Ngati mumakonda kuvala ma lens m'malo mwa magalasi kuti muwone bwino, pali mitundu ingapo yomwe mungasankhe.
Ma lens olimba ndi ofewa ali ndi ubwino ndi zovuta zake.Zomwe zili zoyenera kwa inu zingadalire zosowa zanu zamasomphenya, moyo wanu komanso zomwe mumakonda.
Ngati mukuganiza zokhala ndi ma lens olimba, werengani kuti mudziwe zabwino ndi zoyipa za magalasiwa komanso momwe mungawagwiritsire ntchito mosamala.
Ma lens ogwiritsidwa ntchito kwambiri omwe amagwiritsidwa ntchito kwambiri ndi magalasi okhwima a gas permeable (RGP).Amakhala omasuka komanso otetezeka kuvala kusiyana ndi mitundu yakale ya magalasi olimba, monga ma lens a polymethylmethacrylate (PMMA).
Magalasi a RGP amapangidwa ndi zinthu zapulasitiki zosinthika zomwe nthawi zambiri zimakhala ndi silicone. Zinthu zopepukazi zimalola kuti mpweya udutse mwachindunji kudzera m'diso kupita ku diso lanu.
Kornea yanu ndi gawo lakunja la diso lanu lowonekera kwambiri. Chisoni chanu chimawona kuwala ndipo chimagwira ntchito ngati lens ya kunja kwa diso lanu. Khoma lanu likapanda kupeza mpweya wokwanira, limatupa. mavuto ena a maso.

Ma lens a PMMA salola kuti mpweya udutse m'magalasi.Njira yokhayo yomwe mpweya ungafikire ku cornea ndi ngati misozi imatuluka pansi pa lens nthawi zonse pamene mukuphethira.
Pofuna kulola misozi kuyenda pansi pa lens, ma lens a PMMA ndi ochepa kwambiri kukula kwake. Komanso, payenera kukhala kusiyana pakati pa lens ndi cornea. , makamaka pochita masewera olimbitsa thupi.
Chifukwa magalasi a RGP amalola mpweya kudutsamo, magalasi awa ndi akulu kuposa ma lens a PMMA ndipo amaphimba diso kwambiri.
Kuonjezera apo, m'mphepete mwa magalasi a RGP amagwirizana kwambiri ndi maso anu.Izi zimawapangitsa kukhala omasuka kuvala kuposa zitsanzo zakale.Zimapangitsanso kuti magalasi azikhala m'maso mwanu motetezeka.
Zolakwika za retina zimachitika pamene mawonekedwe a diso lanu amalepheretsa kuwala komwe kukubwera kuti kusayang'ane bwino pa retina.
Kuvala magalasi olimba a RGP kumatha kukonza zolakwika zingapo, kuphatikiza:
Ma lens olimba a RGP ali ndi maubwino angapo kuposa ma lens ofewa. Tiyeni tiwone maubwino awa mwatsatanetsatane:
Ma lens olimba a RGP alinso ndi zovuta zina.Nazi zovuta zina zomwe zimachitika ndi magalasi awa.
Ngati mukufuna kuti magalasi olimba azitha kukhala nthawi yayitali, ndikofunika kuwasamalira bwino.Kusamalira bwino magalasi anu kungathandizenso kuchepetsa chiopsezo cha matenda a maso kapena zokopa za cornea.
Magalasi olimba a gas permeable (RGP) ndi omwe amadziwika kwambiri a lens okhwima omwe amalembedwa masiku ano. Amapereka masomphenya akuthwa kwambiri kuposa ma lens ofewa.

Komanso, zinthu zina, kuphatikizapo astigmatism, zimatha kukonzedwa bwino ndi ma lens olimba.
Komabe, kuvala ma lens olimba nthawi zambiri kumatenga nthawi yayitali kuti azolowere, ndipo sangakhale omasuka ngati magalasi ofewa.Lankhulani ndi dokotala wa maso anu kuti mudziwe mtundu wa lens womwe uli woyenera kwa inu ndi masomphenya anu.
Kusambira ndi magalasi olumikizirana kungakuthandizeni kuwona bwino, koma kumawonjezera chiwopsezo chamavuto ena okhudzana ndi maso, kuyambira diso louma mpaka lalikulu ...
Ma Contacts Ochotsera amapereka mitundu yambiri, mitengo yotsika, komanso kusakatula tsamba lawebusayiti kosavuta.Kodi chinanso choti mudziwe apa.
Pali malo ambiri ogulira magalasi pa intaneti.Ena ali ndi masitolo ogulitsa komwe mumatha kugulanso. Ena amadalira zotengera zenizeni komanso zoyeserera zapakhomo.
Ngati mukufuna kugula ma lens pa intaneti, masamba omwe ali pamndandandawu ali ndi mbiri yokhazikika yokhutiritsa makasitomala komanso kunyamula magalasi apamwamba…
