Nakuba abantu bafuya amakati cishe eminyakeni engu-12 edlule, ubuhle obunoboya kuseyimpicabadala. Inkolelo yamanje yokuthi amakati anombono wasebusuku yengeza i-aura yemfihlakalo kuwo. Kodwa ingabe kuyiqiniso ukuthi amakati angabona ebumnyameni? Futhi uma kunjalo, kuhle kangakanani?

Ingabe amakati angabona ebumnyameni?

Ingabe amakati abona ebusuku? Akunjalo Empeleni. Nokho, angabona kahle kakhulu ekukhanyeni okufiphele, ikhono elanikeza okhokho bamakati afuywayo ithuba elingcono kunezisulu zabo. Njengoba uDokotela Wezilwane waseMelika echaza, ama-cornea amakhulu namakati amakati, acishe abe ngama-50% amakhulu kunabantu, avumela ukukhanya okwengeziwe emehlweni. Lokhu kukhanya okwengeziwe kubasiza ukuthi babone ebumnyameni.

Akuvamile ukuba kube nobumnyama obuphelele ezindaweni zokuhlala zabantu - kuhlale kunokukhanya okuncane okuvela endaweni ethile. Ngakho-ke, kubonakala sengathi amakati ane "izibuko zombono wasebusuku". Abanazo izibuko ezinjalo, kodwa kungase kubonakale kunjalo lapho isilwane esifuywayo esithambile sivuka phakathi nobusuku sinesicelo sokusinikeza ukuqabuleka. 

Eqinisweni, amakati awazona izilwane zasebusuku, kodwa ama-crepuscular: azingela lapho kuhwalala nasekuseni, okungukuthi, ngesikhathi sosuku lapho abaningi bezisulu zabo besebenza kakhulu. Lesi yisikhathi esiphelele sokuzingela.

Ukuvela kombono wasebusuku kumakati

Abacwaningi baseYunivesithi yaseCalifornia eBerkeley bathola ukuthi ukuma okuqondile komfundi ezilwaneni, kuhlanganise namakati, kuhlukanisa izilwane ezizingelayo. Ngokungafani nezilwane ososayensi abazibiza ngokuthi “amafolishi asebenzayo,” izilwane ezizingelayo zisebenza emini nasebusuku.

Okhokho bekati babengabazingeli ababodwa. Akukho okuningi okushintshile kusukela lapho, ngaphandle kokuthi izilwane ezifuywayo akudingeki zisebenze kanzima ukuze zizondle. 

Ososayensi baseNyuvesi yaseCalifornia, eBerkeley baphinde bathola ukuthi izilwane ezinabafundi abanjengama-slit zivamise ukuba ngaphansi phansi kunalezo ezineziyingi. Baphethe ngokuthi abafundi abame mpo basiza izilwane ezincane ukwahlulela ibanga lezilwane ezizingelayo, inzuzo leyo amakati amakhulu njengamahlosi namabhubesi angayidingi.

Amakati ngokumelene nabantu

Amakati abona kanjani ebumnyameni? Ingcono kakhulu kunabanikazi babo abayintandokazi. Abafundi abangabantu abayindilinga abakwazi ukuqhathanisa nabafundi be-vertical slit. Abafundi bekati babamba ukukhanya kwelanga okukhanyayo bese benwebeka ebumnyameni. Umbono we-felines unamandla kakhulu ngenxa yokuma kwesu nokunyakaza kwamehlo abo. Baphinde babone umhlaba kakhulu ngokumpunga, okulungele ukukhanya okufiphele.

“Amakati anekhono lokukhulisa amandla okukhanya okungena kuyi-retina ngesilinganiso esingu-135, uma kuqhathaniswa nokwanda okuphindwe kashumi kumuntu onomfundi oyindilinga,” kuchaza uDkt. York, i-New York Times. 

Ngamanye amazwi, mayelana nombono wasebusuku, abafundi abahlukanisiwe banikeza amakati ithuba elihle kakhulu kunabanikazi bawo, njengoba asabela kahle kakhulu ekukhanyeni okushaya i-retina. Ingabe amakati angabona ebumnyameni obuphelele? Cha.

Nokho, abantu banenzuzo eyodwa yokubuka ngaphezu kwabangane babo abanoboya: Abantu banokubona okungcono, noma ukucaca, kunamakati, ngokusho kweBusiness Insider. 

Abantu bangabona ngokucacile kunezilwane zabo ezifuywayo, kodwa amakati anqoba ngokubona ebusuku. Ukuhlanganiswa kwamakhono okubukwayo omnikazi kanye nekati lakhe kubenza babe yiqembu eliphelele.
