Njengoko uyazi, iikati zasekhaya zilwanyana zobusuku, umbono wazo ebumnyameni uhlala phezu kwabantu ngaphezu kwamaxesha angama-10. Konke oko kunokwenzeka ngenxa yobuninzi beentonga phezu kwamaconsi kwi-retina yeso. Ngokungafani nabantu, iliso lekati liyabona iincwadana zamanani ebumnyameni ngokugqithiseleyo, "ukukhanyisa" ukucaciswa kwindlela yokujonga kweso sixhobo sombono. Ngaloo ndlela, ebumnyameni, endaweni yezithulu abangezithulu, iikati zibona imvelaphi egciniweyo ngamanani acacileyo. Kodwa akuzona zonke iikati ezinikwe amandla okubona kakuhle ebumnyameni - abameli abakhulu beqela ebantwini beengonyama kunye nama-tigers, umzekelo, kubonwa ngcono emini ngenxa yobuninzi beetonki, eziguqula lezi ziqhwaba kubazingeli basuku ngaphandle kobusuku.
Ukubona kwamakati , kunye nendlela abayibona ngayo, inqoba phezu komntu kwimeko xa ifika kwirejista yokubukela. Iliso lekati liyabanjwa
20% ngaphezulu komfanekiso kumacala - kunokuba asikho idivaysi efanelekileyo yokujonga ixhoba?
Kodwa ungacingi ukuba iliso lomntu lilahlekelwa yikati kuzo zonke iindawo. Ngoko, iikati zibona kakubi izinto eziphantsi kwempumlo yazo kwaye zikude kumitha engama-6 ukuya kude. Kwaye ukuba ngokuchongwa kweenkcukacha eziqhelekileyo kwiikati kunokunceda ukujamelana neqondo elimnandi lokunuka, ngoko umfanekiso ekude kwilwanyana akulula ukuwuqwalasela, ngakumbi ukuba izinto ezingenayo ngaphandle kokunyakaza.
Yimiphi imibala ikati ibona?
Umbuzo, njengokuba umhlaba wekati ubona, unomntu onomdla ixesha elide. Ekuqaleni kwakukholelwa kakhulu ukuba babona imibala emhlophe kuphela, kodwa eqinisweni akukho konke - isilwanyana esilulayo sibona iphalethi embala phambi kwayo, nangona kungekho kuyo yonke inkazimulo ebonwa ngumntu. Ihlabathi phambi kwamehlo enkati kunjengekugqumeni, oku kuthetha ukuba yonke imibala inokugqithisa ngakumbi kunokuba ikhona. Ukongeza, ngenxa yezinto ezikhethiweyo zesakhiwo se-receptor zixhobo kwi-retina, iikati ngokuqhelekileyo ayiboni umehluko phakathi obomvu obomvu, ophuzi kunye nolunxwemeni, obushushu obushushu, obuluhlaza kunye nohlaza okwesibhakabhaka.
