Indlela ezibona ngayo
ikati ibona kanjani umhlaba?
Umbala ofiphele, ukubona ebusuku okungenakwehlulwa
Amehlo ekati akhelwe ukuzingela ekuseni nasentambama, hhayi ukubukela ukushona kwelanga. Umbala ufika ugezekile futhi ubuthakathaka, futhi noma yini eseduze ngaphansi kwamasentimitha angu-25 iba luvivi, yingakho ikati linuka ukudla okuphethwe ngaphansi kwekhala lalo kunokuligqolozela. Lokho elikulahlekelwayo embaleni nasekugxileni okuseduze likubuyisela ebusuku, lapho amehlo alo emunca ukukhanya okuncane kunakho konke.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-ikati kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-5 ngedigri (20/120), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-200°.
ikati ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-5 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-12 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.
Ukuqhathanisa imibala
How each colour shifts when seen through this animal's eyes, using the same colour model as the app. Tones a screen can't emit (such as ultraviolet) are shown as an approximation.
Yimiphi imibala ikati engayibona?
Umbala obuthaka nongagcwele, obuswa okuluhlaza sasibhakabhaka nokuphuzi; ukuhlukanisa okubi phakathi kobomvu noluhlaza futhi jikelele akunandaba nombala.
Ama-photoreceptor
I-Dichromat (izinhlobo ezi-2 zamaseli e-cone), ibuswa kakhulu amaseli e-rod
Iziqongo zokuzwela kwama-cone
- S (oluhlaza sasibhakabhaka)450 nm
- L (oluhlaza-phuzi)550 nm
ikati ibona kanjani ebumnyameni?
I-cornea enkulu, isikhala esiyisikwele nokungqama, ne-tapetum lucidum enamandla: ibona cishe ngengxenye eyodwa kweziyisithupha yokukhanya esikudingayo thina bantu.
Ukubona kuka-ikati kuqhathaniswa kanjani nokomuntu?
Emini ikati libona cishe ku-20/120 uma kuqhathaniswa ne-20/20 yakho, futhi imibala yalo ibukeka ifiphele eceleni kweyakho. Uma sekuhlwa isimo siyaguquka: likubona kangcono kunawe ebumnyameni obucishe bube phelele, kubanga elingu-200-degree elicishe lilingane neyakho.
Yini eyisipesheli ngokubona kuka-ikati?
- Ukubona okuhle kakhulu ekukhanyeni okuncane
- Ukubona okuhle kakhulu ukunyakaza
- Iyafiphala eduze (<25 cm)
