Mitundu yopitilira 150 ya myopia yadziwika m'zaka zaposachedwa.Jini limodzi lokha lokhalo silingabweretse vutoli, koma anthu omwe ali ndi angapo mwa majiniwa ali ndi chiopsezo chachikulu chokhalira maso.
Kuyang'ana pafupi - pamodzi ndi zolembera za majini izi - zitha kuperekedwa kuchokera ku m'badwo umodzi kupita ku wina.Ngati kholo limodzi kapena onse awiri akuwona pafupi, pamakhala mwayi waukulu woti ana awo azidwala myopia.
Makhalidwe a masomphenya
Majini ndi gawo limodzi chabe la chithunzithunzi cha myopia.Kuyang'ana pafupi kungayambitsenso kapena kuipiraipira chifukwa cha masomphenya ena - makamaka, kuyang'ana zinthu zomwe zili pafupi kwa nthawi yaitali.Izi zikuphatikizapo kusasinthasintha, kuthera maola ambiri mukuwerenga, kugwiritsa ntchito kompyuta, kapena kuyang'ana pa foni yamakono kapena piritsi.
Pamene mawonekedwe a diso lanu salola kuwala kuyang'ana bwino pa retina, akatswiri a maso amatcha izi kuti ndi zolakwika.Kornea ndi mandala anu amagwirira ntchito limodzi kupindikiza kuwala pa retina yanu, mbali yomwe imamva kuwala kwa diso, kuti mutha kuwona bwino.Ngati diso lanu, cornea kapena mandala anu sali bwino, kuwala kumapindika kapena kusayang'ana pa retina momwe zimakhalira nthawi zonse.
Ngati mukuwona pafupi, diso lanu ndi lalitali kwambiri kuchokera kutsogolo kupita kumbuyo, kapena cornea yanu ndi yopindika kwambiri kapena pali vuto ndi mawonekedwe a lens yanu.Kuwala komwe kumabwera m'diso lanu kumayang'ana kutsogolo kwa retina m'malo moyang'ana momwemo, zomwe zimapangitsa kuti zinthu zakutali ziziwoneka ngati zosamveka.
Ngakhale myopia yomwe ilipo nthawi zambiri imakhazikika akakula, zizolowezi zomwe ana ndi achinyamata amakhazikitsa zisanachitike zimatha kukulitsa kuwoneratu.
