Zooneka bwino

Mwa mphamvu zonse za munthu, masomphenya mwina ndi ofunika kwambiri.

Zowoneka zowoneka bwino

Pofuna kudziwa kuti ophthalmologists amaoneka bwino, nthawi zambiri amagwiritsa ntchito matebulo apadera. Kuti muwone maso a anthu akuluakulu, kawirikawiri amagwiritsa ntchito tebulo la Sivtsev, momwe mizere imakonzedwa makalata, m'munsi, ang'ono (tebulo ndi chilankhulo cha Chilatini amatchedwa tebulo la Snellen). Komabe, tebulo ngatilo silimakulolani kuti muwone molondola zamakono, chifukwa munthu akhoza kulingalira kalatayo ndi mawonekedwe. Mgwirizano wa Golovin, womwe uli ndi mizere ya mphete, ndi discontinuities mosiyana. Pofuna kudziwa kuwona bwino, ana amagwiritsa ntchito matebulo ndi zithunzi za zinthu ndi zinyama.

Matebulo oterowo amakhala ndi mizere 12, ndi makalata kapena zizindikiro za kukula kwake, ndipo amaikidwa mu decimal. Mzere wotsatira uliwonse umagwirizana ndi kuwonjezeka kwa maonekedwe akuwonetsedwa ndi 0.1. Zomwe zimaoneka bwino zimaganiziridwa kuti zimagwirizana ndi unit, momwe munthuyo amasiyanitsa mwachindunji mzere wa 10 kuchokera mtunda wa mamita asanu. Nthawi zina pali anthu omwe ali ndi maonekedwe oposa 1, omwe amatha kusiyanitsa mizere pansi pa khumi.

Panthawiyi, kuwonjezera pa matebulo, njira zamakono zogwiritsira ntchito maonekedwe owonetserako zimagwiritsidwanso ntchito, pogwiritsira ntchito refractometers yapadera ndi zipangizo zina. Njira zoterozo zimaonedwa kuti ndi zolondola komanso zolinga.

Cheke ikuchitika mosiyana pa diso lirilonse, kutseketsa chachiwiri, monga chiwonetsero chowonekera chingakhale chosiyana pa diso lililonse.

Zinthu zomwe zimakhudza zooneka bwino

Maso a anthu makamaka amadalira zinthu zakunja: kotero mu kuwonetsera kwathunthu timawona bwino kusiyana ndi mdima, masomphenya owona nthawi zambiri amakhala abwino kuposa ozungulira, komanso masomphenya amamveka bwino kwambiri, ndipo mdima ndi wakuda mumdima, womwe umagwirizana ndi zochitika maso ndi makonzedwe a michere ndi ndodo. Koma izi ndi zachirengedwe, ndipo kawirikawiri sizikusokoneza kuyang'ana kwa maonekedwe acuity pa se.

Koma kuchepetsa kupweteka kwa maso ndizovuta kwambiri zomwe zingayambidwe chifukwa cha kusintha kwa msinkhu, komanso zobadwa, kupweteka kwamaso, komanso chifukwa cha matenda kapena nkhawa.

Kubwezeretsedwa kwa zithunzi zooneka bwino

Chifukwa cha kufunikira ndi kufunika kwa njira zoterezi, njira zambiri tsopano zikulengezedwa zomwe zingabweretseretu maonekedwe abwino.

1. Zochita za maso. Poganizira mmene maso amachitira poyera tsiku ndi tsiku, masewera olimbitsa thupi amenewa angakhale othandiza ngakhale kwa anthu amene alibe vuto la masomphenya komabe, makamaka chifukwa ndi losavuta. Tsekani maso anu, ndi kuwasungunula mosamala ndi zala zanu, mumagulu ozungulira. Kuwombera 10-12 nthawi, pofikira monga momwe mungathere. Tsekani maso anu ndikuwonetsere asanu ndi atatu kapena mabwalo. Kawirikawiri yang'anani maso anu, ndiye muwachepetse pansi, sungani maso anu kumanja - kumanzere. Masewera olimbitsa thupi amachitidwa kwa mphindi 10-15 kangapo patsiku.
2. Magalasi opititsa patsogolo maonekedwe abwino. Magalasi apadera, opangidwa ndi mabowo ang'onoting'ono, omwe amathandiza kuchepetsa kutopa kwa maso ndi kusintha maonekedwe a maso pamene disolo limakhala losalala.
3. Kukonzekera. Choyamba, kukonzekera kotereku kumaphatikizapo mavitamini ambirimbiri, zowonjezera za LHC ndi mankhwala ena omwe amawathandiza kuti azigwiritsa ntchito mankhwala a retina komanso kusintha ntchito yake. Kulimbitsa maonekedwe a mankhwalawa sikuthandiza, koma wokhoza kuteteza kuwonongeka kowonjezereka ndikukhazikika. Komanso, pali mankhwala angapo (ogwiritsidwa ntchito moyenera malinga ndi mankhwala a ophthalmologist) omwe amathandiza kuti azisangalala ndi minofu ya maso ndipo potero amachepetsa magazi m'maso.

Kawirikawiri, ngati maonekedwe amatha kuchepa kwambiri, njira yokhayo yothandiza ndi opaleshoni, ndipo njira zotsalira (masewera olimbitsa maso, madontho, etc.) zimatha kupereka pang'ono chabe. Komabe, iwo ndi njira zofunika kwambiri popewera ndi kupewa kutayika kwina kwa masomphenya.
