Kodi munapitapo kwa dokotala kuti akakuoneni maso? Mwina mukukumbukira pamene munapita, ankakupangitsani kukhala pampando, kuyika tchati chachikulu pakhoma patali pang'ono, ndikukupemphani kuti muwerenge zilembo zomwe zili pamenepo chimodzi ndi chimodzi. Muyenera kuwerenga kuyambira chilembo chapamwamba mpaka chilembo chaching'ono, mzere ndi mzere. Nthawi zina muyenera kutseka diso limodzi, kenako linalo... Imeneyo ndi mayeso osavuta omwe tonse timawadziwa, omwe amatchedwa Visual Acuity Test . Mwachidule, amawunika momwe maso anu alili akuthwa . Lero, tikambirana izi mwatsatanetsatane , ngati kuti mukulankhula ndi mnzanu.
Kodi mayeso a Visual Acuity Test ndi chiyani kwenikweni?
Kuwona bwino kumangotanthauza "kuona bwino" kapena "kuona bwino". Kumatanthauza momwe mungasiyanitsire bwino mawonekedwe ndi tsatanetsatane kuchokera patali. Mukayenda mumsewu, kodi mungawerenge bwino zilembo zomwe zili pa chikwangwani chomwe chili patali? Kodi mutha kuwona nambala yomwe ili m'basi kuchokera patali? Zinthu ngati zimenezo zimatsimikiziridwa ndi kuwona bwino kwanu.
Kotero mayeso awa ndi njira yachangu komanso yosavuta kwambiri kuti dokotala aone ngati maso anu asintha pakapita nthawi. Ndi gawo loyamba komanso lofunika kwambiri pakuwunika maso.
N’chifukwa chiyani mayesowa ndi ofunikira kwambiri?
Mayeso osavuta awa amatha kuzindikira mavuto ambiri omwe amakumana nawo m'maso mwathu msanga. Makamaka, amagwiritsidwa ntchito kuzindikira mavuto anayi akuluakulu omwe amadziwika kuti zolakwika za refractive.
- Kuona Pafupi / Myopia: Apa ndi pamene mungathe kuona zinthu zomwe zili pafupi nanu momveka bwino, koma zinthu zomwe zili kutali sizikuwoneka bwino. Mwachitsanzo, kuwerenga buku kuli bwino, koma kuonera TV kapena kuona nambala m'basi pamsewu sikukuwoneka bwino.
- Kuona Patsogolo / Kuona Kwambiri: Izi ndi zosiyana ndi zomwe zinalipo kale. Ngakhale kuti zinthu zakutali zimatha kuwoneka bwino, zinthu zapafupi, makamaka powerenga buku kapena nyuzipepala kapena poyang'ana foni, zimaoneka ngati zachimbuuzi. Maso amamva kutopa.
- Matenda a Astigmatism: Ichi ndi vuto losiyana pang'ono. Chifukwa diso siliyang'ana bwino kuwala, mutha kuwona zinthu zomwe zili pafupi komanso kutali monga zopotoka pang'ono, zotambasuka, kapena zosawoneka bwino. Chizindikiro chimodzi cha izi ndikuwoneka kwa mizere yozungulira magetsi a galimoto usiku.
- Presbyopia: Iyi si matenda. Ndi vuto lachilengedwe lomwe limachitika pamene lenzi ya maso athu itaya kusinthasintha kwake titakwanitsa zaka 40. Izi zimapangitsanso kuti zikhale zovuta kuwona zinthu zomwe zili pafupi, monga kuyang'ana nyuzipepala kapena kumanga chingwe.
Kuwonjezera pa mavuto akuluakulu anayiwa, mayesowa nthawi zina angagwiritsidwe ntchito ngati sitepe yoyamba yofufuza matenda monga khungu losawona bwino.
Pali mitundu ingapo ya mayeso a kuwona bwino.
Tonsefe tikudziwa tchati chokhala ndi zilembo, koma pali njira zingapo zochitira mayesowa. Amasiyana malinga ndi msinkhu ndi zosowa za munthuyo.
| Dzina la mayeso | Mwachidule... |
|---|---|
| Tchati cha Kuyesa Maso a Snellen | Iyi ndi njira yakale yomwe tonse timaidziwa. Tchati chomwe chili pakhoma chimachepa kuyambira pamwamba mpaka pansi. Masomphenya amayesedwa ndi mzere wocheperako womwe mungawerenge. Tsopano m'malo ena, izi zimawonetsedwa pakhoma. |
| Tchati cha E Chosasinthika | Izi zikufanananso ndi tchati cha Snellen. Koma ichi chili ndi chilembo 'E' chokha. Mu mzere uliwonse, chilembo E chimatembenuzidwa mbali zosiyanasiyana, monga mmwamba, pansi, kumanja, ndi kumanzere. Izi zitha kuchitika ngakhale ndi ana aang'ono omwe sangathe kuwerenga zilembo, kapena ndi munthu amene sadziwa chilankhulocho. Ingolozerani mbali ya chilembo 'E' yomwe ili ndi miyendo itatu. |
| Mayeso a Pinhole Visual Acuity | Izi zimachitika kuti mudziwe bwino vuto monga kusawona bwino. Apa, mumapatsidwa chipangizo (chopondera) chokhala ndi dzenje laling'ono kapena mabowo angapo. Mukupemphedwa kuti muyang'ane kudzera m'dzenjelo ndikuwerenga tchati. Izi zimathandiza kulamulira kuwala komwe kumalowa m'diso ndikupeza vuto lenileni la masomphenya. |
| Mayeso a ana (Mayeso a Cardiff) | Tangoganizirani, kodi mumayang'ana bwanji maso a mwana wamng'ono amene satha kuwerenga?Nthawi zina ngati zimenezi, m'malo mwa zilembo, amagwiritsa ntchito tchati chokhala ndi zithunzi zosiyanasiyana za nyama, magalimoto, ndi nyumba. Dokotala amawonetsa zithunzizo ndikufunsa mwanayo kuti ndi chiyani. Izi zimapatsa chithunzi cha momwe mwanayo amaonera zinthu. |
Umu ndi momwe mayeso amagwirira ntchito:
Iyi ndi njira yosavuta kwambiri. Izi ndi njira zomwe nthawi zambiri zimatsatiridwa:
