Indlela ezibona ngayo
ihlengethwa ibona kanjani umhlaba?
Ulwandle olunombala owodwa, oluqondiswa i-sonar
Amehlo ehlengethwa asebenza emhlabeni emibili, ehlala ecijile ngaphansi kwamanzi naphezulu emoyeni, yize ependa lowo mhlaba ngaphandle kombala. Njengoba lisilela ikhoni eliluhlaza okwesibhakabhaka, ihlengethwa libona kuphela ngamazinga okukhanya, alungiselelwe okuluhlaza okwesibhakabhaka-luhlaza kolwandle. Iningi 'lokubona' kwalo, empeleni, kwenziwa ngomsindo, i-echolocation yalo idweba isithombe umbono wodwa ongeke uwunikeze.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-ihlengethwa kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-2.5 ngedigri (20/240), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-300°.
ihlengethwa ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-2.5 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-24 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 ihlengethwa engayibona?
Cishe ayiboni umbala; ibona umhlaba ongaphansi kwamanzi ngezinga lokukhanya, inokuzwela oluhlaza sasibhakabhaka-luhlaza lwamanzi.
Ama-photoreceptor
I-Monochromat yamaseli e-cone (ayinaso iseli e-cone eluhlaza sasibhakabhaka) + amaseli e-rod
Iziqongo zokuzwela kwama-cone
- I-cone eyodwa e-L524 nm
ihlengethwa ibona kanjani ebumnyameni?
I-retina egcwele amaseli e-rod ne-tapetum lucidum yamanzi ajulile nokukhanya okuncane.
Ukubona kuka-ihlengethwa kuqhathaniswa kanjani nokomuntu?
Lokho ihlengethwa elingakwenza wena ongeke ukwenze ukugxila ngokulinganayo emanzini nasemoyeni; cwilela ngaphansi kwendawo umbono wakho uba luvivi. Emininingwaneni evamile libona cishe ku-20/240 kune-20/20 yakho, futhi awunambala kwizigidi zakho.
Yini eyisipesheli ngokubona kuka-ihlengethwa?
- Igxila kahle emanzini nasemoyeni
- I-echolocation ingumuzwa oyinhloko webanga
- Izindawo ezimbili ze-retina ezinobukhali obukhulu
