Ngaba nawe ubona izinto zingacacanga? Kusenokwenzeka ukuba kungenxa ye-astigmatism!

Ngaba wakha waphawula ukuba ezinye iileta azicacanga, zibonakala zithambile? Okanye xa uqhuba ebusuku, ubona imigca emincinci ejikeleze izibane endleleni, okanye ukukhanya kubonakala kuthambile? Ngamanye amaxesha sinokucinga ukuba kukudinwa nje kancinci kwamehlo ethu. Kodwa oku kusenokuba ngenxa yemeko encinci yamehlo ebizwa ngokuba yi-astigmatism . Ungakhathazeki, le yinto abantu abaninzi abanayo, kwaye inokulungiswa. Namhlanje, siza kuthetha ngale nto ngokulula, ngendlela onokuyiqonda.

Yintoni i-Astigmatism?

Ngamafutshane, i-astigmatism yingxaki encinci kwindlela ukukhanya okungena ngayo emehlweni ethu. Ngokuchanekileyo, ibangelwa kakhulu kukutshintsha okuncinci kwimo yenxalenye ecacileyo ephambi kwamehlo ethu, i-cornea . Ngamanye amaxesha, inokubangelwa kukutshintsha kwimo yelensi ngaphakathi kweliso.

Khawuthelekelele, iliso eliphilileyo line-cornea entle engqukuva, efana nebhola. Emva koko, imisebe yokukhanya evela ngaphandle idlula kule cornea ize igxile ngqo kwindawo enye ngaphakathi kweliso, eyi-retina. Kulapho sibona khona yonke into ngokucacileyo.

Kodwa umntu one-astigmatism une-cornea efana nebhola yombhoxo, okanye ende kancinci njengeqanda, okanye egobile kwicala elinye. Kwenzeka ntoni xa oko kusenzeka? Xa imisebe yokukhanya ingena elisweni, ayijolisi kwindawo enye. Endaweni yoko, ijolisa kwiindawo ezininzi, okanye njengomgca omnye. Kulapho sibona izinto zingacacanga, zinwebekile, kwaye ngamanye amaxesha ngathi zimbini. Kufana nokuba sijonga ngesipili esiphukileyo.

Umzekelo, unobumba u-"D" unokubonakala ngathi ngu-"B", okanye isangqa sibonakale ngathi yi-oval. Oku kwenzeka kakhulu kwi-astigmatism.

Kutheni kukho i-astigmatism? Zithini izizathu?

Kunzima ukuqaphela unobangela omnye we-astigmatism, kodwa kukho izinto ezininzi eziphambili ezibangela oku:

• I-genetic: Oku kudla ngokuba yimfuza. Oku kuthetha ukuba ukuba abazali bakho okanye umntu kusapho lwakho unale meko, unokuba nayo. Abantu abaninzi bazalwa benemilo engalinganiyo ye-cornea.
• Ukulimala Kwamehlo: Ukuba into ibetha okanye yenzakalisa iliso, imilo ye-cornea inokutshintsha ngamanye amaxesha. Oku kunokuba yimbangela ye-astigmatism.
• Utyando Lwamehlo: Emva kotyando lwamehlo oluthile, njengotyando lwe-cataract, imilo ye-cornea inokutshintsha kancinci. Nangona kunjalo, oku akwenzeki kuwo wonke umntu.
• Iimeko Zamehlo: Ezinye iimeko zamehlo ezingaqhelekanga, ezifana neKeratoconus, zinokubangela ukuba i-cornea ibe ncinci ize ifane nekhowuni. Oku kukwangunobangela omkhulu we-astigmatism.
• Ukuhlikihla okanye ukuhlikihla amehlo: Ukuhlikihla amehlo akho ngamandla okanye ukufaka uxinzelelo kwiinkophe zakho ixesha elide kuboniswe kwezinye izifundo ukuba kutshintsha imo ye-cornea. Nangona kunjalo, oku akusiyonto ixhaphakileyo.

Into ebalulekileyo kukuba, nokuba yintoni na imbangela, i-astigmatism yimeko enokulawulwa kwaye ilungiswe .

Uyazi njani ukuba une-astigmatism? Zithini iimpawu?

Ukuba une-astigmatism, unokufumana iimpawu ezahlukeneyo. Ayingabo bonke abantu abazifumana ngendlela efanayo. Abanye abantu basenokungaziva ntlungu kangako ukuba bane-astigmatism encinci.

