Noma kukhathaza nje ukukhononda ngazibonela ngokwami ​​mayelana ekupheleni play (ngenxa yokuthi bese kumnyama) izolo ebusuku, kungazelelwe umcabango lafika kimi - nge ibhola elibomvu futhi pitch oluhlaza, can red-green col­our-blind people play crick­et successfully?

Angikwazi ukucabanga ukuthi kungani abaphosayo bezokhishwa kabi kakhulu, kepha ukushaya nokufaka enkundleni kungaba nzima kakhulu. Ngesikrini sokubona noma yibuphi ubunzima kufanele bancishiswe, futhi ukubanjwa okuningi enkundleni kunesibhakabhaka njengesizinda sangemuva, kepha kusazoba nezikhathi lapho ibhola kufanele kube nzima kakhulu ukulikhetha. Ngakho-ke, baningi abadlali abasezingeni eliphakeme kakhulu abangaboni?  Kubonakala sengathi abase-Australia banakho ungishaye kuso, futhi sengivele ngenze okuxhunyelelwe kanzima ukunikeza impendulo kulo mbuzo. Isiphetho: emazingeni amaningi abantu abangaboni imibala baboniswa ngokuhambisana nenombolo yabo kubantu (azungeze 10%), kepha emazingeni aphakeme kakhulu akukho bantu abangaboni kahle nhlobo (UBill Ponsford angahle abe ngumthetho. Le nganekwane yase-Aussie yadlala 29 test okufanayo ngesilinganiso se- 48).  Kubukeka sengathi emazingeni aphakeme kakhulu ukungaboni umbala kuyisithiyo esikhulu. Kuwo wonke amazinga, Abadlali abanobumpumputhe bebala bakuthola kunzima ukubona ibhola linqamula otshanini futhi bathambekele ekugwemeni izikhundla eziphakathi nendawo nokujula - okaputeni bayabona!  Olunye ucwaningo lukhombisile ukuthi abashayayo abangaboni imibala abathinteki kakhulu, isibonelo ukudlala ngokulingene nebhola elimhlophe akuhlukile kunesilinganiso sabo nebhola elibomvu.

Ngakho, kubonakala sengathi ngenkathi singeke sikwazi ukuthola abadlali abaningi bokuhlola abangaboni imibala, uma ungaboni kahle futhi ufuna ukwehlela ekilabhini lendawo ngempelasonto, hamba babhajwe!  Ungatshala futhi imali ngababili Oxy-Iso izibuko, okusobala ukuthi kuthuthukisa ubomvu nemifino!

I kumelwe futhi athi, kunezimo ezahlukahlukene ezawela ngaphansi kwegama lengubo "red-green color-blind", okuyi-protanopia, deuteranopia, pranomaly, futhi deuteranomaly. Uma ucabanga ukuthi ungaba nesinye salezi zimo kodwa ungatholakali, ngicela ukhulume nodokotela wakho (ngaphambi noma ngemuva komdlalo) - siyiwebhusayithi yekhilikithi hhayi eyezokwelapha!

Ucabanga ukuthi senze uphuthelwe into? Sazise ngokukhuluma ngezansi. Uma ungathanda ukuba ubhalise sicela usebenzise ubhalisele isixhumanisi on the imenyu at ilungelo phezulu. Ungase futhi wabelane le nabangani bakho ngokusebenzisa links social ngezansi. cheers.

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.
