Iwo ali mu chipinda cha mankhwala, bukhu la mabuku, ngakhale sitolo ya dola. Ndipotu, zikuwoneka kuti paliponse pamene mukuwerenga kuti muchitike, mungapeze magalasi owerengera otsika mtengo (OTC). Koma kodi izi zimakhala zotetezeka bwanji, poyerekeza ndi magalasi omwe angathe kuwononga nthawi zambiri? Pano pali mawonekedwe a magalasi omwe amawongoledwa okonzekera kuchita, komanso ngati muyenera kuyesera.
Diso lokalamba
Anthu ambiri amakumana ndi kusintha kwa masomphenya awo pamene akulamba. Zomwe zimakhala zosaoneka komanso zooneka bwino zodzikweza zimatchulidwa kuti "matenda afupipafupi", kapena kufunika kokhala patali chifukwa cha kuchepa kwa kuyang'ana pa zinthu pafupi. Mwalamulo, amadziwika kuti presbyopia .
Presbyopia imapezeka chifukwa cha kuuma kwa diso la diso, kusiya mandala omwe sungathe kugwa kuti aganizire, komanso chifukwa cha kusintha kwa minofu yomwe imayendetsa disolo.
Monga momwe mungapezere, chirichonse chomwe chimapangitsa kuti kusindikizidwa kwabwino kukuthandizire-kaya ndi galasi lokulitsa, kapena kungoyang'ana kamera ya foni yanu. Kupatsa mphamvu powerenga magalasi kumapangitsa zinthu zing'onozing'ono ndi mawu pa tsamba zikuwoneka kuti ndi zosavuta kuziwona.
Magalasi Oyang'anira Magetsi / Okonzekera Okonzeka
Magalasi ovomerezeka angathe kukonza mavuto angapo, kuphatikizapo kuyang'anitsitsa (kuyang'ana zinthu zakutali), kuyang'anitsitsa (kuyang'ana zinthu zomwe ziri pafupi), ndi astigmatism .
Astigmatism imachitika pamene kutsogolo kwa diso kukuwoneka ngati mpira wa mpira wozungulira, ndipo zingayambitse zithunzi zolakwika. Kuonjezera apo, chifukwa magalasi oyenera adakonzedweratu kwa inu, malo opangira malingaliro aliwonse (komwe diso la openi lidzapindula bwino) likugwirizana ndi malo a ophunzira anu onse.
Owerenga okonzeka, mosiyana, ali opangidwa ndi misala ndipo amapanga cholinga chimodzi chokha-kukuza fano patsogolo panu. Iwo sangakonzekeretu kuyang'anitsitsa kapena kusokoneza.
Kodi Owerenga Owerenga Amakhala Otetezeka?
Natalie Hutchings, Pulofesa Wothandizira pa Yunivesite ya Waterloo's School of Optometry ndi Vision Science, akuti kuwerenga magalasi omwe amapangidwa mobwerezabwereza sikungakupangitseni inu kukhala akhungu, koma angayambitse mavuto ena.
"Kwa okalamba ambiri, magalasi owerengera awa adzakhala abwino, ndipo sangathe kuwononga maso anu mosalekeza," akutero. "Ngati mankhwala anu sali amphamvu kwambiri, ndipo mumagwiritsa ntchito nthawi zochepa chabe-kuwerenga maulendo apamtima pa golosale, mwachitsanzo-magalasi otsika mtengo sayenera kuvulaza."
Hutchings amanenanso kuti ngati muli ndi vuto la maso kapena kupwetekedwa mutu, muyenera kukhala ndi diso lanu dokotala kuti ayese magalasi anu owerenga. Amatchula kafukufuku wochokera ku yunivesite ya Cincinnati pofufuza owerenga omwe amapangidwa ndi anthu ambiri. Woperekedwa ku bungwe la Research in Vision ndi Ophthalmology (ARVO) pachaka msonkhano mu May 2013, maphunziro osindikizidwa anafufuza awiri awiri a owerenga okonzeka. Pafupifupi kotala la awiriawiri (24 peresenti) adapezeka kuti ali ndi malo opangira mawotchi oposa 2, zomwe akatswiri ofufuza Constance West ndi David Hunter adatsiriza zikhoza kuyambitsa eyestrain ndi masomphenya awiri mwa anthu akuluakulu.
Kumadzulo ndi Hunter amalangiza akatswiri a maso kuti azindikire malo opangira opaleshoni ndi kukulitsa mphamvu ya odwala awo OTI.
Malangizo Ogwiritsira Ntchito Mopepuka Magalasi Owerenga Okonzeka
Natalie Hutchings amapereka malangizo awa: Kugwiritsa ntchito magalasi oyenera kupanga:
- Sankhani mphamvu zokhazo zomwe zimakulolani kuti muwerenge chinachake pamtunda wapatali. Kulimba kwambiri sikokwanira bwino.
- Fufuzani magalasi a thovu, mafunde, kapena zinthu zina zosokoneza zomwe zingakuvutitseni maso anu.
- Musagwiritse ntchito owerenga owonjezera pa ntchito pa kompyuta; mumakhala pawindo kusiyana ndi momwe mumachitira kuchokera m'buku kapena m'magazini.
- Gwiritsani ntchito owerengawa kuti azigwira ntchito mwamsanga, monga kuwerenga lemba pa golosale.
- Ngati mukuyamba kupweteka mutu, tengani magalasi anu kwa dokotala wa maso kuti owerenga athe kuyesedwa.
Pomaliza, musamayese kufufuza maso nthawi zonse ngakhale owerenga OTC akugwira ntchito. Kuwona zooneka bwino ndi mbali imodzi yokha ya masomphenya yomwe katswiri wa zamagetsi kapena optometrist adzayesa. Angathenso kupeza mavuto omwe angakhale aakulu monga shuga ndi maselo a retina , kumayambiriro pomwe simungakhale ndi zizindikiro.
