Tichifunga nezvemanzwiro anoita katsi, katsi dzomumba dzinogona kuona pamwero upi wechiedza zvichienzaniswa nokuona kwevanhu?
Context:Katsi dzine chiono cheusiku chakaisvonaka uye dzinogona kuona pachikamu chimwe chezvitanhatu bedzi chechiedza chinodikanwa nokuda kwokuona kwomunhu.: 43 Ikoku ndekwechikamu mugumisiro wekuti maziso ekatsi ane tapetum lucidum, iyo inoratidza chiedza chipi nechipi chinopinda kuburikidza neretina kudzokera muziso, nokudaro ichiwedzera kunzwa kweziso kuchiedza chisina kujeka. Meso makuru ndiwo anoenderana nechiedza chisina kujeka. Katsi yomumba ine maziso akaparadzana, ayo anoiita kuti igone kuona chiedza chakajeka pasina kukanganiswa kwemavara. Kana musina chiedza chakanaka, maziso emakati anowedzera kukura zvokuti anofukidza maziso awo akawanda. Katsi yomumba haina kunaka kuona mavara uye ine mhando mbiri chete dzemasero emakona, akagadzirirwa kunzwa ruvara rwebhuruu nerwegirini; kukwanisa kwayo kusiyanisa ruvara rutsvuku nerwegirini hakukwanisi. Mhinduro kumarefu amafungu apakati anobva mugadziriro isiri masero etsvimbo ingava nemhaka yorudzi rwechitatu rwekoni. Ikoku kunoratidzika kuva kugadziridzwa kumwero dzerima rakaderera panzvimbo pokumirira chiono chechokwadi chetricromatic. Katsi dzinewo nhengo dzinoita kuti dzikwanise kupfupfupika dzisingavhiringidzi maziso adzo.
Katsi dzomumba dzinokwanisa kuona nechiedza chinenge chikamu chimwe muzvitanhatu chechiedza chinodiwa kuti munhu aone.
