Iziphi izizathu zokubona okungacaceki ngeliso linye?
Ukukhanya kweliso linye kuyinkinga evamile abantu abaningi ababhekana nayo ngesinye isikhathi ekuphileni kwabo. Kungahle kwenzeke ngokuzumayo noma kancane kancane ngokuhamba kwesikhathi, okungadida futhi kukhathaze. Uma eliso linye likhanya, kungaba nomuzwa wokungakhululeki futhi kwenze imisebenzi yansuku zonke, njengokufunda noma ukuqhuba, ibe nzima. Le nkinga ivame ukuphakamisa imibuzo enjengokuthi, "Yini ebangela ukukhanya kweliso linye?" noma "Kungani iliso lami likhanya?"
Kubalulekile ukuqonda izizathu ezahlukene zalesi simo. Izinkinga ezilula zokubona zingayibangela, kodwa kungase kube nezinkinga ezinzima kakhulu ezihilelekile. Uma uqaphela ukuthi elinye lamaliso akho likhanya, kubalulekile ukulithatha ngokungathi sína. Ukuthola iseluleko sezokwelapha kungakusiza ukuthola ukuxilongwa okulungile nokwelashwa.
Abantu abaningi bayazidela lezi zibonakaliso, becabanga ukuthi ziyophela zodwa. Noma kunjalo, kubalulekile ukuqonda ukuthi ukukhanya kweliso linye kungabonisa izinkinga zempilo ezivamile nezingavamile. Kungakhathaliseki ukuthi ucabanga ukuthi izimpawu zakho zincinyane kangakanani, ukufinyelela ochwepheshe bezempilo kungakusiza uzizwe ukhululekile futhi unolwazi. Ukunakekela ukubona kwakho kubalulekile, ikakhulukazi uma elinye lamaliso akho likhanya.
Izimbangela Ezivamile Zokukhanya Kweliso Linye
1. Iphutha Lokubona
Iphutha lokubona, njengokubona okude (myopia), ukubona okuphindwe kabili (hyperopia), noma i-astigmatism, kungabangela ukubona okukhanyayo kweliso linye. Lokhu kwenzeka ngenxa yesimo esingalungile seliso, esithinta indlela ukukhanya kugxila ngayo e-retina.
2. Ukukhathala Kwamehlo
Ukusebenzisa isikhathi eside isikrini, ukufunda, noma ukugxila emisebenzini eseduze kungabangela ukukhanya okwesikhashana kweliso linye ngenxa yokukhathala noma ukusetshenziswa kakhulu kwemisipha yamehlo.
3. I-Dry Eye Syndrome
Ukukhiqizwa okungenele kwamehlo noma amehlo angakhulu kungabangela ukwomile, okubangela ukubona okukhanyayo kweliso linye noma womabili. Izici zemvelo noma isikhathi eside sesi-screen zingenza lesi simo sibe sibi.
4. Ukuqothuka noma Ukulimala kwe-Cornea
Ukuqothuka noma ukulimala kwe-cornea kungabangela ukubona okukhanyayo kweliso linye, okuvamile okuhambisana nokungakhululeki, ubobu bombala, noma ukusabela ekukhanyeni.
5. I-Cataracts
I-Cataracts, ebangela ukufiphaza kwelensi yamehlo, ingase ithuthukiswe kweliso linye kuqala, okubangela ukukhanya okuqhubekayo. Lokhu kuvame kakhulu kubantu abadala.
6. Izinkinga ze-Retina
Isimo njengokwahlukana kwe-retina noma i-macular degeneration kungonakalisa ukubona kweliso linye, okuvamile kudinga ukunakekelwa ngokushesha kwezokwelapha.
7. Ukutheleleka noma Ukuvuvukala
Ukutheleleka njenge-conjunctivitis noma ukuvuvukala okuvela kwi-uveitis kungabangela ukukhanya, ubobu bombala, nokuvuvukala kweliso linye.
