Mayeso oyang'ana kunyumba

Kuyesedwa kwamasomphenya kunyumba kumayeza kuthekera kowona tsatanetsatane wabwino.

Pali mayesero atatu owonera omwe angachitike kunyumba: gridi ya Amsler, masomphenya akutali, komanso kuyesa masomphenya pafupi.

AMSLER GRID KUYESA

Kuyesaku kumathandizira kuzindikira kuchepa kwa macular. Ichi ndi matenda omwe amayambitsa kusawona bwino, kupotoza, kapena malo opanda kanthu. Ngati mumakonda kuvala magalasi powerenga, valani mayeso awa. Ngati muvala ma bifocals, yang'anani gawo lowerenga pansipa.

Yesani ndi diso lililonse padera, choyamba kumanja kenako kumanzere. Gwirani gridi loyesa patsogolo panu, mainchesi 14 (masentimita 35) kutali ndi diso lanu. Yang'anani pa kadontho pakati pa gridi, osati pagululi.

Mukayang'ana pa kadontho, mudzawona gridi yonseyo m'masomphenya anu ozungulira. Mizere yonse, yowongoka komanso yopingasa, iyenera kuwoneka yowongoka komanso yosasweka. Amayenera kukumana pamadongosolo onse opanda malo akusowa. Ngati mizere iliyonse ikuwoneka yopotoka kapena yosweka, onetsetsani malo awo pa gridiyo pogwiritsa ntchito cholembera kapena pensulo.

Masomphenya akutali

Ili ndiye tchati choyang'ana chomwe madokotala amagwiritsa ntchito, chomwe chimasinthidwa kuti chizigwiritsidwa ntchito kunyumba.

Tchati chimamangirizidwa kukhoma pamlingo woyang'ana. Imani mamita 10 kutali ndi tchati. Ngati mumavala magalasi kapena magalasi olumikizirana ndi masanjidwe akutali, valani mayeso.

Yang'anani diso lililonse padera, choyamba kumanja kenako kumanzere. Khalani otseguka ndi kuphimba diso limodzi ndi chikhatho cha dzanja.

Werengani tchatichi, kuyambira ndi mzere wapamwamba ndikusuntha mizere mpaka kuvuta kuwerenga zilembozo. Lembani nambala ya mizere yaying'ono kwambiri yomwe mukudziwa kuti mwawerenga molondola. Bwerezani ndi diso linalo.

Pafupi MASOMPHENYA

Izi ndizofanana ndi mayeso owonera patali pamwambapa, koma amangokhala mainchesi 14 (masentimita 35) kutali. Ngati mumavala magalasi owerengera, muvale ngati mayeso.

Gwirani khadi loyeserera pafupi ndi masentimita 35 kuchokera m'maso mwanu. Musabweretse khadi pafupi. Werengani tchati pogwiritsa ntchito diso lililonse padera monga tafotokozera pamwambapa. Lembani kukula kwa mzere wochepa kwambiri womwe mudatha kuwerenga molondola.

Mufunika malo owala bwino osachepera 10 mita (3 mita) kutalika kuti muyesedwe masomphenya mtunda, ndi izi:

• Kuyeza tepi kapena choyimira
• Ma chart amaso
• Tepi kapena zolumikizira kuti mupachike matchati amaso pakhoma
• Pensulo yolembera zotsatira
• Wina kuti athandize (ngati zingatheke), popeza atha kuyima pafupi ndi tchatichi ndikukuwuzani ngati muwerenga zilembozo molondola

Tchati cha masomphenya chikuyenera kukhomedwa kukhoma pamlingo wamaso. Chongani pansi ndi chidutswa cha tepi mamita 10 kuchokera pa tchati chomwe chili pakhoma.

Mayesowa samabweretsa mavuto.

Masomphenya anu amatha kusintha pang'onopang'ono osadziwa.

Kuyesedwa kwamaso kunyumba kumatha kuthandizira kuzindikira mavuto amaso ndi masomphenya msanga. Kuyesedwa kwamasamba akunyumba kuyenera kuchitidwa motsogozedwa ndi omwe amakuthandizani kuti mupeze zosintha zomwe zingachitike pakati pa mayeso amaso. Samatenga malo a kuyezetsa kwa akatswiri.

Anthu omwe ali pachiwopsezo chokhala ndi vuto la kuchepa kwa macular atha kuuzidwa ndi dokotala wawo wamankhwala kuti ayese mayeso a gridi ya Amsler pafupipafupi. Ndikwabwino kuyesa izi kangapo kamodzi pamlungu. Kusintha kwanthawi yayitali kumachitika pang'onopang'ono, ndipo mutha kuphonya ngati mungayese tsiku lililonse.

Zotsatira zoyeserera zilizonse ndi izi:

• Kuyesa kwa grid ya Amsler: Mizere yonse imawoneka yowongoka komanso yosasweka popanda malo opotoka kapena osowa.
• Kuyesa kwamasomphenya patali: Makalata onse pamzere wa 20/20 amawerengedwa molondola.
• Pafupi ndi kuyesa masomphenya: Mutha kuwerenga mzere womwe uli ndi 20/20 kapena J-1.

Zotsatira zachilendo zingatanthauze kuti muli ndi vuto la masomphenya kapena matenda amaso ndipo muyenera kuyesedwa akatswiri.

• Kuyesa kwa grid ya Amsler: Ngati gululi likuwoneka lolakwika kapena losweka, pakhoza kukhala vuto ndi diso.
• Kuyesa kwamasomphenya patali: Ngati simukuwerenga mzere wa 20/20 molondola, zitha kukhala chizindikiro cha kuwona patali (myopia), kuwona patali (hyperopia), astigmatism, kapena vuto lina la diso.
• Pafupi ndi kuyesa masomphenya: Kulephera kuwerenga mtundu wawung'ono kungakhale chizindikiro cha masomphenya okalamba (presbyopia).

Mayesowo alibe zoopsa.

Ngati muli ndi izi, funsani akatswiri:

• Zovuta kuyang'anitsitsa zinthu zapafupi
• Masomphenya awiri
• Kupweteka kwa diso
• Kumva ngati pali "khungu" kapena "kanema" pamaso kapena m'maso
• Kuwala kukuwala, mawanga amdima, kapena zithunzi zonga mzimu
• Zinthu kapena nkhope zikuwoneka ngati zosokonekera kapena zopanda pake
• Mphete za utawaleza kuzungulira magetsi
• Mizere yowongoka imayang'ana wavy
• Kuvuta kuwona usiku, kuvuta kusintha zipinda zamdima

Ngati ana ali ndi izi, ayeneranso kuwunika maso awo:

• Maso owoloka
• Zovuta kusukulu
• Kuphethira kwambiri
• Kuyandikira pafupi ndi chinthu (mwachitsanzo, wailesi yakanema) kuti muwone
• Mutu ukulozera
• Kuwombera
• Maso amadzi

Kuyesa kwowoneka bwino - kunyumba; Kuyesa kwa grid ya Amsler

• Kuyesa kwowoneka bwino