1. Kutali: Mudzakhala pansi kapena kuimitsidwa pampando pafupifupi mamita 20 kuchokera pomwe pali tchati.
2. Kutseka diso limodzi: Kenako, dokotala adzakuuzani kuti mutseke diso limodzi ndi dzanja lanu kapena kachipangizo kakang'ono komwe kali ndi dzanjalo. Simungathe kungoyang'ana m'zala zanu, sichoncho?
3. Kuwerenga zilembo: Tsopano mukupemphedwa kuti muwerenge zilembo motsatizana kuyambira chilembo chachikulu kwambiri pamwamba pa tchati, pansi.
4. Kuzindikira Malire: Mumapitiriza kuwerenga mpaka mutafika poti simungathe kuwerenga zilembo momveka bwino, ndipo zimakhala zosamveka bwino.
5. Kuyesa diso lina: Diso limodzi likatha, litseguleni, tsekani diso lina, ndikubwereza mayesowo kuyambira pachiyambi.
Chofunika kwambiri ndi kusayang'ana mozama ndikuyesera kuwerenga zilembozo pamene zili zazing'ono kapena zosamveka bwino. Kuchita zimenezi kudzakulepheretsani kupeza chithunzi cholondola cha masomphenya anu. Sizikutanthauza kuti muyenera 'kupambana' ngati mayeso. Chofunika kwambiri ndi kuuza dokotala wanu moona mtima momwe mukuonera.
Ngati mwavala kale magalasi kapena ma contact lens, dokotala wanu angachite mayesowa kawiri.
- Popanda magalasi: Yesani maso anu achilengedwe (maso osakonzedwa).
- Kuvala magalasi: Onani momwe magalasi anu amakono akukonzerani maso anu.
Kodi zotsatira zake zikuti chiyani? Kuyang'ana kumbuyo ndi 20/20...
Mayeso akatha, masomphenya anu amafotokozedwa m'magawo. Mwina mwamvapo nkhani ya "masomphenya a 20/20." Amanena kuti m'mafilimu, "Masomphenya ake ndi angwiro, 20/20."
Tanthauzo la izi ndi losavuta kwambiri.
Kuwona kwa 20/20 kumatanthauza kuti chinthu chomwe munthu amene ali ndi maso abwinobwino angathe kuchiwona bwino ali pa mtunda wa mamita 20 chidzawoneka bwino ngati chili pa mtunda wa mamita 20.
Tangoganizani kuti maso anu ali 20/40. Izi zikutanthauza kuti kuti muwone bwino chinthu chomwe munthu wabwinobwino angachione pa mtunda wa mamita 40, muyenera kukhala pafupi mamita 20. Izi zikutanthauza kuti maso anu ali pansi pa avareji.
Komanso, ngati maso anu ali 20/15, zikutanthauza kuti maso anu ndi akuthwa kuposa apakati. Mungathe kuona bwino kuchokera pa mtunda wa mamita 20 zomwe munthu wabwinobwino angaone kuchokera pa mtunda wa mamita 3.
Koma kumbukirani kuti anthu ambiri saona bwino popanda kukonzedwa. Zimenezo n’zachibadwa. Pambuyo poyesedwa, dokotala wanu adzakuuzani zomwe muyenera kuchita kuti mukonze maso anu. Nthawi zambiri, mudzapatsidwa magalasi kapena magalasi olumikizirana.
Kuyesa Kuwona ndi gawo limodzi lokha la mayeso anu athunthu a maso. Pambuyo pake, dokotala adzayang'ana kuthamanga kwa maso anu, mitsempha yomwe ili mkati mwa diso lanu, ndi zinthu zina zambiri pogwiritsa ntchito zida zina (monga nyali yodulidwa).
Uthenga Wopita Nawo Kunyumba
- Mayeso a Kuona ndi osavuta, osapweteka, koma ofunikira kwambiri omwe amayesa kuthwa kwa maso anu.
- Izi zimathandiza kwambiri pozindikira msanga matenda ofala a maso monga kuwona pafupi ndi kuwona patali.
- Pa nthawi ya mayeso, lankhulani zoona ndi dokotala za momwe mukuonera . Musamatseke maso ndi kuyesa kuwerenga movutikira. Iyi si mayeso omwe muyenera 'kupambana'.
- Ngati muli ndi zizindikiro monga mutu, kutopa kwa maso, kapena kusawona bwino, onetsetsani kuti mwaonana ndi dokotala ndikuyesedwa maso anu.
- Kuti maso athu akhale athanzi, ndikofunikira kwambiri kuyesedwa maso nthawi zonse . Monga makolo, nthawi zonse tiyenera kudera nkhawa ndi maso a ana athu.