Okungavamile kodwa okubalulekile
Imbangela | Inkulumo | Amanothi engeziwe |
|---|---|---|
I-Optic Neuritis | Ukuvuvukala komthambo wamehlo kubangela ukulahleka kokubona ngokuzumayo noma ukukhanya. Ngokuvamile kuhlotshaniswa ne-MS. | Kungabangela nobuhlungu ngemuva kweliso nokulahleka kombala wokubona. Ukwelashwa ngokushesha kubalulekile. |
Isiguli noma i-Transient Ischemic Attack (TIA) | Ukuvinjwa noma ukuqhekeka kokugeleza kwegazi ebuchosheni kubangela ukushintsha kokubona ngokuzumayo. | Ngokuvamile kuhambisana nezinye izimpawu njengobunqunu noma ukungabi namandla. Ukunakekelwa kwezokwelapha ngokushesha kuyadingeka. |
Ukuvalwa kwe-Retinal Vein noma i-Artery | Ukuvinjwa kwamagagasi egazi e-retina, okubangela ukulahleka kokubona ngokuzumayo noma ukukhanya. | Kungabangela ukonakala kokubona okungapheli uma kungelashwa ngokushesha. |
I-Diabetic Retinopathy | Ukonakala kwamagagasi egazi e-retina ngenxa yokulawulwa okungelona kahle kweswekile kubangela ukubona okukhanyayo noma okuphambukayo. | Imbangela ehamba phambili yokufuna kwamehlo kubantu abadala. Kudinga ukuphathwa kahle kweswekile nokutholwa kwangaphambi kwesikhathi. |
I-Uveitis | Ukuvuvukala kweqembu eliphakathi kweliso kubangela ukukhanya, ubuhlungu, nokusabela ekukhanyeni. | Kungabangela ukonakala kokubona okungapheli uma kungelashwa ngendlela efanele. |
I-Glaucoma | Ukunyuka kokucindezela ngaphakathi kweliso konakalisa umthambo wamehlo, okubangela ukonakala kokubona. | Izinyathelo zokuqala zingase zithinte eliso linye kuphela, kodwa ukonakala okuqhubekayo kungabangela ukufuna uma kungelashwa. |
Nini Okufanele Ufunesele Ukunakekelwa Kwezokwelapha
Ukulahleka Kokubona Ngokuzumayo: Uma uhlangabezana nokukhanya ngokuzumayo noma ukulahleka kokubona okuphelele kweliso linye, funa ukunakekelwa kwezokwelapha ngokushesha.
Ukukhanya Okuqhubekayo: Uma ukubona okukhanyayo kuqhubeka okwengeziwe amahora ambalwa noma kubi, xhumana nodokotela wezokunakekelwa kwezempilo ukuze uthole ukuxilongwa okulungile.
Ukukhanya Okuhlungu: Ukukhanya okuhambisana nobuhlungu beliso, ukungakhululeki, noma ukusabela ekukhanyeni kufanele kuhlolwe yisazi sezokwelapha.
I-Floaters noma I-Flashes Yekhanya: Uma ukukhanya kuhambisana nokubona i-floaters, i-flashes yekhanya, noma izithunzi ekuqondeni kwakho, kungabonisa izinkinga ze-retina.
Izibonakaliso Zesiguli noma i-TIA: Uma ukubona okukhanyayo kuhambisana nobuthakathaka, ukungabi namandla, ubunzima bokukhuluma, noma ukukhungatheka, funa ukunakekelwa kwezokwelapha okusheshayo njengoba kungabonisa isiguli noma i-TIA.
Ukulimala Kwengqondo Muva Nje: Uma usanda kuhlangabezana nokulimala ekhanda noma emehlweni futhi uthuthukise ukubona okukhanyayo, funa ukuhlolwa kwezokwelapha ngenxa yomonakalo ongaphakathi.
Isimo Sempilo Esiqhubekayo: Abantu abanesimo njengeswekile noma ukucindezela kwegazi okuphezulu kufanele babuze udokotela uma behlangabezana nokubona okukhanyayo, njengoba lokhu kungabangela izinkinga ze-retina.
Izimpawu Ezibi: Uma ukukhanya kuya kubi ngokuqhubekayo, noma kuhlotshaniswa nokuhlanza noma ukugabha, kubalulekile ukufuna usizo lochwepheshe.
Isifinyeto
Ukubona okukhanyayo kweliso linye kungabangelwa izimbangela ezihlukahlukene, kusukela ezimweni ezilula njengephutha lokubona kuya ezinkingeni ezinzima njenge-optic neuritis, isiguli, noma ukuvalwa kwe-retina. Izimbangela ezingavamile kodwa ezibucayi zihlanganisa i-diabetic retinopathy, i-uveitis, ne-glaucoma. Ukulungiswa kwezokwelapha ngokushesha kuyadingeka uma ukubona okukhanyayo kuzumayo, kuqhubeka, noma kuhambisana nezinye izimpawu njengobunhlungu, i-floaters, noma izibonakaliso zesiguli.
Ngaphezu kwalokho, uma ukubona okukhanyayo kulandela ukulimala ekhanda, kuhlotshaniswa nezimo zempilo eziqhubekayo, noma kubi ngokuhamba kwesikhathi, ukufuna ukunakekelwa kochwepheshe kubalulekile ukuvimbela ukonakala kwesikhathi eside. Ukuxilongwa kwangaphambi kwesikhathi nokwelashwa kuyisihluthulelo sokulondoloza impilo yamehlo.
