Khungu lofala kwambiri la mtundu ndilololandira. Komabe, ubongo umatha kuyambanso chifukwa cha matenda monga macular , poizoni ndi zotsatira za mankhwala. Azimayi nthawi zambiri amakhala 'otengera' a chilema chomwe chimadutsa pa chromosome yopanda vuto. Ambiri ndi abambo omwe amalandira ubongo wa mtundu, omwe amachititsa amayi amodzi (1) mwa amayi makumi awiri (1) mwa amayi khumi (200) alionse.
Mu khungu la mtundu, pali chiwerengero chochepa cha maselo a cone mu retina wa diso. Ndi retina yomwe imayambitsa masomphenya a mitundu. Pali mitundu itatu ya selo ya khungu, yofiira, ya buluu ndi yobiriwira, yomwe imagwirizana ndi kuwala. Mtundu wa ubweya wa munthu umene umakumana nawo umadalira kuwonongeka kwake ndi magulu a maselo omwe amakhudzidwa.
Masomphenya mwiniwake sakhudzidwa, koma amatha kusiyanitsa pakati pa mitundu ina.
Mafomu a Khungu Wakhungu
Wachizoloŵezi
Khungu lofala kwambiri la mtundu ndi ubweya wofiira. Amadutsa mumasewero olakwika a mtundu wa jeni pa X chromosome ngati matenda opatsirana. Mtundu uwu umakhudza mwamuna mmodzi mwa khumi ndipo uli ndi mitundu iwiri. Mu mawonekedwe amodzi zosiyana zofiira zimawoneka zosakaniza ndi zosazindikiranso ndi masamba ena, malalanje, mapepala otumbululuka, ndi zofiira zonse zimawonekera ngati hue yomweyo, zosiyana ndi mphamvu zawo zokha.
Kawirikawiri
Mu ubongo umodzi wosadziwika, ubongo ndi chikasu sungadziwike.
Khungu lina losadziwika la mtundu limatanthauza kuti mitundu yonse imawonekera mu zakuda ndi zoyera.
Njira Zothandizira
Palibe mankhwala a masomphenya olakwika omwe amawalandira. Kupunduka kwa ubongo chifukwa cha matenda kapena mankhwala omwe amayamba kudwala amatha kuchiritsidwa nthawi zina.
Magalasi a EnChroma
Magalasi a EnChroma ndi mawonekedwe atsopano opangira mawonekedwe omwe amathandiza anthu (okhala ndi mtundu wobiriwira) kuti azikonda mtundu.
Ngakhale EnChroma siimapanga mtundu wosiyanitsa mitundu kuti munthu athe kupyolera muyeso wa khungu, imathandizira anthu omwe ali ndi mtundu wabwino kuti azindikire zomwe zimakhala ndi masomphenya. Mwachitsanzo, EnChroma lens ingathandize anthu okhala ndi ubongo kuti azikonda kwambiri zinthu monga lamoto lalanje kapena lavender flower petal.
EnChroma ndi lenti yamapulositiki yomwe ili ndi mapaundi pafupifupi 100 a dielectric. Lens ili limagwira ntchito pogwiritsa ntchito kuwala kowala komwe kumapezeka pakati pa anthu okhala ndi zofiira. Makamaka, pogwiritsira ntchito mafelemu ambirimbiri, EnChroma lenses imayendetsa mbali ya optic interference kotero kumapangitsa kuganiza kwa reds ndi masamba.
EnChroma sizingatheke komanso zimakhala zovuta. Choyamba, zimatenga pafupifupi 30 mphindi kuti EnChroma lenses ichitike. Chachiwiri, magalasi a EnChroma ndi okwera mtengo kusiyana ndi magalasi omwe nthawi zonse amatha ndipo akhoza kutenga ndalama zochepa madola awiri. Chachitatu, EnChroma lens sizitha kusintha tsiku ndi tsiku m'njira iliyonse yovomerezeka.
Chochititsa chidwi, magalasi a EnChroma angakhalenso obvala ndi anthu opanda mtundu. Kwa anthu omwe ali ndi masomphenya oyenera, EnChroma lens amachititsa mitundu kukhala yamphamvu kapena "pop."
