Ukuqonda Ukubona Imibala Ebuthakathaka: Izimpawu, Izimbangela, Nokwelashwa

Ukubona imibala ebuthakathaka, okuvamile kubizwa ngokuthi ukuba yimpumputhe yemibala, kuyisimo lapho unokukhuluphala khona ukubona noma ukuhlukanisa imibala ethile. Lokhu kwenzeka lapho amaseli azinzayo ekukhanyeni emehlweni akho engasebenzi kahle ukuthola imibala ethile noma umehluko wemibala.

Cishe owesilisa oyedwa kwabayishumi nambili nowesifazane oyedwa kwabayikhulu namabili unawo uhlobo oluthile lokuntuleka kokubona imibala. Abantu abaningi abanesimo esinjalo bangabona imibala, kodwa bangadida amashadi athile noma bawabone ngendlela ehlukile kunabanye.

Iyini Imibala Ebuthakathaka?

Ukubona imibala ebuthakathaka kwenzeka lapho amaseli e-cone e-retina yakho engasebenzi kahle. I-retina yakho inamaseli amathathu e-cone ahlola ubude be-wavelengths obumhlophe, oluhlaza, noluluhlaza okwesibhakabhaka.

Lapho uhlobo olulodwa noma ngaphezulu lwamaseli e-cone lubuyeke, lungasebenzi kahle, noma luthole imibala ngendlela ehlukile, uhlangabezana nezinkinga zokubona imibala. Lokhu kungaba ukukhuluphala okuncane ukuhlukanisa imibala efanayo kuya ekungakwazi ukubona imibala ethile nhlobo.

Abantu abaningi abane-ukubona imibala ebuthakathaka bazalwa benalesimo futhi bangase bangazi ukuthi babona imibala ngendlela ehlukile kuze kube yilapho bevivinywa. Isimo sivamise ukuba siqine ngokuphila futhi alubi kakhulu ngokuhamba kwesikhathi.

Ziphi Izimpawu Zokubona Imibala Ebuthakathaka?
