Kuthana ndi mayesero olimbitsa thupi ndi njira yofulumira komanso yosavuta yowunikira masomphenya anu. Kuyesedwa koyesa kutsutsana ndiyeso yoyesedwa ndi dokotala kapena diso lanu ngati chida choyang'anira. Kuyesedwa kwa masewera olimbirana kumafuna zinthu zing'onozing'ono kapena zopanda padera ndipo zingathe kuchitidwa pafupifupi zochitika zilizonse. Kafukufukuyu amadziwikanso kuti "kuwerengera kwala" chifukwa woyesayo angagwiritse ntchito zala zake pamayesero.
Zing'onozi zimadziwika kapena kuziwerengera, malinga ndi kuchuluka kwa mayeso. Choyamba, maso onse adzayesedwa (binocular) ndiyeno diso lililonse lidzayesedwa padera. Chilema m'masomphenya chidzawoneka ngati wodwalayo sakulephera kuwona molondola zala.
Momwe Ikugwirira Ntchito
Poyamba kuyesa, mudzafunsidwa kuti mutseke diso limodzi, ndikuyang'ana maso anu. Wowunikayo adzayendetsa kayendedwe ka chala, kubweretsa manja ake kumalo anu oonekera kuchokera kumbali. Chifukwa masomphenya anu adagawidwa m'magulu anayi mu ubongo wanu, woyezetsayo adzayimirira zala iliyonse. Mukhoza kunena zala zazing'ono zomwe mumaziona popanda kuziyang'ana, kotero kuyesa malo anu, kapena mbali, masomphenya.
Pogwiritsa ntchito zotsatira za mayeso, dokotala wanu adzatha kudziwa ngati mukuvutika kuona m'madera ena a masomphenya anu, komanso zomwe zingayambitse. Masewero olimbana ndi vutoli amathandizanso kuti azindikire mawanga ndi maso , komanso matenda ena.
Mavuto a m'munda ali ndi zifukwa zambiri zomwe sizichokera nthawi zonse. Dokotala wanu angagwiritse ntchito chidziwitso kuchokera ku mayesero owonetsera masomphenya kuti azindikire mavuto awa:
- glaucoma
- macular
- optic glioma
- chotupa cha ubongo
- multiple sclerosis
- kupwetekedwa
- temporal arteritis
- matenda oyambitsa matenda a mitsempha
- matenda osokoneza bongo
- kuthamanga kwa magazi
Kuyezetsa Masewera a Masewera olimbitsa thupi
Makina opanga makina opanga makompyuta amapereka malipoti olondola komanso olondola kuposa njira zoyesera zala. Pakati pa kuyezetsa, zizindikiro zazing'ono zikuwonekera pazenera ndipo wodwala ayenera kuyang'ana patsogolo ndikusindikiza batani akawona kuwala kwa kuwala. Kuwala kukuwalira kumasiyana mowala. Makinawa adzapeza kuwala kochepa kofunikira kuti wodwala awone kuwala kwake pa malo alionse kapena padera.
Kuyang'ana Munda Wamasewera monga Chida Chodziwiritsira
Kuyezetsa masewera olimbitsa thupi kumagwiritsidwa ntchito kawirikawiri kuti azindikire kapena kuyang'ana glaucoma. (Glaucoma ndi matenda omwe amadziwika ndi kuthamanga kwa diso.) Mitundu yambiri ya glaucoma imayamba ndi kutayika kwa masomphenya. Palibe mankhwala a glaucoma, kuleka kupitirira kwa matendawa kumathandiza kusunga masomphenya. Kupitirira kwa matendawa kumayenera kuyang'anitsitsa mosamala kwambiri poyang'ana malo omwe akuwonetserako komanso kupanikizika kwa m'mimba.
