Ngati mwangoyamba kumene kuyankhulana ndi lens, mwina munadabwa ndi ndalama yanu yomaliza. Odwala nthawi zambiri amadzifunsa chifukwa chake mtengo wa lens wokuyezetsa lens umakhala waukulu kuposa woyezetsa maso nthawi zonse. Chifukwa chakuti odwala oyenerera amakhala ndi masitepe angapo komanso nthawi yowonjezera. Mwachindunji, pali zinthu zingapo zomwe zingapangitse maziko:
Ngati Muli Watsopano kwa Othandizira
Ngati mukufuna kupempha makalenseni oyamba aja, muyenera kukhala ndi kafukufuku wokwanira kuti mutsimikizire kuti ndinu woyenera kuti muveke ojambula. Mudzafunsidwa kuti mudziwe zolinga zanu payekha komanso masomphenya. Mukhoza kungovala ojambula masewera kamodzi pa sabata, kapena mwinamwake mungafune kuvala tsiku ndi tsiku kuti aziwerenga ndi kutseka ntchito. Chifukwa pali zosankha zambiri za lens, dokotala wabwino amamvetsera mwachidwi zolinga zanu ndikusankha lens yomwe imayendetsa bwino moyo wanu.
Mayesero ndi Njira Zowonjezereka
Dokotala wanu wa diso adzachita mayesero angapo kuti aone ngati maso anu ali ndi lens. Chiyeso chimodzi chofunika ndi malo osinthika , njira yomwe imatulutsa mbali zonse za cornea yanu. Zithunzi zojambula zithunzi zimasonyeza zotsatira zofanana ndi mapiri. Mitengo yowonjezera (yobiriwira) imasonyeza malo ochepetsetsa a mtundu wa cornea ndi ozizira (bluish) amaimira malo otsika.
Chifukwa chojambulira chinsalu chimakhala pa cornea mukalowa m'diso lanu, kupotola koyenera kumayenera kuyesedwa mwatcheru kuonetsetsa kuti ndibwino kwambiri.
Chiyeso china chofunika ndi kuunika kwa nyali . Pamene mayesowa amachitikira pakapita kafukufuku wamaso, dokotala wanu angakhale ndi nthawi yochulukirapo yowunikira nyali kwa wothandizira malonda.
Nthaŵi zina, mavuto a maso a zachipatala amadziwika omwe amafunika kuchiritsidwa asanapitirize ndi zoyenera.
Kuyikira Othandizira
Pambuyo pokambirana njira zosiyanasiyana zothandizana ndi lens , majekeseni enieni opatsirana angapangidwe m'maso mwanu. Dokotala wanu amatha kuyesa nyali ina yowunikira kuti ayang'ane ngati ali ndi lens yoyenera molondola, kuonetsetsa kuti kayendetsedwe kake kamakhala koyenera. Pambuyo pake, kuyesedwa koyang'ana kwa acuity kudzachitidwa kuti mudziwe momwe lens yolumikizira imakonzera masomphenya anu.
Ngati simunayambe kujambula malonda, mumaphunzitsidwa njira yoyenera kuwachotsera, kuchotsa, ndi kuwagwiritsa ntchito. Madokotala ochuluka a maso amayang'ana kwambiri kufunika kwa ukhondo, ukhondo, ndi kuteteza thupi . Dokotala wanu adzakulolani kuti muzivala ma lens otha kwa sabata ndikubwezeretsani kuti muzitsatira. Paulendo wotsatira, dokotala wanu adzayambiranso makalenseni ogwirizana ndi kuthetsa mavuto. Mwina lens latsopano lidzayesedwa kapena mankhwalawa adzatsirizidwa. Ngati masomphenya anu ndi chitonthozo sali zokhutiritsa, maulendo ena otsogolera angayambe. Mitundu ina ya lensulo, monga lamoto yamakono yokonzetsa astigmatism kapena lamalensi zamakono pofuna kukonza presbyopia, amatha kutenga nthawi yambiri kuti akwaniritse bwino.
Malingaliro oyenerera ogwirizana ali onse sayansi ndi luso lomwe limafuna luso linalake la luso. Ndalama zowonongeka kwa lens ndi kasamalidwe kawirikawiri zimakhala pakati pa $ 15 ndi $ 160 pamwamba pa ndalama zowonongeka pamaso nthawi zonse , malingana ndi mtundu wa malingaliro osowa. Nthawi ndi maulendo owonjezera, mayesero apadera, ndi luso la adokotala ndi zinthu zomwe sizili mbali ya nthawi zonse yathanzi la maso ndi masomphenya a masomphenya. Mankhwala a maso, thanzi la maso, zolinga zaumwini, ndi mtundu wa mankhwala amachititsa kuti anthu azitha kuyang'anirana ndi malingaliro osiyana ndi odwala onse.
