1isihara umbala oyimfamaNgaba abantu umbala-iimfama bomvu-luhlaza ukudlala iqakamba?

Ngelixa bayakrokra ngokwam ngayo ekupheleni komdlalo (ngenxa ekukhanyeni) izolo ebusuku, a Kwathi qatha kum - ngebhola ebomvu kunye pitch eluhlaza, can red-green col­our-blind people play crick­et successfully?

Andikwazi ukucinga ukuba kutheni izitya ezinokuthi zenziwe kakubi, kodwa bekwenza nokuganga kungaba nzima kakhulu. Nge emehlweni-screen naziphi na iingxaki kufuneka incitshiswe, kunye ezininzi iintlanzi entsimini babe isibhakabhaka nje umzobo, kodwa khona kuya kubakho amaxesha apho ibhola kufuneka kube nzima ngakumbi ukuba zikhethe. ke, zininzi abadlali kwi eliphezulu kwinqanaba lombala-blind?  Kubonakala ukuba le Australia wandibetha kuyo, yaye sele kwenziwe le sihlume nzima ukuba awuphendule lo mbuzo. isiphetho: kumanqanaba uninzi lwabantu umbala-iimfama zimelwe ngokuhambelana inani labo labantu (ngeenxa 10%), kodwa kumanqanaba aphezulu kakhulu kukho phantse akukho bantu umbala-abangaboniyo kwaphela (Bill Ponsford inokuba Kwimeko ongasetyenziswayo kuyo lo mgaqo. Le legend Aussie wadlala 29 test elithelekiseka kwi-avareji 48).  Kubonakala ukuba kumanqanaba aphezulu kakhulu ukuba umbala-iimfama sisithintelo ebalulekileyo. Kuwo onke amanqanaba, abadlali ngemibala-nangobumfama bakufumanisa kunzima ukubona ibhola liphela ingca, isalusa ukuphepha phakathi kunye nezikhundla ukuganga olunzulu - abathetheli phawula!  Ezinye izifundo lubonise ukuba Abaqhokri imibala-blind azichaphazeleki kakhulu, umzekelo ukuba i-avareji okudlala kunye ibhola emhlophe eyahlukileyo akukho ukusuka avareji babo ibhola ebomvu.

Ngoko ke, kubonakala ukuba ngeli xesha na ukuba kungenzeka ukufumana abadlali abaninzi uvavanyo ngamazwe umbala-blind, xa sele umbala-iimfama kwaye ufuna ukufumana kwiklabhu yasekuhlaleni-veki kwi, hamba uze ubambezeleke!  Kananjalo imali iperi Oxy-Suomen iiglasi, leyo kuthiwa ukuphucula Imibala nemifuno!

Mandithathe kwakhona ndithi, kukho iimeko ezininzi ezahlukeneyo eziwela phantsi kwegama ngengubo "bomvu-luhlaza lombala-blind", angala protanopia, deuteranopia, protanomaly, kunye deuteranomaly. Ukuba ucinga ukuba ungafika unayo enye yezi meko ke ndingenalo waxilongwa, nceda thetha nogqirha wakho (phambi okanye emva komdlalo) - siyaqhubeka iwebhusayithi leqakamba hayi ezonyango!

Nceda sithumelele iingcinga zakho egqabaza ngezantsi! Ukuba ungathanda ukuba uzibophelele nceda sebenzisa i rhuma ikhonkco kwi menu entla kwasekunene. Unga kwakhona ukwabelana oku nabahlobo bakho ngokusebenzisa amakhonkco zentlalo ngezantsi. Masinwabe.

The pink ball appears grey/blue in red/green defi­cient vis­ion, depend­ing on its sever­ity. I did a sim­u­la­tion with col­our blind­ness soft­ware where the ball almost dis­ap­peared against a blue sky. The depth of blue also var­ies through­out the world. The RAF real­ised this dur­ing the war when they needed dif­fer­ent blue cam­ou­flage shades depend­ing where their recon­nais­sance Spit­fires were oper­at­ing. They also found that in cer­tain even­ing and morn­ing light the sky can take on a dis­tinct pink tinge, and in these cir­cum­stances painted the Spit­fires pink, so there could be prob­lems for crick­eters with nor­mal vis­ion pick­ing up a pink ball in the sky in cer­tain light. White balls are OK, and yel­low, but not orange for same reas­on as red.