Nazi ezinye zeempawu eziqhelekileyo :

• Umbono ofipheleyo okanye ogqwethekileyo: Olu luphawu oluphambili. Izinto ezikufutshane kunye nezo zikude zinokubonakala zifiphele kwaye zingacacanga. Ezinye izinto, ezinje ngoonobumba nemigca, zinokubonakala zigqwethekile.
• Ukuxinezeleka kwamehlo: Xa ufunda incwadi, ujonge ikhompyutha, okanye ubukele umabonwakude ixesha elide, amehlo akho asenokuziva ediniwe kakhulu kwaye esinda.
• Intloko ebuhlungu: Intloko ebuhlungu inokubakho, ingakumbi emva kokwenza umsebenzi ofuna ukusebenzisa amehlo omabini. Oku kusenokubangelwa kukuba amehlo asebenza kakhulu.
• Ukufinya amehlo: Ngenxa yokuba ungaboni kakuhle, ungalingeka ukuba ufinya amehlo ukuze ubone izinto ngokucacileyo.
• Ubunzima bokubona ebusuku: Ebusuku, ingakumbi xa uqhuba, unokubona ukukhanya okanye ii-halos ezijikeleze izibane. Oku kunokwenza kube nzima ukubona indlela ebusuku.
• Amehlo arhawuzelelwayo okanye atshayo: Abanye abantu basenokuba nokurhawuzelelwa okanye ukutsha rhoqo kwamehlo.
• Ukubona kabini kwiliso elinye: Oku kunqabile kancinci, kodwa abanye abantu banokubona izinto ezimbini nangona beneliliso elinye.

Ukuba unenye okanye ngaphezulu kwezi mpawu, kungcono ukufuna ingcebiso kagqirha.

Ungazi njani ngokuchanekileyo ukuba une-astigmatism?

Musa ukucinga ukuba une-astigmatism kuba nje unale mpawu. Kodwa ukuba unamathandabuzo, ngokuqinisekileyo kuya kufuneka ubonane nogqirha wamehlo okanye ugqirha wamehlo ukuze ahlolwe amehlo akho.

Basebenzisa iindlela ezahlukeneyo zokuhlola amehlo akho:

• Uvavanyo Lokubona Ngokucacileyo: Uza kucelwa ukuba ufunde itshathi enoonobumba namanani. Oku kunokulinganisa ukubona kwakho ngokucace gca.
• I-Keratometer okanye i-Corneal Topography:Ezi zixhobo zinokulinganisa ngokuchanekileyo ukugoba, okanye imo, ye-cornea yakho. Oku kunokunceda ekuqinisekiseni ukuba une-astigmatism kunye nokuba inzima kangakanani.
• I-Autorefractor: Esi sisixhobo esisebenzisa ukukhanya ukuze sifumane umbono ocacileyo wokuba loluphi uhlobo lwelensi eliyifunayo iliso.
• I-Phoropter kunye ne-Retinoscope: I-phoropter ngumatshini obamba ubuso bakho phambi kwakho kwaye utshintshe iilensi nganye nganye, ebuza, "Ingaba oku kucacile? Ingaba kucacile?" Ugqirha ukhanyisa iliso lakho nge-retinoscope aze ajonge indlela ukukhanya okujika ngayo ngaphakathi kweliso. Le yindlela ofumana ngayo amayeza afanelekileyo kuwe.

Zonke ezi mvavanyo azibuhlungu, ngoko ke akukho sizathu sokoyika.

Ziziphi iindlela zonyango lwe-astigmatism?

Iindaba ezimnandi zezokuba i-astigmatism yimeko enokulungiswa phantse ngokupheleleyo . Ugqirha wakho uza kukhetha unyango olufanelekileyo kuwe ngokusekelwe kwizinto ezifana nenqanaba le-astigmatism yakho, ubudala bakho, kunye nendlela ophila ngayo.

Kukho iindlela ezintathu eziphambili zonyango:

1. Iiglasi (Iiglasi zamehlo)

Olu lolona nyango luqhelekileyo nolulula. Abantu abane-astigmatism banikwa iiglasi ezineelensi ezisilinda ezenzelwe ngokukodwa. Ezi lensi zigxila kwimitha yokukhanya engadibaniyo ngaxeshanye ngenxa yokuma okungalinganiyo kwe-cornea kwindawo enye kwi-retina. Emva koko unokubona ngokucacileyo.

