Siza ufingqe izimbangela nokwelashwa kokungaboni imibala okukhulunywe ngakho kulesi siqephu?
Context:Imbangela evame kakhulu yobumpumputhe bokungawaboni imibala inkinga esiyizuze njengefa noma ukuhluka kokusebenza kohlobo olulodwa noma ngaphezulu lwamangqamuzana e-cone kuyi-retina, okuyiwona alinganiselayo ekuboneni imibala. Uhlobo oluvame kakhulu lubangelwa isifo sofuzo esibizwa ngokuthi i-congenital red-green color blindness. Abesilisa banamathuba amaningi okuthi babe izimpumputhe ngenxa yemibala kunabesifazane, ngoba izakhi zofuzo ezibangela izinhlobo ezivame kakhulu zobumpumputhe ngenxa yemibala zise-X chromosome. Izinsikazi ezingeyona i-colorblind zingaba nezakhi zofuzo zokungaboni imibala futhi zidlulisele lezi zofuzo ezinganeni zazo. Ukungaboni imibala kungabangelwa ukulimala kwamehlo, izinzwa zokubona noma izingxenye zobuchopho. Ukuhlolwa kokungaboni imibala kuvame ukwenziwa ngokuhlolwa kombala kwe-Ishihara.  Ayikho indlela yokwelapha ukungaboni imibala. Ukuxilongwa kungase kuvumele umuntu, noma abazali/othisha bakhe ukuba babhekane nesimo. Izibuko ezikhethekile ezinjengezibuko ze-EnChroma noma ama-X-chrom contact lens zingase zibasize abantu abanobumpumputhe obomvu-luhlaza kwezinye izinto ezihlobene nombala, kodwa azibaniki abazigqokayo umbono ovamile wemibala". Izinhlelo zokusebenza zeselula zingasiza abantu ukuba babone imibala".
Imbangela evame kakhulu yobumpumputhe bokungaboni imibala isifo sofuzo. Amadoda anamathuba amaningi okuba abe yizimpumputhe ngenxa yemibala kunabesifazane, ngoba izakhi zofuzo ezibangela lokhu zikhona kuyi-X chromosome. Abesifazane abangayiboni imibala bangase babe nezakhi zofuzo ezibangela ubumpumputhe bebala. Noma yiluphi uhlobo lokulimala ngokomzimba noma ngamakhemikhali esweni, ebuchosheni noma ebuchosheni nakho kungaholela kulokhu.  Ayikho indlela yokwelapha ukungaboni imibala. Abantu abathintekile bangavumelana nesimo noma basebenzise izibuko noma amalensi akhethekile angasiza abantu abanobumpumputhe obubomvu noluhlaza ngokwezinga elithile. Kukhona nezinhlelo zokusebenza zeselula ezisiza ekuboneni imibala.
