Wake waya kudokotela ukuyohlolwa amehlo akho? Cishe uyakhumbula ukuthi lapho uya khona, babekukwenza uhlale esihlalweni, ulengise ishadi elikhulu odongeni kude, bese bekucela ukuthi ufunde izinhlamvu ezikuso ngamunye ngamunye. Kufanele ufunde kusukela ohlamvini oluphezulu kuya koluncane kunabo bonke, umugqa nomugqa. Ngezinye izikhathi kufanele uvale iso elilodwa, bese kuba elinye... Leso isivivinyo esilula kakhulu esisaziyo sonke, esibizwa ngokwezokwelapha ngokuthi i -Visual Acuity Test . Kalula nje, sihlola ukuthi amehlo akho abukhali kangakanani. Namuhla, sizoxoxa ngalokhu ngemininingwane eyengeziwe , njengokungathi ukhuluma nomngane.
Iyini ngempela le Visual Acuity Test?
Ukubona Okubonakalayo kumane kusho "ukucaca kokubona" noma "ubukhali bokubona". Kubhekisela endleleni ongakwazi ngayo ukuhlukanisa ngokucacile izimo nemininingwane ebangeni elithile. Uma uhamba emgwaqweni, ungakwazi yini ukufunda izinhlamvu ezisophawini olukude? Ungayibona inombolo ebhasini ukude? Izinto ezinjalo zinqunywa ukubona kwakho okubonakalayo.
Ngakho-ke lokhu kuhlolwa kuyindlela esheshayo nelula kakhulu yokuthi udokotela abone ukuthi umbono wakho ushintshile yini ngokuhamba kwesikhathi. Yisinyathelo sokuqala nesibaluleke kakhulu ekuhlolweni kwamehlo.
Kungani lolu vivinyo lubaluleke kangaka?
Lokhu kuhlola okulula kungabona izinkinga eziningi ezivamile emehlweni ethu kusenesikhathi. Ikakhulukazi, kusetshenziselwa ukuhlonza izinkinga ezine eziyinhloko ezaziwa ngokuthi amaphutha okubuyisa umbono.
- Ukubona eduze / I-Myopia: Yilapho ungabona khona izinto eziseduze nawe ngokucacile, kodwa izinto ezikude azicacile. Isibonelo, ukufunda incwadi kulungile, kodwa ukubuka i-TV noma ukubona inombolo ebhasini emgwaqweni akucaci.
- Ukubuka kude / i-Hypopia: Lokhu kuphambene nesimo sangaphambilini. Nakuba izinto ezikude zingabonakala ngokucacile, izinto eziseduze, ikakhulukazi uma ufunda incwadi noma iphephandaba noma ubheka ifoni, zibonakala zifiphele. Amehlo azizwa ekhathele.
- I-Astigmatism: Lesi yisimo esihlukile kancane. Ngenxa yokuthi iso aligxili kahle ekukhanyeni, ungase ubone izinto eziseduze nezikude njengokungathi ziphambene kancane, zeluliwe, noma azicacile. Esinye isibonakaliso salokhu ukubonakala kwemigqa ezungeze izibani zokukhanyisa lapho ushayela ebusuku.
- I-Presbyopia: Lesi akusona isifo. Yisimo semvelo esenzeka lapho ilensi yamehlo ethu ilahlekelwa ukuguquguquka kwayo ngemva kweminyaka engama-40. Lokhu kwenza kube nzima nokubona izinto eziseduze, njengokubuka iphephandaba noma ukubopha intambo.
Ngaphezu kwalezi zinkinga ezine eziyinhloko, lokhu kuhlolwa ngezinye izikhathi kungasetshenziswa njengesinyathelo sokuqala sokubheka izimo ezifana nokungaboni kahle kombala.
Kunezinhlobo eziningana zokuhlolwa kokubona okubukhali.
Sonke siyalazi ishadi elinezinhlamvu, kodwa empeleni kunezindlela eziningana zokwenza lokhu kuhlolwa. Kuyahlukahluka kuye ngobudala nezidingo zomuntu.
| Igama lokuhlolwa | Kalula nje... |
|---|---|
| Ishadi Lokuhlolwa Kwamehlo le-Snellen | Lena yindlela yakudala esiyaziyo sonke. Ishadi elisodongeni liya lincipha kancane kancane kusukela phezulu kuya phansi. Umbono ulinganiswa ngomugqa omncane kakhulu ongawufunda. Manje kwezinye izindawo, lokhu kuboniswe odongeni. |
| Ishadi le-E elingahleliwe | Lokhu kufana neshadi likaSnellen. Kodwa leli linohlamvu 'E' kuphela. Emugqeni ngamunye, uhlamvu u-E luphendulwa ngezindlela ezahlukene, njengaphezulu, phansi, kwesokudla, nakwesobunxele. Lokhu kungenziwa ngisho nangabantwana abancane abangakwazi ukufunda izinhlamvu, noma ngumuntu ongalwazi ulimi. Khomba nje ohlangothini lohlamvu 'E' olunemilenze emithathu. |
| Ukuhlolwa Kokubona Okubonakalayo Kwe-Pinhole | Lokhu kwenzelwa ukuhlonza ngokunembile isimo esifana nokungaboni kahle. Lapha, unikezwa ithuluzi (i-paddle) elinembobo encane noma imbobo eminingana. Ucelwa ukuthi ubheke kulowo mbobo bese ufunda ishadi. Lokhu kusiza ukulawula ukukhanya okungena esweni bese uthola ukuthi iyini ngempela inkinga yokubona. |
| Ukuhlolwa kwezingane (Ukuhlolwa kweCardiff) | Cabanga nje, uwahlola kanjani amehlo engane encane engakwazi ukufunda?Ngezikhathi ezinjengalezi, esikhundleni sezinhlamvu, basebenzisa ishadi elinezithombe ezahlukahlukene zezilwane, izimoto nezindlu. Udokotela ukhombisa izithombe bese ebuza ingane ukuthi ziyini. Lokhu kunikeza umbono wezinga lokubona kwengane. |
Yile ndlela kanye okusebenza ngayo ukuhlolwa:
Lena inqubo elula kakhulu. Lezi yizinyathelo ezivame ukulandelwa:
