Nayiphi na umntu oye wafumana isilwanyana esinezilwanyana ezine-shaggy, esondela rhoqo kwinqaba yakhe ehlakaniphile, ezinikezele inja. Baqonda phantse yonke into, babonise uvuyo okanye intlungu, kodwa abakwazi ukuthetha nantoni na inkosi. Ziziphi iinkqubo ezenzeka entloko? Inja ibujonga njani ihlabathi lethu elisijikelezayo? Ukuba ufunda le nqaku, kuthetha ukuba unomdla kule mibuzo ngaphezulu kweyodwa. Iingcali zenzululwazi zide zifundela izinja, kunye nezinye zeenkcukacha ezifunyenwe ngenxa yeziphumo ezide, kuba abantu abaninzi baya kuba bengalindelekanga.
Iyiphi imbala ebonakalayo inja?
Ngoku kutshanje, saqinisekiswa ukuba izinja zibona ihlabathi njengomnyama nomhlophe. Le ngcamango yayiyiphutha. Umbono wembala wezilwanyana zethu ezifuywayo zihlukile kubantu, kodwa azinako ukubizwa ngokuba yimbala-imfama. Kuphela nje ukuba ezi zilwanyana zinesakhiwo esithile samehlo. Kwi-retina kukho iinqununu ezikhethekileyo ezijongene nobuzwe bombala. Isidalwa ngasinye esiphilayo siyimfuneko. Abo babona umbala obomvu, abahlobo bethu abaneemilenze abane. Umthunzi ohlaza okomhlaza obomvu obunomhlaza obomvu, bangadideka. Kwaye ibhokhwe eluhlaza okwesibhakabhaka yezinja ngokubanzi ibonakala ngathi ishidi elimhlophe.
Ngaba izinja zibona ebumnyameni?
Iingcali zezilwanyana zethu ezineemilenze ezinezikhwebu zibhekiswa njengezilwanyana ezidlulileyo, ezijoliswe kakuhle emini nasemini ebumnyama. Izibonda ezikhanyayo ziphucuke ngakumbi kubo kunabantu. Oku kuvumela izinja ukuba zihlukanise ngakumbi iimpawu zegrey. Emva kokushona kwelanga, ininzi yethu ayiboni nantoni ngaphandle kwelanga, kodwa izinja ziyaqhubeka ziziva zikhululekile. Kuyabonakala ukuba ebusuku amehlo abo angama-3 okanye amaxesha amane angcono kunabantu. I-retina yamehlo ethu abafundi ihlukaniswe ngamacandelo. Icandelo elincinane lithatha ukukhanya okungaphezulu, okwenza umnikazi walo abone kakuhle ngokukhanya okukhulu. Kwaye icandelo eliphezulu lilungiselelwe ukuqinisa umbono ebusuku.
Izinja zizilwanyana, kwaye kubo kubaluleke kakhulu ukucacisa into yokuzingela nangaliphi ixesha lomhla. Bokuba bhetele bathabathe iinjongo ezihambelayo kunento ehleliweyo. Ezi zilwanyana ziyakwazi ukubona ukuhamba kwakho kumgama wama-800-900 wamitha. Kodwa ukuba ithagethi ifihliweyo, umlindi onobuchopho obune-4 uya kuphawula ngamamitha kuphela ukusuka ku-600. Yingakho umntu ophunyukileyo uza kuqonda ngokukhawuleza inja njengento yokuzingela.
Izinja zibona njani kwibala elikufutshane? Kuye kwabonakaliswa ngamava afana nento into yokuba izinja zibukeka zingacacanga. Kodwa abantu banokugxila lula kwizifundo ezikufutshane. Abazalwana bethu abancinci abambalwa, njengoko abanye bacinga. Banoba nobuncinane obukhulu (malunga ne-0.5 diopters). Olunye umehluko phakathi kweenja kunye nabantu kukuba iliso lomntu lisesisikweni esifanayo, kwaye zilapha - ezi zintlukwano ziyahlukana kancane kumacala, malunga nama-20 degrees. Amanqaku acatshulwe axhomekeke kummandla omkhulu wezilwanyana, isakhiwo sekhanga kwizilwanyana ezahlukeneyo siyahluka kakhulu. Thelekisa, umzekelo, intloko ye- pug , i-Pekingese kunye nomalusi waseJamani . Kodwa nangona kunjalo, intsimi yombono wale zi lwanyana iya kuba yinto engaphezulu kunayo. Izinja zethu zinomfanekiso opheleleyo nje kuphela kwizinto abazibonayo ngamehlo abo, kodwa ngeendlela ezininzi kuxhomekeke kwintsingiselo yokuvumba nokuva.
Umbuzo wukuthi, iinja zibona umbala, sele sithethe ngazo. Yisiphi umfanekiso abayibona kwiTV? Iimvumi zethu zethelevishini zenzelwe abantu. Isreyimu sabo sinjalo ukuba ezi zilwanyana azikwazi ukujonga umfanekiso oqhelekileyo kwisikrini (ukuba izinja akufanele zibe ngaphantsi kwe-80 HZ). Esikhundleni se-movie, i-Bobics kunye neBhola zibona enye i-melteshenie. Kodwa iiTV ezitsha kunye nereyithi ye-Hz ye-100 Hz yabazalwana bethu abancinci banomdla. KwaseNtshona, kwaqala ukudubula iidibhoni ezikhethekileyo zezilwanyana ezifuywayo
