Ngaba amehlo omabini ayatsha lilanga? Makhe sithethe nge (Photokeratitis)!

Ngaba wakha wachitha usuku olude udlala elangeni, uhamba elunxwemeni, okanye utshisela, uze xa ufika ekhaya ngokuhlwa, amehlo akho abomvu, anamanzi, kwaye abuhlungu, ngokungathi unesanti emehlweni akho? Ngamanye amaxesha amehlo akho ayadumba kwaye kunzima ukujonga ukukhanya, akunjalo? Ukuba ukhe waba namava anjalo, kusenokuba ngenxa yemeko ebizwa ngokuba yi-photokeratitis. Ngamafutshane, kufana nolusu lwethu olutshiswa lilanga, kodwa amehlo ethu atshiswa lilanga yimitha ye-UV.

Yintoni kanye kanye le (iPhotokeratitis)?

I-Photokeratitis, ngokufutshane, kuxa umphezulu wamehlo ethu, i-conjunctiva , i-membrane emhlophe egubungela inxalenye emhlophe yeliso ejikeleze iliso elimnyama, kunye ne-cornea , inxalenye ecacileyo ephambi kweliso elimnyama, yonakaliswa kukuvezwa kwimitha ye-ultraviolet (UV) evela elangeni. Kufana nje xa ulusu lwethu lutshiswa lilanga, luba bomvu kwaye lube buhlungu. Kodwa oku kwenzeka emehlweni. Uninzi lwexesha, le meko ichaphazela omabini amehlo.

Khawucinge nje, xa sisiya elunxwemeni, okanye xa sihamba ngeenyawo, okanye xa sisiya kwindawo enekhephu, kungekuphela nje ilanga, kodwa nokukhanya kwelanga okubonakaliswa ngamanzi, isanti, nekhephu kubetha ngqo emehlweni ethu. Kwakhona, ukukhanya okugqithisileyo okuvela ekudibaniseni, izibane ezisetyenziswa kwiibhedi zokuthambisa, kunye nezinye izibane zonyango nazo zinokubangela le meko. Abanye bathi oku "kubumfama bekhephu" kuba kubangelwa yimisebe ye-UV ebonakaliswa yikhephu. Phakathi kwabawelda, oku kwaziwa ngokuba yi-"Arc eye" okanye "i-Welder's flash."

Ziziphi iintlobo eziphambili ze-photokeratitis?

Le meko (iPhotokeratitis) inokwahlulwahlulwa ibe ziintlobo ezimbini eziphambili:

1. I-Acute Photokeratitis: Oku kwenzeka xa uchaphazeleka kakhulu yimitha ye-UV ngequbuliso, emva kwexesha elifutshane. Ngokuqhelekileyo kuba yinto yexeshana kwaye kuya kuba ngcono kwiintsuku ezimbalwa.

2. I-Chronic Photokeratitis: Oku kwenzeka ngenxa yokuvezwa kancinci kancinci kumanqanaba aphantsi emitha ye-UV ixesha elide. Olu hlobo aluxhaphakanga kangako njengohlobo olukhawulezileyo.

Uzibona njani iimpawu zoku?

Ukuba une-photokeratitis, unokufumana enye okanye ngaphezulu kwezi mpawu:

• Intlungu okanye ukubomvu kwamehlo: Olu luphawu oluphambili. Kusenokuvakala ngathi ingaphakathi lamehlo akho liyabuhlungu.
• Iinyembezi/amehlo anamanzi: Kusenokuvakala ngathi kukho iinyembezi eziphumayo.
• Umbono ofipheleyo: Usenokungakwazi ukubona kakuhle, kwaye umbono wakho usenokubonakala ufiphele.

• Uvelwano ekukhanyeni: Amehlo aba luhlaza okwesibhakabhaka kakhulu ukuba angajongwa, kwaye nokukhanya okuncinci kunzima ukukunyamezela.
• Ukuvakalelwa ngathi kukho iinkozo zesanti emehlweni: Kungavakala ngathi kukho into enamathele ngaphakathi emehlweni, ngokungathi ayahlaba.