1. Ibanga: Uzohlaliswa noma ume esihlalweni esiqhele ngamamitha angu-20 ukusuka lapho ishadi likhona.
2. Ukuvala iso elilodwa: Okulandelayo, udokotela uzokutshela ukuthi uvale iso elilodwa ngesandla sakho noma ngethuluzi elincane elinikezwe lona. Awukwazi ukumane ubheke ngeminwe yakho, akunjalo?
3. Ukufunda izinhlamvu: Manje ucelwa ukuthi ufunde izinhlamvu ngokulandelana kusukela kuhlamvu olukhulu phezulu kweshadi, phansi.
4. Ukuthola Umkhawulo: Uyaqhubeka ufunda uze ufike ezingeni lapho ungakwazi ukufunda izinhlamvu ngokucacile, bese ziba mfushane.
5. Ukuhlola elinye iso: Uma iso elilodwa seliqedile, livule, uvale elinye iso, bese uphinda isivivinyo kusukela ekuqaleni.
Into ebaluleke kakhulu ukungashiyi amehlo bese uzama ukufunda lapho izinhlamvu zincane noma zingacacile. Ukwenza kanjalo kuzokuvimbela ekutholeni isithombe esinembile sokubona kwakho. Lokhu akuyona into okufanele 'uyiphumelele' njengokuhlolwa. Okubalulekile ukutshela udokotela wakho ngobuqotho ukuthi ubona kanjani.
Uma usuvele ugqoka izibuko noma ama-contact lens, udokotela wakho angase enze lokhu kuhlolwa kabili.
- Ngaphandle kwezibuko: Kala umbono wakho wemvelo (umbono ongalungisiwe).
- Ukugqoka izibuko: Hlola ukuthi izibuko zakho zamanje zilungisa kanjani ukubona kwakho.
Imiphumela ithini? Ukubona emuva kungama-20/20...
Uma isivivinyo sesiphelile, umbono wakho ubikwe ngezingxenyana. Cishe uke wezwa indaba "yombono ka-20/20." Bathi kumamuvi, "Umbono wakhe uphelele, u-20/20."
Incazelo yalokhu ilula kakhulu.
Umbono we-20/20 usho ukuthi into umuntu onamehlo aphilile ajwayelekile angayibona kahle ebangeni elingamamitha angu-20 ukusuka lapha izobonakala kahle ngendlela efanayo ebangeni elingamamitha angu-20 ukusuka lapha.
Cabanga ukuthi umbono wakho ungama-20/40. Lokhu kusho ukuthi ukuze ubone ngokucacile into umuntu ovamile angayibona ebangeni elingamamitha angu-40 ukusuka lapho, kufanele usondele ngamamitha angu-20. Lokhu kusho ukuthi umbono wakho webanga ungaphansi kwesilinganiso.
Futhi, uma umbono wakho ungama-20/15, kusho ukuthi umbono wakho ubukhali kunowejwayelekile. Ungabona ngokucacile usebangeni elingamamitha angu-20 lokho umuntu ojwayelekile angakubona esebangeni elingamamitha angu-3.
Kodwa khumbula, abantu abaningi abanawo umbono oqondile ngaphandle kokulungiswa. Lokho kuvamile. Ngemva kokuhlolwa, udokotela wakho uzokutshela ukuthi yini okudingeka uyenze ukuze ulungise umbono wakho. Ezimweni eziningi, kuzonikezwa izibuko noma ama-contact lens.
Ukuhlolwa Kokubona Okubonakalayo kuyingxenye eyodwa kuphela yokuhlolwa kwakho okuphelele kwamehlo. Ngemva kwalokhu, udokotela uzohlola umfutho wamehlo akho, imizwa engaphakathi kweso lakho, nezinye izinto eziningi esebenzisa ezinye izinto (isib. isibani esiqhekekile).
Umlayezo Wokuya Nawe Ekhaya
- Ukuhlolwa Kokubona Okubonakalayo kuyindlela elula kakhulu, engenabuhlungu, kodwa ebaluleke kakhulu elinganisa ubukhali bamehlo akho.
- Lokhu kusiza kakhulu ekutholeni kusenesikhathi izifo zamehlo ezivamile njengokubona eduze kanye nokubona kude.
- Ngesikhathi sokuhlolwa, khuluma nodokotela wakho ngendlela obona ngayo . Ungaphazamisi amehlo bese uzama ukufunda ngobunzima. Lokhu akusikho ukuhlolwa okufanele 'ukuphase'.
- Uma unezimpawu ezifana nekhanda elibuhlungu, ukukhathala kwamehlo, noma ukubona okufiphele, qiniseka ukuthi ubona udokotela futhi uhlolwe amehlo akho.
- Ukuze silondoloze ukubona okunempilo, kubaluleke kakhulu ukuhlolwa kwamehlo njalo . Njengabazali, kufanele sihlale sikhathazekile ngokubona kwezingane zethu.
