Tanthauzo: "Kuwona kachiwiri" kumatanthawuza kusintha kwa kanthawi m'masomphenya pa chitukuko choyambirira cha cataract . Masomphenya asanawonongeke, masomphenya, makamaka masomphenya owona bwino, amakula kwambiri. Odwala ena amafotokoza momveka bwino pafupi ndi masomphenya popanda kugwiritsa ntchito magalasi owerengera . Pafupi masomphenya amatanthawuza masomphenya a zinthu ziwiri kapena pafupi ndi wowona. Kusintha uku kumachitika chifukwa mapuloteni ndi mankhwala ena omwe amapangira lenti amayamba kusintha maonekedwe.
Izi zimasintha momwe kuwala kumayendera kudzera mu lens, zomwe zimachititsa kusintha kwa kanthaŵi kochepa m'masomphenya pafupi.
Kodi aliyense angakumane ndi "Kuwona Kachiwiri?"
Ayi. Ngakhale kuti tonsefe timakumana ndi kusintha komwe kumachitika mkati mwa lens, zotsatira zake zimadalira mtundu wa masomphenya omwe wodwalayo anali nawo kale, zomwe zinali zowonongeka ndi maso awo. Mwachitsanzo, ngati mutayang'ana kale, "Kuwona Kachiwiri" kudzakuchititsani kuti muyang'ane kwambiri. Anthu omwe amapeza ubwino wa "Kuwona Kachiwiri" amakhala akuyang'anitsitsa kapena samakhala ndi vuto la masomphenya poyambira.
N'chifukwa chiyani crystalline lens amasintha?
Maso athu amavutika nthawi zonse ndi zinthu zina. Njira imodzi imene matupi athu nthawi zonse amamenyana ndi kuwonongeka kwa mavitamini, komwe kumatchedwanso kusautsidwa kwa okosijeni. Kupanikizika kwa oxidative ndikumenyana kosalekeza kuti matupi athu amenyane ndi zowonongeka zaulere, zomwe zimakhala ndi ma molekyulu okhala ndi oxygen omwe amawopsa kwambiri ndipo amawononga maselo m'thupi lathu.
Kupsyinjika kwa oxidative kungasinthe maselo omwe ali mkati mwa diso la diso limene limachititsa kuti disolo liwonongeke pang'onopang'ono. Ngakhale kuti izi zimachitika pang'onopang'ono m'miyoyo yathu yonse, zimatikhudza tikamakalamba ndipo zisanayambe kukhudza masomphenya athu, nthawi zambiri timakhala ndi "kuyang'ana".
Kodi cataract ndi chiyani?
Katemera wathanzi ndi khungu la diso la diso . Anthu ambiri okalamba amakhala ndi vuto la kupweteka kwambiri chifukwa chodwala matendawa. Nthenda ya cataract imakhala yopweteka kwambiri. Kawirikawiri imayamba ngati malo ochepa, opaque ndipo amakula pang'onopang'ono. Masomphenya sagwiritsidwa ntchito mpaka malo akuluakulu a lens akukhala mdima. Zizindikiro zowopsa za cataract zimakhala zosaoneka bwino, zowonetsera kuwala, zowonetsera kuwala, zovuta kuyendetsa usiku, zowoneka masomphenya, zoyenera kuwerenga, masomphenya awiri kapena kusintha kwakukulu zolemba zamaso.
Kodi mungatani ngati mukuganiza kuti mukuwonanso kachiwiri?
Ngati mukuganiza kuti mukuwerenga bwino posachedwa popanda magalasi anu, onani optometrist kapena ophthalmologist.

Dokotala wanu wa diso adzayesa chiwonetsero chanu chowonetseratu ndi kumaliza kukana, zomwe mukukumbukira kuti mukufunsidwa, "Ndi yani yabwino, imodzi kapena ziwiri?" Kutsutsa kudzasonyeza ngati mankhwala anu adasintha kwambiri.
Dokotala wanu wa diso amathanso kuyang'ana maso anu ndikuyang'anitsitsa pansi pa biocope yapadera kuti muwone ngati chitukuko cha cataract chikuchitika kapena muli ndi kusintha kwachibadwa kwa mankhwala.
