Kodi ndi mmene kuwona mtundu akhungu - popanda mtundu dziko

Mtundu khungu ndi khalidwe lomwe ndi munthu chibadwire kapena chifukwa limene mitsempha kapena diso matenda. Ngati matenda obadwa nawo, kuchiza sikutheka. Khungu chifukwa matenda angayambe diso limodzi kapena onse nthawi imodzi. Pankhani ya matenda anapeza pa mankhwalawo kudwala chimapangitsa anthu masomphenya anthu amakhala bwinobwino, ndipo ngati chilema kusiyiratu. Ndi zikomo kwa anthu awa, tingathe kumvetsa bwino mmene kuwona mtundu wakhunguyo, ndi momwe kwambiri pamfundo maganizo awo a dziko. Chifukwa chikhalidwe cha chibadwa zowawa kobadwa nako mtundu khungu, kawirikawiri anthu. Akazi colorblind kukumana nthawi makumi awiri zochepa. Zodabwitsa ndizakuti, ndi Dziwani kuti, mpaka posachedwapa, madokotala anali otsimikiza kuti akazi monga matenda alibe kufalitsa. Komano, mwakanthawi madona kutaya luso kusiyanitsa mitundu. Nkhani ndi zaka kapena monga chotsatira cha kuvulala lalikulu.

Kupeza momwe kuona mtundu wakhunguyo, tiyenera kukumbukira kuti ambiri a iwo saona mtundu umodzi wokha - buluu, wobiriwira kapena wofiira, koma ena saona mitundu iwiri yokha (nthunzi khungu) kapena sakuzindikira pa mitundu yonse (mtundu khungu).

Mavuto cholandilira mtundu tcheru ili mbali yaikulu ya diso kwa diso, ndi chifukwa cha zosalongosoka mtundu masomphenya. Special maselo mitsempha (cones) zolandilira udindo. Pali mitundu itatu ya cones, imakhudza momwe iwo khungu-akhungu. Aliyense wa awa mitundu mitundu tcheru mapuloteni lili pigment amene ali ndi udindo kwa maganizo a mtundu kwambiri. Mu anthu khungu kobadwa nako, ndondomeko olumikizidwa ku makina amenewa mtundu ikuyambitsa pigment (mmodzi, ziwiri, kapena onse atatu nthawi imodzi).

Kudziwa kuyan'anila za mtundu kuzindikira ntchito polychromatic mayeso tebulo, limene manambala kapena akalumikidzidwa yosavuta kukopedwa ndi mabwalo akuda. Pa anomaly, iwo khungu-akhungu, iwo sangathe kuona manambala kapena kanjedza. Munthu ndi masomphenya zachilendo kuwona chithunzi yomweyo.

Mankhwala mankhwala a mtundu khungu kobadwa nako, ndipo palibe njira imodzi kulibe mpaka posachedwapa, kupirira matenda. Mu 2009, gulu la asayansi American anayesa kuthetsa vuto la khungu mtundu ntchito jini zomangamanga. Mwa kuyambitsa chibadwa cha anyaniwa anakwanitsa kuthetsa kuyan'anila za mtundu maganizo ndi kutsimikizira kuti sikutanthauza kusintha wamanjenje dongosolo kuti alandire mtundu watsopano.

Palinso ena njira ya kusintha mtundu mothandizidwa ndi magalasi zapadera. Osati choncho kalekale, linaikidwa kwa magalasi mtundu-akhungu ndi magalasi Lilac mtundu kwa mtundu khungu uphungu. Ndiyamika mfundo mungathe kusiyanitsa pakati wobiriwira ndi wofiira mitundu, amene bwino masomphenya mtundu wa anthu ndi mawonekedwe wamba khungu mtundu. Komanso akhoza kwambiri kusintha mtundu maganizo zosasonyeza mtundu wake weniweni ndi wofiira magalasi kulocha kukhudzana, amene ntchito zina ndi mayesero, koma iwo sangakhoze ntchito avale mosalekeza.
