Amphaka amawona dziko mosiyana kwambiri ndi anthu. Werengani apa zomwe amphaka amawona mitundu, chifukwa chake amphaka amagwirizana kwambiri m'nyengo yamadzulo komanso zomwe diso la mphaka liri nalo.
Chidwi cha maso a mphaka chagona kwambiri pa “chifanizo cha mphaka” kusiyana ndi chiwalo chenicheni cha kumva cha mphaka, chomwe kwenikweni n’chofanana ndi mmene maso a munthu amachitira.
Kunena zowona, diso la choyamwitsa chilichonse lili ndi dzenje (mwana) lomwe kuwala kumagwera pa disolo. Kuwala kowala kumasinthidwa ndi mandala ndipo, ikadutsa m'chipinda chamdima (thupi la vitreous), imagwera pamtunda wosamva kuwala (retina). Apa zimabwera ku chithunzi cha zomwe zikuwoneka.
Amphaka Amatha Kuwona Mitundu Iyi
Dziko la mphaka mwina ndi lotuwa pang'ono kuposa lathu. Zolandira m’diso la mphaka zimapangidwa ndi ma cones ochepa, omwe ndi maselo amene amatilola kuona mtundu. Amphaka amakhalanso opanda ma cones omwe amamva kuwala kofiira. Mwachitsanzo, mphaka amatha kusiyanitsa zobiriwira ndi buluu, koma amawona zofiira ngati mithunzi ya imvi.
M'malo mwake, mphaka ali ndi "ndodo" zambiri zomwe zimakhala ndi mphamvu zowunikira komanso kuzindikira kwamdima. Kuphatikiza apo, mphaka ndi mbuye wa "diso lofulumira". Ma cell apadera m’maso mwake amakhala ngati zodziŵira kuti akuyenda ndipo amamuthandiza kuchitapo kanthu pa liwiro la mphezi. Kuphatikiza apo, amphaka amawona mayendedwe mwatsatanetsatane. Amatha kukonza mafelemu ambiri pamphindikati kuposa anthu.
Kafukufuku wa Zoological Institute ku Mainz anasonyeza kuti amphaka ambiri ankakonda mtundu wa buluu. Kuti apite ku chakudya, amphaka ankayenera kusankha pakati pa chikasu ndi buluu. 95% adasankha buluu!
Maso a Amphaka Ndi Aakulu Powayerekeza ndi Diso la Munthu
Ndi mainchesi 21 mm, diso la mphaka ndi lalikulu - poyerekeza, maso a munthu wamkulu amafika mainchesi 24 mm.
Kuphatikiza apo, diso la mphaka limawoneka lolimba. Anthufe tinazolowera kuona zoyera zambiri pamaso pa anthu anzathu. Anthu akasintha kolowera komwe amayang'ana, iris imawoneka ngati ikuyenda pagawo loyera la diso. M’mphaka, zoyera zimabisika m’diso. Ngati mphaka asintha komwe amayang'ana, sitiwona "oyera" ndipo timakhulupirira kuti maso ali chete.
Ana, omwe amatha kung'ambika m'mizere yoyima, amadetsa nkhawa anthu ena chifukwa amakumbukira maso a nyamakazi. M'malo mwake, mphaka wokhala ndi ana oyimirirawa amatha kuwunika momwe kuwala kumawonekera bwino kwambiri kuposa ife anthu omwe timakhala ndi ophunzira athu ozungulira motero amatha kugwiritsa ntchito kwambiri kuwalako.
Ndichifukwa chake Amphaka Amawona Bwino Kwambiri Madzulo
Maso amphaka amadziwika ndi luso lawo lowunikira. Amphaka amatha ndi kuwala kocheperako kasanu kapena kasanu kuposa anthu, zomwe zimathandiza kwambiri posaka madzulo. Chimodzi mwa zifukwa zomwe zimachititsa kuti amphaka azikhala ndi "clairvoyance" ndi "tapetum lucidum", yomwe imawonekera pa retina ya mphaka. Diso la mphaka limeneli limagwira ntchito ngati “chokulitsa chokulirapo cha kuwala kotsalira” mwa kuonetsa kuwala kulikonse ndipo zimenezi zimachititsa kuti maselo a maso a mphakawo ayambenso kugwira ntchito.
Lens yake yayikulu imathandiziranso kugwiritsa ntchito bwino kuwala. Kupatula apo, amphaka ali ndi maselo omwe samva kuwala kuwirikiza kawiri kuposa a anthu. Ichi ndichifukwa chake amphaka amatha kuwona bwino kwambiri madzulo. Komabe, payenera kukhala kuwala pang'ono, mumdima wandiweyani mphaka sangathenso kuwona chilichonse.
Ngakhale kuti maso a mphaka amawalira, saona akuthwa kwambiri. Kumbali imodzi, iwo satha kuwongolera maso awo kuti ayang'ane patali, komano, ali ndi ngodya yayikulu yowonera poyerekeza ndi anthu. Mbali ya mawonekedwe a maso ndi muyeso wa kuthekera kolekanitsa mfundo ziwiri zomwe zili pafupi.
