Wake waba nenkinga yokwahlulela ukuthi imoto ephambi kwakho ikude kangakanani ngenkathi uhamba emgwaqweni? Noma wake wafinyelela ingilazi yamanzi etafuleni wayishaya ngephutha? Noma mhlawumbe awukwazanga ukuthola ukuthi kufanele unyathele kuphi lapho wehla ngezitebhisi. Izinto ezinjengalezi zingase zenzeke kithi ngezinye izikhathi. Isizathu esiyinhloko salokhu ukuthi amehlo ethu anomehluko omncane ekhonweni lawo lokunquma ngokunembile ibanga, usayizi, kanye nokujula kwento, okubizwa ngokuthi 'ukuqonda okujulile'.
Kuyini Ukuqonda Okujulile?
Kalula nje, ukuqonda okujulile yikhono lethu lokubona izinto ezinezici ezintathu (3D). Okusho ukuthi, kusisiza ukuqonda hhayi nje ukuphakama nobubanzi bento ethile, kodwa nokujula kwayo, ukuthi ikude kangakanani nathi, nokuthi inkulu kangakanani. Lokhu akuyona nje enye into, kuyinto emangalisayo kakhulu eyenziwa izingxenye eziningi zamehlo ethu kanye nobuchopho bethu ndawonye.
Zicabange ufunda lesi sihloko efonini yakho. Isikrini sefoni nombhalo okuso akulingani, kuqondile kuwe. Uyabona ukuthi umbhalo usesikrinini nokuthi ifoni isesandleni sakho. Lelo khono elisisiza sibone izinto ngezinga ezintathu (3D) yilokho esikubiza ngokuthi ukuqonda okujulile. Ngaphandle kwaleli khono, umhlaba wonke esiwubonayo ubuzobukeka njengesithombe esiqondile.
Kungani ukuqonda okujulile kubalulekile kithi?
Lokhu akukhona nje ukubona izinto kahle. Kubaluleke kakhulu nasekuphepheni kwempilo yethu yansuku zonke .
- Uma ushayela: Leli khono libalulekile ekuqondeni ibanga lemoto engaphambili, ibanga lomuntu owela umgwaqo, nokuthi ikhona yini indawo yokupaka imoto.
- Uma uhamba emgwaqweni: Lokhu kuyadingeka uma ukhuphuka futhi wehla izitebhisi, uma ugwema imbobo emgwaqweni, nalapho uhamba phakathi kwesixuku.
- Uma udlala: Cabanga udlala ikhilikithi. Ukuqonda okujulile kuyadingeka ukuze kunqunywe ngokunembile isikhathi sokushaya ibhola elizayo, isivinini sebhola, kanye nendawo yokulibamba.
Kalula nje, leli khono lisisiza siqonde indawo kanye nebanga lezinto cishe kuyo yonke imisebenzi esiyenzayo.
Isebenza kanjani le nto ebizwa ngokuthi ukuqonda okujulile?
Lena inqubo eyinkimbinkimbi kancane, kodwa masiyigcine ilula. Lena yingxenye yesistimu yethu ebizwa ngokuthi 'iNdlela Ebonakalayo'. Kwenzeka ngezinyathelo ezimbalwa:
1. Ukukhanya okungena esweni: Okokuqala, ukukhanya okuvela entweni esiyibonayo kungena esweni lethu.
2. I-Retina kanye ne-Optic Nerve: Lokhu kukhanya kuwela ku -retina , isikrini esingemuva kweso, bese kuguqula lolo lwazi lube yizimpawu zikagesi. Lezi zibonakaliso zibe sezithunyelwa emthanjeni wethu we-optic .
3. I-Optic chiasm: Izinzwa ze-optic ezivela emehlweni ethu womabili zihlangana ngesimo sika-'X' ngaphambili kobuchopho. Lokhu kubizwa ngokuthiIbizwa ngokuthi i-Optic Chiasm.
4. I-Visual cortex: Okokugcina, lolu lwazi luya engxenyeni yobuchopho ezinikele ekuboneni, i-visual cortex , ehlanganisa izithombe ezivela emehlweni womabili, ihlaziye umehluko omncane kuwo, futhi idale isithombe esiphelele esinezinhlangothi ezintathu (3D) esisibonayo.
Ngokuvamile, sidinga womabili amehlo, noma umbono we-binocular , ukuze sibe nokuqonda okunembile kokujula. Uma sibheka ngamehlo womabili, sibona into efanayo kusuka kuma-engeli amabili amancane, ngakho-ke kulula ngobuchopho ukubala ibanga nokujula ngokunembile. Kodwa-ke, ngisho nakumuntu oneso elilodwa kuphela (umbono we-monocular) , ngokuhamba kwesikhathi ubuchopho buyajwayela lokhu futhi buyakwazi ukubona ukujula ngezinga elithile. Kodwa-ke, kungase kungabi yinkimbinkimbi njengalapho sibona ngawo womabili amehlo.
Yiziphi izimo zezokwelapha ezivamile ezithinta ukuqonda okujulile?
