Kuyesa kwamitundu

Kuyesa kwamasomphenya amitundu kumawunika kuthekera kwanu kusiyanitsa mitundu yosiyanasiyana.

Mukhala pamalo abwino poyatsa nthawi zonse. Wopereka chithandizo chamankhwala adzakufotokozerani za mayeso.

Mudzawonetsedwa makhadi angapo okhala ndi madontho achikuda. Makhadi awa amatchedwa mbale za Ishihara. M'machitidwe, madontho ena adzawoneka ngati manambala kapena zizindikilo. Mudzafunsidwa kuzindikira zizindikirozo, ngati zingatheke.

Mukakutira diso limodzi, woyesayo adzagwira makadiwo mainchesi 14 (35 sentimita) kuchokera pankhope panu ndikukufunsani kuti mupeze mwachangu chizindikirocho chomwe chili mumtundu uliwonse.

Kutengera vuto lomwe mukukayikira, mungafunsidwe kuti mudziwe mtundu wamtundu, makamaka m'diso limodzi poyerekeza ndi linalo. Izi nthawi zambiri zimayesedwa pogwiritsa ntchito kapu ya botolo lofiira la eyedrop.

Ngati mwana wanu akuyesedwa, kungakhale kothandiza kufotokoza momwe mayeso adzamverere, ndikuchita kapena kuchita nawo chidole. Mwana wanu samakhala ndi nkhawa ndi mayeserowo mukawafotokozera zomwe zichitike komanso chifukwa chake.

Nthawi zambiri pamakhala khadi lachitsanzo la madontho amitundu yosiyanasiyana omwe pafupifupi aliyense amatha kuzindikira, ngakhale anthu omwe ali ndi vuto la kuwona kwamitundu.

Ngati inu kapena mwana wanu mumavala magalasi, valani nawo poyesa.

Ana aang'ono atha kufunsidwa kuti anene kusiyana pakati pa kapu ya botolo lofiira ndi zisoti za mtundu wina.

Kuyesaku ndikofanana ndi kuyesa masomphenya.

Kuyesaku kumachitika kuti muwone ngati muli ndi vuto ndi mawonekedwe anu amtundu.

Mavuto owonera mitundu nthawi zambiri amakhala m'magulu awiri:

• Amakhalapo kuyambira pakubadwa (kobadwa nako) m'maselo osazindikira kuwala kwa diso (chingwe chosalira kumbuyo kwa diso) - makadi amtunduwu amagwiritsidwa ntchito pano.
• Matenda a mitsempha yamawonedwe (mitsempha yomwe imanyamula zowonera kuchokera kumaso kupita kuubongo) - zisoti za mabotolo zimagwiritsidwa ntchito pankhaniyi.

Nthawi zambiri, mudzatha kusiyanitsa mitundu yonse.

Chiyesochi chitha kudziwa mavuto amtundu wakubadwa (omwe adalipo kuyambira kubadwa):

• Achromatopsia - khungu lathunthu, atangowona imvi zokha
• Deuteranopia - ndizovuta kudziwa kusiyana pakati pa zofiira / zofiirira ndi zobiriwira / zofiirira
• Protanopia - zovuta kusiyanitsa pakati pa buluu / zobiriwira ndi zofiira / zobiriwira
• Tritanopia - zovuta kusiyanitsa pakati wachikasu / wobiriwira ndi buluu / wobiriwira

Mavuto m'mitsempha yamawonedwe amatha kuwonekera ngati kutayika kwamitundu, ngakhale mayeso amtundu wamakhadi atha kukhala abwinobwino.

Palibe zowopsa pamayesowa.
