Chimodzi mwa zinthu zofunika kuziganizira pogula magalasi olembedwa ndi dokotala ndi makulidwe a magalasi.Kuchuluka kwa magalasi anu sikumangokhudza maonekedwe a magalasi anu, komanso chitonthozo ndi ntchito yawo.Kuti muwonetsetse kuti mwasankha bwino, ndikofunikira kumvetsetsa zomwe zimakhudza makulidwe a magalasi agalasi.
Chinthu choyamba choyenera kuganizira ndi mphamvu ya mankhwala.Pamene mankhwala anu akuchulukirachulukira, m'pamenenso mumafunika magalasi okhuthala.Zolemba zamphamvu nthawi zambiri zimakhala zokhotakhota zolimba, zomwe zimafunikira zinthu zambiri kuti ziwongolere maso.Ngati muli ndi mankhwala apamwamba, mungafune kuganizira magalasi apamwamba.Magalasi awa adapangidwa mwapadera kuti akhale ochepa komanso opepuka kuposa magalasi achikhalidwe, kuwapanga kukhala chisankho chabwino kwambiri kwa anthu omwe ali ndi myopia yayikulu.
Mfundo ina yofunika kuiganizira ndi magalasi.Zida zosiyanasiyana zamagalasi zimakhala ndi ma refractive indexes osiyanasiyana, omwe amakhudza momwe kuwala kumapindikira pamene akudutsa mu mandala.Nthawi zambiri, zida zokhala ndi index yayikulu zimakhala ndi index yotsika kwambiri, zomwe zikutanthauza kuti zimatha kupindika bwino kwambiri.Choncho, magalasi apamwamba kwambiri ndi ochepa kwambiri kusiyana ndi magalasi apulasitiki amtundu wa mphamvu zomwezo.
Kuphatikiza apo, kusankha mafelemu kudzakhudzanso makulidwe a magalasi owonera.Mafelemu opanda mipiringidzo amatha kukwanira magalasi akukhuthala, pomwe mafelemu opanda rimle kapena ma semi-rimless amafunikira magalasi owonda kuti agwirizane bwino.Chifukwa chake ngati mukufuna mtundu wina wa chimango, onetsetsani kuti mukuganizira momwe zimakhudzira makulidwe a magalasi anu.