Uma kunenkinga ngamehlo ethu noma ekusebenzeni kokubona ebuchosheni bethu, kungathinta nokuqonda kwethu okujulile. Nazi ezinye zezimo ezivamile.
| Isimo sezokwelapha | Kalula nje... |
|---|---|
| Ukubona Okuphansi | Izinkinga zokubona ezifana nokubona kude kanye nokubona eduze zivimbela amehlo ekuthumeleni isithombe esicacile ebuchosheni, okwenza kube nzima ukubona ukujula. |
| I-Strabismus | Amehlo awakhombisi ohlangothini olufanayo, kodwa iso elilodwa liphendukela ohlangothini oluhlukile. Lokhu kwenza kube nzima ngobuchopho ukuhlanganisa lezi zithombe ezimbili bese kwakheka isithombe se-3D. |
| Iso elivilaphayo (i-Amblyopia) | Umbono kwelinye iso ubuthakathaka kakhulu kunelinye. Lokhu kubangela ubuchopho ukuba bungazinaki izimpawu ezivela esweni elibuthakathaka. Lokhu kuthinta nokuqonda okujulile. |
| Ukulimala kwamehlo | Uma kwenzeka ingozi elimaza iso, ikakhulukazi i-optic nerve, ulwazi olufinyelela ebuchosheni lungaphazamiseka futhi ukuqonda okujulile kungalahleka. |
Ngingazi kanjani ukuthi nginenkinga ngokubona kwami ngokujula?
Uma ubona noma yiziphi izinguquko embonweni wakho, qaphela. Uma unezinye zalezi zimpawu, kungcono ukubona udokotela .
| Nakani lezi zimpawu. | |
|---|---|
| Umbono ofiphele | Uma izinto zibonakala zifiphele futhi zingabonakali kahle. |
| Ukubona kabili (i-Diplopia) | Uma into eyodwa ibukeka njengezimbili. |
| Ubuhlungu obusha bamehlo | Ubuhlungu bamehlo obuvela ngaphandle kwesizathu futhi obungapheli ezinsukwini ezimbalwa. |
| Ukuzwela ekukhanyeni | Uma amehlo akho ezwakala eluhlaza okwesibhakabhaka ngisho nasekukhanyeni okuvamile. |
| Ukuwohloka kombono | Uma unomuzwa wokuthi umbono wakho uya ngokuya uba mubi kakhulu. |
Ingabe ukuqonda kwethu okujulile kuncipha ebusuku?
Lona umbuzo abantu abaningi abawubuzayo. Nakuba ngokuvamile sibona kancane ebusuku ngenxa yokuntuleka kokukhanya, ikhono lethu lokubona ukujula akufanele lincishiswe. Okusho ukuthi, kufanele sikwazi ukuqonda ibanga nobukhulu bento ngisho nasebusuku.
Kodwa uma ukubona kwakho ebusuku kubi kakhulu kunezinye, okwenza kube nzima ukushayela, kungaba uphawu lwesimo esibizwa ngokuthi 'ubumpumputhe basebusuku' (i-Nyctalopia) . Uma ubhekana nalokhu , bona udokotela ngokushesha..
Yiziphi izindlela zokwelapha lezi zinkinga?
Esikhathini esiningi, ikhambi lalokhu lilula kakhulu: lungisa ukubona kwakho.
- Izibuko noma ama-contact lens: Uma ungakaze ugqoke izibuko ngaphambili, ungadinga izibuko noma ama-contact lens. Uma usuvele uwagqokile, kungadingeka ushintshe umuthi wakho kadokotela.
- Ukwelashwa kwesimo esiyisisekelo: Uma unesinye isimo sezokwelapha, njenge-strabismus, udokotela wakho uzochaza ukwelashwa okudingekayo (mhlawumbe ukuzivocavoca noma ukuhlinzwa) kwaso.
Siwanakekela kanjani amehlo ethu?
- Uma ubona noma yiziphi izinguquko embonweni wakho, ngisho noma zincane kakhulu, tshela udokotela wakho.
- Uma ugqoka izibuko, hlola amehlo akho njalo bese ubuyekeza imithi yakho kadokotela.
- Uma udlala imidlalo noma wenza umsebenzi ongaba yingozi emehlweni akho (isib. ukushisela, ukusaha ukhuni), gqoka izibuko zokuphepha ezifanelana nawe.
Yiziphi izikhathi ezinhle kakhulu zokuya kudokotela?
Lokhu kubaluleke kakhulu. Bonana nodokotela ngokushesha nje lapho ubona noma yiziphi izinguquko embonweni wakho. Ungacabangi nje ukuthi, "Lokhu kuzophela ezinsukwini ezimbalwa." Kungaba yinto elula, kodwa futhi kungaba uphawu lokuqala lwesimo esibucayi. Ngakho ungalindi kuze kube yilapho izimpawu zakho ziba zimbi kakhulu.
Into ebaluleke kakhulu ukuthi, uma ulahlekelwa umbono wakho ngokuzumayo, noma uma uzwa ubuhlungu obukhulu bamehlo, hamba uye eMnyangweni Wezimo Eziphuthumayo (ETU) wesibhedlela esiseduze ngokushesha.
Ukuqonda kwethu okujulile kuyikhono elibalulekile elisinika ulwazi oluningi mayelana nendawo esizungezile ngamehlo ethu. Ngaphandle kwalo, umhlaba esiwubonayo ubuyoba oyisicaba futhi ongenasimo. Ngakho-ke nakekela amehlo akho. Ungawushayi indiva ngisho noshintsho oluncane embonweni wakho.
Umlayezo Wokuya Nawe Ekhaya
- Ukuqonda okujulile kuyikhono elibalulekile elisisiza sibone umhlaba ku-3D futhi siqonde ibanga nobukhulu bezinto.
- Lokhu kudinga ukuthi amehlo ethu kanye nobuchopho bethu bube nempilo futhi busebenzisane.
- Uma unezimpawu ezifana nokungaboni kahle, ukubona kabili, noma ubuhlungu bamehlo obusha, ungazinaki.
- Ngokuvamile, lezi zinkinga zingalungiswa ngokusebenzisa izibuko noma ama-contact lens afanele.
- Uma ubona noma yiziphi izinguquko embonweni wakho, bonana nodokotela ngokushesha.Uma kwenzeka ulahlekelwa umbono ngokuzumayo noma ubuhlungu obukhulu, iya ku-ETU ngokushesha.
