Njengamanje, amalambu omgwaqo abomvu, aluhlaza okotshani kanye naphuzi. Okubomvu kusho ukuthi yeka, okuluhlaza kusho ukuthi hamba, okuphuzi kusho ukuthi linda (okungukuthi lungiselela). Kodwa kudala, kwakunemibala emibili kuphela: obomvu noluhlaza okotshani. Njengoba inqubomgomo yokuguqulwa kwethrafikhi yayiba ngcono kakhulu, kwanezelwa omunye umbala kamuva, ophuzi; Kwabe sekwengezwa omunye umbala. Ngaphezu kwalokho, ukwanda kombala kuhlobene eduze nokusabela kwengqondo kwabantu kanye nesakhiwo sokubona.
I-retina yomuntu iqukethe amaseli e-photoreceptor amise okwenduku kanye nezinhlobo ezintathu zamaseli e-photoreceptor amise okwenduku. Amaseli e-photoreceptor amise okwenduku azwela kakhulu ekukhanyeni okuphuzi, kuyilapho izinhlobo ezintathu zamaseli e-photoreceptor amise okwenduku ezwela ekukhanyeni okubomvu, ekukhanyeni okuluhlaza kanye nasekukhanyeni okuluhlaza okwesibhakabhaka ngokulandelana. Ngaphezu kwalokho, isakhiwo sokubona sabantu senza kube lula ngabantu ukuhlukanisa phakathi kokubomvu nokuluhlaza. Nakuba okuphuzi nokuluhlaza okwesibhakabhaka kungenzima ukuhlukanisa, ngoba amaseli e-photoreceptor enhlamvini yeso awazweli kakhulu ekukhanyeni okuluhlaza okwesibhakabhaka, okubomvu nokuluhlaza okwesibhakabhaka kukhethwa njengemibala yesibani.
Ngokuphathelene nomthombo wombala wethrafikhi, kukhona nesizathu esiqinile, okungukuthi, ngokwesimiso se-physical optics, ukukhanya okubomvu kunobude obude kakhulu kanye nokudluliselwa okunamandla, okukhanga kakhulu kunezinye izimpawu. Ngakho-ke, kusethwe njengombala wesignali yethrafikhi yethrafikhi. Ngokuphathelene nokusetshenziswa koluhlaza njengombala wesignali yethrafikhi, kungenxa yokuthi umehluko phakathi koluhlaza okotshani nokubomvu mkhulu futhi kulula ukuwuhlukanisa, futhi i-coefficient ye-color blind yale mibala emibili iphansi.
Ngaphezu kwalokho, kunezinye izici ngaphandle kwezizathu ezingenhla. Ngenxa yokuthi umbala ngokwawo unokubaluleka okungokomfanekiso, incazelo yombala ngamunye inezimpawu zayo. Isibonelo, obomvu unikeza abantu isifiso esinamandla noma umuzwa ojulile, kulandelwe ophuzi. Kwenza abantu bazizwe beqaphile. Ngakho-ke, kungabekwa njengemibala yezibane zomgwaqo ezibomvu neziphuzi enencazelo yokuvimbela ithrafikhi nengozi. Okuluhlaza kusho ubumnene nokuthula.
Futhi okuluhlaza kunomthelela othile wokunciphisa ukukhathala kwamehlo. Uma ufunda izincwadi noma udlala ikhompyutha isikhathi eside, amehlo akho azozizwa ekhathele noma enciphile kancane. Ngalesi sikhathi, uma uphendulela amehlo akho ezitshalweni noma ezintweni eziluhlaza, amehlo akho azoba nomuzwa wenduduzo ongalindelekile. Ngakho-ke, kufanelekile ukusebenzisa okuluhlaza njengombala wesignali yethrafikhi onenani lomgwaqo.
Njengoba kushiwo ngenhla, umbala wesignali yomgwaqo wokuqala awubekwanga ngokungahleliwe, futhi kunesizathu esithile. Ngakho-ke, abantu basebenzisa obomvu (omele ingozi), ophuzi (omele isexwayiso sasekuqaleni) kanye nohlaza (omele ukuphepha) njengemibala yesignali yomgwaqo. Manje iyaqhubeka nokusebenzisa nokuqhubekela phambili ohlelweni olungcono lwe-oda lomgwaqo.
