Ngaba wakha wahamba esitratweni waza ngequbuliso wema xa wabona imoto ivela ecaleni? Okanye wakha wahlala egumbini wajonga phambili wabona umntu ehamba ngekona yeliso lakho? Yiloo nto siyibiza ngokuba yi-peripheral vision . Sonke sisebenzisa olu buchule kubomi bethu bemihla ngemihla singaqondi. Ngoko ke, masithethe ngayo ngokweenkcukacha ezithe vetshe namhlanje.
Yintoni umbono ongaphandle?
Ngamafutshane, xa ujonge phambili ungashukumisi intloko yakho, yonke into oyibonayo emacaleni, ngaphezulu nangaphantsi iyinxalenye yombono wakho ongaphandle. Yiyo loo nto sithi "ukubona ngekona yeliso lakho."
Oko ukubonayo xa ugxila ngqo kwinto ethile kuthiwa ngumbono wakho ophambili . Lo mbono uhlala ucacile kwaye ubukhali.
Khawuthelekelele ufunda incwadi. Amehlo akho agxile ngokupheleleyo kwisicatshulwa. Ngumbono wakho oyintloko lowo. Kodwa kwangaxeshanye, awukwazi ukubona izinto ezingaphaya kwencwadi, njengebhotile yamanzi etafileni, okanye umntu odlulayo. Loo mbono ungaphandle.
| Uphawu olubonakalayo | Umbono oPhakathi | Umbono oPhakathi |
|---|---|---|
| Ukucaca | Icacile kakhulu kwaye icacile. Iinkcukacha zibonakala ngokucacileyo. | Ukucaca akucacanga. Iinkcukacha azibonakali ngokucacileyo. |
| Ukuqaphela umbala | Imibala ingahlulwa kakuhle kakhulu. | Ukuqatshelwa kombala akulunganga. |
| Ukuchonga intshukumo | Kulungile, kodwa asingomsebenzi uphambili. | Ibuthathaka kakhulu. Nokuba intshukumo incinci kangakanani na iyabonakala ngokukhawuleza. |
| Ukusetyenziswa okuphambili | Ukufunda, ukubona ubuso, ukubona iinkcukacha. | Ukuqaphela indawo ekungqongileyo xa uhamba ngeenyawo, uqhuba imoto, okanye udlala imidlalo. |
Kutheni le nto le mbono ibalulekile kuthi?
Ubuchule bokubona bubaluleke kakhulu kwimisebenzi yethu yemihla ngemihla kunye nokhuseleko.
Khawuthelekelele uqhuba imoto. Ujonge ngqo phambili endleleni. Kodwa kungenxa yombono wakho ongaphandle kwendlela okwaziyo ukuqaphela izithuthi ezivela macala omabini kunye nabantu abawela indlela. Ngokufanayo, umdlali wekhilikithi, ngelixa egxile ekubetheni ibhola, unombono wokuba baphi abadlali basebaleni ngenxa yalo mbono. Kwakhona kungenxa yalo mbono okuncedayo ukuba ungangqubani nento ecaleni xa uhamba.
Zeziphi iindawo zeliso ezibonelela ngolu mbono?
Amehlo ethu afana nekhamera. Ngaphakathi kweliso, ngasemva, kukho isikrini esibizwa ngokuba yi-retina . Siqulethe izigidi zeeseli ezibamba ukukhanya. Imifanekiso yoko sikubonayo irekhodwa kwesi sikrini.
- Inxalenye ye-retina esembindini, nesinika umbono ocacileyo nocacileyo, ibizwa ngokuba yi-macula .
- Phakathi kwayo kukho indawo ebuthathaka kakhulu ebizwa ngokuba yi-fovea . Kulapho umbono wethu ophakathi uvela khona.
Ngoko ke umbono ojikelezayo uvela phi? Uvela kwindawo ephakathi ye-retina, i-macula, kunye neendawo ezingqongileyo. Nangona ezo ndawo zineeseli ezibona ukukhanya, azinakubonelela ngombono obukhali njenge-fovea. Yiyo loo nto izinto ezikungqongileyo zingacacanga njengokuba zinjalo embindini.
Kuza kwenzeka ntoni ukuba ulahlekelwa ngumbono wakho?
Le meko, apho ulahlekelwa khona kukubona okukungqongileyo uze ubone kuphela oko kuthe ngqo phambili, ibizwa ngokuba yi-tunnel vision . Khawuthelekelele usonga iphepha uze ujonge ihlabathi ngalo. Yiloo nto livakala ngayo. Awuboni nto macala omabini. Le inokuba yimeko eyingozi kakhulu, njengoko yenza kube nzima kakhulu ukwenza imisebenzi yemihla ngemihla, ingakumbi ukuqhuba imoto nokuhamba ngeenyawo.
