Ubumpumputhe bombala kuvame ukubangelwa isici se-retinal, futhi kuyinkinga yezakhi zofuzo yemvelaphi. Uma ucabanga ukuthi ingane yakho inenkinga yokuhlukanisa imibala, ebomvu kusuka eluhlaza noma eluhlaza okwesibhakabhaka kusuka ophuzi, ingahle ibe yimpumputhe yombala.
Umfana oyedwa kwabangu-12, nentombazane eyodwa kwezingu-1, nokuthi amadoda maningi amathuba okuba angaboni kahle, wonke amadoda azuza i-X chromosome azohlushwa yile nkinga yokubona. Ngaphezu kwalokho, ubumpumputhe bombala bungaba nokuthweswa iziqu okuhlukile, futhi ukuthola ukuthi hlobo luni, ukuskena kombono wombala kufanele kwenziwe.
Izinyathelo okufanele uzilandele ukuthola uma ingane yakho ingaboni kahle
Sikunikeza amathiphu wokuthola uma ingane yakho ingaboni kahle, ngokwesibonelo lapho eqala ukufunda imibala, kufanele uqaphele. Ingane yakho ingahle ididanise igama lombala, noma kungenzeka ukuthi ayihlukanisi kahle phakathi kwayo. Amaphesenti angamashumi ayisishiyagalolunye wezingane eziyizimpumputhe ezinombala abuthakathaka ngokubomvu noma ngokuluhlaza, okungukuthi, awahlukanisi phakathi kwazo.
Enye indlela yokuthola ukuthi ingane yakho ayiboni ngombala yini dlala naye ngemibala yezithelo bese umbuza: leli peya linombala onjani? Unjani umbala wale apula? Ngale ndlela uzohlola, udlale, futhi lapho omncane ekhululeke ngokwengeziwe uma ephambanisa imibala ngempela.
Futhi ngaphezu kwakho konke, uma usola ukuthi ingane yakho ayiboni ngombala, into engcono kakhulu ongayenza iya kudokotela wezifo zamehlo ukuze ukwazi ukuqinisekisa ukuxilongwa nezinga lokungaboni kombala ngokuhlolwa okuhlukile. Lokhu kuzokunikeza imihlahlandlela ehlukile yengane yakho ukuze iphile nalesi sifo, ngoba alikho ikhambi.
Izindlela zokuskena ngombala wombala
Kukhona eziningana izindlela zokuhlola umbono yemibala, nodokotela wezifo zamehlo noma wena ekhaya, ungakwenza. Indlela elula yokuqinisekisa umbono ojwayelekile wombala yi- Ishihara ukuhlolwa. Ukuhlolwa kweFarnsworth, okuyinkimbinkimbi ngokwengeziwe, futhi kuvumela ukucwasa uhlobo lombala oluthintekile namandla alo. Sichaza kafushane ukuthi aqukethe ini.
Isivivinyo se-Isihara si indlela esheshayo nelula yokukhomba izinombolo ezifihliwe futhi ipendwe ngemibala ehlukile kunemibuthano equkethe, njengale oyibona esithombeni. Ngakho-ke kubalulekile ukuthi izingane zazi izinombolo. Inombolo 74 yilokho abafana namantombazane abanombono ojwayelekile abakubonayo, kuyilapho labo abane-dyschromatopsia noma i-trichromacia bebona ama-21 nezingane ezine-achromatopsia ababoni lutho.
El Ukuhlolwa kweFarnsworth kuthola izinhlobo ezahlukahlukene zobumpumputhe bombala phakathi kwamaqembu ombala ahlukene ayishumi nanhlanu. Isivivinyo senziwe ngamaphilisi ayi-100 anemibala ehlukene futhi umthunzi ngamunye wehluka komunye ngokuhluka okuncane kancane. Ngaphezu kwalokho, isivivinyo siqukethe amathreyi ama-4 anamaphilisi ayi-25, kanti ithreyi ngalinye limele uhla lwebala lombala. Isivivinyo senziwa ngesikhathi esiphezulu semizuzu engu-8
Ungayisiza kanjani ingane yakho engaboni kahle
Izingane cishe azizivezi obala izimpawu zesifo se-ophthalmological, noma kunalokho azazi kahle ukuthi ziyini. I- ukutholwa kwangaphambi kokungaboni kahle kombala kuzosisiza ukulandela imihlahlandlela ethile, ngoba yize ukungaboni kahle kungesona isifo esibi kungadala ubunzima ezinganeni.
Isibonelo, lapho indlela ye- ukufunda ezikoleni zasenkulisa noma ezifundweni ezithile ngokuya ngombala, abantu abayizimpumputhe ezinemibala bazokwenza ngokungafani nezingane ezinombono ojwayelekile. Ngakho-ke, kubalulekile ukukhuluma nothisha ngalesi simo, ukwenza ukuvumelana ngokwanele kwezifundo. Kunezincwadi ezifundelwe izingane ezinemibala engaboni.
Umbala wobumpumputhe ngokuvamile akubangeli ukukhubazeka okukhubazekayo nokwazisayo. Lezi zingane cishe zihlala zifundiswa imibala ngokuzihlanganisa nezimpawu. Njengamanje, izingilazi ziyakhiwa futhi zihlolwe ukulungisa umbono ezimweni ezithile zokungaboni ngombala. Siyethemba ukuthi sikusizile ukuthi usiqonde kangcono isimo sengane yakho.
