu, esebenzisa keratometry. Lo matshini umlinganiselo ugobile kwenwebu. A inwebu oluqhelekileyo idla macala, nakumndilili ugobile. Sigula astigmatism imilo engaqhelekanga, nto leyo ubona imoto. Kwakhona lokufunyaniswa esi sifo, keratometry ezisetyenziselwa nokukhethwa lenses nasemva imisebenzi esweni.

Okwesine, indlela kutshanje zaziswa of mphandle kwenwebu. Yeyona ndlela yempucuko. Xa isigulane ejonga kwindawo ethile ukumbuza, kwaye umatshini ivelisa amawaka yomlinganiselo thinnest. Kwi computer kagqirha ibonisa umfanekiso-onamacala amathathu iliso, apho zonke izinxaxhi nje ibonakale. Ngokuqhelekileyo le ndlela iyasetyenziswa xa kufuneka etyandiwe, kwaye ngamanye amaxesha yesithuba sokukhetha lens zoqhagamshelwano kubantu abane engaqhelekanga nokumila iliso.

Ukuba wena okanye unyango astigmatism omthandayo kunokwenzeka ayikho enye indlela. Enyanisweni, kukho ngokuqhelekileyo iindlela ezintathu ezisisiseko. Okokuqala, ukuba iindondo elungileyo ubudala. Okwesibini, ezinye lenses contact efanelekileyo. Kodwa kwiimeko kakhulu, Asinakuyenza ngaphandle uqhaqho. Nangona kotyando wambi wenziwe kwaye abanesidanga encinane astigmatism.

Glasses efanelekileyo phantse wonke umntu, kodwa ingxaki kukuba umbono zaphucuka kuphela xa isigulane nesizihlolisisayo. Kodwa ukuba umtha bavela, umfanekiso egqwethekileyo: isigulana kwi gumbi osinika uluvo lokuba iindonga nabavumayo kancinane. Ku nga ha va imvakalelo emnandi. Noko ke, ekuhambeni kwexesha abaninzi bayaziqhela kwaye qaphela inkqubo enkulu idla kuthatha malunga neveki. Abanye oogqirha astigmatism wobulali ngokubanzi bakhetha ukuba aphathe, njengoko ochaphazelekayo kancinci malunga izigulane.

Kwaye ukuba kukho wononophelo of astigmatism? Unyango nawo ngoncedo lenses, kodwa ngendlela ethile kuphela. lens oluqhelekileyo phendula xa idanyaze. Nangona kunjalo, ezi lenses zilungiswe ukuze abuyele kwisigxina sabo sokuqala. Ngoko ukubuyisela imilo mgaqweni le inwebu - ngaphandle isiphumo ugobile iindonga. Nangona kunjalo, olu khetho ezingafanelanga kakuhle kubantu abane komzimba, kwaye ecinywe amehlo avelana ngokungaqhelekanga.

astigmatism Strong? Treatment kwendlela yotyando eliza kusombulula ingxaki. Ngokuqhelekileyo, lo msebenzi ikhutshwa phandle usebenzisa laser. Ugqirha lutshintsha imilo inwebu, kodwa lo iqhekeza umsebenzi ebixhamla ubuncwane kunene, ngoko kukholosa amehlo akho kuphela ugqirha abakrelekrele kakhulu.

Kuyo nayiphi na imeko, unyango izakunceda ukuvala naluphi iqondo kunye uhlobo astigmatism. Jonga oculists ezilungileyo!
