Indlela ezibona ngayo
isicabucabu esigxumayo ibona kanjani umhlaba?
Amehlo amancane — abukhali kunawo wonke ngosayizi wawo
Isicabucabu esincane esigxumayo sishaya ngokumangalisayo ngaphezu kwesisindo saso ekuboneni. Kumehlo aso ayisishiyagalombili, amabili amakhulu abheke phambili anikeza umbono ocije kunawo wonke owaziwayo esilwaneni sosayizi waso, ozwela i-ultraviolet nokuluhlaza, kuyilapho amehlo amancane asecele eshanela ukunyakaza. Kuwumzingeli obonayo ochwensa futhi agxume njengekati kunokubamba inyamazane kubulembu.
Umuntu ≈ 60 cpd (20/20)
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.
Ukubona umbala
Umbala we-UV-oluhlaza, weluliwe kuya kobomvu kwezinye izinhlobo ngesihlungi ku-retina. Ecacile ngokumangazayo kumehlo amancane kangaka.
Ama-photoreceptor
Amehlo aphambili: amaseli e-cone e-UV + oluhlaza (amanye anesihlungi sobomvu); amapheya ama-4 amehlo
Iziqongo zokuzwela kwama-cone
- UV360 nm
- Oluhlaza530 nm
Ukubona ekukhanyeni okuncane
Abazingeli abasebenza emini.
Uma kuqhathaniswa nokubona komuntu
Ngokweqiniso imininingwane yesicabucabu esigxumayo, cishe ku-20/125, ihlala ngaphansi kakhulu kwe-20/20 yakho, yize imangalisa iso elincane kangaka. Sibona i-ultraviolet ongeke uyibone, kumehlo ayisishiyagalombili amboza indawo yaso eningi kakhulu kunamabili akho.
Izici eziphawulekayo
- Ubukhali obukhulu kunazo zonke ngokobukhulu bawo kunoma yisiphi isilwane
- Amehlo aphambili we-telephoto anenetina enyakazayo
- Amehlo ayisishiyagalombili ukuze abe nolwazi lwango-360°
Imibuzo evame ukubuzwa
isicabucabu esigxumayo ibona kanjani umhlaba?
Isicabucabu esincane esigxumayo sishaya ngokumangalisayo ngaphezu kwesisindo saso ekuboneni. Kumehlo aso ayisishiyagalombili, amabili amakhulu abheke phambili anikeza umbono ocije kunawo wonke owaziwayo esilwaneni sosayizi waso, ozwela i-ultraviolet nokuluhlaza, kuyilapho amehlo amancane asecele eshanela ukunyakaza. Kuwumzingeli obonayo ochwensa futhi agxume njengekati kunokubamba inyamazane kubulembu. Umbala we-UV-oluhlaza, weluliwe kuya kobomvu kwezinye izinhlobo ngesihlungi ku-retina. Ecacile ngokumangazayo kumehlo amancane kangaka.
Yimiphi imibala isicabucabu esigxumayo engayibona?
Umbala we-UV-oluhlaza, weluliwe kuya kobomvu kwezinye izinhlobo ngesihlungi ku-retina. Ecacile ngokumangazayo kumehlo amancane kangaka. Amehlo aphambili: amaseli e-cone e-UV + oluhlaza (amanye anesihlungi sobomvu); amapheya ama-4 amehlo
Ukubona kuka-isicabucabu esigxumayo kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-6 ngedigri (20/125 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/20). Ibanga layo lokubona lisabalala cishe ngo-320°.
isicabucabu esigxumayo ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-6 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-10 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.
isicabucabu esigxumayo ibona kanjani ebumnyameni?
Abazingeli abasebenza emini.
Yini eyisipesheli ngokubona kuka-isicabucabu esigxumayo?
Ubukhali obukhulu kunazo zonke ngokobukhulu bawo kunoma yisiphi isilwane. Amehlo aphambili we-telephoto anenetina enyakazayo. Amehlo ayisishiyagalombili ukuze abe nolwazi lwango-360°. Ngemuva kweso ngalinye elikhulu eliphambili kukhona ishubhu elide elinama-retina anyakazayo isicabucabu esingakwazi ukuwaphenya ukuze siskene umbukwane, njengokuphenya ikhamera encane ye-telephoto, konke ngaphakathi kwekhanda elibanzi ngamamilimitha ambalwa.
Ukubona kuka-isicabucabu esigxumayo kuqhathaniswa kanjani nokomuntu?
Ngokweqiniso imininingwane yesicabucabu esigxumayo, cishe ku-20/125, ihlala ngaphansi kakhulu kwe-20/20 yakho, yize imangalisa iso elincane kangaka. Sibona i-ultraviolet ongeke uyibone, kumehlo ayisishiyagalombili amboza indawo yaso eningi kakhulu kunamabili akho.

Khomba ikhamera yakho kunoma yini bese ubuka umhlaba uguquka ube ukubona kwalesi silwane ngesikhathi sangempela.