Ngamanye amaxesha oku kunokuba yinto eyahlukileyo. Oko kukuthi, xa ubona izinto ezingaphandle, yindawo ojonge phambili kuphela ebonakala njengebala elimnyama. Siyibiza ngokuba yi- (Central Scotoma) .
Ngaba kuyinto eqhelekileyo ukuziva ngathi ubona izinto ngekona yeliso lakho?
Ngamanye amaxesha ungabona izinto ezifana neebhola ezincinci zentambo, amachaphaza amnyama, okanye iintambo zesigcawu zintanta phambi kwamehlo akho. Sizibiza ngokuba zii -Eye floaters . Njengoko sikhula, into efana nejeli engaphakathi kwamehlo ethu (i-Vitreous Humor) iyancipha kancinci. Emva koko, iziqwenga zayo ezincinci ziyaqhekeka zize zibonakale njengee-floaters. Ngamanye amaxesha, ungabona nokukhanya okufana nombane. Ezi azisoloko ziyingozi.
Nangona kunjalo, ukuba uhlala ubona izinto ezingekhoyo—njengeemilo, izibane, okanye imigca—yinto ekufuneka uyixhalabele.
- Mhlawumbi kukubona izinto ezingekhoyo .
- Okanye, isenokuba yimeko efana neCharles Bonnet syndrome , apho abantu abangaboni kakuhle babona izinto ezingekhoyo.
Ukuba usoloko ubona ezi mpawu, okanye ukuba ubona ezininzi kunangaphambili, kungcono ukubona ingcali yamehlo ngokukhawuleza uze uhlolwe amehlo akho. Kubaluleke kakhulu ukufumanisa ukuba kwenzeka ntoni kugqirha kunokuqikelela wedwa.
Uvavanya njani lo mbono?
Xa usiya kugqirha wamehlo, uza kujonga umbono wakho ongaphandle. Kukho uvavanyo olubizwa ngokuba yiVisual Field Test . Okufuneka ukwenze kukujonga kwindawo enye ngaphandle kokushukumisa intloko yakho. Emva koko baza kukubuza ukuba uyazibona na izibane ezivela kufutshane nawe. Olu luvavanyo olulula kakhulu, olungenabuhlungu. Olu luza kukuxelela ukuba ungabona kude kangakanani na kwaye ukuba uneengxaki zokubona.
Uhlala njani ubona kakuhle emehlweni akho?
Amehlo ethu ayinto exabisekileyo kakhulu, ngoko ke kukho izinto ezininzi esinokuzenza ukuze sigcine umbono wethu usempilweni.
- Ukuhlolwa kwamehlo rhoqo: Kubaluleke kakhulu ukuba amehlo akho ahlolwe ngugqirha wamehlo ubuncinane kanye ngonyaka, ingakumbi emva kweminyaka engama-40 ubudala.
- Indlela yokuphila enempilo: Kulungile kakhulu ukuzilolonga kakuhle nokutya ukutya okunesondlo (ingakumbi iziqhamo, imifuno kunye nentlanzi).
- Ukulawula ubunzima bomzimba: Izifo ezifana nesifo seswekile kunye noxinzelelo lwegazi oluphezulu olubangelwa kukutyeba kakhulu nazo zinokuchaphazela amehlo.
- Khusela amehlo akho: Nxiba iiglasi zelanga ezilungileyo xa uselanga. Oku kuya kukhusela amehlo akho kwimitha ye-UV eyingozi.
Ukuba uneengxaki zokubona, thetha nogqirha wakho ngazo. Ngamanye amaxesha, umthambo okhethekileyo wamehlo (unyango lokubona) unokunceda ukuphucula umbono wakho.
Umyalezo Wokuya Ekhaya
- Umbono ojikelezayo ubhekisa kwinto esiyibonayo emacaleni nakwesingqongileyo xa sijonga phambili ngaphandle kokushukumisa intloko yethu. Kubalulekile kukhuseleko lwethu lwemihla ngemihla.
- Lo mbono, nangona ungacacanga njengokuba ujonge phambili, ulungile kakhulu ekufumaneni intshukumo.
- Ukulahlekelwa ngumbono ongaphandle kwemithambo kubizwa ngokuba "ngumbono we-tunnel." Oku kungaba yimeko enzima kakhulu.
- Ukuba ubona izibane rhoqo phambi kwamehlo akho okanye ubona izinto ezingekhoyo, ngokuqinisekileyo bonana nogqirha wamehlo.
- Indlela yokuphila esempilweni kunye nokuhlolwa kwamehlo rhoqo yeyona ndlela ilungileyo yokukhusela amehlo akho axabisekileyo.
