Sonke sinamehlo amahle futhi abanye bethu banezinkinga zokubona kanye nokubukwa kwekhwalithi, kuyilapho abanye bengabona yonke into ngokucacile ngisho nasebudaleni babo. Into evamile ukuthi sonke siyakwazi ukubona into kuze kufike emkhawulweni othile.
UVeronica Seider, ongaphezu kwamandla omuntu onamandla amakhulu, wazalelwa eNtshonalanga Jalimane ngo-1951. UVeronica, njenganoma iyiphi enye ingane yaseJalimane, waya esikoleni wagcina ebhalise eStuttgart University eNtshonalanga Jalimane.
U-Seider wephule umqondo oyisisekelo womkhawulo wokubona komuntu, ngoKhozi lwakhe olunjengamehlo “angaphezu kwawomuntu”. Ukusho ukuthi, uVeronica wayenamehlo ane- ikhono elingaphezu komuntu okwamsiza ukuthi abone futhi akhombe umuntu ekude nebanga.
U-Veronica Seider - owesifazane owaba nombono omuhle kakhulu emhlabeni
Amakhono kaVeronica Seider aqale aqashelwa ngumphakathi jikelele ngenkathi esafunda. Ngo-Okthoba 1972, i-University of Stuttgart yayiqhuba izivivinyo zombono kubafundi bazo. Le nqubo ifaka phakathi ukuhlolwa kwamandla wokuxazulula iso lomuntu.
Ngemva kokuhlolwa okubukwayo, inyuvesi yabika ukuthi omunye wabafundi bayo ogama lakhe linguVeronica Seider unamehlo angavamile futhi uyakwazi ukubona futhi akhombe umuntu oqhele ngekhilomitha, okusho ukuthi iqhele ngamakhilomitha angu-1! Lokhu kungcono izikhathi ezingaba ngu-1.6 kunomuntu oyedwa ojwayelekile ongabonwa, futhi umbono omuhle kakhulu osabikiwe. USeider wayeneminyaka engu-20 ubudala ngesikhathi sokuhlolwa okubukwayo.
I-Visual acuity emehlweni omuntu ajwayelekile ingu-20/20, kanti endabeni kaSeider, yayicishe ibe ngu-20/2. Ngakho-ke, wayekwazi ukubona kalula futhi ngokushesha abantu abaqhelelene nebanga eliyikhilomitha elilodwa futhi wayekwazi nokubala nebanga elilinganiselwe ukusuka kuye. Kuphinde kwabikwa ukuthi ukwazile nokuhlonza into esezingeni elincane. Ngekhono lakhe lokubona elingaphezu komuntu, uVeronica Seider wathola igama lakhe eGuinness World Record Book ngo-1972.
Ngaphandle kwalokho, umbono kaVeronica ufaniswa nowezibonakude. Uqhube wathi uyakwazi ukubona imibala eyakha uhlaka kumabonakude onemibala.
Noma yimuphi umbala, ngokwesayensi, wakhiwe imibala emithathu eyisisekelo noma eyinhloko: obomvu, oluhlaza okwesibhakabhaka, noluhlaza. Umbala ngamunye ubonwa ngamehlo avamile njengenhlanganisela yemibala eyinhloko ngamanani ahlukahlukene. Abantu abayizimpumputhe, ngeshwa, abanayo indlela yokwazi ukuthi babona umbala onjani.
Ngakolunye uhlangothi, uVeronica Seider, wayekwazi ukubona imibala ngokwezakhi zayo: obomvu, oluhlaza okwesibhakabhaka, noluhlaza. Kuyamangaza ngempela. Nakuba uVeronica wayenamehlo angaphezu kwawomuntu, kubhekwa njengokungavamile kofuzo (kungcono ukuba nokungajwayelekile okunjalo).
Siyini isizathu sesayensi esibangela ukuthi u-Veronica Seider abone iso lokhozi?
Ku-25 cm, ikhono elijwayelekile lokuxazulula iso lehlela kuma-microns ayi-100, noma ku-0.0003 we-radian. Imicron eyodwa ilingana nenkulungwane yemilimitha, ngakho-ke ama-microns ayi-100 alingana cishe nengxenye eyodwa kweziyishumi zemilimitha, okuncane kakhulu. Lokho kucishe kufane nocashazi elisephepheni.
