Ma Bifocal akwera chifukwa cha kuchuluka kwa kufunikira kwa zinthu panthawi yotentha, chithandizo cha ndalama chakhala champhamvu, ndipo mitengo ya zitsulo yapitirira kukwera. , mantha a kufunikira kwakukulu kwa zinthu zachitsulo kwakula, ntchito zobwezeretsanso msika zawonjezeka, kupanga zitsulo zopanda mafuta tsiku ndi tsiku kwatsika, kuitanitsa zitsulo zachitsulo kwatsika, kugulitsa nthaka kwayamba, ndipo msika wa malo ogulira zinthu uli wokhazikika komanso wamphamvu. Kuchokera pamalingaliro omveka bwino, mitengo ya zitsulo ikuyembekezeka kukhala yokhazikika komanso yolimba mawa.