2. Iilensi zoQhagamshelwano

Iilensi zokunxibelelana ziyindlela elungileyo kubantu abangafuniyo ukunxiba iiglasi okanye abadlala imidlalo. Kukho iilensi zokunxibelelana ze-toric ezenzelwe ngokukodwa i-astigmatism. Ezi zahlukile kancinci kwiilensi zokunxibelelana eziqhelekileyo. Zingena kakuhle ngaphakathi kweliso kwaye zilungele i-astigmatism. Kwezinye iimeko ezinzima ze-astigmatism, kusetyenziswa uhlobo olubizwa ngokuba yi -Rigid Gas Permeable (RGP) lens .

3. Utyando lokuHlola

Oku kuquka ukusebenzisa iilaser ukuze kulungiswe i-cornea ngokusisigxina, kupheliswe i-astigmatism. Emva koku, akusayi kufuneka unxibe iiglasi okanye iilensi zoqhagamshelwano.

Kukho iintlobo ezininzi zotyando ezidumileyo:

• I-LASIK (iLaser-Assisted In Situ Keratomileusis): Kule nkqubo, kwenziwa i-flap encinci kwi-cornea kwaye kuthunyelwa i-laser beam phantsi kwayo ukuze ibumbe i-cornea ngokutsha.
• I-PRK (i-Photorefractive Keratectomy): Kule nkqubo, umaleko ongaphezulu we-cornea uyasuswa kwaye kusetyenziswa umqadi we-laser.
• NCUMELA (Ukukhupha iLenticule encinci): Le yindlela entsha yotyando lwelaser.

Olu tyando alufanelekanga kuye wonke umntu. Ugqirha uza kugqiba ukuba ufanelekile na okanye akunjalo ngokusekelwe kwizinto ezininzi, ezifana nemeko yamehlo akho, ubudala kunye nempilo yakho.

Ngaba abantwana abancinci bafumana i-astigmatism?

Ewe, i-astigmatism yimeko ebonakala kubantwana abancinci. Abanye abantwana bazalwa benale meko. Kubaluleke kakhulu ukuqaphela izinto ezinjalo kwangethuba ukuze amehlo abantwana akhule kakuhle. Ngaphandle koko, inokuchaphazela ukusebenza kwabo kwezemfundo, ukudlala, kunye nemisebenzi yemihla ngemihla.

Njengomzali, ungajonga umntwana wakho:

• Ngaba umntwana uhlala efinya amehlo?
• Ngaba usondeza ubuso bakho kakhulu xa ufunda iincwadi okanye ubukele iTV?
• Ngaba uhlala uthetha ngentloko ebuhlungu?
• Ngaba amehlo akho abomvu kwaye anamanzi?
• Ngaba uzama ukubona ngeliso elinye livaliwe?

Ukuba ubona into efana nale, eyona nto ingcono onokuyenza kukusa umntwana wakho kugqirha wamehlo ngokukhawuleza. Ukuba uzibona kwangethuba ezi mpawu, zinokunyangwa ngeglasi kuphela.

Umyalezo esifanele siwuthathe koku

Kulungile, ngoko ke ndicinga ukuba ngoku unombono ongcono malunga ne-astigmatism.

Into ebalulekileyo kukuba i-astigmatism ayiyonto yokoyika. Yimeko eqhelekileyo kwaye inokulungiswa.

• Ukuba uhlala ubona izinto ezingaqhelekanga, uxinezelekile, uxinezelekile emehlweni, okanye uneentloko ezibuhlungu, musa ukuzityeshela kwaye ngokuqinisekileyo bonana nogqirha wamehlo ukuze ahlolwe amehlo akho.
• Kubaluleke kakhulu ukuba amehlo akho ahlolwe rhoqo . Oku kuya kukunceda ufumanise kungekuphela nje iimeko ezinje, kodwa nezinye iingxaki ezinxulumene namehlo kwangethuba.
• Sebenzisa iiglasi okanye iilensi zokunxibelelana ezichazwe ngugqirha wakho ngokuchanekileyo nangokuthe rhoqo.
• Lumka ngokukodwa umbono wabantwana abancinci. Ubaluleke kakhulu kwikamva labo.

Amehlo akho yenye yezona zinto zixabisekileyo onazo, ngoko ke luxanduva lwakho ukuwanyamekela.