Kepha iso elijwayelekile lingakwazi ukubona izinto ezincane kakhulu, inqobo nje uma into ikhanya ngokwanele, futhi kunezimo ezifanele zemvelo. Esinye sezibonelo ezinjalo inkanyezi ekhanyayo ehlala kude izigidigidi zeminyaka yokukhanya. Ezinye izinkanyezi, noma eminye imithombo yokukhanya ekhanyayo engamamitha ayi-3 kuya kwangu-4 kuphela ngaphesheya kungabonakala ngeso elijwayelekile. Manje, lokho kuncane.
Amakhono athuthukisiwe kaVeronica Seider
Ikhono lokubuka likaVeronica Seider lithathwa njengemfihlakalo yomuntu ehlukile. Ukubona kwakhe ngamandla kwamenza wakwazi ukubhala incwadi enamakhasi ayi-10 ngemuva kwesitembu bese eyifunda kahle.
UVeronica uphinde wakufakazela lokhu ngokudabula isiqeshana sephepha elilingana ncamashi nocikicane lwakhe. Wabe esebhala ngokucophelela amavesi angama-20 enkondlo akuyo. UVeronica Seider, ushone ngoNovemba 22, 2013, wayeneminyaka engama-62 ngesikhathi sokushona kwakhe. Noma esemdala, umbono kaVeronica wawukholakala ukuthi uphakeme kakhulu kunomunye umuntu.
Yize enekhono elingaphezu kwelomuntu, uVeronica waphokophela isifiso sakhe sokuba udokotela wamazinyo eNtshonalanga Jalimane. Kanye nomsebenzi wakhe awukhethayo, uVeronica uncamela ukuhlala njengomuntu ojwayelekile empilweni ejwayelekile. Ngenxa yalokho, wayehlala enquma ukuhlala engaziwa.
Kungenzeka yini namuhla ukuba namehlo "angaphezu komuntu" njengoVeronica Seider ngokuhlinzwa okuthuthukile kwamehlo?
Impendulo ithi "Yebo" no "Cha" zombili. Uma ufuna umbono ohlukile ngokwemvelo ngendlela ephilayo njengoVeronica Seider, lapho-ke akunakwenzeka kusukela manje. Amandla okubuka womuntu anqunyelwe inani le- izinduku nezigaxa lawo empeleni angamaseli we-photoreceptor athulwe kungqimba olungaphandle lwe-retina yethu.
Izinduku zibhekele umbono emazingeni aphansi okukhanya (umbono we-scotopic). Awaxhumanisi ukubona kombala, futhi anendawo ephansi yokuqina. Izigaxa ziyasebenza emazingeni aphezulu okukhanya (umbono we-photopic), iyakwazi ukubona ngombala futhi inesibopho sokuqina kwendawo okuphezulu. Futhi awukwazi ukwandisa noma wehlise inani lala ma-photoreceptor nganoma yikuphi ukuhlinzwa kwamehlo.
Kepha kunenkampani ebizwa, Okuningi ngo-Ocumetics Technology Corp. lokho kukhulisa ilensi ye-bionic okungenzeka ukuthi izokwenza lokho esikufunayo ncamashi. Uma ungabona nje iwashi ngezinyawo eziyi-10, nge-Bionic Lens, uzoyibona kusuka ezinyaweni ezingama-30!
Umuntu onombono ongu-20/20 empeleni uzokwazi ukufunda okulotshwe ngamamitha angama-60 futhi kuzocaca kahle. Lokho kungaphezu kobude benkantolo yebhasikidi. Ubukhali nokucaca kombono ngeke kusenzeka njengangaphambili.
Ilensi ye-bionic enika indoda amandla ngalo mbono ongaphezu komuntu ibizwa nge I-Ocumetics Bionic Lens, futhi yathuthukiswa nguDkt Garth Webb, udokotela wamehlo waseCanada, owayebheke ukukhulisa ukubona komuntu kungakhathaliseki ubudala noma impilo.
Inqubo ifana nokuhlinzwa kwe-cataract. Kubandakanya ukukhipha ilensi yakho yoqobo bese uyifaka esikhundleni se-Ocumetics 'Bionic Lens, eligoqwe laba yisiponji esisetshenzisweni sikasawoti futhi sijojowe ngqo esweni lakho.
I-Ocumetics 'Bionic Lens njengamanje iyahlolwa imitholampilo ngenhloso yokugcina yokuvunywa emtholampilo. Kusukela ngo-Ephreli 2019, baguqule ngempumelelo ukwakheka kwe-Bionic Lens yokukhiqiza ngobuningi.
Ukubona ngokucacile kuwo wonke amabanga ngaphandle kwezingilazi noma ama-contact lens kuyisifiso sabaningi bethu, futhi lokho kuba yinto engokoqobo ngokushesha.