Ukongeza koku, kunokubakho nezinye iimpawu:

• Ukubona ukukhanya: Xa ujonge ukukhanya, ungabona izangqa ezinemibala ezikujikelezileyo.
• Intloko ebuhlungu: Intloko ebuhlungu inokubakho.
• Ukuqhaqhazela kweenkophe: Kusenokuvakala ngathi inkcenkce iyaqhaqhazela nje.
• Ukulahlekelwa kokubona okwethutyana: Oku kunqabile kancinci, kodwa kunokwenzeka.
• Ukubona izinto zitshintsha umbala: Oku kukwayinto engaqhelekanga.

Ezi mpawu zihlala ziphakathi kweeyure ezi-6 nezingama-24. Kodwa kwiimeko ezininzi, ziya kuphela ngokupheleleyo kwiiyure ezingama-48. Okukhona uchitha ixesha elide ujongene nemitha ye-UV, kokukhona iimpawu zakho zinokuba nzima ngakumbi.

Zithini izizathu eziphambili ze-photokeratitis?

Imitha ye-Ultraviolet (UV) yiyo ebangela lo monakalo emehlweni ethu. Zombini imitha ye-UV-A kunye ne-UV-B evela elangeni zinokubangela umonakalo wexesha elifutshane kunye nexesha elide emehlweni ethu, kwaye zinokuchaphazela nokubona kwethu. Imitha ye-UV-C ifunxwa ngumaleko wethu we-ozone, ngoko ke ayilimazi amehlo ethu.

Ukongeza ekukhanyeni kwelanga ngqo, eminye imithombo yemitha ye-UV enokubangela i-photokeratitis iquka:

• Ukukhanya kwelanga okubonakalisa izinto ezifana nekhephu, umkhenkce, amanzi, isanti, okanye isamente kwaye kubetha amehlo ethu.
• (Iibhedi zokuthambisa isikhumba) okanye izibane ezisetyenziswa kwiikhabhini.
• Isibane selaser.
• Izibane zomphunga weMercury okanye izibane zedesika zehalogen.
• Umbane ubetha okanye iintlantsi zombane.
• Izixhobo zokuwelda ze-arc okanye izibane zemifanekiso ezikhupha amanzi.
• Ukukhanya okusetyenziselwa ukubulala iintsholongwane okanye njengonyango lwezonyango.

Kubalulekile: Ukujonga ngqo eLangeni, ingakumbi ngexesha lokusithwa lilanga, kunokubangela umonakalo omkhulu nohlala ixesha elide kwi-retina yethu, nto leyo enokubangela ukutsha. Ngoko ke ungaze ukwenze oko.

Ngubani osengozini enkulu yokuhlaselwa yile meko?

Usemngciphekweni omkhulu wokufumana i-photokeratitis ukuba:

• Ukuba ungumntu ochitha ixesha elininzi ngaphandle naselangeni, esenza izinto ezinjengokuhamba intaba, ukuhamba emahlathini, ukutyibiliza eqhweni, okanye ukudada.
• Ukuba usebenzisa (isibane selanga), (ibhedi yokuthamba), okanye ukuba usebenza okanye uchitha ixesha kwindawo enomthombo wokukhanya (we-UV).
• Ukuba uhlala kwiindawo eziphakamileyo kakhulu (ukuvezwa kakhulu kwimitha ye-UV).

Ziziphi iingxaki ezinokubakho ngenxa ye-photokeratitis?

Ukuchanabeka nakwimitha ye-UV encinci kangangexesha elide kunokunyusa umngcipheko wokuba ne -cataracts okanye i-macular degeneration kwixesha elizayo.Umngcipheko wokufumana ezi meko zilandelayo unokwanda. Ukuvezwa kwimitha ye-(UV) kuyaqokelelana ngokuhamba kwexesha. Kwakhona, ukuvezwa kwimitha ye-(UV) ixesha elide kunokubangela ukuphakama kwezicubu kumphezulu weliso. Ezi zibizwa ngokuba yi- (Pingueculae) kunye ne-(Pterygia) . Ezi zinokuthintelwa ngokusebenzisa iiglasi zelanga ngokufanelekileyo xa ungaphandle.

Ukongeza, ukukhanya okuluhlaza okwesibhakabhaka nokuluhlaza okotshani okuphuma kumaza amafutshane anjengezibane ze-(LED), iikhompyutha, kunye neefowuni eziphathwayo nako kunokuba yingozi kwii-retinas zethu kwaye kunokuba ngumngcipheko wokuwohloka kwe-macular kamva ebomini.
